You would however need to modify your substantial completion acceptance date, or provide for "temporary construction use" much like we do with elevators that are used during construction and then have additional warranty requirments at the time of completion.

The company that you need to be consulting with is called Munters. Helaine K.

It would need to be installed, powered, and available to provide the cooling when the finishes are going in. I suspect this would be unlikely. A system such as Munters mentioned above is probably going to be more usable.

In consultation with the local fire department, we required sprinklers to be functional on occupied floors, and barricading of stairs so any one egressing in an emergency will not try to go up [into unfinished space]for escape. Seems good ideas for the early occupancy issue!

But Ralph raises some other very important questions regarding partially occupied buildings. It is worth noting that there have been some significant high-rise fires relating to areas under renovation that affect occupied floors.
