County Administration Building

The new 71,000 square foot County Administration Building will be located at 1025 Escobar Street in downtown Martinez.  It will be four stories in size, and house a variety of County departments, and include the Board of Supervisors meeting chamber.  

Parking has always been a challenge near the current, aging McBrien Administration Building.  The new building will have nearby parking for 250 vehicles, including an increase of approximately 75 spaces for the public.  In addition, there will be public plaza areas where the 12-story building now sits at 651 Pine Street.

Project Accomplishments:

Despitesome inclement wet weather, the Administration Building project site continued to be busy during December. Utility workalong Marina Vista and Escobar Streets was part of the sequence to complete the new storm water system.  Hensel Phelps and their subcontractors, Preston Pipelines and OC Jones, worked to minimize traffic impacts and complete the work efficiently – placing new trenches, pipes, and drain structures as part of the City of Martinez approved project.  Both the new storm drain andnew sanitary sewer systems were activated and the existing infrastructure at Pine Street grouted and abandon. In addition, on-site foundation work continued with completion of all pile caps, forming, reinforcing, and placement of retaining walls and waterproofing. Underslab plumbing work passed inspections in late December with subgrade electrical system installation following shortly thereafter. All this being done in preparation of the upcoming slab pours in January, 2019.  Minor design work continues on final DP4 package, bulletins, and plans for the new parking deck at the existing Martinez Detention Facility parking lot in order to obtain approvals from DCD in January.
