The one-story Analytical Laboratory building is located on the Materials and Fuels Complex at Idaho National Laboratory (INL). The building is a concrete and masonry structure with a high bay that houses an overhead crane. INL was concerned about meeting Performance Category 2 (PC-2) requirements for the Analytical Laboratory. SGH evaluated the facility and designed modifications, applying structural, building technology, and civil engineering capabilities to meet new requirements.

Scope | Solutions

Our work for this project included the following:

Structural evaluation and upgrade design of the Analytical Laboratory for PC-2/Seismic Design Category 2B (SDC-2B) compliance. Upgrades include the following:
- Roof structure above the existing laboratory roof
- Roof bracing and anchorage above the existing crane bay
- Exterior strong backs to support walls and resist wind uplift
- Basement wall bracing to resist soil loads
- Exhaust stack upgrades designed for static and dynamic wind effects
- Removable hot cell door restraints for seismic resistance
Fire protection and weatherproofing design at new roof and new structural components
Civil design of lightweight fill, drainage, and asphalt pavement to reduce lateral soil pressures
Preparation of calculations, design drawings, and specifications that were independently reviewed and accepted
Development of three-dimensional visualization to aid work planning and coordination with laboratory operations
Construction administration and contractor support
