Ask SiteworkMath
Ask about how the calculators work or how to read the numbers — material takeoff, yardage, bag count, waste cushion, the practical-order math. Free, no signup. Joist, beam, footing, ledger, permit, code-compliance, and any structural questions go to a structural engineer, licensed contractor, or your local building department — not this assistant.
Hi, I'm the SiteworkMath assistant. I answer questions about the calculators and guides on this site — concrete yardage, topsoil, mulch, tile, and decking material math. I'm not a structural engineer or a licensed contractor; I'm a calculator built around the math that James Wu — Chicago-area flipper — uses on his own jobs. For structural decisions (joist sizing, beam spans, footing depth in your soil + climate, anything that needs a permit) talk to a licensed structural engineer or your local building department.
SiteworkMath is not a structural engineer or licensed contractor. The assistant covers calculator math, material takeoff, and sitework basics — not structural design, code compliance, or personalized project advice.
