@IcePeasant There are two main contractors that Target contacts with, and a handful of trades that are the same that travel across the country doing Target's so hopefully they mean fixture contractors, everything else really is subcontracted out and even those may have daily subcontactors, especially for things like drywall. It's your responsibility to make sure the painters and drywall people tape off product if it's not being demerched first. Product with paint drops on it will not sell. It's important to think through the maintenance that may have been missed for instance dust on light fixtures if the contractors are removing them may ruin softlines items.
To make things run smoothly you'll need to know the POG plan and the contractor plan every night and have contingency plans. Coming clean in remodel is relative as if your team is trained or mostly trained you'll have enough hours, but the stores I did remodels in have both been 90% brand new and staffing was an issue as we'd get someone in for a week or two basically on the job training only to have them leave and start the process again without any real training hours or they would end up training in a department that had nothing to do with POG.
You're essentially doing a transitional set every day with added construction. The important thing is knowing coming clean every day is relative, but you'll be expected to maintain brand so having a staging area that's at least 10X10 that won't be moved by truck unload and isn't out in a trailer is invaluable. Having dedicated steel space for fixtures really helps too. Coming clean by the weekend is really the main goal, as you're off for two days with store having to deal with how things are left. Use the remodel signs, and figure out what items you want/need to be represented on the floor vs what you can stage.
