The polished precast concrete exterior was chosen to set it apart from a glass façade. The precast concrete material features marble and sandstone chips in various colors that reference nearby buildings. The GateStone polished finish simulates terrazzo and improves on the appearance of the mosaic material, while Gate Precast’s new system of sequential casting adds to the authenticity.
The genesis of the polished façade began with a request from DCA for precast concrete samples from Gate Precast. Critical to the job was the ability to provide a polished finish on the face as well as on the returns, and keep the same consistent finish around the corner. This is a dramatic difference from an architectural precast concrete panel that is finished on one side.

It was critical to get the product to the site on time to use the crane efficiently and to make the piece count needed to meet the 120-day install schedule. The precast concrete—more than 1237 pieces and 90,000 ft2—was shuttled to the site each night as needed.
