The National Museum of the American Indian is a 322,000 sq. ft., multi level museum of the Smithsonian Institute dedicated to the preservation, study and exhibition of the culture of Native Americans.  The museum was established by an act of Congress in 1989 and is located on the National Mall in Washington, D.C.  The HVAC system for this project includes (70) custom chilled water air-handling units, (3) hot water heating boilers, (3) steam boilers, (43) fans, (29) pumps and several hundred feet of finned tube radiation.  Most of the walls in the exhibit areas and all the exterior walls are curved making coordination and proper placement of the work particularly difficult.  The building column lines radiate from points, rather than the traditional grid layout.  The plumbing systems are comprised of (100) fixtures, (14) pumps, (6) grease and oil interceptors, laboratory vacuum pumps, air compressors, a central drinking fountain system, (9) hot water generators, and a large kitchen and cafeteria.
