Yavapai Point Museum

National Park Service
Grand Canyon National Park, Arizona

Based on results from previous work assessing the potential seismic hazards of a large number of structures in the Grand Canyon National Park, this facility was selected for an in-depth evaluation and rehabilitation. JFSA provided on-site investigation, extensively measuring, inspecting, and documenting the current conditions of this historic building. Structural rehabilitation solutions and cost estimates were prepared and incorporated into the Architectural rehabilitation of the building.

Project Highlights:
  • Assessment of an unreinforced stone masonry structure located on the rim of the canyon and constructed in 1928
  • Provided on-site service to assess current condition and evaluate the anticipated seismic performance based on FEMA reports 273 and 310
  • Design horizontal and vertical rehabilitation of existing structure, including roof, walls, and foundation
  • Follow the Secretary of the Interior’s Standards for Rehabilitation
