Without the window (but knowing the RO) they should be able to fully sheath the exterior. Some towns will allow you to do plumbing and electrical, some won't (ours won't). They should be able to do the roofing. But they won't be able to trim or side that exterior wall, but they could do the corner boards and trim and side the other walls. Hopefully someone else will speak up and let me know if I missed anything.

Four weeks is a long time to be held up over a window. If they are already at sheathing they (actually, you) should be ready for interior work long before that window comes in. Personally, I'd pay the extra money to get it there quicker. In the great scheme it's not that much money.

Thanks Sue, I agree completely, the money is not that much at all. Its the point of feeling strong-armed.

Without knowing a lot more; I'd agree with the contractor. New construction windows are totally different than replacement windows, so to properly install them, they need to go in before the rest of the exterior wall assembly. Without the exterior wall assembly completed, there's no drywall or insulation (because of the danger of leaks), which means no point in electrical or plumbing. Some of that is kind of paranoid; but rather than being strong-armed, it sounds quite the opposite; the builder is looking out for his, and YOUR best interests on this project.

I see your point jasonmi7, the only thing is he isnt doing the insulation, drywall electric or plumbing. I guess it just really struck a chord with me as he has been a bit passive aggressive with me all along. Better to get it over with and move on.

Even if he can do most of the siding, know the equipment (jacks, etc.) has to be removed for use elsewhere, and then brought back.

Interruptions like this play havoc with trying to get things done efficiently.

Every time a sub must return to finish part of the job is money out of his pocket, or money the GC must pay him reducing his profit.

Jobs are usually bid based on the amount of work, but the number of trips gets rolled in.

The plumber knows on new construction he will have to do rough in work before the slab goes in, then return for the interior rough in, then return again for finish work.

If a bathroom vanity is missing when the plumber is there for the finish work, he will need to return again.

Time is money, and the more time you spend working and the less traveling the better.

If it's only one window he should be able to work around it.
