Silman also worked closely with the façade consultants to fine-tune the cable system and support structure for the glass cable wall system in the ground-level lobby. Silman designed the lateral connections with redundancy to support the full weight of the panels above. The building façade consists of glass, precast panels, and steel panels, with the precast and steel panels hung from the top and braced laterally at each floor. ![]() This allowed the contractor to estimate expected building movement during installation. To aid the façade contractor in the development of details, and to facilitate construction sequencing and schedule, Silman provided deflected-shape diagrams and deflection values at critical points. The absolute deflection of the building’s long-span beams and full-story trusses was significant in some locations. To achieve these 25- to 80-foot-long cantilevers, Silman used a full-story truss that spans along the south side of the gallery and is supported from perpendicularly spanning two-story trusses. The structure’s upper stories transfer at the column-free fifth-floor gallery, which cantilevers in two directions over the lower levels. The galleries and open offices left limited locations for the lateral braced frames, introducing discontinuities in the load path such that most building elements were designed for overstrength. Silman used steel to achieve the design’s long spans and open plan galleries. On the top floor, a sawtooth skylight system provides natural light for the “studio” gallery and a café.Ĭomposite steel framing with concrete on metal deck slabs was used for the superstructure. To the south, the building cantilevers dramatically over a public plaza, creating a set-back entrance that opens into a 10,000-square-foot lobby with a free-entry exhibition space.Ībove the lobby, spaces include a theater, offices, and expansive new galleries. The asymmetrical nine-story building features tiers of terraces and glazed walkways that step down to the High Line. The architect for the project was Renzo Piano Building Workshop, Cooper Robertson. The new building in Manhattan’s Meatpacking District was commissioned to better showcase the Whitney Museum’s extensive collections and to provide additional programming space.
