This curtain wall is a retro fit onto an existing building with an exterior masonry wall on the other facades. This facade faces north onto the East River with views of the Manhattan skyline across the river.

The primary structure of the existing building is steel, but the installation of this curtain wall requires extensive modification, including new concrete piers and welded steel plates set at angles to the line of the building frame. This view also shows one worked sawing the existing steel in preparation for the new anchoring system.
