Calvary Presbyterian Church, Seismic Upgrade, San Francisco, California

Degenkolb performed a seismic evaluation and implemented strengthening for this 1901, unreinforced masonry (URM), Sanctuary Building at this historic, San Francisco church. The building consists of two stories plus a basement, and the sanctuary is one tall story with a basement, totaling 31,700 square feet. The strengthening was designed to meet the State Historic Building Code and the Uniform Code for Building Conservation, to comply with the San Francisco URM Ordinance. The strengthening scheme creatively fit within the building’s historic fabric, virtually invisible following construction. The project also included an elaborate architectural remodel, creating structural challenges; the removal of an old staircase and addition of a new one, the extension of the elevator to serve the basement level, and the creation of an exposed brick lobby. The church remained fully operational during construction, and the City’s second largest pipe organ remained untouched.
