Project Calc: Construction Math for the Jobsite

Field notes

The homepage organizes seven calculators around common construction estimating tasks, from fence takeoffs to concrete, gravel, volume, and unit conversion. Fence material calculations explicitly cover posts, rails, pickets, and waste, while post-hole concrete accounts for post displacement and bag quantities. The site says results preserve precise math while rounding purchase quantities upward, and it provides a methodology link for formulas, assumptions, and worked examples.
