The project consisted of improvements to an existing data center facility. The data center was non-operational. The scope of this project involved electrical upgrades and specialized cooling for the new data center equipment. It included, but was not limited to, installation and and anchoring of 25 owner-furnished cabinet assemblies (88.5"x30"x48"), procurement and installation of two (2) redundant, parallel uninterrupted power supplies (150kbs/480V), power distribution units, busways and supporting infrastructure including conduit, conductors and associated structural supports and bracing. Demolition and modification of existing electrical equipment and circuits were required. In addition, the scope included procurement and installation of row based, air cooled, precision cooling systems.
A construction contract in the amount of $983,900 for the Bisso Data Center Improvements was awarded on February 25, 2020, to Aztec Consultants of San Ramon. The project has now been completed and the Public Works Director recommends that the Board adopt Resolution No. 2020/332 accepting the contract work as complete.
Acceptance of a contract as complete is standard procedure and allows for proper closeout of the contract. If the contract is not accepted as complete, the period for filing stop payment notices and bond claims may be extended and then Contra Costa County will incur expenses for additional contract administration.
