Last week we had a shutdown here in Milford. Majority of GM employees have the week off allowing the PDPM team here to get as much work done as possible. Because the parking lots and test tracks are basically empty a lot of asphalt and concrete is replaced. This is one of the few times a year we will have uninterrupted access.
We hire subcontractors to come in and mill the existing asphalt with a huge milling machine.
