Seismic Assessment and Rehabilitation

Structural Assessment and Historic Building Rehabilitation

Building 210

Gateway National Recreation Area

With plans well under way to place a number of large new air conditioning units on the roof of this building, there were some alert to structural integrity of the roof. JFSA investigated building 210 to assess the structural implications of the proposed installation along with the general condition of the structure.

Project Highlights:
    JFSA worked under a number of constraints, including:
Structural Assessment and Historic Building Rehabilitation
Ranger Operations Historic Building Rehabilitation
Seismic Rehabilitation Makah National Fish Hatchery

Ranger Operations Historic Building Rehabilitation

Grand Canyon National Park, Arizona

JFSA provided screening and structural evaluation of the Grand Canyon National Park's historic ranger operations building.

Project Highlights:
  • Originally constructed around 1929 of light wood framing and stone masonry
  • Vertical and lateral analysis
  • Gravity analysis

Seismic Rehabilitation Makah National Fish Hatchery

Neah Bay, Washington

The U. S. Fish and Wildlife Service identified their Makah Hatchery, near Cape Flattery at the extreme northwestern corner of the contiguous United States, as being potentially hazardous during a seismic event. JFSA was requested to visit the site, investigate the structure, perform a detailed seismic evaluation, and design retrofits to mitigate these hazards.

Project Highlights:
  • Building type, two-level reinforced masonry structure
  • Geotechnical Investigation
  • Cost Estimates
  • Construction Drawings
