Rough carpentry, electrical and HVAC

Ben asks:

I am having a contractor open a walkway in a load bearing wall this week. However, he is only finishing the rough carpentry, and will not be moving the electrical outlet that ties to the upstairs as well, or the central vac connection. I am wondering if the moving of these mechanicals is harder after the contractor has completed his rough work, or if it will be of equal difficulty after rough work as it would have been before. And about the central vac connection, can that be flush mounted in the floor? The flooring will be 3/4" hardwood. Thanks!

Ben,

Usually the rough carpentry is completed prior to the mechanical (plumber, HVAC and electrician) trades appearing on the job.  If some of the wires etc. have to be cut,  make certain to note how they were installed originally.  It’s not a bad idea to take some photos of the wall after it is opened up and before anything is moved out of the way – your tradesmen will appreciate this.
