General Motors has tapped CBRE Group to sell its former manufacturing plant in Janesville, Wisconsin. Originally built in 1919 on a 250 acre site, it was the oldest operating General Motors plant until being shut down in 2009. The fully equipped rail-served manufacturing facility consists of the 3.8 million square foot main plant and six other buildings. Most of the buildings on the property were constructed after 1970. “We have a deep understanding of the magnitude of this property and its importance to the Janesville community,” said Tom Simon, who is a founding member of the CBRE Special Properties Group that specializes in major industrial facilities outside of metropolitan areas. “Accordingly, General Motors and CBRE are committed to finding a buyer as quickly as possible.” A price for the facility has yet to be determined.
