The Contra Costa County Administration Building & Jail Demolition and Redevelopment (CCC ADR) team recently topped out the third floor of the county’s new administration building, a major milestone and testament to the entire design-build team’s efficient, seamless collaboration.

On May 2, the team celebrated with a traditional Webcor BBQ attended by our dedicated trade partners: PSG Rebar, Contra Costa Electric, J.W McClenahan, Cosco Fire Protection, Peterson Mechanical, Viking Steel, Commercial Exteriors, Applied Materials & Engineering, Best Roofing, Valley Waterproofing, and Vanir Construction Management. Representatives from lead architect Perkins&Will and project client Contra Costa County also joined the festivities.

Speakers included Chief Assistant County Administrator Eric Angstadt from Contra Costa County, who thanked the team for a smooth adjustment to this year’s unprecedented weather delays and shared the community’s gratitude for the project’s lack of disruption to their daily activities; Deputy Project Director Santiago Harris from Vanir Construction Management; Assistant Construction Manager Matt Delaney from Vanir Construction Management; Superintendent Dan Deane from Webcor Concrete; Regional Manager Camden Story from Hex Armor, who gave a Safety Week talk on HexArmor’s unique, sustainable safety gloves that meet ANSI/ISEA 138 standards and align with CCC ADR’s TRUE Zero Waste goals; and Webcor Sr. Superintendent Justin Marsh.

Justin congratulated the entire team on reaching this highly anticipated project milestone with zero lost-time injuries, noting that they had spent the last few months consistently delivering high-quality work on an accelerated, stringent schedule while combatting unexpected winter weather challenges.

“Performing the concrete scope during an exceptionally rainy winter has definitely been the most notable challenge of the last few months,” Justin says. “Thankfully, we got through it as a team, as we always do. I’m particularly proud of the exemplary communication shared between all team members—it’s continued to be a major contributor to our success up to this point in the project.”

Since the topping out celebration doubled as a Safety Week event, Justin took the opportunity to also share his personal insights on what it means to Speak Up for Safety and foster a safe work environment for all.

“When team members truly respect one another, help one another, communicate with one another, and commit to positively contributing to the project site, it culminates in a job site that everyone looks forward to showing up to every day,” he says.

Since topping out on April 27, the team has hung the exterior glass fiber reinforced concrete (GFRC) and framed and sheetrocked the level 1 interior priority rooms. Currently, they’re aligning and welding the GFRC and framing level 2 with plans to begin framing level 3 this week. They plan to be temporarily watertight to start hanging sheetrock throughout the building on June 2 and expect to receive their temporary certificate of occupancy (TCO) by March 11, 2024.

Once complete, CCC ADR will comprise a newly built 3-story administration building and outdoor plaza featuring salvaged granite blocks from the historic Contra Costa County Jail built in 1904, which are being repurposed as seat walls and paving throughout the new public plaza; salvage and reuse of perforated wood panels taken from the original administration building built in 1962; and salvage and reuse of marble wall panels taken from the original administration building in 1962.

The new administration building will feature office spaces for various public work entities, including the Contra Costa County Sheriff’s department, Contra Costa County Television department, and the Contra Costa County Law Library, and the outdoor plaza will be used for community events such as farmer’s markets and public performances.
