What It Does
The HeavyCalc helps you:
Cut Costs & Errors
Boost Estimate Accuracy
Produce Job-Winning Bids
Improve Crew Productivity
At the estimating table, in the truck or on every crew member's tool belt, the HeavyCalc helps get every job done right the first time! Quickly master the following construction problems, in the office or out in the field:
Area & Volume Calculations
Prevent errors & save keystrokes with automatic calculation of area and volumes. Length, Width, Depth, Area & Volume keys allow for fast & accurate material estimates.
Lets you convert between weights (lbs, tons, kg) and find weights of any material (e.g., tons per cubic yard). Figure truckloads and weights and improve your bottom line.
Existing, Proposed & Cut/Fill Keys
Simplifies soil-volume cut and fill estimates.
Shrink & Swell
Solve Bank, Compacted and Loose soil volumes for any job.
Percent Grade and Slope
Instant right-angle solutions for finding diagonals, square-ups, and staking-out drops, grades, ramps, drainages, trenches, and more! No more formulas or memorization of Pythagorean theorem!
Speeds grid-cell cut/fill estimates.
Dimensional Math & Conversions
Works in all dimensional formats: quickly add, subtract, multiply, divide and convert in feet-inches-fractions, decimal feet, decimal inches, inches and fractions, yards, meters, millimeters, board feet, as well as square and cubic formats.
Handles all fractions-1/2's, 1/4's, 1/8's, 1/16's, 1/32's, 1/64's
Work in fractions for all sorts of dimension problems. You can even set fraction denominators to display your desired accuracy (in above fraction formats).
"Smart" Fraction Setting
Saves keystrokes by entering preset fraction denominators for you, from 1/2 to 1/64.
Lets you review the last 20 entries, for double-checking answers.
Works as a regular math calculator, for your everyday math needs.
