Administration Building/Jail Demo & Redevelopment

The County Administrator’s Office and Public Works Department engaged the design-build team of Webcor/Perkins & Will in the fall of 2021 to deliver the Administration Building and Jail Demolition & Redevelopment Project (ADR). The project will include demolition of the Old Administration Building at 651 Pine Street as well as the Jail at 650 Pine Street. The site will then be developed with a Satellite Administration Building and Public Plaza, continuing the County’s investment in Martinez and further enhancing the County’s campus along Pine and Escobar Streets.

The new Satellite Administration Building will provide 74 parking spaces and a tenant space on Level 1. Level 2 and 3 will offer approximately 42,000 sf to house various County departments. Intimate areas will provide quiet retreat while larger spaces will support various events. The project is pursuing a LEED Gold certification and Total Resource & Efficiency (TRUE) Gold certification.

Since our fall update, the building’s interior spaces have been completed and begun the final punch list process. Over December and January, the focus for the builder team was completing the interior finishes. PGE provided power to the new building at the end of December and final connections for fiber optic connectivity are currently underway. The entrance Lobby – which incorporates marble and wood finishes from the 651 Pine tower – has completed with the addition of a glass rail at the accessible ramp from the garage.

In February, exterior site work has continued. The future pedestrian plaza is taking shape as the colored concrete, various paver materials and plantings all continue to be installed. While the rain has presented challenges for the team, underground infrastructure work is almost complete. Commissioning of the building systems at the interior and exterior will begin at the end of February and lead directly toward anticipated occupancy inspections in March, with furniture installations to follow.

Did you know. . . As part of the project, the County has partnered with the City of Martinez to provide replacement of aging underground water infrastructure. The water main line which connects the Main Street and Escobar Street runs has been brought up to current standards as specified by the City.

The Administration Building TRUE Zero Waste Management Goals


The Administration Building and Jail Demolition & Redevelopment Project (ADR) is pursuing Total Resource Use and Efficiency (TRUE) certification.  TRUE is a zero waste certification program used to define, pursue, and achieve zero waste goals, cut the carbon footprint, and support public health.  The ADR will be the first construction project pursuing TRUE Certification, making the County a world leader in the TRUE zero waste movement for the public sector! 

TRUE is administered by Green Business Certification Inc. (GBCI) and the main goal is to divert 90% of solid waste from landfill, incineration, and the environment.  TRUE promotes the redesign of resource life cycles so all products are reused.  Following these principals the County’s project will have a lower waste output and be more environmentally responsible.  


The County and Design-Builder are working on various practices to reduce waste during the demolition phase of the project.  A few examples include:

  • Reuse of furniture and office supplies from the existing building in other County buildings and the contractor’s field trailers.
  • Reuse of fire extinguishers, lights, interior windows in the contractor’s field trailers and site operations.
  • Pursuing closed loop lifecycle opportunities, e.g. concrete reused for subbase or winterization of the site. 
  • Developing and adapting a Zero Waste Policy:  ADR Zero Waste Management
  • Promoting waste reduction in different operational areas, e.g. the jobsite trailer will not have a printer onsite to reduce waste and all construction documents will be available virtually. 

Reuse efforts will continue during the design with:

  • Salvaging and reusing existing marble wall panels in the new building lobby.
  • Salvaging and reusing existing granite block in the new plaza hardscape.
  • Selecting building materials with recycled content.
  • Reusing or returning packaging of products or building materials that are delivered to the site.

Together these efforts contribute to the County’s goal of zero waste, but on an even larger scale they’re reshaping how people and companies approach construction and building materials.  TRUE pushes each of us to think outside the box to promote a circular economy in our projects.
