42 Trinity Place / 77 Greenwich Street

overview

Rising 500 feet in New York’s Financial District, this graceful, stepped glass tower features a mix of residential, retail and educational programming. The tower’s unique serrated shape allows all 90 of the high-end residences to enjoy views of the New York Harbor.

We provided building envelope consulting services to Trinity Place Holdings and collaborated with architect, FXCollaborative, for this 42-story, 300,000-square-foot mixed-use development comprising residential space, a public school at the podium and retail on the ground floor and one grade below. The building occupies two thirds of the city block bordered by Rector Street, Trinity Place, Edgar Place and Greenwich Street. The project also includes the gut renovation of an adjacent landmark building, the Dickey House.

highlights

• The podium’s façade consists of UHPC cladding with punched windows installed as a unitized curtain wall system.
• The tower façade consists of a similar UHPC cladding system along the east elevations and a glazed unitized curtain wall on the west elevation, with views towards the Hudson River.
• Thornton Tomasetti’s scope included design consulting and facade engineering, development of facade details and specifications, bidding, submittal reviews and construction administration with façade special inspections.
• One of the project goals was to attain the NYC Zone Green deductions by exceeding code-required façade thermal performance. To achieve this, our engineers assisted in the design, detailing, specifications and analysis that resulted in gaining additional square footage in the building.
