Field & Material Calculator
Run the takeoff at the desk. Prove it in the trench.
The quantities, takeoffs, and material orders an underground crew runs on — office and field, one set of numbers. 79 calculators for trench, pipe, grout, aggregates, trucking and asphalt, from bedding to grade.
Ten categories covering the whole scope — trench, pipe, aggregates, concrete, asphalt, earthwork. Every quantity a takeoff needs, in one place.
No signal in the hole, no problem. Everything runs on the device — nothing to load, nothing to wait for.
A tape doesn't speak decimals. Punch in feet, inches and eighths, then insert the result into any field in any calculator.
Bedding classes, trench sections and pipe zones drawn to what you selected — with the bedding factor shown, not buried.
Every quantity saved under its project, with the inputs behind it, and out to a clean PDF — so the order is right and you can show why.
The same numbers the crew runs in the trench, the PM checks at the desk, and the estimator builds the bid on — one source of truth, start to finish.
Save a calculation and it becomes a clean field report — job name, project, every input, every result, your notes. Order off it, drop it in the project folder, or hand it to the office. The three-zone trench here names the material and density for every zone — #57 stone, loose clay, crushed stone — so the quantity behind each ton, and what to order, is right there on the record.
Because below grade is its own trade.
Every calculation is built using recognized engineering references, published standards, and accepted industry practices.
Every result keeps its inputs, assumptions, references, and intended application — a transparent record that supports confident project decisions.
Recognized standards. Transparent calculations. Defensible results.
TrenchLine Calcs is in closed beta ahead of launch. Tell us what's broken, what's missing, and what you'd actually use on Monday morning.
