National Park Service -George Rogers Clark Memorial

Constructed in the 1930s to honor George Rogers Clark, this circular granite building consists of a 40-ft. high rotunda with a glass ceiling. The interior features seven historically significant murals, along with three of Clark’s quotations. To address a failing mechanical system, 360 Engineering provided new mechanical and electrical systems. The granite walls posed a unique challenge, as they did not allow new chases to be created for routing conduits, pipe, or ductwork. Several options were explored including replacement of the existing steam boilers and reuse of the existing steam lines, installation of new high-efficiency heating water boilers and reuse of the existing steam lines as hydronic lines, converting the building to electrical power, or a new geothermal system. With the design team’s input on the pros and cons of each option, the client decided on a new geothermal system, which entailed creation of 18 300-ft. deep boreholes, which were installed in an archaeologically clear area south of the memorial.
