Project Description

The East Front of the U.S. Capitol was extended in the early 1960s and contains offices, hearing rooms, and conference spaces for the House and Senate leadership. The building is of monumental construction with very ornate and finely detailed interiors.

 

 

 

 

 

 

exterior of the Capitol to maintain each system in operation as the work of the project progresses. The existing duct distribution system is retained and existing dual duct constant volume boxes are converted to variable volume.

Controls are upgraded and special access panels are designed to blend with the ornate and monumental interior fabric of the building. The access panels provide service access to the variable volume boxes.

The project provides additional capacity, reduced energy consumption and better control for these special areas of this historic building.

The project began with a study phase to identify options, costs, and construction sequences to maintain HVAC support to these critical spaces when Congress is in session.

The design provides for the phased replacement and construction of custom field-erected variable air volume air-handling units located within the existing space constrained mechanical equipment rooms of the building. The design provides for a custom fabricated
temporary air-handling unit mounted on the
