PRV Stations and Water Heaters Replacement, Longworth House Office Building

The Architect of the Capitol (AOC) has a requirement for construction services for the removal of unused water tanks and hot water tanks, the removal of the existing pressure reducing stations and condensate tank, and construction of new pressure reducing stations and condensate tank, all within the same mechanical room in the Longworth House Office Building (LHOB) in Washington DC. Steam service entering the building will be connected to the new construction (steam service leaving the room) and old piping and equipment will be demolished.

The Longworth House Office Building (LHOB) is an eleven-story office building. The building provides office space for the U.S. House of Representatives and their staff, and meeting rooms. The attic, ground floor, and the sub-basement and basement floors also contain several storage rooms, electrical rooms, and mechanical rooms. In addition to offices, the basement floor also contains a cafeteria with a kitchen, food carryout and a credit union. The building is considered a business occupancy.

The existing steam pressure reducing valve (PRV) stations serving the air handling units (AHU) and kitchen/domestic hot water heaters, in the Longworth House Office Building mechanical room are beyond the end of their expected life. Leaks and other problem are increasing. For this reason, the Architect of the Capitol has decided to replace and upgrade this current equipment to improve the efficiency and safety of the system.

The magnitude of construction for this project is between $1,000,000.00 and $2,000,000.00.
