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.
As of the end of September work on the Administration Building included rapid completion of the foundation displacement piles, removal of the existing underground petroleum storage tank, and off hauling of impacted soil materials. Dewatering of the site was performed as needed to allow for excavation of the service elevator pit. This area has now been backfilled, forms set, and rebar will be placed for inspection of the pile cap prior to the concrete pour during the first week of October. Excavation for pile caps in the vicinity of retaining walls at the southeast and northwest corners of the building have begun.
