The work necessary for the completion of this contract consisted of replacing
deteriorated manually operated tidegates with new self - operating tidegates and
hardware units at 11 locations throughout the Balboa Peninsula and Balboa Island. By
design, the new self- operating tidegates operate by opening and closing as a result of
pressure changes due to tidal fluctuation, thus reducing operation costs associated with
a manual tidegate system.
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:
$ 126,620.00
Actual cost of bid items constructed:
$129,960.00
Contract change orders:
$ 8,175.00
Final contract cost:
$ 138,135.00
The final overall construction cost, including one change order, was approximately 9.1%
above the original bid amount. The change order was for replacing two deteriorated
concrete storm drain collars, building a concrete stem wall, and installing a new storm
drain outlet.
A summary of the project schedule is as follows:
Estimated Completion Date per July 2012 Baseline Schedule: November 21, 2012
Project Awarded for Construction: July 10, 2012
Completion Date from Award with Approved Extensions: February 8, 2013
Actual Substantial Construction Completion Date: January 31, 2013
