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:

The Administration Building project has been a busy and crowded site this past month. Trenching and installation of the City storm drain system at the west end of the site have generated spoils that will be off hauled by the end of the month. 

This portion of the system has been reviewed and approved by City and County inspectors. Materials  for  the  eastern portion of the City storm drain system have been delivered and stored on site.  

The service elevator pit constitutes the low point of the building and has now been formed, poured, waterproofed, corresponding  inspections completed, and backfilling is in progress. Forming and reinforcement in preparation for the pouring of the eastern foundation pile caps is underway while the pile grout strengths are being confirmed. 

Placement of these pile caps is planned for the end of October. Project permitting achieved Design Package #4 milestones with approvals for Architectural, Mechanical, Electrical, and Plumbing systems and approval from the Fire Protection District.
