Federal Building, San Francisco

Location: San Francisco, CA

Project Type: Peer Review/Plan Review

Structural/Seismic peer review of San Francisco’s new federal building, designed by Thom Mayne. The new high-rise concrete frame/shear wall tower building includes two large steel braced frame ancillary structures and an underground parking garage covering the entire site. The structural design was unique in that the aspect ratio of the shear walls in the office tower was nearly 10 to 1. Arup was the engineer of record. [With Degenkolb Engineers]

Portola Valley

Architect: 2M Architecture

Contractor: Matarozzi Pelsinger Builders

Located just over 1 mile from the San Andreas Fault, FTF was tasked with finding a superior solution to the “Life Safety” standard required by the Building Code. FTF combined advanced seismic analysis with state of the art building technology to create one of the most seismically resilient private homes in the United States.

The house takes full advantage of a dramatic site, with rooms opening to the outdoors and, taking full advantage of the view and natural light, high-lighted by a deck, cantilevered high above the ground and oriented towards views from San Francisco to San Jose.

Interior Tenant Improvement

The building was constructed circa 1936, and consists of perimeter concrete walls, wood truss roof framing with 1 x 6 straight and diagonal sheathing and rod bracing that support the concrete walls out of plane. Tenant improvements include new metal stud framed partitions, steel stairs, steel framed stadium seating, and mezzanine alterations.

The project involved restaurant tenant improvement of an existing 2-story rectangular wood framed commercial building located at 8055 West 3rd Street in Los Angeles. The work included significant alterations to the existing mezzanine, creating an open dining environment and exposed structural steel framing above the kitchen and circulation areas. The building previously underwent a seismic upgrade consisting of the addition of a single bay moment frame along the street-facing facades of the building.
