We’ve previously looked at how construction costs compare across different locations, and different building types. But an overall cost number only tells you so much. It’s useful to dive a little further and see how that money gets spent. How much is going to the framer? How much is for the foundations? How much is for plumbing? Let’s take a look.
Hi! New to your site ... An observation about onsite labor as a % of total construction costs. In calculating it as near-50% for both the construction cost estimator and the Bohannon budget, aren't you leaving out the cost of all the subcontracted-out work and the overhead budget? If you include them, "labor" is 25%. This makes sense and is similar to what BLS studies of apartment and SFH construction found in the early 1970s and what the Economic census of construction finds in its massive study every 5 years: construction worker pay + an estimated share of fringe benefits is approximately one-quarter of total net construction receipts. See page 8 of this NAHB breakdown of the Economic Census data ... https://www.nahb.org/-/media/NAHB/news-and-economics/docs/housing-economics-plus/special-studies/2021/special-study-home-building-census-july-2021.pdf
With electrical, you have a much larger quantity of electrical/data systems being installed. The combination of power hand tools and easier (in some cases) installation, is negated by the greater amount of materials to install.
Appreciate it... Very concise showing estimates from past and those current...
