Residential Seismic Upgrade

We provided residential seismic upgrade designs and engineering services for a older 3 story plus daylight basement residence located on a steep hillside in Portland’s West Hills. Our client recently purchased the house and was concerned by the large portions of existing brick foundations. We worked closely with our structural engineer to develop a system that would best adapt to the existing conditions. A new footings were poured inside the existing crawlspace walls and new shear walls added to the interior. Floors and walls were tied together and interior structural sheathing added to upper floors in determined locations.
