General Motors Co. is within a month of starting construction on a $44.5 million logistics center at its Lansing Grand River assembly plant.  The Detroit automaker has started to move dirt in preparation to start building.  The 400,000 square-foot facility will be connected to Lansing Grand River's general assembly building and is expected to create 200 jobs.  General Motors Co. will spend nearly $1.3 billion at five factories--three in Michigan--in a wide-ranging plan that will include production of what could be the auto industry's first 10-speed automatic transmission.
