the Successful Bidder, nor shall they be accepted as a basis for any claims whatsoever

Section 11. Bid Quantities
11.1 Quantities given in the Bid Schedule, while estimated from the best information
available, are approximate only. Payment for unit price items shall be based on the
actual number of units installed for the Work. Bids shall be compared on the basis of
number of units stated in the Bid Schedule as set forth in the Bidding Documents. Said
unit prices shall be multiplied by the bid quantities for the total Bid price. Any Bid not
conforming to this requirement may be rejected. Special attention to all Bidders is
called to this provision, because if conditions make it necessary or prudent to revise the
unit quantities, the unit prices will be fixed for such increased or decreased quantities.
Compensation for such additive or subtractive changes in the quantities shall be limited
to the unit prices in the Bid. Subsequent to the issuance of a notice to proceed, the
Project Manager and the Successful Bidder shall have the discretion to re-negotiate any
unit price(s) where the actual quantity varies by more than 25% from the estimate at the
time of bid.
11.2 Alternate Bid PricinQ: In the event that alternate pricing is requested, it is an
expressed requirement of the bid invitation to provide pricing for all alternates as listed.
The omission of a response or a no-bid or lack of a submitted price may be the basis for
the rejection of the submitted bid response. All bids responses received without pricing
for all alternates as listed will be considered technically non-responsive and will not be
considered for award.
Section 12. Award of Contract
12.1 Any prospective bidder who desires to protest any aspect(s) or provision(s) of the
bid invitation (including the form of the bid documents or bid procedures) shall file their
protest with the Purchasing Director prior to the time of the bid opening strictly in
accordance with Owner's then current Purchasing Policy.
12.2 Statement of Award: The Award of Contract shall be issued to the lowest,
responsive and qualified Bidder determined by the base bid, and any, or all, selected
alternates, and the Owner's investigations of the Bidder. In determining the lowest,
responsive and qualified bidder, the Owner shall consider the capability of the Bidder to
perform the contract in a timely and responsible manner. When the contract is awarded
by Owner, such award shall be evidenced by a written Notice of Award, signed by a
Purchasing Agent of the Owner's Purchasing Department or his or her designee and
delivered to the intended awardee or mailed to awardee at the business address shown
in the Bid.
Local Vendor Preference: The Collier County Board of County Commissioners has
adopted a Local Preference "Right to Match" policy to enhance the opportunities of local
businesses to receive awards of Collier County contracts.
A "local business" is defined as a business that has a valid occupational license issued
by either Collier or Lee County for a minimum of one (1) year prior to a Collier County
bid or proposal submission that authorizes the business to provide the commodities or
GC-IB-5
IDA
;.\1
,It
services to be purchased, and a physical business address located within the limits of
Collier or Lee Counties from which the vendor operates or performs business. Post
Office Boxes are not verifiable and shall not be used for the purpose of establishing said
physical address. In addition to the foregoing, a vendor shall not be considered a "local
business" unless it contributes to the economic development and well-being of either
Collier or Lee County in a verifiable and measurable way. This may include, but not be
limited to, the retention and expansion of employment opportunities, the support and
increase to either Collier or Lee County's tax base, and residency of employees and
principals of the business within Collier or Lee County. Vendors shall affirm in writing
their compliance with the foregoing at the time of submitting their bid or proposal to be
eligible for consideration as a "local business" under this section.
When a qualified and responsive, non-local business submits the lowest price bid, and
the bid submitted by one or more qualified and responsive local businesses is within ten
percent (10%) of the price submitted by the non-local business, then the local business
with the apparent lowest bid offer (i.e. the lowest local bidder) shall have the opportunity
to submit, an offer to match the price(s) offered by the overall lowest, qualified and
responsive bidder. In such instances, staff shall first verify if the lowest non-local bidder
and the lowest local bidder are in fact qualified and responsive bidders. Next, the
Purchasing Department shall determine if the lowest local bidder meets the
requirements of Section 287.087 F.S.
If the lowest local bidder meets the requirements of 287.087, F.S., the Purchasing
Department shall invite the lowest local bidder to submit a matching offer to the
Purchasing Department which shall be submitted within five (5) business days
thereafter. If the lowest local bidder submits an offer that fully matches the lowest bid
from the lowest non-local bidder tendered previously, then award shall be made to the
local bidder. If the lowest local bidder declines or is unable to match the lowest non
local bid price(s), then award will be made to the lowest overall qualified and responsive
bidder. If the lowest local bidder does not meet the requirement of Section 287.087 F.S.
and the lowest non-local bidder does, award will be made to the bidder that meets the
requirements of the reference state law.
Bidder must complete and submit with their bid response the Affidavit for Claiming
Status as a Local Business which is included as part of this solicitation.
Failure on the part of a Bidder to submit this Affidavit with their bid response will
preclude said Bidder from being considered for local preference on this
solicitation.
A Bidder who misrepresents the Local Preference status of its firm in a bid submitted to
the County will lose the privilege to claim Local Preference status for a period of up to
one year.
The County may, as it deems necessary, conduct discussions with responsible bidders
determined to be in contention for being selected for award for the purpose of

Upon notification that its Bid has been awarded, the Successful Bidder will execute the
Agreement form attached to the Bidding Documents within ten (10) calendar days and
deliver the Surety Bond or Bonds and Insurance Certificates as required by the Contract
Documents. The bid security attached is to become the property of the Owner in the
event the Agreement, Insurance Certificates and Bonds are not executed and delivered
to Owner within the time above set forth, as liquidated damages, for the delay and
additional expense to the Owner, it being recognized that, since time is of the essence,
Owner will suffer financial loss if the Successful Bidder fails to execute and deliver to
Owner the required Agreement, Insurance Certificates and Bonds within the required
time period. In the event of such failure, the total amount of Owner's damages, will be
difficult, if not impossible, to definitely ascertain and quantify. It is hereby agreed that it
is appropriate and fair that Owner receive liquidated damages from the Successful
Bidder in the event it fails to execute and deliver the Agreement, Insurance Certificates,
and Bonds as required hereunder. The Successful Bidder hereby expressly waives and
relinquishes any right which it may have to seek to characterize the above noted
liquidated damages as a penalty, which the parties agree represents a fair and
reasonable estimate of Owner's actual damages at the time of bidding if the Successful
Bidder fails to execute and deliver the Agreement, Insurance Certificates, and Bonds in
a timely manner.
Upon receipt of the Notice of Award, the undersigned proposes to commence work at
the site within 5 calendar days from the commencement date stipulated in the written
Notice to Proceed unless the Project Manager, in writing, subsequently notifies the
Contractor of a modified (later) commencement date. The undersigned further agrees to
substantially complete all work covered by this Bid within the calendar days specified
below, computed by excluding the commencement date and including the last day of
such period, and to be fully completed to the point of final acceptance by the Owner
within specified consecutive calendar days (see below) after Substantial Completion,
computed by excluding commencement date and including the last day of such period.

STATEMENT OF QUALIFICATIONS AND EXPERIENCE OF BIDDER
1. Describe all project litigation, mediation and arbitration initiated by the bidder or one of its affiiiates on
construction projects in the past eight years. Identify the current status of Initiated action.
In the past eight years we had only one arbitration initiated by a subcontractor on a project for the
South Florida Water Management District. This arbitration was due to different interpretations of a
poorly written and contradicting set of specifications regarding the inclusion of door hardware costs in
an allowance item. The arbitration took one day to resolve and the agreed compensation was roughly
$90,000.00. Douglas N. Higgins, Inc. contributed money to the settlement to get the matter resolved.
We are In good standing with the South Florida Water Management District, we are on their
prequalified contractors list, and continue to do work for them. This initiated action is closed. We
have completed over $200,000,000.00 in work in the last eight years and this is the only initiated
action and it was resolved amicably,
2. Describe all litigation, mediation, arbitration, regulatory citations and hearings involving the bidder or
one of its affiiiates involving labor disputes, discrimination complaints or safety violations on
construction projects in the last eight years.
We have had no labor disputes or discrimination complaints in the last eight years. We had OSHA
citation number 307297929 in May of 2004 regarding trench safety concerns with a penalty amount
of $3,038.00. We had OSHA citation number 311083570 in July of 2007 regarding confined space
concerns with a penalty amount of $3,750,00. Both of these citations were addressed and our safety
is continually improving. Our current Experience Modification Rating (EMR) rating is significantly
better than the industry standard and is currently at 0.86, This rating shows our lack of accidents and
injuries and allows us to pass on our workman's compensation savings on to the Owner.
3. Identify and describe in detail all construction projects in the last eight years involving the bidder or one
of its affiliates for which liquidated damages were assessed by the project owner on any partial or final
progress payment, even if those damages were not ultimately collected by that owner.
We have had only one project in the last eight years where we were charged iiquidated damages. This
project was for the South Florida Water Management District. We had a significant subcontractor miss
his time commitments and cause the project to miss the substantial completion date. We settled with
the South Florida Water Management District and passed the damages on to our Subcontractor. We
fulfilled our obiigations under the contract and did not take missing the schedule and paying the
damages lightly. We are in good standing with the South Florida Water Management District, we are
on their prequalified contractors list, and continue to do work for them. This inititated action is closed.

Enterprises. Both of these subcontractors are local to Collier County. Gulf States Electrical is an
electrical and instrumentation subcontractor and has completed 80% of our Electrical and
Instrumenation work on the projects listed in our experience documentation. More specifically Gulf
States Electrical was part of our successful team for the two similar projects listed, the Marco Island
Wastewater Treatment Plant Expansion and the Golden Gate WWTP and Injection Pump Station
project.
Earthtech Enterprises is a local earthwork subcontractor that has completed 90% of our subcontracted
earthwork on the projects listed in our experience documentation. More specifically Earthtech was
part of our successful team that completed the Gateway Triangle Stormwater Improvements for
Collier County in 2008. Eathtech Enterprises, using their local knowledge and workforce, will be critical
to the completion of the critical timeline required for the pond work

Contractor prior to the Commencement Date shall be at the sole risk of Contractor.
Contractor shall achieve Substantial Completion within the calendar days from the
Commencement Date (herein "Contract Time") (specified below). The date of
Substantial Completion of the Work (or designated portions thereof) is the date certified
by the Design Professional when construction is sufficiently complete, in accordance
with the Contract Documents, so Owner can occupy or utilize the Work (or designated
portions thereof) for the use for which it is intended. Contractor shall achieve Final
Completion within the specified calendar days (see below) after the date of Substantial
Completion. Final Completion shall occur when the Agreement is completed in its
entirety, is accepted by the Owner as complete and is so stated by the Owner as
completed

