Three consultants with historic preservation, architectural and structural engineering expertise were contracted to conduct a structural assessment of the Grant County Courthouse concrete slab floors. They collected and analyzed data through a detailed visual survey of the floor slabs, materials testing using non-destructive methods and performing engineering analysis. Recommendations were made for the retrofit of the floor slabs.
Two options were identified in the report. It was decided to use a combination of the two options, selecting the least adverse treatment for each interior space depending on the needs for the space.
