Coordinating shutdowns on a tight bridge timeline

We’re rebuilding the Maple Street bridge on a 16-week schedule, but utility cutovers keep drifting and chewing up our float. The 24-inch water main needs a 36-hour shutdown in week 6 while gas and fiber are night-only. My P6 update shows we’ve burned 12 days of float — how are you locking utility owners to firm dates without blowing the critical path?
