New County Administration Building & Master Plan

STATUS Under Construction | TYPE Civic Office | CLIENT Contra Costa County | SIZE 71,000 SF | COST $95m est. | COMPLETION 2019 est. | Designed to LEED Gold

MARTINEZ, CA, USA  The New County Administration Building will replace the current McBrien Building and is designed to be more efficient and community-friendly. It will stand four stories tall and house a variety of county departments, along with the Board of Supervisors meeting chamber. Our design blends civic character with a warm and welcoming atmosphere.

The project included the master planning and strategic phasing of several blocks in downtown Martinez to include parking and civic plazas carefully designed to bring cohesion and better flow to the government district. Surface parking will accommodate 250 vehicles, 75 spaces more than the current, 12-story McBrien Building at 651 Pine St., a block away from the new site. Public plaza areas will replace the space currently occupied by the McBrien Building. Included in the scope is the re-use of the 1904 “Old Jail” and demolition of the connecting 1940s Annex structure with the possible addition of a new circulation core of about 500–600 GSF per floor. 

KMD completed the project through Bridging Documents. The new building is currently under construction by the design-build team of Hensel Phelps/Fentress Architects and Dreyfuss and Blackford Architecture with ongoing reviews by KMD.
