Our Philadelphia Headquarters Office Has Moved to Market East
Our new Philly office location is 701 Market Street, Suite 6000, Philadelphia, PA 19106 in the historic Mellon Independence Center. Like much of Center City Philadelphia, the Market East neighborhood is in the midst of a revival, and our new location places us squarely in the heart of the action. As structural engineers and residents of Market East, we look forward to contributing to its continued growth, development and prosperity.
Our history with this historic landmark:
Mellon Independence Center, originally known as the Lit Brothers Department Store, is comprised of 13 unified buildings constructed between 1853 and 1907. In 1979 the building was added to the National Register of Historic Places. In the late 80’s O’Donnell & Naccarato helped restore the aging cast-iron structure and Renaissance Revival-style facade when O&N’s longtime client, Brickstone Realty, converted the building into commercial and office space primarily for Mellon Bank (hence the center’s new name). The firms’ recent collaborations at Mellon Independence Center include the design of new rooftop LED displays.
