Cornerstone Earth Group, Inc. performed Geotechnical Investigation for Underwood & Rosenblum, Inc. and Sonic Automotive for the Autobahn Dealership in Belmont, California. Our field exploration consisted of both conventional borings and Cone Penetration Tests that required coordinating efforts with the San Mateo County Environmental Health Division.
The project required demolition of the existing dealership and constructing a new, approximately 57,000-square-foot, dealership building. The main spaces in the building will be a one-story automobile showroom and service areas. In addition, there will be a two-story lounge. The site also includes a 1300-square-foot carwash and construction of a new retaining wall along the southern side of the site.
