PARK 79 steel detailing / temporary shoring
117 W 79TH STREET, NEW YORK, NY
The original seven-story building on the Upper West Side opened as ‘The Indiana’ in 1888-1899 and was designed by New York architect Neville & Bagge in the Renaissance Revival style, with a brick and stone façade and an elegant front entrance. In more recent years, the building was known as Park 79, an extended stay, single room occupancy hotel, which was closed in 2015.
The original terracotta flat arch floors are supported by steel beams and reinforced with steel tie rods. The beams bear on perimeter brick bearing walls and on interior steel beams and cast iron columns columns and brick walls surrounding a lightwell. The structure was deteriorated and the integrity of the arches was partially compromised during previous remodeling projects. The extensive structural work included restoring the structural integrity of the slabs and facade rehabilitation, new stairs and elevator with bulkheads, new openings in slabs and exterior walls, floor infills.
Madsen provided a full range of services for this project - besides being the Engineer of Record, Madsen also provided temporary shoring design and sequence of demolition and construction, as well as structural and miscellaneous steel shop drawings and connection design.