As used herein and throughout the Contract Documents, the phrase "Project Manager"
refers to the Owner's duly authorized representative and shall mean the Division
GC-CA-2
10 A ~
Administrator or Department Director, as applicable, acting directly or through duly
authorized representatives.
B. Liquidated Damages in General.
Owner and Contractor recognize that, since time is of the essence for this Agreement,
Owner will suffer financial loss if Contractor fails to achieve Substantial Completion
within the time specified above, as said time may be adjusted as provided for herein. In
such event, the total amount of Owner's damages, will be difficult, if not impossible, to
definitely ascertain and quantify. Should Contractor fail to achieve Substantial
Completion within the number of calendar days established herein, Owner shall be
entitled to assess, as liquidated damages, but not as a penalty, (see table below) for
each calendar day thereafter until Substantial Completion is achieved. Further, in the
event Substantial Completion is reached, but the Contractor fails to reach Final
Completion within the required time period, Owner shall also be entitled to assess and
Contractor shall be liable for all actual damages incurred by Owner as a result of
Contractor failing to timely achieve Final Completion. The Project shall be deemed to
be substantially completed on the date the Project Manager (or at his/her direction, the
Design Professional) issues a Certificate of Substantial Completion pursuant to the
terms hereof. Contractor hereby expressly waives and relinquishes any right which it
may have to seek to characterize the above noted liquidated damages as a penalty,
which the parties agree represents a fair and reasonable estimate of the Owner's actual
damages at the time of contracting if Contractor fails to Substantially or Finally
Complete the Work within the required time periods.
Project Liquidated Damages
Per Day
1) Pond NO.2 $288,000 Flat Rate
i\ All other work $1,100.00 per dav
C. Computation of Time Periods.
When any period of time is referenced by days herein, it shall be computed to exclude
the first day and include the last day of such period. If the last day of any such period
falls on a Saturday or Sunday or on a day made a legal holiday by the law of the
applicable jurisdiction, such day shall be omitted from the computation, and the last day
shall become the next succeeding day which is not a Saturday, Sunday or legal holiday.
D. Determination of Number of Days of Default.
For all contracts, regardless of whether the Contract Time is stipulated in calendar days
or working days, the Owner will count default days in calendar days.
E. Right of Collection.
The Owner has the right to apply any amounts due Contractor under this Agreement or
any other agreement between Owner and Contractor, as payment on such liquidated
damages due under this Agreement in Owner's sole discretion. Notwithstanding
GC-CA-3
10 A ,
anything herein to the contrary, Owner retains its right to liquidated damages due under
this Agreement even if Contractor, at Owner's election and in its sole discretion, is
allowed to continue and to finish the Work, or any part of it, after the expiration of the
Contract Time including granted time extensions.
F. Completion of Work by Owner.
In the event Contractor defaults on any of its obligations under the Agreement and
Owner elects to complete the Work, in whole or in part, through another contractor or its
own forces, the Contractor and its surety shall continue to be liable for the liquidated
damages under the Agreement until Owner achieves Substantial and Final Completion
of the Work. Owner will not charge liquidated damages for any delay in achieving
Substantial or Final Completion as a result of any unreasonable action or delay on the
part of the Owner.
G. Final Acceptance by Owner.
The Owner shall consider the Agreement complete when the Contractor has completed
in its entirety all of the Work and the Owner has accepted all of the Work and notified
the Contractor in writing that the Work is complete. Once the Owner has approved and
accepted the Work, Contractor shall be entitled to final payment in accordance with the
terms of the Contract Documents.
H. Recovery of Damages Suffered by Third Parties.
Contractor shall be liable to Owner to the extent Owner incurs damages from a third
party as a result of Contractor's failure to fulfill all of its obligations under the Contract
Documents. Owner's recovery of any delay related damages under this Agreement
through the liquidated damages does not preclude Owner from recovering from
Contractor any other non-delay related damages that may be owed to it arising out of or
relating to this Agreement.

t~
The Vendor shall at its own expense, carry and maintain insurance coverage from responsible
companies duly authorized to do business in the State of Florida as set forth in EXHIBIT B of this
solicitation. The Vendor shall procure and maintain property insurance upon the entire project, if
required, to the full insurable value of the scope of work.
The County and the Vendor waive against each other and the County's separate Vendors,
Contractors, Design Consultant, Subcontractors, agents and employees of each and all of them, all
damages covered by property insurance provided herein, except such rights as they may have to the
proceeds of such insurance. The Vendor and County shall, where appropriate, require similar
waivers of subrogation from the County's separate Vendors, Design Consultants and Subcontractors
and shall require each of them to include similar waivers in their contracts.
Collier County shall be responsible for purchasing and maintaining its own liability insurance.
Certificates issued as a result of the award of this solicitation must identify "For any and all work
performed on behalf of Collier County."
The General Liability Policy provided by Vendor to meet the requirements of this solicitation shall
name Collier County, Florida, as an additional insured as to the operations of Vendor under this
solicitation and shall contain a severability of interests provisions.
Collier County Board of County Commissioners shall be named as the Certificate Holder. The
"Certificate Holder" should read as follows:
Collier County
Board of County Commissioners
Naples, Florida
The amounts and types of insurance coverage shall conform to the minimum requirements set forth in
EXHIBIT B with the use of Insurance Services Office (ISO) forms and endorsements or their
equivalents. If Vendor has any self-insured retentions or deductibles under any of the below listed
minimum required coverage, Vendor must identify on the Certificate of Insurance the nature and
amount of such seif- insured retentions or deductibles and provide satisfactory evidence of financial
responsibility for such obligations. All self-insured retentions or deductibles will be Vendor's sole
responsibility.
Coverage.@} shall be maintained without interruption from the date of commencement of the Work
until the date of completion and acceptance of the scope of work by the County or as specified in this
solicitation, whichever is longer.
The Vendor and/or its insurance carrier shall provide thirty (30) days written notice to the County of
policy cancellation or non-renewal on the part of the insurance carrier or the Vendor. The Vendor

Vendor hereunder, Vendor shall immediately take steps to have the aggregate limit reinstated to the
full extent permitted under such policy.
Should at any time the Vendor not maintain the insurance coverage~ required herein, the County
may terminate the Agreement or at its sole discretion shall be authorized to purchase such
coverage~ and charge the Vendor for such coverage~ purchased. If Vendor fails to reimburse the
County for such costs within thirty (30) days after demand, the County has the right to offset these
costs from any amount due Vendor under this Agreement or any other agreement between the
County and Vendor. The County shall be under no obligation to purchase such insurance, nor shall it
be responsible for the coverage~ purchased or the insurance company or companies used. The
decision of the County to purchase such insurance coverage~ shall in no way be construed to be a
waiver of any of its rights under the Contract Documents.
If the initial or any subsequently issued Certificate of Insurance expires prior to the completion of the
scope of work, the Vendor shall furnish to the County renewal or replacement Certificate(s) of
Insurance not later than ten (10) calendar days after the expiration date on the certificate. Failure of

GENERAL TERMS AND CONDITIONS
1. INTENT OF CONTRACT DOCUMENTS.
1.1 It is the intent of the Contract Documents to describe a functionally complete
Project (or portion thereof) to be constructed in accordance with the Contract
Documents. Any work, materials or equipment that may reasonably be inferred from
the Contract Documents as being required to produce the intended result shall be
supplied whether or not specifically called for. When words which have a well known
technical or trade meaning are used to describe work, materials or equipment, such
words shall be interpreted in accordance with that meaning. Reference to standard
specifications, manuals or codes of any technical society, organization or association or
to the laws or regulations of any governmental authority having jurisdiction over the
Project, whether such reference be specific or by implication, shall mean the latest
standard specification, manual, code, law or regulation in effect at the time the Work is
performed, except as may be otherwise specifically stated herein.
1.2 If before or during the performance of the Work Contractor discovers a conflict,
error or discrepancy in the Contract Documents, Contractor immediately shall report
same to the Project Manager in writing and before proceeding with the Work affected
thereby shall obtain a written interpretation or clarification from the Project Manager;
said interpretation or clarification from the Project Manager may require Contractor to
consult directly with Design Professional or some other third party, as directed by
Project Manager. Contractor shall take field measurements and verify field conditions
and shall carefully compare such field measurements and conditions and other
information known to Contractor with the Contract Documents before commencing any
portion of the Work.
1.3 Drawings are intended to show general arrangements, design and extent of Work
and are not intended to serve as shop drawings. Specifications are separated into
divisions for convenience of reference only and shall not be interpreted as establishing
divisions for the Work, trades, subcontracts, or extent of any part of the Work. In the
event of a discrepancy between or among the drawings, specifications or other Contract
Document provisions, Contractor shall be required to comply with the provision which is
the more restrictive or stringent requirement upon the Contractor, as determined by the
Project Manager. Unless otherwise specifically mentioned, all anchors, bolts, screws,
fittings, fillers, hardware, accessories, trim and other parts required in connection with
any portion of the Work to make a complete, serviceable, finished and first quality
installation shall be furnished and installed as part of the Work, whether or not called for
by the Contract Documents.
2. INVESTIGATION AND UTILITIES.
2.1 Subject to Section 2.3 below, Contractor shall have the sole responsibility of
satisfying itself concerning the nature and location of the Work and the general and
local conditions, and particularly, but without limitation, with respect to the following:
GC-CA-J-t
10 A .~
those affecting transportation, access, disposal, handling and storage of materials;
availability and quality of labor; water and electric power; availability and condition of
roads; work area; living facilities; climatic conditions and seasons; physical conditions at
the work-site and the project area as a whole; topography and ground surface
conditions; nature and quantity of the surface materials to be encountered; subsurface
conditions; equipment and facilities needed preliminary to and during performance of
the Work; and all other costs associated with such performance. The failure of
Contractor to acquaint itself with any applicable conditions shall not relieve Contractor
from any of its responsibilities to perform under the Contract Documents, nor shall it be
considered the basis for any claim for additional time or compensation.
2.2 Contractor shall locate all existing roadways, railways, drainage facilities and
utility services above, upon, or under the Project site, said roadways, railways, drainage
facilities and utilities being referred to in this Sub-Section 2.2 as the "Utilities".
Contractor shall contact the owners of all Utilities to determine the necessity for
relocating or temporarily interrupting any Utilities during the construction of the Project.
Contractor shall schedule and coordinate its Work around any such relocation or
temporary service interruption. Contractor shall be responsible for properly shoring,
supporting and protecting all Utilities at all times during the course of the Work. The
Contractor is responsible for coordinating all other utility work so as to not interfere with
the prosecution of the Work (except those utilities to be coordinated by the Owner as
may be expressly described elsewhere in the Contract Documents).
2.3 Notwithstanding anything in the Contract Documents to the contrary, if conditions
are encountered at the Project site which are (i) subsurface or otherwise concealed
physical conditions which differ materially from those indicated in the Contract
Documents or (ii) unknown physical conditions of an unusual nature, which differ
materially from those ordinarily found to exist and generally recognized as inherent in
construction activities of the character provided for in the Contract Documents, and
which reasonably should not have been discovered by Contractor as part of its scope of
site investigative services required pursuant to the terms of the Contract Documents,
then Contractor shall provide Owner with prompt written notice thereof before conditions
are disturbed and in no event later than three (3) calendar days after first observance of
such conditions. Owner and Design Professional shall promptly investigate such
conditions and, if they differ materially and cause an increase or decrease in
Contractor's cost of, or time required for, performance of any part of the Work, Owner
will acknowledge and agree to an equitable adjustment to Contractor's compensation or
time for performance, or both, for such Work. If Owner determines that the conditions at
the site are not materially different from those indicated in the Contract Documents or
not of an unusual nature or should have been discovered by Contractor as part of its
investigative services, and that no change in the terms of the Agreement is justified,
Owner shall so notify Contractor in writing, stating its reasons. Claims by Contractor in
opposition to such determination by Owner must be made within seven (7) calendar
days after Contractor's receipt of Owner's written determination notice. If Owner and
Contractor cannot agree on an adjustment to Contractor's cost or time of performance,
the dispute resolution procedure set forth in the Contract Documents shall be complied
with by the parties.

