Quantity takeoff software that produces the numbers a bid is built on: how many, how long, how much area, how much volume. Measured on PDF drawings with AI assistance, checked by an estimator, reported in the units your suppliers and subcontractors quote in.
Quantity takeoff is the measurement of what a project physically requires, expressed in the units it is bought and installed in. Concrete in cubic yards. Formwork in square feet of contact area. Rebar in tons. Drywall in sheets or square feet. Conduit in linear feet by size. Doors in each. The list is the skeleton of the estimate — every cost line hangs off a quantity, and a quantity in the wrong unit is worse than a missing one, because it prices out to a plausible number nobody questions.
That is why quantity takeoff software is not just a measuring tool. It has to know that a wall area needs its openings deducted but its corners counted once, that pipe is bought in lengths and priced per foot, that a 10% waste factor on flooring is normal and a 10% waste factor on structural steel is not. BidcoreAI carries units, deductions and factors per scope item, and shows the factor as applied rather than baking it into the number.
The measuring itself runs on the PDF plan set in the browser. AI proposes quantities for repeating conditions across every sheet; an estimator reviews them against the drawings and the specifications. Quantities can be grouped by scope, by level, by phase or by bid package, so the same takeoff produces a supplier material list, a subcontractor package and an estimate structure without being measured three times.
Everything stays traceable. Each quantity records the sheet, the scale and the person who confirmed it, and exports to Excel with those references intact. Whether the number ends up in a bid form, a purchase order or a schedule of values, someone can follow it back to a line on a drawing — which is the whole point of doing a takeoff instead of estimating by square-foot rule of thumb.
Measured once, reported in whichever unit the supplier, the subcontractor and the estimate each need.
Anything discrete and repeating, counted across the whole set rather than one sheet at a time.
Runs traced on the drawing, split by size, type or level so they can be bought and priced correctly.
Areas with deductions handled explicitly, because gross and net are different numbers with different uses.
Depth taken from the sections and details, never inferred from plan area alone.
Weights calculated off schedules and section properties rather than assumed as a ratio of another quantity.
Measured quantities converted into what actually gets ordered — sheets, rolls, bags, sticks and pallets.
A takeoff tool measures. A quantity takeoff tool has to produce numbers you can buy from.
Repeating conditions found and measured across the set, presented as proposals with the drawing evidence attached.
Each scope item carries its own unit and conversion, so a linear measurement can report as LF, as sticks, or as both.
Factors set per item and displayed as applied, so nobody double-counts a 10% allowance that was already in the number.
Openings, penetrations and excluded zones deducted by rule, with gross and net both retained for different downstream uses.
Counted quantities checked against door, window, fixture and finish schedules, with mismatches flagged as RFI candidates.
The same quantities reported by trade, level, phase, room or bid package without re-measuring anything.
One measurement yielding several quantities — measure a partition and get studs, track, board, tape, screws and insulation.
Purchase-ready summaries rounded to order units, suitable for sending straight to a supplier for pricing.
Sheet, scale, coordinates and author recorded on every quantity, and carried into the Excel export.
Quantity sheets in the format bid forms and purchasing systems expect, with references intact.
Confirmed quantities priced in the same workspace against your own unit costs, with no export in between.
A second estimator can review and sign off quantities before they are priced, with the changes recorded.
The measurement types change by trade. The workspace does not.
Quantity takeoff is the same discipline whether the job is a fit-out or a treatment plant.
The sequence that keeps units, factors and references intact all the way to the export.
The quantity is the part of an estimate that survives contact with the field.
A quantity in the wrong unit prices out to a believable number that is quietly wrong. Carrying units per scope item is the cheapest protection against that class of error.
The same takeoff produces the estimate structure, the subcontractor packages and the supplier material list — three deliverables from one measurement.
Factors shown as applied rather than baked in stop the double-counting that happens when one estimator adds waste to a quantity another already grossed up.
Sheet references on every line mean a quantity queried after award can be shown rather than argued about — and re-checked in minutes.
Material summaries rounded to order units let procurement price the job while the estimate is still being assembled.
Consistent units and factors across jobs make your historical quantities comparable, which is what turns a cost database into something worth pricing from.
Built by people who have had to defend a quantity to a client six months after award.
Every scope item carries its unit, conversion and rounding rule. Quantities come out ready to buy from, not ready to convert.
Waste, laps and conversions are shown as applied, so two estimators never gross up the same number twice.
Counts are reconciled against the drawing schedules automatically, which is how most miscounts get caught before bid day.
Every proposed quantity comes with the sheet and location it was taken from. You are reviewing measurements, not accepting outputs.
Excel quantity sheets and marked-up PDFs — what a supplier, a client and an accounting system each need.
Concrete volumes, steel tonnage, duct weight and finish areas measured in the same project on the same set.
If what you need this week is finished quantities rather than a tool to produce them, the service side handles it. Estimators working in this same platform measure the set, reconcile it against the schedules and return a quantity sheet with the marked-up drawings and assumptions behind it.
One platform, one cost database, one set of drawings — whichever scope you are pricing today.
Bring a set with quantities you already know. Comparing them line for line is the only test that settles anything.
