How tradies use these tools
Construction cost calculator
Builders and estimators use it to sanity-check a quote before it goes out. Pick residential or commercial, the city, the finish level and the floor area. The tool returns an indicative cost per square metre with waste, contingency, overhead and margin shown as separate lines, so you can see where a competitor's number might be thin.
Building materials calculator
Chippies, brickies and site supervisors use it to write a material order from a set of dimensions. Concrete volume for slabs, footings and columns, bricks and blocks per wall, studs and plates for a frame, plasterboard sheets, tiles and paint, each with a standard waste allowance added.
SWMS generator
Trade contractors use it the night before a job that involves high risk construction work. Choose the trade, edit the hazards and controls to match the site, and download a Safe Work Method Statement draft as a PDF. Nothing you type leaves your browser.
