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.

Administrative Building Construction

Project Accomplishments:

In the month of February, Hensel Phelps completed the concrete slab on grade for the new Administration Building. This milestone included below slab and retaining wall waterproofing, under slab mechanical systems, double mat reinforcement, installation of in-slab mechanicals and passing floor flatness and level testing. Retaining walls have now been backfilled and the building perimeter graded and prepped for delivery of the structural steel erection crane. Final design packages were also completed, furniture systems and equipment reviews and transition /move-in planning has begun for the occupants of the new building. Looking to March, the site will be receiving deliveries and erecting the structural steel as the project moves to the vertical stage. A "Topping-Out" ceremonyis planned for late in the month.
