Audiffred Building
Seismic Evaluation & Upgrade
San Francisco, CA
Interactive Resources provided structural engineering consultation during the seismic reinforcement of this 25,000 square foot, four-story commercial office building.  The upgrade involved reinforcement with unreinforced brick exterior walls, wood floors and roof framing, and timber pile foundation. The original building was constructed before the 1906 earthquake.

The building was severely damaged by fire and was an idle ruin before rehabilitation. Demolition was problematic due to the instability of the existing structure. The Audiffred Building is noted on the National Register of Historic Places.
