On the commercial side:
I run a temporary loop to a meter and panel on a pole, then build the service on the outside of the building after the brick go on. The temporary service is part of an allowance on all my bids, the GCs are free to exclude it from the contract should they choose but if they do then they take care of temp power, not me.
Our local criteria and AJH will not allow the permanent service to be energized as a temporary until certain things have been done; one of which includes an inspection that a service jerry rigged to be hung pre-brick would not be able to pass. Some of the other things they insist on before turning on the permanent power are working toilets in the building (I still have not figured this one out yet), and the job must be 100% dried in.
There have been a few occasions when the sheet rocker or mason has held up my work, and out of defense my scope had to proceed. When this happens I build up a strut rack that suits my needs and meets code and start mounting equipment. This generally makes the sheet rocker or mason curse my name as they work around a struck rack that they cant rip out.
