Roseville City Hall

USRC Statement  

The City of Roseville had outgrown its city hall building and because of a lease signed with Sierra College to begin classes in January 2017, city planners had only 12 months to design, program, build and prep the building for occupancy. Other building systems had been explored, including steel and cast-in-place concrete, but the Precast Hybrid Moment Frame system was decided on because it gave the architect design flexibility for this prominent building that sits in the Roseville City Square.  Also, the 4-story office building houses critical operations for the city and in the case of an earthquake city officials needed the reassurance that these mission critical services would be housed in a safe, resilient structure. The design achieved these goals by obtaining USRC 5-star ratings in Safety, Damage and Recovery.

Innovative Structural System Yields High Performance 

The city office building’s original design called for a steel structure with a plaster finish. However, the City selected the Precast Hybrid Moment Frame because it gave the architect flexibility in the design, met its tight delivery requirements and provided the City with reassurance that during an earthquake, critical operations and services would be housed in a resilient structure.

The platinum rating is the highest rating from the USRC.

  • It predicts the consequences of an earthquake on a building and projects the performance of the structure during the event, as well as the cost and time of structural recovery and repair. 
  • The PHMF structural system incorporates a high-performance precast hybrid moment-resisting frame that limits design level drifts to less than 1.25 percent. 
  • The system is designed to be self-centering after the seismic event eliminating residual drifts, limiting damage, and providing for reduced recovery time.

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.

City of Roseville's Statement

“The City of Roseville is extremely pleased with the project outcome. Publicly-funded projects of this size, scope and complexity are rarely, if ever, completed in the timeframe of 316 Vernon, due in significant part to the precast design and innovative just-in-time construction methods. Other added benefits from an operational perspective include: lower long-term maintenance costs, superior sound isolation / exterior noise suppression, and approximately 30% less energy consumption attributable to heating and cooling as a result of the building’s efficient thermal mass. As the owner and occupant, we couldn’t be happier.”
