Wiring for telephones, cable TV and music systems is included in this work. HVAC vent pipes are installed through the roof, and insulation is installed in the floors, walls and ceilings.Īfter the roofing is on, the electrician installs receptacles for outlets, lights and switches and runs wires from the breaker panel to each receptacle.
Bathtubs and one-piece shower/tub units are put in place.ĭuctwork is installed for the heating, ventilation and air-conditioning (HVAC) system, and possibly the furnace. Sewer lines and vents, as well as water supply lines for each fixture, are installed. At this time, the electrical and plumbing contractors can also run pipes and wires through the interior walls, ceilings and floors. Once the shell is finished, siding and roofing can begin. Stage 3: Rough plumbing, electrical, & HVAC This reduces the likelihood of mold and wood rot. The sheathing is then covered with a protective barrier known as a house wrap to prevent liquid water from infiltrating the structure, while allowing water vapor to escape. Plywood or oriented strand board sheathing is applied to the exterior walls and roof, and windows and exterior doors are installed. The floor, walls and roof systems are completed. The builder will then remove the forms and begin coordinating stage 2, the framing phase. This inspection may be repeated depending on the type of foundation (slab, crawl space or basement). INSPECTION #1: After the curing process, an inspector visits the site to ensure foundation components are up to code and installed properly. After the concrete is cured, the crew applies waterproofing membrane to the foundation walls installs drains, sewer and water taps and any plumbing that needs to go into the first-floor slab or basement floor and backfills excavated dirt into the hole around the foundation wall.
Once concrete is poured into the holes and trenches, it will need time to cure. plumbing drains and electrical chases) and the slab is poured. If it’s slab-on-grade, the footings are dug, formed and poured the area between them is leveled and fitted with utility runs (e.g. If the home is designed with a full basement, the hole is dug, the footings are formed and poured, and the foundation walls are formed and poured. If your home is going to have a well, it will be dug at this point. Footings (structures where the house interfaces with the earth that supports it) are installed. Stage 1: Site preparation & foundation pourĪfter clearing the site of trees and debris, the construction crew levels the ground, puts up wooden forms to serve as a foundation template and digs any necessary holes and trenches.
