To prepare the site for construction, the ESI Team first cleared the 1.3 acre lot by scraping and hauling away all weeds and other vegetation — a process known as grubbing. We then completed several weeks of grading, moving dirt to flatten the building envelope, driveway, and yard areas. Given the front to back slope of this large lot, more than 5,000 yards of soil were trucked to the site and compacted in a specific manner pursuant to building code requirements and as overseen by a 3rd party geological consultant. Additionally, the team then cut in and used wood “forms” to create several concrete retaining walls to hold some of the downslope edge at the back and side of the future home.
Next, the home’s foundation forms were set in place and a network of steel rebar was integrated into the foundation walls and future slab to give the concrete foundation both strength and resistance to cracking and any movement. Meanwhile, the plumbers and electricians completed their first tasks on the site — installing plumbing pipes and electrical conduits from the street to the home and in trenches beneath the foundation walls and slabs. This “stub out” stage makes sure appropriate utilities are available throughout all areas of the home. With the conduits and plumbing in place and covered with sand, soil, and gravel — our concrete trade partner poured the foundation walls, first floor slab, and retaining walls. During this process, team members installed the critical anchor bolts and other such “hold downs” in the wet concrete for the walls to be appropriately anchored in place, as specified by the structural engineer.
Once the concrete was cured, framing material and lumber was delivered and the framing subcontractors started to work their magic in the rough framing stage. Check out the next blog and description of this very active construction phase.
