A few weeks ago it was reported that Transformers 4 production team was scouting the GM Weld Tool Center in Grand Blanc, Michigan. Now Michigan Live is reporting the team has decided to pass due to scheduling conflicts. The plant is closing in July but apparently production needed to to use the site before then. Of note is a comment about there was also some discussion about leaving some equipment behind for part of the film." It seems that while TF4 needed the space minus employees getting in the way, it also wanted the industrial equipment for whatever the set would have become. Bay loves his big machines so be interesting to see what site they chose instead. Thanks to Wynton R. for the link.