3. SCHEDULE.
3.1 The Contractor, within ten (10) calendar days after receipt of the Notice of Award,
shall prepare and submit to Project Manager, for their review and approval, a progress
schedule for the Project (herein "Progress Schedule"). The Progress Schedule shall
relate to all Work required by the Contract Documents, and shall utilize the Critical Path
method of scheduling and shall provide for expeditious and practicable execution of the
Work within the Contract Time. The Progress Schedule shall indicate the dates for
starting and completing the various stages of the Work.
3.2 The Progress Schedule shall be updated monthly by the Contractor. All monthly
updates to the Progress Schedule shall be subject to the Project Manager's review and
approval. Contractor shall submit the updates to the Progress Schedule with its
monthly Applications for Payment noted below. The Project Manager's review and
approval of the submitted Progress Schedule updates shall be a condition precedent to
the Owner's obligation to pay Contractor.
3.3 All work under this Agreement shall be performed in accordance with the
requirements of all Collier County Noise Ordinances then in effect. Unless otherwise
specified, work will generally be limited to the hours of 7:00 a.m. to 7:00 p.m" Monday

4.1 Prior to submitting its first monthly Application for Payment, Contractor shall
submit to Project Manager, for their review and approval, a schedule of values based
upon the Contract Price, listing the major elements of the Work and the dollar value for
each element. After its approval by the Project Manager, this schedule of values shall
be used as the basis for the Contractor's monthly Applications for Payment. This
schedule shall be updated and submitted each month along with a completed copy of
the Application for Payment form signed by the Contractor's authorized representative
and attached to the Agreernent as Exhibit D.
4,2 Prior to submitting its first monthly Application for Payment, Contractor shall

modifications to the list of Subcontractors submitted with Contractor's Bid and any
subsequently identified Subcontractors are subject to Owner's prior written approval.
The first Application for Payment shall be submitted no earlier than thirty (30) days after
the Commencement Date. Notwithstanding anything herein to the contrary, if approved
by Owner in its sole discretion, Contractor may submit its invoice for any required
Payment and Performance Bonds prior to the first Application of Payment provided that

