CA Emergency Ops Center & Welding Hydraulic Door

When officials entered the planning phase for the construction of Contra Costa County’s new Public Safety and Emergency Services (EOC) building in Martinez, California, it was decided to look for one of the hydraulic structural doors at Schweiss Doors.

The new public safety building and emergency center is equipped with the latest in disaster management and public safety technology. The sheriff’s administrative, tax, personnel and emergency services are also located in the building. The 40,111 square meter building is designed in such a way that it can be operated independently for up to a week in the event of a natural disaster or a crisis in which municipal utilities no longer work or are no longer available.

Contra Costa County selected the Hensel Phelps Construction design-and-build team of Irvine, California to complete the project. Dreyfuss + Blackford Architecture, with offices in Sacramento and San Francisco, contributed to the design and oversaw the construction of the two-story building, which was jointly designed by Ross Drulis Cusenbery Architecture of Sonoma and Emeryville, California.

The custom hydraulic glass welding designer door is 23 feet, 1 inch wide and 13 feet, 9 inches high. It is equipped with electric photo eye sensors, a door edge safety edge and a hydraulic reserve system in the event of a power failure. The hydraulic pump was hidden in a remote location about 30 feet from the door. A decorative lattice canopy extends outward and over the door, uniquely reflecting the glass door and sidewalk below.

The new essential service facility houses the county sheriff’s office and command staff. A state-of-the-art emergency room within the EOC is equipped with the latest communication technology. Inside the building there is a public training and lecture hall with facilities to support media discussions in times of emergency operations and community events. The building was designed to receive LEED Gold certification with a score of 62 points. Further points are still pending.

“A structural aspect that is unique for this building is the use of the ConX Tech Chassis-based Modular® building system,” says Julian Andrade, architect and project manager at Dreyfuss + Blackford. “It has a bolted collar system for structural bracing inside the building, so there are no chevrons or transparent walls. It’s an all-in-one built-in system that doesn’t require an additional X-bracket. The use of ConX was probably canceled a few months before the scheduled date. It was a very quick project and we had a great team to work with.

Jim Robinson of Arktos Inc. of Castro Valley, California placed the order for the hydraulic door. “The hydraulic door is essentially used by the sheriff’s office,” he says. “This special room is designed for multimedia devices so that you can set up your camera on an adjacent terrace in the event of a disaster.”

Arktos is part of the Security System Services industry that sells, installs, and services door gate and barrier products that enable customers to protect their physical perimeter and control access to these areas.

“We understand hydraulics because we do a lot of hydraulics,” says Robinson. “The welding door is a well designed and impressive door that is well thought out and looks great.”

Andrade said the building is a huge improvement over the previous county and Dreyfuss + Blackford really enjoyed working with the client and Hensel Phelps on the project.

“The county is very happy with the building and the door,” says Andrade. “We didn’t have much to do other than prop up the door. The lecture hall has a retractable stage at one end that slides into a vertical position that is built into the wall. The hydraulic door at the other end opens to an outdoor courtyard. It offers space for 160 people indoors and a further 140 people outdoors. Outside there is a press area where trucks can be hooked up. It could be used for award ceremonies, educational purposes, public interaction. It’s kind of a large multipurpose room. “
