Base Building

Washington, DC |7,000 sf

The 1400 Eye Street façade and lobby project included a new curtain wall system, replacement of the ceiling above the McPherson Metro stop, complete renovation of the lobby finishes, infrastructure and new elevator cab finishes.  All of this was completed while maintaining access to the building and the Metro stop.


The new curtain wall system was constructed outside of the original building footprint to maximize the floor space and to allow for watertight conditions during construction. The new system was located approximately four feet from the existing but at areas was as close as four inches.   In order to maintain the integrity of the building envelope, temporary enclosure systems were constructed and phased to maintain security while allowing for construction progress.


The lobby work was phased in order to maintain public access and provide a partitioned construction zone for the work areas. The entire sidewalk was covered in a scaffold deck structure to allow for the metal panel ceiling system to be installed over and on top of pedestrians as well as the Metro escalator. The elevator cabs were also completely refinished in a phased sequence to minimize impact on tenants.
