AI-generated scene with Bid Sharp banner
People use the words material takeoff and quantity takeoff as if they meant the same thing, and on a small job they often do. On a bid with several trades the difference matters, because it decides what you can price from the list and what you still have to figure out. This guide explains both, shows where they overlap and tells you which one to order at each stage of a bid.
What is a material takeoff?
A material takeoff is the measured list of products you have to buy: studs, sheets of drywall, cubic yards of concrete, linear feet of pipe, number of fixtures. Each line has a description, a quantity, a unit and, ideally, the sheet or detail it came from. The material takeoff feeds purchasing and supplier quotes. It answers one question: what do we need to order, and how much?
What is a quantity takeoff?
A quantity takeoff is wider. It measures all the work shown in the drawings and described in the specifications, including items that are not products you buy. Examples are square feet of surface preparation, linear feet of trench excavation, area of formwork, hours of testing or the number of pieces of equipment to set. Labor, equipment and subcontract pricing depend on these measured quantities. It answers a bigger question: how much work is there to build this?
Side-by-side comparison
| Question | Material takeoff | Quantity takeoff |
|---|---|---|
| Main purpose | Buy list for suppliers | Basis for the whole estimate |
| Typical units | Each, sheets, bags, cubic yards, tons | Square feet, linear feet, cubic yards, counts, plus work items |
| Includes labor items? | No | Yes (installation, forming, finishing, testing) |
| Used by | Purchasing, suppliers, fabricators | Estimators, general contractors, subcontractors |
| Output | Material list with waste factors | Quantities by trade or CSI division, marked-up plans |
Where the two overlap
Both start from the same measurements. If you measure 1,200 square feet of slab, that figure produces the concrete volume for the material list and the finishing area for the labor line. A good takeoff is built once and used for both. That is why many estimators keep one organized takeoff, often by CSI MasterFormat division, and pull the material list from it.
An example: a wood-framed partition
A partition is 60 linear feet long and 9 feet high. The material takeoff lists studs at the chosen spacing, top and bottom plates, blocking, sheathing or drywall, insulation and fasteners. The quantity takeoff carries the same wall as 540 square feet of partition (60 x 9), plus the work attached to it: framing labor per linear foot, board hanging and finishing per square foot, and the finish level the specification calls for. The estimator multiplies the second set of quantities by labor rates. The first set goes to the supplier.
Which one should you order?
- You are a supplier, fabricator or buyer: a material takeoff is enough.
- You are a subcontractor pricing your own scope: order a quantity takeoff and apply your own labor rates, or ask for a complete priced estimate.
- You are a general contractor with many trades: a quantity takeoff by CSI division makes it easier to level subcontractor bids and spot gaps.
- You are a homeowner or developer checking a quote: a quantity takeoff shows whether two contractors priced the same amount of work.
Waste, overage and what a takeoff should state
A material list normally carries waste or overage so you do not run short. Cut waste on drywall, tile and framing lumber differs from the spare allowance on concrete or pipe fittings, and the right percentage depends on the project and your crew, so a takeoff should show net quantity, the waste factor applied and the final order quantity as separate figures. Visible assumptions can be reviewed and changed; hidden ones cannot.
Common mistakes
- Pricing from a material list and forgetting the labor-only items (layout, protection, testing, cleanup).
- Mixing units, for example square feet in the plans and linear feet in the supplier quote.
- Measuring from an outdated drawing set after an addendum.
- Leaving out alternates, allowances and unit-price items that the bid form asks for.
Where the information comes from
Quantities come from the drawings, but the scope comes from the specifications. A drawing may show a door; the specification says which hardware set, finish, fire rating and installation requirements apply. A takeoff that reads only the plans produces a clean-looking list that misses requirements, which is why estimators read the relevant specification sections, addenda and bid form alongside the sheets. Division 01 (General Requirements) also adds items that never appear on a plan, such as temporary facilities, submittals, testing and closeout documents.
What a good takeoff looks like
- Organized by CSI MasterFormat division (or the bid-package structure), so each trade can be priced or leveled on its own.
- Traceable: every quantity points to a marked-up sheet, so a second person can check it.
- Consistent units: one unit per item, converted to the purchasing unit only at the end.
- Clear assumptions: waste factors, rounding, deductions for openings and anything that was missing from the documents.
- Delivered in a usable format: Excel for pricing, PDF with marked-up plans for review.
A quick decision checklist
- Do you need to price labor or equipment? If yes, you need a quantity takeoff.
- Are you only ordering products with a supplier? A material takeoff is enough.
- Is the bid due soon and the set large? Ask for the trades that carry the most cost first, then the rest.
- Will subcontractors price part of the work? Organize the takeoff by division so each scope sheet matches the quantities.
- Did an addendum arrive after the takeoff started? Send it right away so affected quantities are re-measured.

Frequently asked questions
Is a material takeoff the same as a quantity takeoff?
+
Not exactly. A material takeoff lists the products to buy. A quantity takeoff measures all the work, including labor and equipment items, so it is the basis for a full estimate. Both start from the same measurements taken from the drawings.
Which takeoff do I need to bid a job?
+
To price labor, equipment and subcontract work you need a quantity takeoff. If you only need to order products from a supplier, a material takeoff is enough.
Should a takeoff include waste?
+
A material list normally includes a waste or overage factor, but it should show net quantity, the waste percentage and the order quantity separately so the assumption is visible and can be changed.
Can Bid Sharp prepare only the material list?
+
Yes. You can order a material takeoff, a full quantity takeoff with marked-up plans, or a complete priced estimate. The scope, price and turnaround are confirmed before work starts.
What do I need to send for a takeoff?
+
Send the latest drawings, specifications, addenda, the bid form and your bid due date. PDF plans are ideal; DWG, ZIP files and plan-room links also work.
