What Is Material Takeoff in Construction?
If you are a general contractor, subcontractor, or builder, you have probably come across the term material takeoff in construction. But what exactly does it mean, and why is it so important when preparing a construction bid?
A material takeoff is one of the first steps in the construction estimating process. It helps determine exactly how much material a project requires before those quantities are priced and included in the overall estimate.
In this guide, we’ll explain what a material takeoff is, what it includes, how professional estimators prepare one, and how accurate quantities can help contractors make better bidding and purchasing decisions.
Quick Answer
A material takeoff—also called a quantity takeoff or construction takeoff—is the process of reviewing construction drawings and measuring or counting the materials required to complete a project.
Depending on the project, this may include concrete, framing lumber, drywall, roofing, flooring, paint, doors and windows, electrical components, plumbing fixtures, HVAC materials, and other trade-specific items.
Why Is Material Takeoff Important?
Accurate quantities can make a significant difference during both bidding and project planning.
Whether you’re preparing a residential project in the USA, a commercial tender in Australia, or a subcontractor bid for a specific trade, reliable quantity information gives you a stronger foundation for pricing.
Without an Accurate Takeoff
- Material quantities may be based on guesswork
- Important scope items can be missed
- Bids may be too high or too low
- Supplier pricing can be based on incomplete information
- Material shortages can cause delays
- Excess materials can increase waste and project costs
With an Accurate Takeoff
- Quantities are based on the actual drawings
- Bids can be prepared using better cost information
- Supplier quotes can be requested using clear quantities
- Material ordering becomes more organized
- Potential scope gaps can be identified earlier
- Project planning becomes easier
An accurate takeoff doesn’t guarantee that a project will be won or remain within budget, but it gives contractors much better information on which to base their decisions.
What Does a Material Takeoff Include?

How Is a Material Takeoff Done?
A professional estimator generally follows a structured process when preparing a takeoff.
1. Review the Project Drawings
The process begins with the available project documents, including architectural plans, structural drawings, MEP drawings, details, schedules, and specifications.
2. Confirm the Drawing Scale
The estimator checks the drawing scale and calibrates the takeoff software when digital measurement tools are being used.
This step is essential because incorrect scale settings can result in incorrect quantities.
3. Identify Materials
The estimator reviews the drawings, legends, schedules, and specifications to determine which materials are required.
4. Measure and Count
Areas, lengths, volumes, and individual units are measured or counted using digital takeoff software or other appropriate methods.
5. Review Waste Allowances
Some materials require additional allowance because of cutting, offcuts, breakage, installation conditions, or the layout of the project.
Waste allowances should be based on the material and project requirements rather than applying one percentage to everything.
6. Organize the Quantities
Quantities are grouped by trade, material, and project scope so they can be easily reviewed and priced.
7. Prepare the Takeoff Report
The final quantities are presented in an organized format, commonly through an Excel spreadsheet or estimating software output.
Material Takeoff vs. Cost Estimate: What’s the Difference?
Material takeoff and cost estimating are closely related, but they are not the same thing.
The simplest way to understand the difference is:
Material Takeoff = How much material is required?
Cost Estimate = How much will the project cost?
A material takeoff focuses on quantities such as square feet, linear feet, cubic yards, units, sheets, or gallons.
A cost estimate takes those quantities and applies pricing for materials, labor, equipment, subcontractors, and other project costs.
Material Takeoff
- Lists required quantities
- Measures and counts materials
- Generally does not include dollar values
- Provides information for suppliers and estimators
- Comes early in the estimating process
Cost Estimate
- Applies unit prices
- Includes material and labor costs
- Can include equipment and subcontractor costs
- Produces projected project costs
- Uses takeoff quantities as a key input
A reliable cost estimate depends heavily on having reliable quantities to price.
What Software Is Used for Material Takeoffs?
Professional estimators use a range of digital tools to measure quantities from construction drawings.
Some commonly used tools include:
PlanSwift
PlanSwift is widely used for digital construction takeoffs and provides tools for measuring areas, lengths, and quantities from drawings.
Bluebeam Revu
Bluebeam Revu provides PDF markup and measurement tools that can be useful for reviewing drawings and performing digital takeoffs.
On-Screen Takeoff
On-Screen Takeoff is another estimating and takeoff platform commonly used for construction bidding and quantity measurement.
Microsoft Excel
Excel is frequently used to organize, review, calculate, and present takeoff quantities in a structured format.
The best software depends on the project type, workflow, estimator’s experience, and the information available in the drawings.
Waste Factors in Material Takeoff
Waste is another important consideration when preparing a material takeoff.
Materials may require additional quantities because of cutting, offcuts, breakage, installation methods, or project-specific conditions.
For example, the appropriate allowance for flooring or tile may depend on the room layout and installation pattern, while sheet materials may require allowances based on cutting and panel sizes.
Rather than applying one blanket percentage to every material, professional estimators should consider the specific material and project requirements when determining waste allowances.
Frequently Asked Questions About Material Takeoffs
How long does a material takeoff take?
The time required depends on the project size, drawing quality, number of trades, and level of detail required.
A simple single-trade takeoff may take only a few hours, while a full-scope residential or commercial takeoff can take significantly longer.
Can I outsource a material takeoff?
Yes. Contractors and builders can outsource material takeoff work to professional estimating companies or independent estimators.
Outsourcing can save internal staff time and provide organized quantity information that can be used for bidding and procurement.
How accurate is a material takeoff?
Accuracy depends on the quality of the drawings, project documentation, measurement methods, estimator experience, and scope of the takeoff.
A professional takeoff should always be reviewed against the available drawings and specifications before quantities are used for purchasing or final project decisions.
What files are needed for a material takeoff?
Most takeoff work is performed from PDF construction drawings. Depending on the project, CAD files such as DWG or DXF files, specifications, schedules, and other project documents may also be useful.
Clear and complete project documentation generally produces a better basis for quantity measurement.
