Roseville City Hall Annex

Roseville, CA

As the first ever building rated by the United States Resiliency Council (USRC), the Roseville City Hall Annex takes sustainable design to a new level. The fully precast concrete structure utilizes long-span  double-tees at each floor to maximize open space. Precast Hybrid Moment Frames utilized on the project are not only a high performing structural system but by featuring these as the exterior skin it results in an incredibly efficient design. The frames, which are self-righting, are designed to allow the building to be occupied immediately after a seismic event which was a major contributing factor to the building achieving a platinum rating,  highest rating possible from the U.S. Resiliency Council.