4.3 Unless expressly approved by Owner in advance and in writing, said approval at
Owner's sole discretion, Owner is not required to make any payment for materials or
equipment that have not been incorporated into the Project. If payment is requested on
the basis of materials and equipment not incorporated into the Project, but delivered
and suitably stored at the site or at another location, and such payment and storage
have been agreed to by Owner in writing, the Application for Payment also shall be
accompanied by a bill of sale, invoice or other documentation warranting that the Owner
has received the materials and equipment free and clear of all liens, charges, security
interests and encumbrances, together with evidence that the materials and equipment
are covered by appropriate property insurance and other arrangements to protect
Owner's interest therein, all of which shall be subject to the Owner's satisfaction.
Thereafter, with each Application for Payment, Contractor also shall complete and
submit to Owner as part of its Application for Payment, the Stored Materials Record
attached hereto and made a part hereof as Exhibit 0-3.
4.4 Contractor shall submit four (4) copies of its monthly Application for Payment to
the Project Manager or his or her designee, as directed by Owner (which designee may
include the Design Professional). After the date of each Application for Payment is
stamped as received and within the timeframes set forth in Section 218.735 F.S., the
Project Manager, or Design Professional, shall either: (1) Indicate its approval of the
requested payment; (2) indicate its approval of only a portion of the requested payment,
stating in writing its reasons therefore; or (3) return the Application for Payment to the
Contractor indicating, in writing, the reason for refusing to approve payment. Payments
of proper invoices in the amounts approved shall be processed and paid in accordance
with Section 218,735, F.S. and the administrative procedures established by the
County's Purchasing Department and the Clerk of Court's Finance Department
respectively.
In the event of a total denial by Owner and return of the Application for Payment by the
Project Manager, the Contractor may make the necessary corrections and re-submit the
Application for Payment. The Owner shall, within ten (10) business days after the
Application for Payment is stamped and received and after Project Manager approval of
an Application for Payment, pay the Contractor the amounts so approved.
4.5 Owner shall retain ten percent (10%) of the gross amount of each monthly
payment request or ten percent (10%) of the portion thereof approved by the Project
Manager for payment, whichever is less. Such sum shall be accumulated and not
released to Contractor until final payment is due unless otherwise agreed to by the
Owner in accordance with Florida Statute 255.078. The Project Manager shall have the
discretion to establish, in writing, a schedule to periodically reduce the percentage of
cumulative retainage held through out the course of the Project schedule. Owner shall
reduce the amount of the retainage withheld on each payment request subsequent to
fifty percent (50%) completion subject to the guidelines set forth in Florida Statute
255.078 and as set forth in the Owner's Purchasing Policy.
4.6 Monthly payments to Contractor shall in no way imply approval or acceptance of
Contractor's Work.
GC.CA-J-4
IDA {~
4.7 Each Application for Payment, subsequent to the first pay application, shall be
accompanied by a Release and Affidavit, in the form attached as Exhibit C,
acknowledging Contractor's receipt of payment in full for all materials, labor, equipment
and other bills that are then due and payable by Owner with respect to the current
Application for Payment. Further, to the extent directed by Owner and in Owner's sole
discretion, Contractor shall also submit a Release and Affidavit from each
Subcontractor, sub-subcontractor, or supplier in the form attached as Exhibit C
acknowledging that each Subcontractor, sub-subcontractor or supplier has been paid in
full through the previous month's Application for Payment. The Owner shall not be
required to make payment until and unless these affidavits are furnished by Contractor.
4.8 Contractor agrees and understands that funding limitations exist and that the
expenditure of funds must be spread over the duration of the Project at regular intervals
based on the Contract Amount and Progress Schedule. Accordingly, prior to submitting
its first monthly Application for Payment, Contractor shall prepare and submit for Project
Manager's review and approval, a detailed Project Funding Schedule, which shall be
updated as necessary and approved by Owner to reflect approved adjustments to the
Contract Amount and Contract Time. No voluntary acceleration or early completion of
the Work shall modify the time of payments to Contractor as set forth in the approved
Project Funding Schedule.
4.9 Notwithstanding anything in the Contract Documents to the contrary, Contractor
acknowledges and agrees that in the event of a dispute concerning payments for Work
performed under this Agreement, Contractor shall continue to perform the Work
required of it under this Agreement pending resolution of the dispute provided that
Owner continues to pay Contractor all amounts that Owner does not dispute are due
and payable.
4.10 Payments will be made for services furnished, delivered, and accepted, upon
receipt and approval of invoices submitted on the date of services or within six (6)
months after completion of contract. Any untimely submission of invoices beyond the
specified deadline period is subject to non-payment under the legal doctrine of "laches"
as untimely submitted. Time shall be deemed of the essence with respect to the timely
submission of invoices under this agreement.
5. PAYMENTS WITHHELD.
5.1 The Project Manager may decline to approve any Application for Payment, or
portions thereof, because of subsequently discovered evidence or subsequent
inspections that reveal non-compliance with the Contract Documents. The Project
Manager may nullify the whole or any part of any approval for payment previously
issued and Owner may withhold any payments otherwise due Contractor under this
Agreement or any other agreement between Owner and Contractor, to such extent as
may be necessary in the Owner's opinion to protect it from loss because of;
(a) defective Work not remedied; (b) third party claims filed or reasonable evidence
indicating probable filing of such claims; (c) failure of Contractor to make payment
GC.CA-J-5
IDA &:1
properly to subcontractors or for labor, materials or equipment; (d) reasonable doubt
that the Work can be completed for the unpaid balance of the Contract Amount; (e)
reasonable indication that the Work will not be completed within the Contract Time; (f)
unsatisfactory prosecution of the Work by the Contractor; or (g) any other material
breach of the Contract Documents by Contractor.
5.2 If any conditions described in 5.1. are not remedied or removed, Owner may,
after three (3) days written notice, rectify the same at Contractor's expense. Provided,
however, in the event of an emergency, Owner shall not be required to provide
Contractor any written notice prior to rectifying the situation at Contractor's expense.
Owner also may offset against any sums due Contractor the amount of any liquidated or
non-liquidated obligations of Contractor to Owner, whether relating to or arising out of
this Agreement or any other agreement between Contractor and Owner.
6. FINAL PAYMENT.
6.1 Owner shall make final payment to Contractor in accordance with Section
218.735, F.S. and the administrative procedures established by the County's
Purchasing Department and the Clerk of Court's Finance Department after the Work is
finally inspected and accepted by Project Manager as set forth with Section 20.1 herein,
provided that Contractor first, and as an explicit condition precedent to the accrual of
Contractor's right to final payment, shall have furnished Owner with a properly executed
and notarized copy of the Release and Affidavit attached as Exhibit C, as well as, a duly
executed copy of the Surety's consent to final payment and such other documentation
that may be required by the Contract Documents and the Owner. Prior to release of
final payment and final retainage, the Contractor's Representative and the Project
Manager shall jointly complete the Final Payment Checklist, a representative copy of
which is attached to this Agreement as Exhibit G.
6.2 Contractor's acceptance of final payment shall constitute a full waiver of any and
all claims by Contractor against Owner arising out of this Agreement or otherwise
relating to the Project, except those previously made in writing in accordance with the
requirements of the Contract Documents and identified by Contractor as unsettled in its
final Application for Payment. Neither the acceptance of the Work nor payment by
Owner shall be deemed to be a waiver of Owner's right to enforce any obligations of
Contractor hereunder or to the recovery of damages for defective Work not discovered
by the Design Professional or Project Manager at the time of final inspection.
7. SUBMITTALS AND SUBSTITUTIONS.
7.1 Contractor shall carefully examine the Contract Documents for all requirements
for approval of materials to be submitted such as shop drawings, data, test results,
schedules and samples. Contractor shall submit all such materials at its own expense
and in such form as required by the Contract Documents in sufficient time to prevent
any delay in the delivery of such materials and the installation thereof.
GC-CA-J-6
IDA <\1
7.2 Whenever materials or equipment are specified or described in the Contract
Documents by using the name of a proprietary item or the name of a particular supplier,
the naming of the item is intended to establish the type, function and quality required.
Unless the name is followed by words indicating that no substitution is permitted,
materials or equipment of other suppliers may be accepted by Owner if sufficient
information is submitted by Contractor to allow the Owner to determine that the material
or equipment proposed is equivalent or equal to that named. Requests for review of
substitute items of material and equipment will not be accepted by Owner from anyone
other than Contractor and all such requests must be submitted by Contractor to Project
Manager within thirty (30) calendar days after Notice of Award is received by
Contractor, unless otherwise mutually agreed in writing by Owner and Contractor.
7.3 If Contractor wishes to furnish or use a substitute item of material or equipment,
Contractor shall make application to the Project Manager for acceptance thereof,
certifying that the proposed substitute shall adequately perform the functions and
achieve the results called for by the general design, be similar and of equal substance
to that specified and be suited to the same use as that specified. The application shall
state that the evaluation and acceptance of the proposed substitute will not prejudice
Contractor's achievement of substantial completion on time, whether or not acceptance
of the substitute for use in the Work will require a change in any of the Contract
Documents (or in the provisions of any other direct contract with Owner for the Project)
to adapt the design to the proposed substitute and whether or not incorporation or use
by the substitute in connection with the Work is subject to payment of any license fee or
royalty. All variations of the proposed substitute from that specified will be identified in
the application and available maintenance, repair and replacement service shall be
indicated. The application also shall contain an itemized estimate of all costs that will
result directly or indirectly from acceptance of such substitute, including costs for
redesign and claims of other contractors affected by the resulting change, all of which
shall be considered by the Project Manager in evaluating the proposed substitute. The
Project Manager may require Contractor to furnish at Contractor's expense additional
data about the proposed substitute.
7.4 If a specific means, method, technique, sequence or procedure of construction is
indicated in or required by the Contract Documents, Contractor may furnish or utilize a
substitute means, method, sequence, technique or procedure of construction
acceptable to the Project Manager, if Contractor submits sufficient information to allow
the Project Manager to determine that the substitute proposed is equivalent to that
indicated or required by the Contract Documents. The procedures for submission to
and review by the Project Manager shall be the same as those provided herein for
substitute materials and equipment.
7.5 The Project Manager shall be allowed a reasonable time within which to evaluate
each proposed substitute and, if need be, to consult with the Design Professional. No
substitute will be ordered, installed or utilized without the Project Manager's prior written
acceptance which shall be evidenced by a Change Order, a Work Directive Change, a
Field Order or an approved Shop Drawing. The Owner may require Contractor to
furnish at Contractor's expense a special performance guarantee or other surety with
GC-CA-J-7
lOA
respect to any substitute. The Project Manager will record time required by the Project
Manager and the Project Manager's consultants in evaluating substitutions proposed by
Contractor and making changes in the Contract Documents occasioned thereby.
Whether or not the Owner accepts a proposed substitute, Contractor shall reimburse
Owner for the charges of the Design Professional and the Design Professional's
consultants for evaluating each proposed substitute.
8. DAILY REPORTS, AS-BUlL TS AND MEETINGS.
8.1 Unless waived in writing by Owner, Contractor shall complete and submit to
Project Manager on a weekly basis a daily log of the Contractor's work for the preceding
week in a format approved by the Project Manager. The daily log shall document all
activities of Contractor at the Project site including, but not limited to, the following:
8.1.1 Weather conditions showing the high and low temperatures during
work hours, the amount of precipitation received on the Project site, and any other
weather conditions which adversely affect the Work;
8.1.2
Soil conditions which adversely affect the Work;
The hours of operation by Contractor's and Sub-Contractor's
8.1.3
personnel;
8.1.4 The number of Contractor's and Sub-Contractor's personnel present
and working at the Project site, by subcontract and trade;
8.1.5 All equipment present at the Project site, description of equipment use
and designation of time equipment was used (specifically indicating any down time);
8.1.6 Description of Work being performed at the Project site;
8.1.7 Any unusual or special occurrences at the Project site;
8.1.8 Materials received at the Project site;
8.1.9 A list of all visitors to the Project
8.1.10 Any problems that might impact either the cost or quality of the Work or
the time of performance.
The daily log shall not constitute nor take the place of any notice required to be given by
Contractor to Owner pursuant to the Contract Documents.
8.2 Contractor shall maintain in a safe place at the Project site one record copy of
the Contract Documents, including, but not limited to, all drawings, specifications,
addenda, amendments, Change Orders, Work Directive Changes and Field Orders, as
well as all written interpretations and clarifications issued by the Design Professional, in
good order and annotated to show all changes made during construction. The
GC-CA-J-8
IDA ;~
annotated drawings shall be continuously updated by the Contractor throughout the
prosecution of the Work to accurately reflect all field changes that are made to adapt the
Work to field conditions, changes resulting from Change Orders, Work Directive
Changes and Field Orders, and all concealed and buried installations of piping, conduit
and utility services. All buried and concealed items, both inside and outside the Project
site, shall be accurately located on the annotated drawings as to depth and in
relationship to not less than two (2) permanent features (e.g. interior or exterior wall
faces). The annotated drawings shall be clean and all changes, corrections and
dimensions shall be given in a neat and legible manner in a contrasting color. The
"As-Built" record documents, together with all approved samples and a counterpart of all
approved shop drawings shall be available to the Project Manager or Design
Professional for reference. Upon completion of the Work and as a condition precedent
to Contractor's entitlement to final payment, these "As-Built" record documents, samples
and shop drawings shall be delivered to Project Manager by Contractor for Owner.
8.3 Contractor shall keep all records and supporting documentation which concern or
relate to the Work hereunder for a minimum of five (5) years from the date of
termination of this Agreement or the date the Project is completed or such longer period
as may be required by law, whichever is later. Owner, or any duly authorized agents or
representatives of Owner, shall have the right to audit, inspect and copy all such
records and documentation as often as they deem necessary during the period of this
Agreement and during the document retention period noted above; provided, however,
such activity shall be conducted only during normal business hours.
9. CONTRACT TIME AND TIME EXTENSIONS.
9.1 Contractor shall diligently pursue the completion of the Work and coordinate the
Work being done on the Project by its subcontractors and material-men, as well as
coordinating its Work with all work of others at the Project Site, so that its Work or the
work of others shall not be delayed or impaired by any act or omission by Contractor.
Contractor shall be solely responsible for all construction means, methods, techniques,
sequences, and procedures, as well as coordination of all portions of the Work under
the Contract Documents, and the coordination of Owner's suppliers and contractors as
set forth in Paragraph 12.2. herein.
9.2 Should Contractor be obstructed or delayed in the prosecution of or completion
of the Work as a result of unforeseeable causes beyond the control of Contractor, and
not due to its fault or neglect, including but not restricted to acts of Nature or of the
public enemy, acts of government, fires, floods, epidemics, quarantine regulation,
strikes or lockouts, Contractor shall notify the Owner in writing within forty-eight (48)
hours after the commencement of such delay, stating the cause or causes thereof, or be
deemed to have waived any right which Contractor may have had to request a time
extension.
9.3 No interruption, interference, inefficiency, suspension or delay in the
commencement or progress of the Work from any cause whatever, including those for
which Owner may be responsible, in whole or in part, shall relieve Contractor of its duty
GC-CA-J-9
IDA I~
to perform or give rise to any right to damages or additional compensation from Owner.
Contractor expressly acknowledges and agrees that it shall receive no damages for
delay. Contractor's sole remedy, if any, against Owner will be the right to seek an
extension to the Contract Time; provided, however, the granting of any such time
extension shall not be a condition precedent to the aforementioned "No Damage For
Delay" provision. This paragraph shall expressly apply to claims for early completion,
as well as to claims based on late completion.
9.4 In no event shall any approval by Owner authorizing Contractor to continue
performing Work under this Agreement or any payment issued by Owner to Contractor
be deemed a waiver of any right or claim Owner may have against Contractor for delay
damages hereunder.
10. CHANGES IN THE WORK.
10.1 Owner shall have the right at any time during the progress of the Work to
increase or decrease the Work. Promptly after being notified of a change, Contractor
shall submit an itemized estimate of any cost or time increases or savings it foresees as
a result of the change. Except in an emergency endangering life or property, or as
expressly set forth herein, no addition or changes to the Work shall be made except
upon written order of Owner, and Owner shall not be liable to the Contractor for any
increased compensation without such written order. No officer, employee or agent of
Owner is authorized to direct any extra or changed work orally. Any alleged changes
must be approved by Owner in writing prior to starting such items. Owner will not be
responsible for the costs of any changes commenced without Owner's express prior
written approval. Failure to obtain such prior written approval for any changes will be
deemed: (i) a waiver of any claim by Contractor for such items and (ii) an admission by
Contractor that such items are in fact not a change but rather are part of the Work
required of Contractor hereunder.
10.2 A Change Order, in the form attached as Exhibit E to this Agreement, shall be
issued and executed promptly after an agreement is reached between Contractor and
Owner concerning the requested changes. Contractor shall promptly perform changes
authorized by duly executed Change Orders. The Contract Amount and Contract Time
shall be adjusted in the Change Order in the manner as Owner and Contractor shall
mutually agree.
10.3 If Owner and Contractor are unable to agree on a Change Order for the
requested change, Contractor shall, nevertheless, promptly perform the change as
directed by Owner in a written Work Directive Change. In that event, the Contract
Amount and Contract Time shall be adjusted as directed by Owner. If Contractor
disagrees with the Owner's adjustment determination, Contractor must make a claim
pursuant to Section 11 of these General Conditions or else be deemed to have waived
any claim on this matter it might otherwise have had.
10.4 In the event a requested change results in an increase to the Contract Amount,
the amount of the increase shall be limited to the Contractor's reasonable direct labor
GC-CA-J-10
IDA \~
and material costs and reasonable actual equipment costs as a result of the change
(including allowance for labor burden costs) plus a maximum ten percent (10%) markup
for all overhead and profit. In the event such change Work is performed by a
Subcontractor, a maximum ten percent (10%) markup for all overhead and profit for all
Subcontractors' and sub-subcontractors' direct labor and material costs and actual
equipment costs shall be permitted, with a maximum five percent (5%) markup thereon
by the Contractor for all of its overhead and profit, for a total maximum markup of fifteen
percent (15%). All compensation due Contractor and any Subcontractor or
sub-subcontractor for field and home office overhead is included in the markups noted
above. Contractor's and Sub-Contractor's bond costs associated with any change order
shall be included in the overhead and profit expenses and shall not be paid as a
separate line item. No markup shall be placed on sales tax, shipping or subcontractor
markup.
10.5 Owner shall have the right to conduct an audit of Contractor's books and records
to verify the accuracy of the Contractor's claim with respect to Contractor's costs
associated with any Change Order or Work Directive Change.
10.6 The Project Manager shall have authority to order minor changes in the Work not
involving an adjustment to the Contract Amount or an extension to the Contract Time
and not inconsistent with the intent of the Contract Documents. Such changes may be
effected by Field Order or by other written order. Such changes shall be binding on the
Contractor.
10.7 Any modifications to this Contract shall be in compliance with the County
Purchasing Policy and Administrative Procedures in effect at the time such
modifications are authorized.
11. CLAIMS AND DISPUTES.
11.1 Claim is a demand or assertion by one of the parties seeking an adjustment or
interpretation of the terms of the Contract Documents, payment of money, extension of
time or other relief with respect to the terms of the Contract Documents. The term
"Claim" also includes other disputes and matters in question between Owner and
Contractor arising out of or relating to the Contract Documents. The responsibility to
substantiate a Claim shall rest with the party making the Claim.
11.2 Claims by the Contractor shall be made in writing to the Project Manager within
forty-eight (48) hours from when the Contractor knew or should have known of the event
giving rise to such Claim or else the Contractor shall be deemed to have waived the
Claim. Written supporting data shall be submitted to the Project Manager within fifteen
(15) calendar days after the occurrence of the event, unless the Owner grants additional
time in writing, or else the Contractor shall be deemed to have waived the Claim. All
Claims shall be priced in accordance with the provisions of Subsection 10.4.
11.3 The Contractor shall proceed diligently with its performance as directed by the
Owner, regardless of any pending Claim, action, suit or administrative proceeding,
GC-CA-J-11
IDA !~
unless otherwise agreed to by the Owner in writing. Owner shall continue to make
payments in accordance with the Contract Documents during the pendency of any
Claim.
12. OTHER WORK.
12.1 Owner may perform other work related to the Project at the site by Owner's own
forces, have other work performed by utility owners or let other direct contracts. If the
fact that such other work is to be performed is not noted in the Contract Documents,
written notice thereof will be given to Contractor prior to starting any such other work. If
Contractor believes that such performance will involve additional expense to Contractor
or require additional time, Contractor shall send written notice of that fact to Owner and
Design Professional within forty-eight (48) hours of being notified of the other work. If
the Contractor fails to send the above required forty-eight (48) hour notice, the
Contractor will be deemed to have waived any rights it otherwise may have had to seek
an extension to the Contract Time or adjustment to the Contract Amount.
12.2 Contractor shall afford each utility owner and other contractor who is a party to
such a direct contract (or Owner, if Owner is performing the additional work with
Owner's employees) proper and safe access to the site and a reasonable opportunity
for the introduction and storage of materials and equipment and the execution of such
work and shall properly connect and coordinate its Work with theirs. Contractor shall do
all culling, fitting and patching of the Work that may be required to make its several
parts come together properly and integrate with such other work. Contractor shall not
endanger any work of others by cutting, excavating or otherwise altering their work and
will only cut or alter their work with the written consent of the Project Manager and the
others whose work will be affected. The duties and responsibilities of Contractor under
this paragraph are for the benefit of such utility owners and other Contractors to the
extent that there are comparable provisions for the benefit of Contractor in said direct
contracts between Owner and such utility owners and other contractors.
12.3 If any part of Contractor's Work depends for proper execution or results upon the
work of any other contractor or utility owner (or Owner), Contractor shall inspect and
promptly report to Project Manager in writing any delays, defects or deficiencies in such
work that render it unavailable or unsuitable for such proper execution and results.
Contractor's failure to report will constitute an acceptance of the other work as fit and
proper for integration with Contractor's Work.
13. INDEMNIFICATION AND INSURANCE.
13.1 To the maximum extent permitted by Florida law, Contractor shall indemnify and
hold harmless Owner and its officers and employees from any and all liabilities, claims,
damages, penalties, demands, judgments, actions, proceedings, losses or costs,
including, but not limited to, reasonable attorneys' fees and paralegals' fees, whether
resulting from any claimed breach of this Agreement by Contractor or from personal
injury, property damage, direct or consequential damages, or economic loss, to the
extent caused by the negligence, recklessness, or intentional wrongful misconduct of
GC-CA-J-12
IDA
; ,I
I' ~.
Contractor or anyone employed or utilized by the Contractor in the performance of this
Agreement.
13.2 The duty to defend under this Article 13 is independent and separate from the
duty to indemnify, and the duty to defend exists regardless of any ultimate liability of the
Contractor, Owner and any indemnified party. The duty to defend arises immediately
upon presentation of a claim by any party and written notice of such claim being
provided to Contractor. Contractor's obligation to indemnify and defend under this
Article 13 will survive the expiration or earlier termination of this Agreement until it is
determined by final judgment that an action against the Owner or an indemnified party
for the matter indemnified hereunder is fully and finally barred by the applicable statute
of limitations.
13.3 Contractor shall obtain and carry, at all times during its performance under the
Contract Documents, insurance of the types and in the amounts set forth in Exhibit B to
the Agreement. Further, the Contractor shall at all times comply with all of the terms,
conditions, requirements and obligations set forth under Exhibit B.
14. COMPLIANCE WITH LAWS.
14.1 Contractor agrees to comply, at its own expense, with all federal, state and local
laws, codes, statutes, ordinances, rules, regulations and requirements applicable to the
Project, including but not limited to those dealing with taxation, worker's compensation,
equal employment and safety (including, but not limited to, the Trench Safety Act,
Chapter 553, Florida Statutes). If Contractor observes that the Contract Documents are
at variance therewith, it shall promptly notify Project Manager in writing. To the extent
any law, rule, regulation, code, statute, or ordinance requires the inclusion of certain
terms in this Agreement in order for this Agreement to be enforceable, such terms shall
be deemed included in this Agreement. Notwithstanding anything in the Contract
Documents to the contrary, it is understood and agreed that in the event of a change in
any applicable laws, ordinances, rules or regulations subsequent to the date this
Agreement was executed that increases the Contractor's time or cost of performance of
the Work, Contractor is entitled to a Change Order for such increases, except to the
extent Contractor knew or should have known of such changes prior to the date of this
Agreement.
14.2 By executing and entering into this agreement, the Contractor is formally
acknowledging without exception or stipulation that it is fully responsible for complying
with the provisions of the Immigration Reform and Control Act of 1986 as located at 8
U.S.C. 1324, et seq. and regulations relating thereto, as either may be amended.
Failure by the Contractor to comply with the laws referenced herein shall constitute a
breach of this agreement and the County shall have the discretion to unilaterally
terminate this agreement immediately.
15. CLEANUP AND PROTECTIONS.
GC-CA-J-13
IDA
15.1 Contractor agrees to keep the Project site clean at all times of debris, rubbish
and waste materials arising out of the Work. At the completion of the Work, Contractor
shall remove all debris, rubbish and waste materials from and about the Project site, as
well as all tools, appliances, construction equipment and machinery and surplus
materials, and shall leave the Project site clean and ready for occupancy by Owner.
15.2 Any existing surface or subsurface improvements, including, but not limited to,
pavements, curbs, sidewalks, pipes, utilities, footings, structures, trees and shrubbery,
not indicated in the Contract Documents to be removed or altered, shall be protected by
Contractor from damage during the prosecution of the Work. Subject to the Section 2.3
above, any such improvements so damaged shall be restored by Contractor to the
condition equal to that existing at the time of Contractor's commencement of the Work.
16. ASSIGNMENT.
16.1 Contractor shall not assign this Agreement or any part thereof, without the prior
consent in writing of Owner. Any attempt to assign or otherwise transfer this Agreement,
or any part herein, without the Owner's consent, shall be void. If Contractor does, with
approval, assign this Agreement or any part thereof, it shall require that its assignee be
bound to it and to assume toward Contractor all of the obligations and responsibilities
that Contractor has assumed toward Owner.
17. PERMITS, LICENSES AND TAXES.
17.1 Pursuant to Section 218.80, F.S., Owner will pay for all Collier County permits
and fees, including license fees, permit fees, impact fees or inspection fees applicable
to the Work through an internal budget transfer(s). Contractor is not responsible for
paying for permits issued by Collier County, but Contractor is responsible for acquiring
all permits. Owner may require the Contractor to deliver internal budget transfer
documents to applicable Collier County agencies when the Contractor is acquiring
permits.
17.2 All permits, fees and licenses necessary for the prosecution of the Work which
are not issued by Collier County shall be acquired and paid for by the Contractor.
17.3 Contractor shall pay all sales, consumer, use and other similar taxes associated
with the Work or portions thereof, which are applicable during the performance of the
Work.
18. TERMINATION FOR DEFAULT.
18.1 Contractor shall be considered in material default of the Agreement and such
default shall be considered cause for Owner to terminate the Agreement, in whole or in
part, as further set forth in this Section, if Contractor: (1) fails to begin the Work under
the Contract Documents within the time specified herein; or (2) fails to properly and
timely perform the Work as directed by the Project Manager or as provided for in the
approved Progress Schedule; or (3) performs the Work unsuitably or neglects or
refuses to remove materials or to correct or replace such Work as may be rejected as
GC-CA-J-14
IDA

