Jacksonville U.S. Federal Courthouse

This new federal courthouse, designed by HLM Design/KBJ Architects is a fourteen-story-high reinforced concrete building of approximately 420,000 gross square feet, including 82 parking spaces in the lower level. The new $84 million courthouse facility houses the following agencies: U.S. District Court and Clerk of Court, U.S. Magistrate Court, U.S. Marshals Service, U.S. Attorneys office, U.S. Probation office, and non-court related Federal agencies.

As part of the review process, we performed non-linear dynamic computations to evaluate the maximum displacement response and reaction loads.

The tasks we accomplished as part of the design included:

  • Progressive collapse design analysis for the building frame
  • Hardened floor, column, and wall designs for the underground parking area, loading dock, and lobby
  • Preliminary blast resistant designs for the exterior wall and window system
  • Design of a barrier system for the perimeter to resist the threat of a ramming vehicle

As a consultant during the construction phase, we reviewed the shop drawings and calculations prepared by the precast and curtain wall subcontractors, ensuring that these elements fail in a low-hazard manner for a specified exterior explosive threat. As part of the review process, we performed non-linear dynamic computations to evaluate the maximum displacement response and reaction loads.
