Consultant said the longest path was the Critical Path "The attached longest path goes through the Package 2 permit, followed by the Caisson work for D, then E with the remainder of the building work for Area E through March 28th into Punchlist and Turnover." I ran the Float Path listing - The critical path goes through package 2, then through Area C is shown completing on May 1, 2023 which is the Substantial Completion". I think the path that goes to Substantial Completion is the crit path not to the last item on the schedule Chances are they need to change their logic.