.
unacceptable or unsuitable; or (4) discontinues the prosecution of the Work; or (5) fails
to resume Work which has been suspended within a reasonable time after being
notified to do so; or (6) becomes insolvent or is declared bankrupt, or commits any act
of bankruptcy; or (7) allows any final judgment to stand against it unsatisfied for more
than ten (10) days; or (8) makes an assignment for the benefit of creditors; or (9) fails to
obey any applicable codes, laws, ordinances, rules or regulations with respect to the
Work; or (10) materially breaches any other provision of the Contract Documents.
18.2 Owner shall notify Contractor in writing of Contractor's default(s). If Owner
determines that Contractor has not remedied and cured the default(s) within seven (7)
calendar days following receipt by Contractor of said written notice or such longer
period of time as may be consented to by Owner in writing and in its sole discretion,
then Owner, at its option, without releasing or waiving its rights and remedies against
the Contractor's sureties and without prejudice to any other right or remedy it may be
entitled to hereunder or by law, may terminate Contractor's right to proceed under the
Agreement, in whole or in part, and take possession of all or any portion of the Work
and any materials, tools, equipment, and appliances of Contractor, take assignments of
any of Contractor's subcontracts and purchase orders, and complete all or any portion
of Contractor's Work by whatever means, method or agency which Owner, in its sole
discretion, may choose.
18.3 If Owner deems any of the foregoing remedies necessary, Contractor agrees that
it shall not be entitled to receive any further payments hereunder until after the Project is
completed. All moneys expended and all of the costs, losses, damages and extra
expenses, including all management, administrative and other overhead and other
direct and indirect expenses (including Design Professional and attorneys' fees) or
damages incurred by Owner incident to such completion, shall be deducted from the
Contract Amount, and if such expenditures exceed the unpaid balance of the Contract
Amount, Contractor agrees to pay promptly to Owner on demand the full amount of
such excess, including costs of collection, attorneys' fees (including appeals) and
interest thereon at the maximum legal rate of interest until paid. If the unpaid balance of
the Contract Amount exceeds all such costs, expenditures and damages incurred by the
Owner to complete the Work, such excess shall be paid to the Contractor. The amount
to be paid to the Contractor or Owner, as the case may be, shall be approved by the
Project Manager, upon application, and this obligation for payment shall survive
termination of the Agreement.
18.4 The liability of Contractor hereunder shall extend to and include the full amount of
any and all sums paid, expenses and losses incurred, damages sustained, and
obligations assumed by Owner in good faith under the belief that such payments or
assumptions were necessary or required, in completing the Work and providing labor,
materials, equipment, supplies, and other items therefor or re-Ietting the Work, and in
settlement, discharge or compromise of any claims, demands, suits, and judgments
pertaining to or arising out of the Work hereunder.
18.5 If, after notice of termination of Contractor's right to proceed pursuant to this
Section, it is determined for any reason that Contractor was not in default, or that its
GC-CA-J-15
IDA
default was excusable, or that Owner is not entitled to the remedies against Contractor
provided herein, then the termination will be deemed a termination for convenience and
Contractor's remedies against Owner shall be the same as and limited to those afforded
Contractor under Section 19 below.
18.6 In the event (i) Owner fails to make any undisputed payment to Contractor within
thirty (30) days after such payment is due or Owner otherwise persistently fails to fulfill
some material obligation owed by Owner to Contractor under this Agreement, and
(ii) Owner has failed to cure such default within fourteen (14) days of receiving written
notice of same from Contractor, then Contractor may stop its performance under this
Agreement until such default is cured, after giving Owner a second fourteen (14) days
written notice of Contractor's intention to stop performance under the Agreement. If the
Work is so stopped for a period of one hundred and twenty (120) consecutive days
through no act or fault of the Contractor or its Subcontractors or their agents or
employees or any other persons performing portions of the Work under contract with the
Contractor or any Subcontractor, the Contractor may terminate this Agreement by giving
written notice to Owner of Contractor's intent to terminate this Agreement. If Owner
does not cure its default within fourteen (14) days after receipt of Contractor's written
notice, Contractor may, upon fourteen (14) additional days' written notice to the Owner,
terminate the Agreement and recover from the Owner payment for Work performed
through the tenmination date, but in no event shall Contractor be entitled to payment for
Work not performed or any other damages from Owner.
19. TERMINATION FOR CONVENIENCE AND RIGHT OF SUSPENSION.
19.1 Owner shall have the right to terminate this Agreement without cause upon
seven (7) calendar days written notice to Contractor. In the event of such termination
for convenience, Contractor's recovery against Owner shall be limited to that portion of
the Contract Amount earned through the date of termination, together with any
retainage withheld and reasonable termination expenses incurred, but Contractor shall
not be entitled to any other or further recovery against Owner, including, but not limited
to, damages or any anticipated profit on portions of the Work not performed.
19.2 Owner shall have the right to suspend all or any portions of the Work upon giving
Contractor not less than two (2) calendar days' prior written notice of such suspension.
If all or any portion of the Work is so suspended, Contractor's sole and exclusive
remedy shall be to seek an extension of time to its schedule in accordance with the
procedures set forth in the Contract Documents. In no event shall the Contractor be
entitled to any additional compensation or damages. Provided, however, if the ordered
suspension exceeds six (6) months, the Contractor shall have the right to terminate the
Agreement with respect to that portion of the Work which is subject to the ordered
suspension.
20. COMPLETION.
20.1 When the entire Work (or any portion thereof designated in writing by Owner) is
ready for its intended use, Contractor shall notify Project Manager in writing that the
GC-CA-J-16
IDA
entire Work (or such designated portion) is substantially complete. Within a reasonable
time thereafter, Owner, Contractor and Design Professional shall make an inspection of
the Work (or designated portion thereof) to determine the status of completion. If
Owner, after conferring with the Design Professional, does not consider the Work (or
designated portion) substantially complete, Project Manager shall notify Contractor in
writing giving the reasons therefor. If Owner, after conferring with the Design
Professional, considers the Work (or designated portion) substantially complete, Project
Manager shall prepare and deliver to Contractor a Certificate of Substantial Completion
which shall fix the date of Substantial Completion for the entire Work (or designated
portion thereof) and include a tentative punch-list of items to be completed or corrected
by Contractor before final payment. Owner shall have the right to exclude Contractor
from the Work and Project site (or designated portion thereof) after the date of
Substantial Completion, but Owner shall allow Contractor reasonable access to
complete or correct items on the tentative punch-list.
20.2 Upon receipt of written certification by Contractor that the Work is completed in
accordance with the Contract Documents and is ready for final inspection and
acceptance, Project Manager and Design Professional will make such inspection and, if
they find the Work acceptable and fully performed under the Contract Documents shall
promptly issue a final Certificate for Payment, recommending that, on the basis of their
observations and inspections, and the Contractor's certification that the Work has been
completed in accordance with the terms and conditions of the Contract Documents, that
the entire balance found to be due Contractor is due and payable. Neither the final
payment nor the retainage shall become due and payable until Contractor submits:
(1) Receipt of Contractor's Final Application for Payment.
(2) The Release and Affidavit in the form attached as Exhibit C.
(3) Consent of surety to final payment.
(4) Receipt of the final payment check list.
(5) If required by Owner, other data establishing payment or satisfaction of all
obligations, such as receipts, releases and waivers of liens, arising out of
the Contract Documents, to the extent and in such form as may be
designated by Owner.
Owner reserves the right to inspect the Work and make an independent determination
as to the Work's acceptability, even though the Design Professional may have issued its
recommendations. Unless and until the Owner is completely satisfied, neither the final
payment nor the retainage shall become due and payable.
21. WARRANTY.
21.1 Contractor shall obtain and assign to Owner all express warranties given to
Contractor or any subcontractors by any subcontractor or materialmen supplying
materials, equipment or fixtures to be incorporated into the Project. Contractor warrants
to Owner that any materials and equipment furnished under the Contract Documents
shall be new unless otherwise specified, and that all Work shall be of good quality, free
from all defects and in conformance with the Contract Documents. Contractor further
GC-CA-J-17
10 A'f
warrants to Owner that all materials and equipment furnished under the Contract
Documents shall be applied, installed, connected, erected, used, cleaned and
conditioned in accordance with the instructions of the applicable manufacturers,
fabricators, suppliers or processors except as otherwise provided for in the Contract
Documents. If, within one (1) year after Substantial Completion, any Work is found to
be defective or not in conformance with the Contract Documents, Contractor shall
correct it promptly after receipt of written notice from Owner. Contractor shall also be
responsible for and pay for replacement or repair of adjacent materials or Work which
may be damaged as a result of such replacement or repair. Further, in the event of an
emergency, Owner may commence to correct any defective Work, without prior notice
to Contractor, at Contractor's expense. These warranties are in addition to those
implied warranties to which Owner is entitled as a matter of law.
21.2 No later than 30 days prior to expiration of the warranty, the Project Manager, or
another representative of the Owner, shall conduct an inspection of the warranted work
to verify compliance with the requirements of the Agreement. The Contractor's
Representative shall be present at the time of inspection and shall take remedial actions
to correct any deficiencies noted in the inspection. Failure of the Contractor to correct
the cited deficiencies shall be grounds for the Owner to disqualify the Contractor from
future bid opportunities with the Owner, in addition to any other rights and remedies
available to Owner.
22. TESTS AND INSPECTIONS.
22.1 Owner, Design Professional, their respective representatives, agents and
employees, and governmental agencies with jurisdiction over the Project shall have
access at all times to the Work, whether the Work is being performed on or off of the
Project site, for their observation, inspection and testing. Contractor shall provide
proper, safe conditions for such access. Contractor shall provide Project Manager with
timely notice of readiness of the Work for all required inspections, tests or approvals.
22.2 If the Contract Documents or any codes, laws, ordinances, rules or regulations of
any public authority having jurisdiction over the Project requires any portion of the Work
to be specifically inspected, tested or approved, Contractor shall assume full
responsibility therefore, pay all costs in connection therewith and furnish Project
Manager the required certificates of inspection, testing or approval. All inspections,
tests or approvals shall be performed in a manner and by organizations acceptable to
the Project Manager.
22.3 Contractor is responsible, without reimbursement from Owner, for re-inspection
fees and costs; to the extent such re-inspections are due to the fault or neglect of
Contractor.
22.4 If any Work that is to be inspected, tested or approved is covered without written
concurrence from the Project Manager, such work must, if requested by Project
Manager, be uncovered for observation. Such uncovering shall be at Contractor's
expense unless Contractor has given Project Manager timely notice of Contractor's
GC-CA-J-18
IDA
intention to cover the same and Project Manager has not acted with reasonable
promptness to respond to such notice. If any Work is covered contrary to written
directions from Project Manager, such Work must, if requested by Project Manager, be
uncovered for Project Manager's observation and be replaced at Contractor's sole
expense.
22.5 The Owner shall charge to Contractor and may deduct from any payments due
Contractor all engineering and inspection expenses incurred by Owner in connection
with any overtime work. Such overtime work consisting of any work during the
construction period beyond the regular eight (8) hour day and for any work performed
on Saturday, Sunday or holidays.
22.6 Neither observations nor other actions by the Project Manager or Design
Professional nor inspections, tests or approvals by others shall relieve Contractor from
Contractor's obligations to perform the Work in accordance with the Contract
Documents.
23. DEFECTIVE WORK.
23.1 Work not conforming to the requirements of the Contract Documents or any
warranties made or assigned by Contractor to Owner shall be deemed defective Work.
If required by Project Manager, Contractor shall as directed, either correct all defective
Work, whether or not fabricated, installed or completed, or if the defective Work has
been rejected by Project Manager, remove it from the site and replace it with non-
defective Work. Contractor shall bear all direct, indirect and consequential costs of
such correction or removal (including, but not limited to fees and charges of engineers,
architects, attorneys and other professionals) made necessary thereby, and shall hold
Owner harmless for same.
23.2 If the Project Manager considers it necessary or advisable that covered Work be
observed by Design Professional or inspected or tested by others and such Work is not
otherwise required to be inspected or tested, Contractor, at Project Manager's request,
shall uncover, expose or otherwise make available for observation, inspection or tests
as Project Manager may require, that portion of the Work in question, furnishing all
necessary labor, material and equipment. If it is found that such Work is defective,
Contractor shall bear all direct, indirect and consequential costs of such uncovering,
exposure, observation, inspection and testing and of satisfactory reconstruction
(including, but not limited to, fees and charges of engineers, architects, attorneys and
other professionals), and Owner shall be entitled to an appropriate decrease in the
Contract Amount. If, however, such Work is not found to be defective, Contractor shall
be allowed an increase in the Contract Amount and/or an extension to the Contract
Time, directly attributable to such uncovering, exposure, observation, inspection, testing
and reconstruction.
23.3 If any portion of the Work is defective, or if Contractor fails to supply sufficient
skilled workers, suitable materials or equipment or fails to finish or perform the Work in
such a way that the completed Work will conform to the Contract Documents, Project
GC-CA-J-19
IDA
'.
~.~
Manager may order Contractor to stop the Work, or any portion thereof, until the cause
for such order has been eliminated. The right of Project Manager to stop the Work
shall be exercised, if at all, solely for Owner's benefit and nothing herein shall be
construed as obligating the Project Manager to exercise this right for the benefit of
Design Engineer, Contractor, or any other person.
23.4 Should the Owner determine, at its sole opinion, it is in the Owner's best interest
to accept defective Work, the Owner may do so. Contractor shall bear all direct, indirect
and consequential costs attributable to the Owner's evaluation of and determination to
accept defective Work. If such determination is rendered prior to final payment, a
Change Order shall be executed evidencing such acceptance of such defective Work,
incorporating the necessary revisions in the Contract Documents and reflecting an
appropriate decrease in the Contract Amount. If the Owner accepts such defective
Work after final payment, Contractor shall promptly pay Owner an appropriate amount
to adequately compensate Owner for its acceptance of the defective Work.
23.5 If Contractor fails, within a reasonable time after the written notice from Project
Manager, to correct defective Work or to remove and replace rejected defective Work
as required by Project Manager or Owner, or if Contractor fails to perform the Work in
accordance with the Contract Documents, or if Contractor fails to comply with any of the
provisions of the Contract Documents, Owner may, after seven (7) days written notice
to Contractor, correct and remedy any such deficiency. Provided, however, Owner shall
not be required to give notice to Contractor in the event of an emergency. To the extent
necessary to complete corrective and remedial action, Owner may exclude Contractor
from any or all of the Project site, take possession of all or any part of the Work, and
suspend Contractor's services related thereto, take possession of Contractor's tools,
appliances, construction equipment and machinery at the Project site and incorporate in
the Work all materials and equipment stored at the Project site or for which Owner has
paid Contractor but which are stored elsewhere. Contractor shall allow Owner, Design
Professional and their respective representatives, agents, and employees such access
to the Project site as may be necessary to enable Owner to exercise the rights and
remedies under this paragraph. All direct, indirect and consequential costs of Owner in
exercising such rights and remedies shall be charged against Contractor, and a Change
Order shall be issued, incorporating the necessary revisions to the Contract Documents,
including an appropriate decrease to the Contract Amount. Such direct, indirect and
consequential costs shall include, but not be limited to, fees and charges of engineers,
architects, attorneys and other professionals, all court costs and all costs of repair and
replacement of work of others destroyed or damaged by correction, removal or
replacement of Contractor's defective Work. Contractor shall not be allowed an
extension of the Contract Time because of any delay in performance of the Work
attributable to the exercise by Owner of Owner's rights and remedies hereunder.
24. SUPERVISION AND SUPERINTENDENTS.
24.1 Contractor shall plan, organize, supervise, schedule, monitor, direct and control
the Work competently and efficiently, devoting such attention thereto and applying such

