Is it OK to sleep over at the terminal?
As
djp98374 said, the construction is not over and the concourse connector is still closed. However, you can exit the B/C secure area and go through security again to enter the D concourse. The airport is open 24/7, and you are allowed to spend the night there if you have a boarding pass for a flight departing within 24 hours.
