Quick, practical calculators for the numbers you work out on site every week — construction cost, concrete mix, steel, brick count and BOQ rate analysis. Built by the same team that builds CrewSense's own estimator and BOQ module.

Why we built these
CrewSense already runs the cost estimator, BOQ and material tracking for contractors managing live sites. These calculators are the same math, pulled out and made free to use — no account, no project, no data saved anywhere.
They're indicative estimates for planning and quick checks, not a substitute for a structural engineer's design or a detailed rate analysis on a signed contract. Every calculator says so before you get a number.
If you're already tracking these numbers project after project, that's what CrewSense's BOQ, estimation and material modules are for — the same calculation, but saved against a real project, updated as the site changes, and shared with your team.
Run these numbers project after project?
CrewSense saves every estimate against the actual project, tracks it as work happens, and gives your whole team the same live numbers.
