Take-OffIntermediate6 min read

Get procurement-ready material lists

The Take-Off agent extracts every material from your drawings with specifications, grades, waste factors, and drawing references. The output is ready to send straight to suppliers for quoting.

What you'll produce

  • Full Room Schedule with dimensions
  • Door Schedule + Window Schedule with totals
  • Trade-by-trade material take-off (one continuous table)
  • 300+ line items for residential, 600+ for commercial
  • Every item with: product code, full spec, quantity with workings, unit, waste %, net quantity, drawing reference, and PROVISIONAL flag
  • Material Summary by Trade — procurement planning view
  • Critical Items & Gaps register

Step 1 — Open the Take-Off agent

Click T — Take-Off in the workspace. Attach every drawing — the more Arc sees, the more accurate the take-off.

Step 2 — Choose your depth

Full MTO

Click Full MTO for the complete take-off across all 18 trade sections.

Trade-specific takeoffs

If you only need one trade, use the targeted templates:

  • Concrete & Steel — volumes, grades, reinforcement, member sizes
  • Timber Framing — studs, plates, lintels, joists in LM by size
  • Windows & Doors Schedule — every W-mark and D-mark with specs
  • Roof & External Envelope — sheets, battens, flashings, cladding, gutters
  • Insulation Schedule — R-values, areas, compliance notes
  • Linings, Finishes & Fixtures — per room with waste factors
  • Procurement-Ready CSV — one flat table ready for Excel/ERP import

Step 3 — Waste factors

Arc applies industry-standard waste factors automatically:

MaterialStandard Waste
Timber10%
Concrete5%
Structural Steel3%
Tiles10–15%
Plasterboard10%
Roofing10%
Paint10%
Reinforcing Steel5%

If you have an experienced crew and want tighter numbers, ask Arc:

"Apply tight waste factors — timber 5%, tiles 7%, plasterboard 5%."

Step 4 — Export to procurement

Click XLSX to download. The spreadsheet will include:

  • A consolidated "Full Report" sheet
  • One sheet per trade for filtering/sorting
  • SUM formulas on every numeric column
  • PROVISIONAL items highlighted yellow
  • Numeric columns formatted with thousands separators
  • Auto-filters on every table

Send the XLSX directly to 3–5 suppliers for quoting. Each supplier gets the same scope — apples-to-apples comparison.

Pro tips

  1. Check PROVISIONAL items first. These are quantities Arc estimated without complete information. If more than 10% of your take-off is PROVISIONAL, get the missing info before going to market.

  2. Use the Concrete & Steel takeoff standalone when your structural engineer delivers drawings — it'll confirm Arc's provisional allowances against engineered quantities.

  3. The Windows & Doors Schedule is perfect for window companies. It's already in the format Schueco, AWS, and local aluminium suppliers expect.

  4. Pair with Estimator. The Take-Off gives you quantities; the Estimator adds rates and margins. You can run both on the same drawings.

Common mistakes

  • Not specifying grades. If your drawings show "timber framing" without stating MGP10 or F7, Arc will default to MGP10. Check this matches your engineer's spec.
  • Missing the finish schedule. Without product codes (MRS01, CLA01), Arc falls back to generic descriptions — less useful for procurement.
  • Using the MTO as a final BOQ. It's excellent as a starting point, but an experienced quantity surveyor should verify before you commit to tender quantities.
