PCS, Inc. was contracted by CMF Engineering, Inc. to provide selective demolition services to the Smithsonian Environmental Research Center brick mansion ruins located on the 575-acre historic property of Contee Farm. PCS demolition crews removed tree stumps, roots, rubble and soil around the ruins and salvaged all brick onsite. Crews excavated soil down to the basement levels in two areas of the mansion, all by hand. To avoid affecting the structural integrity, PCS was not able to use any heavy machinery onsite.
