June 17, 2008 Agenda Item – West Baldwin Creek
Interceptor Sewer Utilities
Department Project #CS0704 Award Bid |
Please include the following item on the City Commission
agenda for consideration at the June 17, 2008 meeting:
Award the bid for
Project CS0704 West
The
project began with a preliminary design-build agreement for engineering design
to be completed to a level that would allow development of a guaranteed maximum
price (GMP) for the construction of the project. A GMP was developed and a contract
prepared. Staff did not recommend
proceeding with the GMP contract and instead recommended completing the project
as a design-bid-build project to ensure a fair market value for the
construction contract.
The
project will construct approximately 15,000 feet of gravity sewers ranging in
size from 10” to 30” that were identified in the 2003 Wastewater Master Plan as
E-BC-1-02, E-BC-2-01 and E-BC-2-02. The
project will connect to and extend the gravity sewers constructed with the Pump
Station 48 project. The general area involving the project is shown on
the attached map.

It
should be noted that the design-build construction cost includes $580,000.00 in
allowance costs that were to be used only if the specific scope of work was
encountered. Any allowances that were unused would not be paid as part of the
GMP contract. In the design-bid-build project, there are no allowance items.
The contractors bidding on the project must account for these items in their
bid.
We
anticipate the following schedule for the remainder of the project:
June 2008: Award construction contract.
April 2009: Final construction completion.
This
schedule is contingent upon the contract execution and weather conditions during
the construction period.
Project Funding
Funding
for the project will come from the Utilities Department Capital Improvement
Project bonded construction fund.