Contract Documents. Contractor shall be responsible to see that the finished Work
complies accurately with the Contract Documents. Contractor shall keep on the Work at
all times during its progress a competent resident superintendent, who shall be subject
to Owner's approval and not be replaced without prior written notice to Project Manager

the Contractor and be the Contractor's representative at the Project site and shall have
authority to act on behalf of Contractor. All communications given to the superintendent
shall be as binding as if given to the Contractor. Owner shall have the right to direct
Contractor to remove and replace its Project superintendent, with or without cause.
Attached to the Agreement as Exhibit N is a list identifying Contractor's Project
Superintendent and all of Contractor's key personnel who are assigned to the Project;
such identified personnel shall not be removed without Owner's prior written approval,
and if so removed must be immediately replaced with a person acceptable to Owner.
24.2 Contractor shall have a competent superintendent on the project at all times
whenever contractor's work crews, or work crews of other parties authorized by the
Project Manager are engaged in any activity whatsoever associated with the Project.
Should the Contractor fail to comply with the above condition, the Project Manager
shall, at his discretion, deduct from the Contractor's monthly pay estimate, sufficient
moneys to account for the Owner's loss of adequate project supervision, not as a
penalty, but as liquidated damages, separate from the liquidated damages described in
Section 5.B, for services not rendered.
25. PROTECTION OF WORK.
25.1 Contractor shall fully protect the Work from loss or damage and shall bear the
cost of any such loss or damage until final payment has been made. If Contractor or
anyone for whom Contractor is legally liable for is responsible for any loss or damage
to the Work, or other work or materials of Owner or Owner's separate contractors,
Contractor shall be charged with the same, and any moneys necessary to replace such
loss or damage shall be deducted from any amounts due Contractor.

Professional with respect to the Project. If Contractor, or its subcontractors, agents or
anyone for whom Contractor is legally liable, disturbs the Owner or Design
Professional's benchmarks, Contractor shall immediately notify Project Manager and
Design Professional. The Owner or Design Professional shall re-establish the
benchmarks and Contractor shall be liable for all costs incurred by Owner associated
therewith.

IDA
26.1 In the event of an emergency affecting the safety or protection of persons or the
Work or property at the Project site or adjacent thereto, Contractor, without special
instruction or authorization from Owner or Design Professional is obligated to act to
prevent threatened damage, injury or loss. Contractor shall give Project Manager
written notice within forty-eight (48) hours after Contractor knew or should have known
of the occurrence of the emergency, if Contractor believes that any significant changes
in the Work or variations from the Contract Documents have been caused thereby. If
the Project Manager determines that a change in the Contract Documents is required
because of the action taken in response to an emergency, a Change Order shall be
issued to document the consequences of the changes or variations. If Contractor fails
to provide the forty-eight (48) hour written notice noted above, the Contractor shall be
deemed to have waived any right it otherwise may have had to seek an adjustment to
the Contract Amount or an extension to the Contract Time.

