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.

The Administration Building and Jail Demolition & Redevelopment Project (ADR) has transitioned from demolition into construction. This is a significant milestone for the project team! Removal of debris from the Old Administration Building Tower completed in November and the design-builder began backfilling the area to build the ground pad for the new building. The pad is expected to be certified in early December which will allow digging of foundations to begin. The goal is for the first concrete pour to occur before the end of the year.

The project site is constricted with new work occurring up to the project fence. Therefore, the design-builder is focused on the north end of the site where the building will be constructed. The south end of the site where the plaza will be located is untouched for now and serves as a lay-down area for materials, trailers, and equipment. The south end of the site was prepped with an aggregate rock so the design-builder could work through the rainy winter months.

The project team continues to work with permitting agencies such as the Department of Conservation & Development (DCD), City of Martinez, and County Public Works to document refinements to the design and establish inspections processes. Permitting also continues with PG&E for permanent power to the building. The project team has worked diligently with PG&E to develop a design that satisfies the needs of the County and will be installed by PG&E before the building is complete.

Did you know….On November 2, 2022, Contra Costa County was recognized as a leader in sustainability and innovation at the Greenbuild International Conference at the Moscone Center in San Francisco. The Administration Building and Jail Demolition & Redevelopment Project (ADR) has become the first government construction project in the world to achieve Total Resource Use and Efficiency (TRUE) pre-certification. Pre-certification is the first step to achieving TRUE certification which is awarded at the conclusion of the construction based on the total performance of the project. Read more about TRUE below.

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.
