Brooklyn Post Office

This 600,000-square-foot courthouse and post office was built over the course of two campaigns: an 1892 granite building and a 1933 addition that tripled the original footprint. TYLin's first exterior envelope project at the building involved limited design of repairs to the terra cotta facade. More recently, TYLin collaborated with the architect on documentation of existing facades, development of options for repair and replacement of terra cotta cladding, peer review through the GSA’s Design Excellence Program, production of construction documents on an accelerated schedule, and construction phase services.

TYLin’s work included the design of repairs for the steel shelf angles, spandrel beams, and columns; the steel and structural hollow tile roof and floor framing in the 1892 building’s tower; the 1933 building’s concrete roof framing; and the interface of the 1892 building and 1990s courtyard infill. TYLin also reviewed the possible effects on the structure of a new work positioning and fall protection system and conducted regular site visits to observe progress of construction and respond to field conditions.