In order to perform the work listed above, multiple aeration basins will
need to be taken out of service for an extended period of time. The
Contractor will be required to coordinate the basin construction timing
and schedule with the Owner. In order to accommodate the air
requirements of the Aeration Basins, the construction phase steps
anticipated for this work are as follows:
a. The Contractor shall install a temporary 24" steel aeration air
bypass pipe for the air header between basins 4A and 5B. The
temporary pipe shall be laid on the deck of the aeration basins and
eventually tied into the 30"x24" SS tee and 24" SS tee installed in a
later step of this sequence.
b. The Oxidation Ditch Treatment Train will need to be placed into
operation by the Owner prior to isolation of the aeration basins. No
more than 6 aeration basins can be taken out of service at a time.
The North Bleach System improvements cannot be undertaken
during the time that the Oxidation Ditch Treatment Train is
operational.
c. Influent flow, air flow and electrical power to Aeration Basins
4A, 4B, 4C, 4D, 5A and 5B shall be interrupted.
d. Blower Building 1 blower operation will be shut down. The
shutdown of the blower building shall not exceed 3 hours. If the
shutdown is anticipated to be longer than 3 hours, the Contractor
will need to provide temporary blowers to feed process air to basins
5C, 5D, 6A, 6B, 6C and 6D. Temporary blowers will need to be
capable of supplying 7,000 scfm to the aeration basins.
f. A new 3o"x24" SS tee with blind flange (North end) will be installed in
the existing aeration header between basins 5B and 5C. A new
30"x24" SS tee with blind flange (on downstream end) will be
installed in the existing aeration header vertical riser upstream of

Section until backfilling is completed.
2.03 BEDDING MATERIALS
A. Crushed Stone Bedding: Imported, graded stone meeting the requirements of
Class I with maximum particle size equal to one-half inch (1/2").
1. Size range and resulting high void ratio of crushed stone bedding material
makes it suitable for use to dewater trenches during pipe installation.
2. The permeable characteristic of crushed stone dictates that use of crushed
stone bedding material be limited to locations where pipe support will not be
lost by migration of fine grained natural material from trench walls and
bottom or migration of other embedment materials into crushed stone
bedding material.
3. When migration of fine grained natural material into crushed stone bedding
is possible;
a. Crushed stone bedding shall be reduced to finer than one-quarter inch
(1/4") minimum, and gradation shall be selected to limit the size of the
voids, or;
b. An alternative to modifying the gradation is to use a geotextile fabric as
a barrier to migration to fines.

B. Limerock Base
1. If Iimerock base is existing, such as for paving an existing limerock road, make
thickness and density measurements on each 3,000 square feet of base. If the base
meets the requirements of this specification, it may be used in-place. If it does not
meet this specification, prepare the Iimerock base as described below.
2. Construct Iimerock base in accordance with Section 200 of the DOT Specifications,
to the thickness and width indicated on the Drawings.
3. After spreading of the base material is completed, scarify entire surface and shape
. surface to produce the exact grade and cross section after compaction. For double
course base, extend scarifying to a depth sufficient to penetrate slightly the surface
of the first course. The maximum depth of each lift shall be 8 inches.
4. When the material does not have the proper moisture content to insure the required
density, wetting or drying shall be required.
a. If the material is deficient in moisture, add and uniformly mix in water by disking
the base course to the full depth of the base course.
b. If the material contains an excess of moisture, allow the material to dry to proper
moisture content before compacting material.
5. As soon as proper conditions of moisture are attained, compact material to an
average density not less than 98 percent maximum density. If there is more than one
course, the density shall be obtained in each lift of the base.
6. During final compacting operations, if blading of any areas is necessary to obtain true
grade and cross section, complete compacting operations for such areas prior to
making density determination on finished base.
7. Unless otherwise directed by the Engineer, "hard-plane" the surface with a blade
grader immediately prior to the application of the prime coat to remove the thin glaze
or cemented surface and to allow free penetration of the prime material. Materials
planed from the base shall be removed from base area.
8. If cracks or checks appear in the base, either before or after priming, which in the
opinion of the Engineer, would impair the structural efficiency of the base course,
remove such cracks or checks by rescarifying, reshaping, adding base material
where necessary and recompacting.
9. If at any time the subgrade material shall become mixed with the base course
material, dig out and remove the mixture, reshape and compact the subgrade and
replace the materials removed with clean base material. Shape and compact clean

handling and placing. Color of cement grout shall rnatch the adjacent wall surface.
2. TYpe iI - Grout Cleaned: Where this finish is required, it shall be applied after
completion of Type I finish, After the concrete has been predampened, a slurry
consisting of one part cement (including an appropriate quantity of white cement in
order to produce a color matching the surrounding concrete) and 1-1/2 parts sand
passing the No, 16 sieve, by damp loose volume, shall be spread over the surface with
clean burlap pads or sponge rubber floats. Any surplus shall be removed by scraping
and then rubbing with clean burlap. The finish shall be kept damp for at least 36 hours
after application.

intervals and striking off to the surface elevation required. When a Type "F" finish is
subsequently to be applied, the surface of the screeded concrete shall be roughened
with a stiff brush or rake prior to final set.
2. TYpe "B" - Wood Floated: This finish shall be obtained after completion of a Type "A"
finish by working a previously screeded surface with a wood float until the desired
texture is reached. Floating shall begin when the water sheen has disappeared and.
when the concrete has sufficiently hardened so that a person's foot leaves only a slight
imprint. If wet spots occur, water shall be removed with a squeegee. Care shall be
taken to prevent the formation of laitance and excess water on the finished surface.
The finished surface shall be true, even, and free from blemishes and other
irregularities.
3. IYPe "C" - Cork Floated: This finish shall be similar to Type "B" but slightly smoother
than that obtained with a wood float. It shall be obtained by power or band floating
with cork fioats.
4. IYPe "D" - Steel Troweled: This finish shall be obtained after completion of a Type "B"
finish. When the concrete has hardened sufficiently to prevent excess fine material
from working to the surface, the surface shall be compacted and smoothed with not
less than two thorough and complete steel troweling operations. In areas which are to
receive a floor covering such as tile, resilient flooring, or carpeting, only one troweling
operation is required, The finish shall be brought to a smooth, dense surface, free
from defects and blemishes,

A. The valve shall be a Model 24" 131 EG-BW BCNSYKCKO D.S. X117D as manufactured by
Cia-Val Co. Newport Beach, CA, or approved equal.
B. The flow control valve will be installed to electronically open and close slowly to control the
flow to a desired rate, as positioned by the 131VC-1 controller. This will be accomplished
through a set of solenoids in the pilot system. It will have one normally closed solenoid
energized to open feeding the cover and another normally open solenoid eXhausting the
cover. The solenoids will be controlled by use of the manufacturer's 131VC-1 controller. The
131VC-1 controller will accept a flow signal/process variable from the upstream flow meter
through the SCADA system. It will compare this flow signal with the operator supplied set
point and position the valve to the desired rate. The pilot control system will have a eRA pilot
in series to maintain a constant back pressure to keep the inlet from dropping too low. The
24" vavle will be designed to handle the 500 gpm flow from one reuse pump up to all six
reuse pumps for a total maximum flow of 18,000 gpm, at the given pressure differential.
C. The main valve will be diaphragm actuated and consist of three components; the body,
cover and diaphragm assembly. It will be ductile iron and have Type 316 stainless steel anti-
cavitation trim. The trim will consist of a stationary seat with radial slots to break the pressure
as it enters the valve. The other component is the disc guide. It has angular radial slots to
break the pressure as it exits the valve seat area. The solenoids, tubing and fittings will also
be of stainless steel. The cover will have a locating lip for ease of maintenance. There shall
be no pinned covers for alignment. All ferrous metal surfaces will have an NSF approved
fusion bonded epoxy coating. The diaphragm assembly shall be fully guided by a bearing in
the seat and a bearing in the valve cover. The main valve will have a single diaphragm,
which separates line pressure from the operating chamber in the cover. The valve ends shall
have 150 Ib flanges.

D. The pilot system will consist of two solenoids, one for opening and one for closing. They will
be actuated by the manufacturer's 131VC-1 electronic controller. The 131VC-1 controller is
120vac and will be set to slowly open and close to position the main valve. It will accept
either a remote 4-20ma signal or a digital dry contact closure to open or close the valve from
the SCADA system. It will compare this set point signal to the flow rate, as indicated by the
meter and open or close the main valve until the set point equals the flow readout. The valve
position signal will be monitored by a X117D valve position indicator. In the case of a power
outage, the valve closing solenoid will open and the opening solenoid will close. This will
cause the 24" valve to go to the closed position. During normal operation the eRA pilot will
monitor inlet pressure and modulate to sustain a back pressure set point, ensuring the inlet
pressure never drops too low. The pilot system will also contain two CV flow control needle
valves designed to help ensure the valve will open and close slowly.
E. The manufacturer shall provide a hinged, JIC oil-tight, NEMA 4X Type 316 stainless steel
local control panel with interior mounting dead front and an outer door with a three point
latch. The 120 volt supply power shall be equipped with a surge suppressor, EDCO HSP 121
TVSS device. All analog signals into and outofthe panel shall be protected by EDCO signal

IDA
A. The system shall be an effective, aesthetically acceptable streamer-delaying
lightning protection system to the standards of Underwriters Laboratories UL 96 &
UL96A. The purpose ofthe system shall be to reduce the likelihood of a direct strike
to the protected structure by delaying the formation of streamers from that structure.
Secondarily the system shall be designed in such a manner that it affords protection
to the structure upon which it is installed in the event a direct lightning strike to the
structure does occur.
B. The system components shall not require mounting in a specific configuration or
impose any other mounting limitations which may interfere with utility use of structure
space or otherwise preclude or limit the intended use of the structure.
C. All components shall be attached to the structure in such a manner as to reduce the
possibility of corrosion between dissimilar metals. If installed on a metallic or
otherwise electrically conductive structure, the system shall be electrically bonded to
the structure upon which it is installed through mounting clamps and brackets, with
additional bonding to grounded objects and to the structure, as required or as
indicated on the drawings.
D. The system shall be composed of components that meet the requirements of
Underwriters Laboratories UL 96. Aluminum and Stainless Steel components shall
be employed on structures and portions of structures subject to corrosive elements,
where the use of copper components could be rendered ineffective, due to the
surrounding environment. No dissimilar metals shall be allowed to be in contact.
E. Air Terminals shall be mounted on all outside corners of each structure, around the
perimeter of each structure at intervals not to exceed twenty (20) feet, and on the
interior of each structure in such a manner that no two Air Terminals are separated
by a distance of more than fifty (50) feet. In the event this is not practical, such as on
a large open tank, Air Terminal spacing around the perimeter shall be decreased to
not more than fifteen (15) feet, with a total number around the perimeter not less
than the total of the normally required perimeter Air Terminals, plus the additional
number of Air Terminals if Air Terminals had been installed on the interior at intervals
not greater than fifty (50) feet.
F. Each Air Terminal shall be provided with two (2) contiguous paths to ground. On
structures with handrails, exposed structural members, or other conductors, provide
a bond to structural conductors from the lightning protection system. Handrails shall
not be used as a main lightning protection conductor. Provide a continuous lightning
protection conductor parallel with handrails and bond from it to each handrail section
and a minimum of 10' on center. In the case of a structure or a portion of the
structure where the structure itself is electrically conductive, such as a light pole,
tower, etc, that structure or portion of the structure itself may be employed as part of
the lightning protection system, provided it meets the minimum requirements of UL
96 or UL 96A, and down conductors are specifically not required on such structures.

characteristics:
1. With the exception of LDFW 3, all LDFW modules sequence the operation of
equipment units by outputting discrete values to an associated MINT module.
2. All LDFW modules shall sequence the operation of equipment units to equalize the
elapsed running times of each unit from the time of original startup or a major
overhaul (when the user resets the run time to zero). Provision shall be made for
both automatic, semi-automatic and manual sequence selection. Automatic
sequence selection shall involve the addition of an available equipment unit with the
least run time when another must be started and the removal of the unit with the
most run time when a unit must be stopped. Automatic sequence selection shall be
inhibited by the manual entry of a desired sequence. Provision shall also be made to
semi-automatically reorder the manually entered lead/follow sequence every "X"

