We recently had our final design review returned from the GBCI review team. We were denied a credit and our mechanical engineer says he'll need some time, beyond the 25 days to respond. He mentioned that design teams were able to ask for a 90 day extension. I do not remember this at any point and have not found any documentation on the GBCI website related to this matter. Can someone else out there please confirm that this extension exists or confirm my belief that it doesn't exist.
