Agenda 07/26/2011 Item #16A167/26/2011 Item 16.A.16.
EXECUTIVE SUMMARY
Recommendation to approve Change Order #6 in the amount of $355,916.44 to contract No. 10-
5366 with Stevens and Layton, Inc. to complete the Gateway Triangle Phase 2 Stormwater
Construction project (Project #51803).
OBJECTIVE: Recommendation that the Board of County Commissioners approve Change
Order # 6 to complete the Gateway Triangle stormwater construction project.
CONSIDERATIONS: On December 15, 2009, the Board of County Commissioners awarded
Contract # 10 -5366 to Stevens and Layton. Inc., for the construction of the Phase 2
Improvements to the Gateway Triangle Stormwater project (Project #51803, Agenda Item IOB)
for $2,694,473.35. Since that time, the Contractor has worked diligently on the project and has
completed 90% of the work. As part of the project, the plans called for the Contractor to
directional bore under US 41 at Palm Street to provide a south outfall for the stormwater
management system. After twelve (12) directional bore attempts, the Contractor was
unsuccessful in crossing US 41 due to the extraordinary geological formation and conditions that
exist in this specific area. The weak soils below the cap rock, a high water table, tidal influences,
and a liquefied material below the rock level caused these bores to fail. As a result, the County
had to re- permit the crossing with FDOT as an open -cut crossing, opening up the road surface to
complete the work. This pennitting process has recently been completed and now the County is
ready to attempt the open -cut stormwater outfall crossing. This project is in a critical time frame
due to the impending rainy and hurricane season peak. Change Order #6 is needed for the
contractor to complete the work.
FISCAL IMPACT: Funds are available under Stormwater Capital 325 Fund. Funds in the
amount of $214,316.44 are available in the Swale Maintenance Repair, project # 60093 and
funds in the amount of $141;600 are available in Secondary System Repair, project 960094. A
budget amendment in the amount of $355,916.44 is needed to move funds from these projects
into the Gateway Triangle Stormwater project #51803. $112,567.37 will remain in contingency
for this project within the existing purchase order. These contingency funds were previously
BCC approved and shall only be used, via a new change order, if they are required to complete
the project.
LEGAL CONSIDERATIONS: This item has been reviewed and approved by the County
Attorney's Office, is legally sufficient for Board action and only requires a majority vote for
approval —SRT.
GROWTH MANAGEMENT IMPACT: The project is in accordance with the goals and
objectives of the Drainage Sub - element of the Growth Management Plan for Collier County
Stormwater Management.
RECOMMENDATION: That the Board of County Commissioners approve Change Order 96
in the amount of $355,916.44 and the necessary Budget Amendments needed to fund the
completion of the Gateway Triangle Stormwater Phase 2 Construction project.

Project: Gateway Triangle Stormwater Project # 51803
Improvements, Phase 2 Construction Contract #10 -5366
Contract date: December 15, 2009 PO# 4500115437
Change Order: # 6 Date: Julv 7. 2011
Change Order Description:
On December 15, 2009 the Board of County Commissioners awarded Contract # 10 -5366 to
Stevens and Layton, Inc. for the construction of the Phase 2 Improvements to the Gateway
Triangle Stormwater project (Project #51803, Agenda Item 10B) for $2,694,473.35. Since
that time, staff has administratively approved Change Order #1 in the amount of $9,116.60
on March 10, 2010 for the use of ductile iron pipe and fittings in lieu of the specified HDPE
pipe, in order to minimize the business disruptions that are caused by extensive trenching
required for the HDPE pipe.
Change Order #2 was administratively approved in the amount of $54,118.75 on August 16,
2010 to extend an elliptical pipe to pick up additional drainage, relocate additional water
mains, install conduit for FPL, extend a directional bore, installation of a gate to ease
maintenance access, move and cap an existing force main, unforeseen reconfiguration of
roadside drainage system, and to allow 34 days of additional contract time for the project.