V. LDFW1-Lead/Follow Sequence Control ([ype 1) - This function is used to control the
starting, stopping and sequencing of two or more pumps operating into a pressure system.
LDFW1 starts a pump whenever the discharge pressure Pa drops below a user-adjustable
value Pre-set, and stops the last-started pump whenever the aggregate pumping capacity of
the running pumps less one (Fb) exceeds the actual flow (Fa) by more than a
user-adjustable percentage value, Fx i.e., when 100 * ((Fb-Fa)/Fb)GT.Fx. A time delay
between starting or stopping pumps shall be provided to stabilize the process. The point
number and the low limit value of the discharge pressure and the point number of the
discharge flow Fa will be entered at the operator workstations by the operator. In general, if
X pumps are provided, a maximum of (X-1) pumps may run simultaneously.
W. LDFW2-Lead/Follow Sequence Control (Type 2) - This function is similar to the LDFWl
function, except that the value of the speed control signal is used for starting an additional
pump in lieu of a fall in discharge pressure. When the speed control signal (Sa) raises
above the speed setpoint limit (Ss), the next pump in sequence is started. Whenever a
motor is started or stopped, the set point Ss shall be increased or decreased by a value (D)
from a table determined by the number of motors which are running in order to minimize
process bumps.
X. LDFW3-Lead/Follow Sequence Control (Type 3) - LDFW3 sequences the operation of a
series of equipment items to equalize the running times that have elapsed since each was
originally placed in service or given a complete overhaul. LDFW3 does not control the
starting or stopping of equipment. These functions are performed as described in the
associated control strategy.
Y. LDFW4-Lead/Follow Sequence Control (Type 4) - This function is used to control the
starting, stopping and sequencing of two or more pumps operating in conjunction with a level
control system. LDFW4 starts the lead pump whenever the level increases above a pre-set
value L 1, and the first follow pump when the level increases above L2 and so on with the
(x-1 )the follow pump being started when the level increases to Lx-l. If specified in the
associated control strategy, an additional starting requirement for a follow pump is that the
previously-started pump in the sequence is running at maximum output.
LDFW4 stops the pumps in the reverse order with the last started pump being stopped when
the level drops below a pre-set value L(x-l )d, the next to the last one at L(x-2)d, and so on,
until the lead pump is stopped. The pump start and stop levels and pump sequence for
each control strategy are entered via the operator workstations.
Z. LDFW5-Lead/Follow Sequence Control (Type 5) - LDFW5 is used to start, stop and
sequence two or more pumps operating in conjunction with a level and flow control system.
LDFW5 starts the lead pump whenever the level increases above a pre-set value L 1, the
first follow pump when the level increases above L2 and so on until the (x-1) the follow pump
is started when the level exceeds L(x-1).
LDFW5 stops the pumps in any nominated order based on either level signals or flow
signals; i.e" a nominated pump can be shut off when either the level in the sump or the
aggregate pump output flow falls to an adjustable, pre-set value. The pump start levels, stop
levels, or flow values and the pump sequence is entered at the workstations.

X and Y = input values
AC. MAXMIN-Maximum/Minimum Identification - The MAXIMUM module shall record the
maximum and minimum data value generated by measured and virtual variables during a
designated time interval. Two maximum/minimum identification detection modes shall be
provided. The first shall consist of monitoring discrete data values which are sequentially
compared against the previously detected discrete maximum and minimum values. The
second mode shall consist of averaging the three most current data values and then
comparing the average against both existing maximum and minimum averaged values. The
second mode is provided to reduce the effects of random noise. For both modes, previously
detected maximum and minimum values shall be replaced whenever exceeded by current
high and low data values, respectively. The time of maximum and minimum value
occurrences shall be recorded.
AD. MINT-Motor Interface - MINT shall control the automatic and manual operation of equipment
with the following combinations of discrete interface points.
1. Ready, running, start/stop
2. Closed, opened, ready, open, close
3. Running (high speed or forward), running (low speed or reverse), ready, start (high
speed or forward), start (low speed or reverse), and stop.
Outputs shall be maintained or momentary as required by the electrical elementary
diagrams.
Operation shall be based upon an internal delay timer, ready alarm status and a discrepancy
alarm status.

MINT shall first check the equipment ready status. If the ready status is not present, MINT
shall enter a ready alarm state and the equipment shall be stopped by the associated control
strategy (or control module). Upon recovery of ready status, the equipment will not restart
until subsequently commanded by the associated control strategy (or control module).
If the control command changes (i.e., from start to stop), the appropriate discrete output
shall be generated and a delay time loaded into a counter. During the countdown to zero,
the commanded state shall be compared with the running status. When the two agree, the
counter shall be reset and cleared.
If the counter times out before the requested state is achieved, the equipment shall enter a
discrepancy alarm and the run/start command shall be removed by the associated control
strategy and the next unit in sequence shall be started. When the requested state and run
status again agree, the discrepancy alarm shall be cleared (however, alarm event remains in
the alarm queue until acknowledged by the operator). The discrepancy alarm shall be
disabled where multiple sources of control commands would otherwise cause alarms. MINT
shall continually monitor equipment and alarm status during normal operation.
AE. MSEL-Median Selector- The MSEL module shall selectthe intermediate value of three real
time measurements of the same process variable. The intermediate value shall be
employed for recording and control purposes. If the differentials between the intermediate
value and the high and low values exceed adjustable, pre-set limits, the time and nature of
the limit violation shall be recorded.
AF. MSIM-Motor Simulation Module - The MSIM module shall be used to simulate the operation
of pumps, blowers, and other items of rotating motor driven equipment. Inputs to MSIM shall
include a desired state discrete input (D) and a "ready" state discrete input (W). A delay
time (T) shall be provided between a command to start (0=1) and a run status output (R=l).
MSIM shall perform as follows:
If W=1 and 0=1; after (T) times out, R=l
If W=1 and 0=0; R=O
If W=O R=O

AG, MUL-Multiplier - The MUL module shall employ the following equation:
Output = Kl * (X) * (Y) + K2
where:
X and Yare the values to be multiplied
Kl = scaling coefficient
K2 = bias
AH. NOT-Not - the NOT module shall generate an output "1" if, and only if, the input does not
have the value "1 ".
AI. OR-Or - The OR module shall generate an output "1" if one or more of the inputs are "1".
AJ. PFRST-Power Failure Restart - Major plant equipment is presently installed with time-delay
relay circuits to allow for automatic, sequenced start-up. When power returns, equipment
will come on according to the pre-set hardware time delay. It is imperative that the control

system work in conjunction with this hardwired function. In order to do so, the PFRST
function will perform the following:
1. Monitor the "AC Power Lost" (Alarm contact provided by the controller unintemuptible
power supply). This will be accomplished by wiring it to a digital input. This digital
input will be continuously scanned.
2. When a power loss is detected, the condition will be alarmed to the workstations and
the software will freeze the operation of all discrete and analog alarm primitives (i.e.
system will track but not alarm conditions caused by the power failure) and all control
executing in the affected controller (s) and the maximum outage timer shall start.
The freeze shall remain in effect until power has returned. During this freeze, all
analog and digital outputs will remain at their last commanded state.
3. When power has returned, the controller will continue to be frozen for a pre-set time
(Max Restart Time). This will allow all time-delay relays to time out and the
hardwired sequencing function to be achieved.
4. After this amount of time, the freeze will be released, and all discrete and analog
control functions will continue at the point of execution before the power failure. All
discrete equipment that did not return to its original state will have its outputs turned
off and a deviation alarm will be issued. This mode of execution will occur unless the
maximum outage timer has timed out. If this timer times out all equipment will be
returned to the manual control mode and a stop command issued.
AK. PID-Proportional plus InteQral plus Derivative - the PID module is an incremental version of
the feedback control algorithm used in analog controllers. The result of each module
calculation is an incremental change to the manipulated variable which may be a valve
position or motor speed as shown on the Drawings. The PID moduie shall either have its
output connected to a final control element or cascaded to another module. The output of
the control module (OM) includes all changes computed for the proportional (DMp), integral
(OM;), and derivative (DMd) modules as shown in equation (1).
OM = DMp + OM; + DMd
Equation (1)
Other control modes, such as P, PI, PO and I shall be derived from equation (1) by deleting
terms as required. In order to provide this modularity, the PID module shall be divided into
three blocks (P, I, and D).
The required modules are presented below:
1. Proportional Module (DMIll. - Two proportional modules shall be provided. Equation
(2) is based on the error between set point and the process variable and should be
used only for fast loops where set point response is important, such as in a cascade
control system.
DMp=(100/PB) * (DEn) Equation (2)
Equation (3) is based on the process variable and should be used for most cases
when coupled with the integral module because it results in a lower degree of
process upset due to set point changes.

3.02 AERATION SYSTEM CONTROL STRATEGY
A. Process Overview
1. The MLE Aeration System is composed of three Aeration Tanks and five blowers.
The blowers are composed of three existing 300 HP, one new 300 HP and one
existing 150 HP multistage blowers feeding air to three adjacent MLE Aeration Tank
Nos. 4, 5 and 6.
a. Each MLE Aeration Tank is divided into four basins: A, B, C and D; and the air
flow to each basin is controlled independently. The air from the blowers is
forced through find bubble diffusers supplying oxygen to microorganisms and
to provide mixing of suspended solids in each aeration basin.
b, The air to each aeration basin is controlled by a dedicated PID air flow
controller that is modulating the motorized influent valve to maintain the
desired air flow setpoint to the basin. The air flow setpoint to each basin shall
be determined by the operator. The air flow to each basin is measured by a
Venturi Tube mounted upstream of the motor operated modulating valve.
2. The MLE Aeration Control System is composed of the following two major control
strategies:
a. Blowers Air Pressure Control: In Automatic Mode, the 300 HP Lead blowers
shall start and the logic shall perform the following automatic functions:
I. Control the blower inlet throttling valves based upon the blower's air
discharge pressure.
ii. The blower air pressure controller shall modulate the blower inlet
throttling valves to maintain the blower's discharge air pressure to a
proper pressure setpoint.
III. The automatic Lead/Lag blower logic shall start/stop the blowers based
upon the blower inlet throttling valve position and blower motor
amperage by performing the following increasing blowers demand
sequence:
Step 1 - 300 HP Lead Blower
Step 2 - 300 HP Lead Blower + 150 HP Lag Blower

The Lead/Lag logic shall continuously monitor the blower motor current
and the blower inlet throttling valve position of the running blowers to
start/stop additional blowers. The logic shall request a Lag blower to
run when the blower motor current and the blower inlet throttling valve
of the running blowers increases above the adjustable current and
valve position setpoints for and adjustable time duration. The logic
shall operate exactly in the same manner when a Lag blower is
requested to stop due to low blower motor current and/or blower inlet
valve position of the running blowers below the minimum operator
adjustable valve position setpoint
IV. When the automatic Lead/Lag control logic starts/stops a blower, the
logic shall not allow another blower to start/stop for an extended
adjustable time duration of about 60 minutes. That will allow the
running blower to stabilize the air pressure.

RE: Collier County - PW
Notification of Use of General Permit
North County Regional Water
Reclamation Facility Compliance

Permit No. 299087-001-DSGP
(Collier County Regional WTP)
Southwest Coast EMA
Dear Mr. Schalt:
In response to your request, this letter is to advise you that the Department has received your
notice of intent to use a general permit as provided in Rule 62-555, Florida Administrative Code
(F.A.C.) to construct an extension to a public water supply distribution system and does not object
to your use of such general permit.
This authorization does not relieve you from the necessity of obtaining any and all other permits
necessary. Specifically, this authorization does not constitute approval for work within wetland
areas or alteration of mangroves subject to Chapters 373 and 403, F.s.
Please be advised that you are required to abide by all conditions in Rules 62-4.510 through 62-
4.540, F.A.C., the general requirements for general permits, and Rule 62-555.405, F.A.C. This
general permit will expire January 26, 2015. If the project has been started but is not complete
by that time, a new permit must be obtained before the expiration date to continue work on
the project per F.A.C. Rule 62-4.030.
Sincerely,
ae:/:-
