2101 Connecticut Avenue Cooperative Apartments

Washington, DC

This property consists of 64 condominium units housed within a nine-story cooperative building located in a historical district in downtown Washington, DC. Original construction was circa 1920.

The building facade is constructed of brick masonry and decorative terracotta stones with custom cast stones such as archways and gargoyles. Non-insulated hung windows were single pane with storm windows. Guest rooms and common area windows were replaced in 2004-2005 with new Trimline windows (with two operable sashes) constructed of wood with aluminum on exterior and insulated glass. Some units received laminated glass due to outside noise. A total of 1,670 windows were replaced in the building after being approved by a historical society.

The existing roof was an EPDM membrane over a reinforced concrete one-way slab/joist system. Leakage into individual cooperative apartments was becoming more widespread and the owner asked TCE to evaluate the roof and develop a replacement solution. TCE prepared a condition survey report and cost estimate for the roof. TCE developed replacement specifications for a hot-rubberized asphalt membrane in an IRMA configuration with a 20-year warranty. TCE handled all aspects of the project for the owner including bidding and contract negotiations, and quality assurance and contract administration during construction. As this is a residential building, extensive planning and coordination with the roofing contractor, residents, and the cooperative board of directors was required, all of which was spearheaded and coordinated by TCE. The roof area was approximately 24,000 gsf. The presence of rooftop decks and terraces added a degree of complexity to the project which was overcome through meticulous detailing of the drawings and planning during construction.
