Work on the University of Virginia McIntire Amphitheatre started out as a roof replacement and cosmetic touch-up, but has evolved into structural repairs.
“The project started a couple years ago, and we were going to remove the failing coating that was put on in 1994 over the original stucco, replace the roof and do a little groundwater work in the yard,” project manager Amy Moses said. “When we took off the coating, we started to notice we had problems.”
Removing the stucco coating, which had been applied to cover cracks in the plaster, revealed structural issues caused mostly by the shifting and settling of the fill underneath the building. Workers are now anchoring the building so that bedrock becomes the building’s stabilizing point instead of the fill. Braces were erected around the amphitheater wall to stabilize it while the work was being done.

“We installed micropiles – basically a screw that goes down into bedrock – to which we attach the concrete beam,” Moses said.
The amphitheater is not like other structures on the Grounds. Designed by Fiske Kimball, UVA’s first architecture dean, it was completed in 1921 as a gathering place larger than any then-existing University building.
“The whole building is constructed out of terra cotta blocks,” Moses said. “Some of them have grout; some don’t. Most of it doesn’t have rebar where original drawings call for it, but we did find some rebar that we hadn’t found during our probes. The blocks themselves are fine, except for where the building has moved, and that’s where you see the cracking radiating through.”
