Fort Point National Historic Site
Client: Denver Service Center and Pacific West Regional Office, National Park Service
Golden Gate National Recreation Area, San Francisco, California
Background and Issue
Fort Point, built between 1853 and 1864, is the only Civil War-era fort on the West Coast. Based on a French system, it is a Third System Fortification. Besides its military history, the fort is also significant because of its exceptional masonry workmanship. The fort is located in a very harsh micro-climate. Situated on a peninsula between the Pacific Ocean and the San Francisco Bay, it is surrounded on three sides by salt water. The west side of the fort is often pounded by waves. Fog regularly engulfs the fort with salt-laden mist. Paint and debris fall from the Golden Gate Bridge above it.
We completed numerous projects at the fort, including (1) an investigation of water leakage at the top tier of the fort that was causing damage to the brick casements below; (2) an investigation of the original storm water catchment system and cisterns; (3) preparation of waterproofing and masonry repair alternatives that were evaluated in a value analysis workshop; (4) additional documentation, including color conditions photographs, HABS photographs, 35-mm black-and-white photographs, and 3D laser scanning which we used to create a Revit model; (5) an investigation and repair alternatives for the damp rise issues along the west and south walls; (6) repair of doors and replacement of shutters; and (7) replacement alternatives for the cast-iron embrasures.
Heidi Y. Granke was the project manager for these projects while at Architectural Resources Group.
