Projects by O’Donnell & Naccarato Structural Engineering Firm in Philadelphia
We take great pride in our work at O’Donnell & Naccarato, providing innovative technology, design, and excellent structural engineering services to our clients and communities, both national and in Philadelphia. Below are just a few of the projects our structural engineering firm in Philadelphia has worked on.
Loews Philadelphia Hotel, locally known as the PSFS Building, is a skyscraper in Center City, Philadelphia, Pennsylvania. A National Historic Landmark, the building was the first International-style skyscraper constructed in the United States. The hotel sits in a prime Center City location, surrounded by the Pennsylvania Convention Center, Chinatown, the Avenue of the Arts, and many more historic and cultural landmarks.
O’Donnell & Naccarato’s structural engineering firm in Philadelphia performed a façade assessment of the skyscraper that included the steel-framed antenna extending above the roof in 2017. Our team of certified rope access engineers were able to investigate the skyscraper up-close while not disturbing the daily operations of the hotel. Following our investigation, we were contracted to address deteriorating limestone, brick masonry, corroded steel framing, sealants, and to provide flashing improvements.

Parkade On 8th
O’Donnell & Naccarato provided structural engineering design and restoration services to repair, modernize, and beautify the 6-story, 1,200-space parking garage, and 30,000 SF of ground-level retail space. Improvements included repairs throughout the garage, and more noticeably, significant aesthetic renovations to dramatically alter the building’s exterior appearance. On the North elevation, screening with colored glass louvers that shimmer and reflect light add visual interest while helping to obscure the structure’s decks. Learn more about the project here.
