With its distinctive saw-toothed exterior, this housing facility will serve low-income seniors, providing a building with energy efficiency and seismic safety in mind. Forell Elsesser provided structural engineering services for this 9-story, 101-unit apartment building with underground parking for 26 vehicles. The housing provides 57 studios and 44 one-bedroom apartments for low-income seniors as well as community, retail, and dining space on the ground level.
Customized Solution
- The saw-toothed exterior of the building created structural variability which required careful detailing of the post-tensioned slabs to maintain gravity and seismic stability.
 - Site soil improvement was required to limit seismically induced settlement and secure the mat foundation.
