Is there a way to build a highrise building, lets say 30 stories + and turn on A/C in bldg as building is erected - in segments, for example in order to avoid the mold and mildew problems that occur when A/C is not in operation until CO is received?

some buildings I've worked on have floor by floor or zoned systems that can be handled that way. 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.

HVAC often have very little imapcact on a buildings humidity issues during construction. The company that you need to be consulting with is called Munters.

Since the cooling needs to be working to provide the necessary moisture removal, a lot depends upon the design of the system, especially the location and installation schedule for the chiller plant. 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.

Had this situation once when I was a code official [another life ago!). 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!

I'm assuming that anon's request was for an as-yet unoccupied building. 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.
