GMS is excited to be working with Tishman Speyer, providing Building Envelope Consulting Services for the development of a new condominium residential development at 11 Hoyt Street in Brooklyn. The building consists of a 57 story tower, approximately 770,000 sf, which rises to a height of over 600 feet with one cellar level below grade, and a green roof above a two
–story podium. The tower houses 481 apartments with over 55,000 sf of amenity spaces.
GMSFacades has worked with Studio Gang and Hill West Architects to develop the drawings, details, and specifications for the “scalloped” precast concrete façade panels, as well as the windows and the waterproofing. Approximately 1155 precast concrete panels were produced by Bétons Préfabriqués Du Lac in Alma, Quebec, Canada. Custom aluminum window systems fabricated by Pichler, Steel Structures & Facades, Bolzano, Italy, were installed by BPDL in the factory. In total, over 110,000-square-feet of glass, produced by Guardian Glass and fabricated by Tvitec, Leon, Spain were used for the project.
A particular challenge was waterproofing associated with the exposed horizontal sections of the precast panels. “The waterproofing had to be applied at the BPDL plant to avoid costly and difficult installation in the field and it had to be done immediately at the time of production without disrupting BPDL’s plant workflow,” said GMS Partner Achim Hermes. “Due to winter weather restrictions in Alma, Quebec from October to April, the application of the waterproofing had to be done indoors. That meant it had to occur shortly after the precast panels were stripped out of their forms.” GMS worked together with Soprema, the waterproofing system manufacturer, and BPDL to find the best product for this application to would meet the specific constraints.
Our team worked with the Architects and the Developer from the beginning of the design process and performed inspections and quality reviews throughout the construction phase. These included factory visits, mock-ups, and many inspection “drops” from suspended scaffolding. Reflective glass provides the added benefit of a selfie, and the team occasionally takes a moment to show off the amazing views!
