August 2008 – The new Frieze Harley-Davidson dealership in O’Fallon, Illinois is the first LEED-certified project in Southern Illinois and one of only two LEED certified Harley-Davidson dealerships in the entire United States. Achieving Gold level certification, the 33,000 sq. ft. facility, houses both the sales and service headquarters for the dealership. With over 40 Solatubes, heating from burned waste oil through a radiant floor system, renewable bamboo wood flooring, low-VOC materials, and electrical needs supplemented by a wind turbine, the facility is expected to be about 40% more efficient than a conventionally constructed building.
TWM provided civil site engineering and surveying services as part of the design team for this unique project. The firm also provided the necessary narratives and calculations in order to obtain the LEED Credit SS 6.2 – Stormwater Management Treatment. In doing so, TWM’s design used two dry detention ponds, a grass swale as opposed to storm sewers to convey storm water to the detention ponds, and porous pavement. These three best management practices (BMPs) reduce water pollution factors created by the development of the site and contributed to the LEED Gold certification.
