181 Fremont

Located in the heart of San Francisco’s financial district, this 54-story mixed-use skyscraper offers Class-A office space and residential condominiums within a striking architectural form. The building’s shimmering floor-to-ceiling glass curtain wall wraps around its façade, creating a bold and iconic presence. An elegant spire crowns the tower, bringing its total height to 800 feet and stands as a prominent addition to the city’s skyline. Larson Engineering, Inc. was proud to contribute to this landmark project by providing the structural engineering for the saw-tooth curtain wall and diagrid panel systems. The building’s complex geometry, combined with high wind and seismic demands, presented a rewarding engineering challenge—one that required creativity and close collaboration to bring the architectural vision to life.
