Sidney Hillman Apartments Parking Garage

Location: Philadelphia, PA

O'Donnell & Naccarato provided structural engineering and construction administration services for the restoration of the 3-level, 24,400 SF, cast-in-place concrete parking garage. The 1-level above and 2-level below-grade structure is located beneath 16 stories of residential space. Following O'Donnell & Naccarato's condition assessment of the existing structure, an observation report and detailed repair recommendations were developed. Repairs included full-depth replacement of the concrete parking deck, concrete overhead repairs, vertical repairs, and the installation of an epoxy waterproof coating to the top level.

During construction, O’Donnell & Naccarato maintained a full time presence on-site to accommodate the desired construction progress schedule. As requested by the owner, daily field reports and weekly progress reports were generated.
