GROWTH MANAGEMENT DEPARTMENT
MEMORANDUM
DATE: September 30, 2015
TO: File—Chokoloskee Bridge Replacement, Project# 66066.9
FROM: Andrew Miller, P.E., Senior Project Manager
Collier County Transportation Division
SUBJECT: Back-up Memo for Change Order#4
The Chokoloskee Bridge Replacement Project, originally scheduled to begin construction in the
fall of 2013, has undergone several design changes and permit delays that have significantly
affected the timeline for completing the project. On a positive note, the latest obstacle
encountered,the USCG permit, has finally been approved as of September 7, 2015. The
invitation to bidders was advertised on September 28, and it appears that construction can begin
in the upcoming months.
The design contract for TY Linn has undergone three previous change orders for additional time
and fees related to the design and permitting issues described above, but due to the last delay due
to obtaining the USCG permit, the current contract will expire prior to project close out.
Additionally, the design change eliminating the use of a temporary detour bridge and now
proposes a staged construction of the new bridge, although saving significant construction
dollars, will very likely result in an increase in requests for information(RFI's) from the
engineer of record. This change order provides the consultant with adequate time and fees to
remain available for post design services through the completion of construction.

Provide a response to the following: 1.) detailed and specific explanation/rationale of the requested change(s)to the task(s) and/or
the additional days added (if requested); 2.)why this change was not included in the original contract; and, 3.) describe the impact if
this change is not processed. Attach additional information from the Design Professional and/or Contractor if needed.
1.) detailed and specific explanation/rationale of the requested change(s)
Due to the extensive time required to obtain a United States Coast Guard Permit for the construction of the new bridge,
the subsequent delay of the construction start date has depleted the contract time allotted for the consultant to complete
post-design services. In addition,the phased construction of the bridge, along with unknown subsurface site conditions
will very likely result in above normal requests for information (RFI's)and submittal I reviews which will require
additional post design services than previously budgeted in the original contract.
Change Order 4 will provide sufficient time and funding to provide Post Design Services for the designer of record to
serve the project through advertisement,award, construction and project close out of a $6.9 million construction project
on an 18 month construction schedule.
2.) why this change was not included in the original contract;
The initial contract allowed for a reasonable time to obtain the various permits required prior to beginning construction,
and in particular allowed for approximately 326 days to obtain the permit from the USCG. The application for the USCG
permit was submitted July 11, 2014,and was finally approved September 8, 2015(423 days). Post-design services were
included in the original contract but the complexity of the design and construction was not known at that time. This
change order will increase Post design Services from the original amount of$38,000 to a total of$73,000 to administer a
$6.9 M construction project.
3.) describe the impact if this change is not processed.
The engineer of record would not be available subsequent to the expiration of the current contract time and fee,and
issues arising during construction that would require his expertise would very likely cause delays and cost over-runs.
The bridge at this location is vital to the safety and welfare of the people of Chokoloskee as it their only link to the
mainland. It is critical that the construction team of the new bridge have access to the design professional until the
project is complete.

Re: CR 29 Bridge over Chokoloskee Bay,Collier County Florida
Bridge Number 030161
Dear Mr. Putaansuu:
Since the United States Coast Guard Permit for the new bridge construction has now been issued,
we understand the project is moving towards advertisement for construction. Due to the
extraordinary time required to secure said permit, the contract time limits on our current design
and post design contract with the County is in danger of expiring (August 17, 2016) prior to
construction completion. In addition, due to the complex nature of the phased-construction
design, remote site conditions and unknown sub-surface conditions we anticipate the amount of
Requests for Information and Submittal Reviews will exceed the normal and previously
negotiated hourly fee budget for post design services.
Accordingly, T.Y. Lin International (CONSULTANT) proposes to provide the following
additional services in accordance with Contract 11-5639 ARTICLE TWO:
1. Provide Post Design Services during construction operations as defined in Section
2.1 of Contract 11-5639.
2. Increase the Time for project completion by 600 days.
The above described services were part of the contract scope, but are being supplemented and
extended due to project complexity and regulatory and administrative scheduling. If this change is
not incorporated, the CONSULTANT will be unable to fully support staff and the construction
team with technical reviews, plan modifications, drawing interpretations, etc. typically required
for a project of this complexity.
CONSULTANT proposes to provide the above services for an additional Hourly/Not to Exceed
fee amount of$35,016 in accordance with the conditions of Contract 11-5639.
Please call if you need additional information on this matter.
Sincerely,
Jim Molnar, P.E.
