I had 2 people helping me. The plano team replaced any carry forward signing according to their plano. They handed off the planogram, to someone I had auditing behind them, putting up any missing new signing or previous weeks carry forward signing. I had someone with me at all times, that I could gopher around.
My helper and I would organize the old signing that came down that may be used at a later date, audit left over signing every day to determine if it could be tossed, set out new signing according to what was being done for the week, put up graphics, keeping track of what the construction was doing to be sure they were putting he right fixtures in the right areas, keeping the trailers organized, and ordering anything missing after reading the backorder lists. I kept red tubs with daily signing clean and organized. A tub for endcap signing components, one for category signs, one for misc hardware. These will stay up for the entire time you are remodeling.
Do you have a strong signing person? Can they handle being under pressure? If not, I would recommend asking for help from a strong signing tm from another store. They could come once or twice a week to make sure everything is running smoothly.
