Test our live estimators directly. Calculate exact volumetric specs and material counts without page reloads.
Comprehensive, field-tested estimation tools organized by trade discipline.
Tonnage, thickness, weight, HMA, bitumen, and paving conversions.
Excavation, backfill, topsoil, gravel, sand, mulch, and plant spacing.
Slabs, footings, CMU, rebar, mortar, steel, framing, and retaining walls.
Paint, tile, drywall, lumber, truss height, and post-construction cleaning.
Pool cost, cistern volume, tank capacity, solar, civil, and project cost estimators.
Unlike generic tools that use rough estimation, MultiTooSite builds every calculator around strict civil engineering standards published by ACI, NAPA, and ASTM International.
Incorporates standard 5% to 15% field loss contingency for spillage and uneven subgrades.
Uses exact steel density formulas (W = D²/162 kg/m) for rebar sizing and lap splices.
Calculates hot mix asphalt based on 145 lbs/cu ft compacted density per ASTM D3515.
Calculates ASTM C270 mortar bag coverage per 100 CMU blocks or 1,000 bricks.
