1800 K Street

1800 K Street is a commercial office building located in the heart of downtown Washington, DC. For this repositioning project Forrester Construction renovated the central chiller plant while the building remained fully occupied. A new high-performance building skin will be installed during a subsequent phase of work.

During the first phase of work, the two main chillers were replaced with new frictionless centrifugal units. In the planned second phase of work, the building’s existing curtainwall and precast concrete façade will be removed and an all glass system will be put in place. On the ground level, a glass storefront will be installed and sidewalk and hardscape improvements will be made. To enhance the building’s high-end appeal, a penthouse terrace will be created and the main lobby will be renovated including elevator and finish upgrades.

Forrester made extensive use of a 4D progression model to coordinate the second phase of work. In addition to assisting with scheduling and planning, the model illustrated to the owner as well as current and future tenants the sequence of work and building access during construction.

1800 K Street is expected to earn LEED™ EB Silver certification thanks in part to the chiller plant upgrades made as part of this project.
