730 Fifth Avenue
New York. NY
GMS provided structural engineering for the extensive redevelopment of the retail portions of the Crown Building, located at the corner of Fifth Avenue and West 57th Street. This multi-phase project included the structural design necessary for the relocation of the building lobby, the upgrades associated with all egress changes and mechanical upgrades for the building conversion, and the redesign for multiple high-end retail spaces along 56th and 57th Streets and along Fifth Avenue.
All structural work took place while simultaneously upgrading the existing building super- and substructure for the design of a 20-foot-wide cantilever working platform with a capacity of 300 psf, for the upper unit Owner. This will provide retail tenants a column-free sidewalk while protecting pedestrians of these heavily trafficked blocks during the building renovation. The reinforcement of the building perimeter columns, existing framing, and lateral system were integrated into the multiple retail tenant fit-outs.
