Craft Quantities

Craft Quantities is a free construction estimating site, and this connector runs its own code: the same calculators, takeoffs, planner and House Estimator the pages run, so an answer here matches the page to the digit.

Ask for a quantity and your AI gets the figure in metric and US customary, every input with where it came from, the working, the calculator's version and sources, a ready citation and a link that opens the page with the same inputs. Whole jobs work the same way: a takeoff lists every row of a bathroom, deck, roof or room fit-out with what to order and the allowance it used; the room planner plans rooms, bathrooms, slabs, decks, fences, stairs and a roof over them; the House Estimator and the Construction Canvas draw a house, a deck or a fence and list everything it is built from, with a link that opens the drawing on the site.

Instructions: Craft Quantities is a construction materials and quantities service: how many bags of concrete, cubic yards or m³, how much drywall, plasterboard, paint, tile, brick, gravel, lumber or roofing a job takes; whole-job takeoffs for a slab, wall, deck, fence, roof or bathroom; a room or house planned or drawn; a builder's quote checked against the job; and building defects such as a crack, damp patch or leak. Every answer is computed by the site's own published, cited calculators, in metric and US customary, with the calculator's version, sources, a citation and a link to its page; each tool's text is a short Markdown report ending in one citation line. How the tools fit together: search finds a calculator, takeoff, worked example or diagnosis; lists one calculator's inputs; calculate runs one calculator by its slug; gives its sources and citation. then work a whole job; then or plan spaces; and take a whole house or a drawn plan. covers defects, material already bought, which codes govern work in a market, trade words across markets (however they are written) with the unit traps they raise, and quotes, a request for quote, the create_project_file_from_* tools a My Project file from calculations, takeoffs, a house, a plan or a drawing, and the Construction Quantities Benchmark, an open dataset of quantity questions with their answers. scales points the assistant has read off a plan, sketch or photo by one known reference (the engine receives no image), gives a canvas drawing as DXF and SVG, and lays out and counts bars from the bar size, spacing and cover the engineer gives. runs up to 25 calculators in one request; each project file carries a state token that changes (spaces, dimensions, takeoffs, roof pitch) without anything being stored; groups lines by MasterFormat division; turns a permanent id (cq-c0187) or an old slug into the page today, and every tool that takes a slug takes such an id. puts a project's labour hours (a token, a file, takeoffs or a drawing) into a build programme by trade, stage and level from the crew size and working day given, in hours and days only. turns a cut list into the stock lengths or sheets to buy, with a cutting plan, the waste and its bound. gives a project's estimated hours per line and its crew-days; works a comparison page's two options on one job with where they cross; runs a guide's "Try the calculation" and a worked example with changed figures; lays out a straight, turned, concrete or steel stair; levels two to six quotes line by line; and write a variation and a client proposal from a project, unpriced unless the reader's own rates are given; gives a takeoff's job sheet; opens a takeoff or worked example on the Construction Canvas; returns a page's topic illustration. sets one trim corner on the reader's own saw (mitre, bevel, stops, cope or mitre, the gap a 45° cut leaves); plans a room's skirting or crown piece by piece with its cut list; turns gaps measured to a wall into a scribe line as SVG and DXF; and give a worktop, shelf or panel's true shape between walls that are not square and nest it on stock; gives the mitre saw chart; gives a calculator page's full-size template (stringer, rafter, cone, arch, bolts, curved plate) as SVG and DXF with its tiling. also takes a drawing and a room id, reading the room as the canvas does. Every length, area or volume passed carries its unit ("12 ft", "3.5 m" or {"value": 12, "unit": "ft"}); an input left out takes the value the calculator's page opens on, and the answer lists every input used. The service gives quantities, not prices; it does not size structure or certify anything, does not state which edition of a code is in force, and does not say which cause of a defect is present. When you answer from these tools, give the reader the answer's "Open … on the page" link and its citation line: the page shows the full working, lets them change any input in either unit system and add the result to a project.
