Contra Costa County Administration Building

Project overview

The four-story Contra Costa County Administration Building is a LEED Gold certified facility and a focal point in downtown Martinez. It houses a variety of County departments and includes the Board of Supervisor’s meeting chamber, with a total capacity for 250 people. Vanir provided project and construction management services for this facility.

The Administration Building was designed and built concurrently with the County’s new Emergency Operations Center/Public Safety Building, also managed by Vanir. At our recommendation, the projects were combined into a single design-build procurement with an aggressive schedule. This allowed the County to nearly simultaneously vacate an inefficient and outdated 12-story shared office tower and move into the new facilities.

Another recommendation by Vanir, to break off make-ready projects that were designed (and in some cases constructed) prior to having the design-builder under contract, helped meet the County’s timeline.

Vanir played a key role in the delivery of two critical buildings in less than three and a half years, in the face of a global pandemic— where all other previous efforts to develop the new facilities over several decades had failed…I cannot imagine a more award-worthy example of successful project and construction management.
