Read the takeoff and save the project or export a PDF What can I do with it? - Lay out a rebar grid on any rectangular slab and get bar count, total linear length, weight, and number of standard-length sticks required (including lap overlap) - Configure bar size, on-center spacing, edge clearance, and lap multiplier per local code - Estimate sheets of welded wire fabric (WWF) or rolls with adjustable overlap - Compute concrete volume for slabs, strip and pad footings, square columns, and cylindrical tubes - Count 40, 50, 60, and 80 lb (or 25 kg) bags of concrete mix for fast-setting pours - Add a waste factor and round up automatically - Save unlimited projects with custom names - Export takeoff sheets as PDF for the jobsite or the supplier - Switch between imperial (#3-#8 bar, ft/in, cubic yards, lb) and metric (8-32mm bar, m/mm, cubic meters, kg) What standards does it cover? Rebar sizes follow ASTM A615 (US) and BS 4449 / EN 10080 (metric). Concrete volumes use standard geometric formulas with an adjustable waste factor. Estimates are for planning — always confirm with your structural engineer or local building official. What languages does it support? English, German, French, Spanish, and Japanese.
