Nibbi Brothers was awarded the contract to perform the structural upgrade of this historic Church, which was damaged in the 1989 earthquake. The seismic upgrade work includes new structural steel cores which extend into the attic, new foundation concrete in the basement and new structural concrete walls in the auditorium. The main shear cores are composed of structural steel and shotcrete and will be epoxy dowelled to the exterior of the church. Additional work includes re-roofing, upgrades at the altar and pews for ADA compliance, re-painting the interior and installing new fire sprinkler service. The church will remain in service throughout construction.

This historic Church was dedicated in 1854 and is designated San Francisco Landmark #2.
