KPFF is providing structural engineering services for this 3-phase project. Work includes the design of a seven and nine story office building and two parking garages. The office buildings are 340,000-square-feet and 285,000-square-feet and constructed with precast concrete columns, beams and exterior cladding. KPFF utilized an innovative precast hybrid moment frame and concrete shear core to resist lateral forces.

The hybrid moment frame serves a dual purpose as the perimeter lateral bracing system and exterior cladding systems. The hybrid frame was developed to sustain high building drifts, while exhibiting high ductility and minimizing structural damage. Because this project is located 2 km from the San Andreas Fault, the seismic performance of this project was a key design issue.

The Phase 2 parking garage is 7 stories and 265,000-gsf, while the Phase 1 parking garages are 3 garages and 8 stories and total 560,000-sf. Each garage is constructed with precast concrete columns and beams, and utilizes concrete shear walls to resist lateral forces. KPFF provided the design detailing and calculations for all aspects of this project including the precast columns, beams, spandrel panels, and hybrid moment frame system.
