DISCUSSION:
Overall Contract Cost/Time Summary
The work necessary for the completion of this contract consisted of demolition of the existing
chafer panel, floating cover and appurtenances, salvage of existing equipment and materials,
installation of a 45 -mil chafer CSPE, 35 -mil CSPE vertical baffle, 45 -mil CSPE floating cover,
cover appurtenances, hatch, vents, floats, sand tube weights, sump pump dewatering
assembly, and storm water drainage pipe system. Additional work items were added to the
scope of work during construction that included modifications to improve the design,
maintenance, and landscaping of the adjacent lot.
The contract has now been completed to the satisfaction of the Public Works Department.
A summary of the contract cost is as follows:
Original bid amount: $ 5,720,500.00
Actual cost of bid items constructed: $ 5,720,500.00
Total change orders: $ 265,492.00
Final contract cost: $ 5,985,992.00
The cost of bid items constructed decreased with the deletion of the following scope of work(s):
reservoir dewatering, substitution of doubler material over the grillage, reservoir disinfection
chlorine (provided by the Contractor) and other items. The final construction contract cost was
approximately 4.6 percent above the original bid amount through the added work that included
modifications to improve the design, maintenance, and landscaping of the adjacent lot. A
portion of this cost increase resulted from the modifications to the baffle design, and to provide
cleaning of the reservoir at a future date.

Project Awarded for Construction 2/26/2013
