TITLE
Recommendation to adopt Plans and Specifications No. R-6786 for the Temple Avenue Bridge Repair between 29th Street and Spring Street, and authorize City Manager to award the contract to Peterson-Chase General Engineering Construction, Incorporated, in an estimated amount of $1,150,000 plus a 25 percent contingency of $287,500, if necessary and if funding is available. (District 5)

Two City-owned corrugated metal storm drain pipes were installed in 1961 within the Temple Avenue Bridge over the San Diego Freeway when the freeway was constructed. The purpose was to convey storm flows northerly across the freeway to a storm drain system located in Spring Street. During a recent bridge inspection, Caltrans noticed evidence of water damage to the bridge structure and, after further investigation, determined that these City-owned storm pipes had deteriorated and needed to be immediately replaced to prevent further water damage to the bridge structure.

The plans for permanent replacement have been completed and bids have been received. Work will consist of removing the old deteriorated metal pipes from within the bridge structure and installing two new 42-inch pipes within a separate section of the bridge.

The contract requires that all work be coordinated with Caltrans and the City of Signal Hill.
City Council's adoption of the plans and specifications and award of the contract to the lowest responsible bidder are being recommended concurrently in order to expedite implementation of this project. The project was advertised for bid on May 15, 2009, and bids were opened ...
