This is Part 1 of our custom home building process guide. This guide was originally written by Susan Bady for newhomesource.com.
- Prepare site and pour foundation: Often, site preparation and foundation work are performed by the same crew, but this may not be the case with a wooded lot. Using a backhoe and a bulldozer, the crew clears the site of rocks, debris and trees for the house and, if applicable, the septic system. The crew levels the site, puts up wooden forms to serve as a template for the foundation and digs the holes and trenches. Footings (structures where the house interfaces with the earth that supports it) are installed. If your home is going to have a well, it will be dug at this point.
If the home has a full basement, the hole is dug, the footings are formed and poured, and the foundation walls are formed and 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. plumbing drains and electrical chases); and the slab is poured.
Once concrete is poured into the holes and trenches, it will need time to cure. During this period, there will be no activity on the construction site.
After the concrete is cured, the crew applies a 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.
INSPECTION #1: When the curing process is complete, a city inspector visits the site to make sure foundation components are up to code and installed properly. This inspection may be repeated depending on the type of foundation (slab, crawl space or basement). Your builder will then remove the forms and begin coordinating step 2, the framing phase.
