What this one covers
- 1
The water: what the roof sends you, what each pipe carries, and why the wall of the pipe matters more than its diameter.
- 2
The real bill of materials, sourced, and the trench: the 6 inch costs $444 more and saves 11 yards of digging.
- 3
The flip: by hand the 6 inch wins, with a machine the two 4-inch lines win.
The sheets
Prices are mine. Yours are different. The math is the same.
Ledge is software for landscape design-build. These sheets are the thinking underneath it.
Every number on these sheets is the kind Ledge carries for you on a real job: the burdened hour, the man-hours a price buys, what the crew actually did against it. The first ten shops run Ledge free; we make money only on payments. If you want to see it on your own jobs, there's one person to talk to.
