Case Study: University of Pennsylvania resolves severe façade water infiltration with Thornton Tomasetti

University of Pennsylvania replaces 100% of window head flashing with Thornton Tomasetti before fall semester

The University of Pennsylvania faced severe water infiltration issues at its McNeil Building, a 1970s academic facility. They engaged the engineering firm Thornton Tomasetti to perform a façade investigation to diagnose the problem and provide recommendations for rehabilitation.

Thornton Tomasetti's investigation identified failed window head flashing and limestone sealant joints as the primary causes. The vendor was re-engaged to produce repair documents and provide construction administration, successfully overseeing a complete replacement of these elements on a tight schedule between semesters. The solution by Thornton Tomasetti resolved the water infiltration and restored the building's façade.