Change Order #3 was administratively approved in the amount of $83,643.93 on December
28, 2010 to change from a jack and bore to a directional bore under Davis Boulevard which
resolved conflicts with utilities at that intersection, site improvement plan changes at the
stormwater pump station caused by permit and site development requirements, miscellaneous
changes including water main diversions, removal and replacement of existing failing
culverts, additional roadway work, install safety grate and brick bulkhead due to concerns
from the Brookside community, and to allow for 22 days of additional contract time for the
project. On February 8, 2011 Change Order # 4 was administratively approved to provide an
additional 90 days to the contractor. This added time allowed for a twelfth and final
directional bore under US 41 The directional bore under US 41 at Palm Street is in an area
of tenuous subsurface strata. The Contractor had attempted I 1 bores there, to no avail, in
crossing under US 41 with a drainage outfall pipe for the Gateway Triangle Stormwater
Project. Additionally, the County had to bring in an outside Materials Geotechnical Testing
firm to test bore the strata on the south side of US 41 to determine what was causing the
complications with the directional bores. This new test bore substantiated the test bore
information provided in the original design plans and showed extremely weak soils below the
caprock which explains the difficulties with the boring operation. This additional testing,
and the uncertainty of the timing of the construction of the directional bore and subsurface
piping, required the County to provide adequate time for the Contractor to safely complete
this critical work. Additionally, the stormwater pumpstation had encountered further
complications resulting from the heavy components that are being placed in the building
structure; spatial issues, and issues relating to final testing of the components that required
time be provided for these tasks. Utility issues had also resulted in the need for additional
time for the project. The County hired a firm outside of this contract to provide fiber optic
facilities for the telemetry of this pumpstation. Complications in permitting and directional
boring of the service line had caused the project a time delay in bringing the network
functionality on -line. This has caused the contractor to be unable to tie in the system to the
IT network management system. Also, the City of Naples Utilities department had required
additional permitting for the installation of a fire hydrant which caused additional time
Packet Page -1416-
7/26/2011 Item 16.A.16.
Change Order No. 6
Page 2
additional permitting for the installation of a fire hydrant which caused additional time
requirements for the design and permitting of this issue. These issues were all handled with
Change Order 94.
Since approval of Change Order #4, the Contractor attempted directional bore #12 and the
bore failed due to the strata at the site. The Contractor at the same time continued working
on the remaining pacts of the project and completed that work, leaving the south outfall
(crossing of US 41 at Palm Street) as the only substantial work remaining. After twelve (12)
failed attempts at a directional bore, the design has been revised to an open -cut method for
the crossing of US 41. To do this required applying for a revised permit with FDOT and the
time needed for the permit to process. Additionally, the County brought in a consultant to
perform sub - surface utility engineering (S.U,E.) to identify all of the utility conflicts with the
new open -cut crossing of US 41. In order to allow for this re- deign, re- permitting and change
in construction, the County provide the Contractor with an additional 150 days to complete
this work, which constituted Change Order # 5.
Since approval of Change Order #5, the FDOT has issued a permit for the open cutting of US
41 to allow for the revised crossing. Change Order #6, in the amount of $355,916.44,
provides for the material and labor to cross US 41 from Commercial Drive to Palm Street.
This work will be done at night and will require substantial maintenance of traffic (MOT)
and lighting. Deflections of the stormwater drainpipe will be made around the existing
utilities that are in conflict with the new stormdrain line. The costs also include resurfacing
and re- striping of the roadway after completion of the open cut and will compensate the
Contractor for the failed bore attempts. Additionally, this pricing also includes additional
miscellaneous items necessary to complete the project, including sod, paver installation,
sidewalks, shrubs, mulch, punrpstation controlling, electrical outlet, cutting and revetment of
a storm drain pipe and adjustment to a manhole. No additional days are being allocated with
this Change Order # 6. This Change Order requires BCC approval since it exceeds 10% of
the original contract amount as outlined in the County Purchasing Policy.- $112,56737 will
remain in contingency for this project within the existing purchase ordei�(These contingency
funds were previously BCC approved and shall only be used, via a new change order, if they
are required to complete the project. %:''i
