Walbridge joint ventured with Overaa to design-build the $22.8 million Army Reserve Center (ARC) in Concord, Calif. The project include construction of a 68,000-square-foot training and storage facility, 9,500-square-foot organizational maintenance shop, 4,000-square-foot unheated storage building, parking lots and supporting utility installation.
The new ARC was designed and constructed to meet LEED® Gold certification through the U.S. Green Building Council’s Leadership in Energy and Environmental Design.
The new Concord ARC features an 87,000-square-foot photovoltaic field, which generates about 465 kilowatts of electricity that’s directly tied into the new training and storage building’s electrical system. During the day when it’s generating power, the PV field offsets power being used at the building. Energy generated during the day that’s unused is pushed into the power grid, which generates energy points with the local electricity provider and lowers the USACE’s energy bills. The massive PV field is made up of 2,300 panels.
In addition, Walbridge | Overaa installed a state-of-the-art rainwater storage system that’s used for the ARC’s vehicle washing. The system has a capacity of 120,000 gallons
The Walbridge | Overaa Joint Venture broke ground at the site in October 2011 and wrapped up in March 2013. In more than 147,000 hours logged at the site, the team recorded zero lost-time incidents.
