EXECUTIVE SUMMARY
Recommendation that the Board of County Commissioners of Collier County, Florida, as
Ex-Officio the Governing Board of the Collier County Water-Sewer District, approve a
deductive change order in the amount of $57,622.94 to a work order to Mitchell & Stark
Construction Company, Inc. for construction of the water main replacement necessary to
accommodate the replacement of the Vanderbilt Drive Bridge over the Cocohatchee River,
Project 70045.
OBJECTIVE: The public purpose is to provide uninterrupted potable water service to
customers in the northwestern part of the water service area by the replacement of a 12-inch
water main required by the replacement of the Vanderbilt Drive Bridge over the Cocohatchee
River.
CONSIDERATIONS: On October 14, 2008, Agenda Item ]6 C 3; the Board passed a
Resolution approving a FOOT standard "Utility Work Agreement" (UW A). The UW A pertains
to the County construction of a replacement water main required by the FDOT project to replace
the Vanderbilt Drive Bridge.
On October 28, 2008, Agenda Item lOB; the Board approved a Locally Funded Agreement
between the FOOT and Collier County for construction of the bridge, which includes
bicycle/pedestrian improvements desired by Collier County. The County's share is funded by a
portion of the $3 Million mitigation collected from the Cocohatchee Bay Settlement Agreement.
On January 13, 2009, Agenda Item 16 C 2; the Board approved a work order to construct the
replacement water main to Mitchell & Stark Construction Company, Inc. under Contract 08-
5011, "Annual Contract for Underground Utility Contracting Services."
Staff seeks the Board's approval of a change order to Mitchell & Stark Construction Company,
Inc., which reconciles actual final quantities with estimated quantities and also incorporates
additional modifications required by unforeseen conditions found during construction. The net
result is a deductive change order.
During construction it was determined that existing underground stOlm drains and utility lines
prevented the construction of large permanent vaults for meters and piping as designed. Staff
determined that smaller meter vaults could be used for leak detection meters without the need for
extensive piping in the vaults. Staff also detern1ined that the length of pipe to be pigged and
flushed could be reduced to only the length of new pipe installed. Both of these measures
resulted in major reductions in costs.
Also, for a small increase in cost, cutting three valves into the existing main was required, in
order to maintain service to customers if a break should occur in the new main or in the existing
mains under the new pedestrian bridges to the south.
FISCAL IMPACT: Funds totaling $57,622.94 will be returned to Gas Tax Capital Fund 313,
~ which holds the proceeds from the Cocohatchee Bay Settlement Agreement.
