Philadelphia, Pennsylvania

Structural engineering services for a 150 room hotel, fourteen story structure located on an urban site.  The building superstructure consists of steel-framed composite slabs and girder slabs with steel columns.  Concentric and eccentrically steel braced frames comprise the building lateral system.  The below-grade structure consists of a tall, one-story level of parking to accommodate triple car parking lifts, with 24′-0″ tall concrete foundation walls and a mat foundation slab beneath the entire building footprint.  Above-grade levels include a ground floor for retail, hotel lobby and back-of house spaces, a second floor for meeting and fitness room with an indoor pool, and twelve guestroom levels.  The new hotel tower is to be constructed on a site occupied by an existing, two-story historical structure.  This existing structure is to be demolished, but the existing Art-Deco facade on two sides is to be braced during construction and incorporated into the new hotel design.
