HVAC Replacement Historic MS River Commission

HHB Engineers has been selected, along with TAG Architects, for the HVAC Replacement of the historic 1894 Mississippi River Commission Building in Vicksburg, MS.  The General Services Administration (GSA) is managing the project.  The building is 59,000 square foot four-story National Register (NR Rating – 3) listed Gothic / Romanesque Revival-style Post Office and Customs House that fronts Walnut Street in Vicksburg, Mississippi, and is now known as the Mississippi River Commission building. This is one of the more prominent buildings in Downtown Vicksburg. Of special interest is an eight-sided tower that surmounts the roof at the northeast corner and is topped with a conical roof. Construction of the building began in 1890 and was completed in 1894. William Freret designed the original building. The building was extended on the south side in 1914. Three of the building’s stories are above-grade, and there is a partially exposed basement level. The property is occupied by the U.S. Army Corps of Engineers (COE).

The project will replace the entire HVAC system of the building, while some of the building is to remain occupied.  The design should include sustainable and energy efficiency strategies where feasible.  Challenges include limited space for ductwork and equipment.  Electrical and Architectural elements to be upgraded as required for the HVAC work.

Initial project budget is $2.8M.
