RECOMMENDATION:
Recommendation
Authorize reducing the current construction contract retention of ten percent (10%) to five percent (5%), consistent with the minimum amount required by the California Public Contract Code.
Body
SUMMARY:
On June 28, 2016, the Board awarded the construction contract for the Lower Berryessa Creek Flood Protection Project (Project) to Brosamer & Wall, Inc. (Contractor) in the amount of $38,876,550, and approved a ten-percent (10%) contingency of $3,887,655. The project is in the third year of the three-year construction schedule. A reduction to the construction contract retention is recommended since the substantially complex work is complete and the remaining work is of minimal risk, consisting of standard levee and floodwall construction. Taking this recommended action is consistent with statutory requirements.
