Our Role

BRC design included architectural acoustics and mechanical noise control for courtrooms, judge’s chambers, law library, reading room, and other critical spaces. Traffic noise was monitored and evaluated for interior noise impacts due to the proximity of city street and freeway traffic. The project included security enhancements, restoration of courtrooms and interior spaces, modernization of electrical and mechanical systems, as well as seismic upgrades.
