Some Notes on the Mechanical Systems

The timing? Electrical, plumbing, and HVAC rough-ins should take roughly two to three weeks. The insulation will happen in a day or two. But delays are com­mon at this stage.

If you are living in the house, particularly with young children, you need to be sure that all the tradespeople secure their tools, equipment, and overall work areas daily. Establishing a child- and pet-free zone is a must, but it's also a good idea for you to make it a habit after the workers leave each day to make an inspection—try to anticipate any hazards to you or your children, inside the zone and out. This means the work site should be clean and organized. If you have any safety problems or con­cerns, discuss them immediately with the general contractor or the subs involved.

The local building inspector will probably have visited during the foundation work, but he's guaranteed to come now. In fact, different inspectors may arrive to look at plumbing, electrical, and other work. Unless you're acting as your own general con­tractor, this probably won't be your responsibility. Your subs each should arrange for the inspectors to visit—and make sure their work passes the inspections.
