## Description

40 field calculators: concrete, stone, asphalt, pipe, roofing, framing, crew time and pricing. Works with no signal. No account.

Field calculators that get the order right.

HardHat Calc is 40 construction calculators built by people who order the material. Dimensions in, tons and yards and truck loads out. It works with no signal, needs no account, and every calculator shows the factors it used so you can change them to match your spec or your supplier.

MATERIALS
Concrete slabs, footings and piers, rebar grids, curb and gutter, asphalt tonnage, milling, striping, aggregate and stone, pipe trench with bedding and backfill, directional drilling, cut and fill, demolition debris and disposal cost, water test volume, topsoil and seeding, mulch, sod, pavers and base, retaining wall block, framing, drywall, roofing shingles, siding, insulation, paint, flooring and tile, decks, fences, concrete block walls, and salt for snow and ice.

PRODUCTION AND TIME
Crew hours and days from your production rate, how many people it takes to finish by a date, truck cycle time and how many trucks keep the loader busy, and excavator production.

MONEY
Markup versus margin, a unit price builder with overhead and profit, and what to charge per hour.

FIELD REFERENCE
Slope, grade and pitch, yards to tons by material, a unit converter, and the 3-4-5 square check.

HOW IT WORKS
- Pick your trade and your calculators come first.
- Save a job with its numbers and reopen it later.
- Share a clean text summary to a text message, email or notes.
- Everything stays on your phone. No login, no ads, no tracking.

Made by HardHatOps, from Rochester, New York. Planning numbers only: confirm quantities with your supplier, spec and site conditions before you order.
