The construction elevators can come down before or after the crane. It's easier/faster (and arguably safer?) to take the elevators down by using the crane but the mast sections are usually about 4 feet tall and can be unbolted and stowed on the roof the cabs for the ride down to the street along with the tie-ins to the building. So often the construction elevators (hoists) need to remain longer than desired due to the permanent elevators not being signed off for construction use (let along permanent use).
