A quantity takeoff is the measured list of materials, items and work sections needed to price a construction project. It is usually taken from drawings, schedules and specification notes before rates are applied.
For builders, the takeoff is where many pricing problems either get caught or carried forward. Missed openings, build-ups, preliminaries, waste allowances, drainage runs, external works or specification gaps can all make a quote look fine on paper while the job is still underpriced.
If you need a measured takeoff or BOQ-style breakdown from drawings, Cost Estimator can help through BOQ estimating support for builders. For a deeper builder-focused guide, read what gets missed in takeoffs before the quote goes out.
What a quantity takeoff includes
- Measured quantities for materials, items and work sections.
- Units such as m², m³, linear metres, item counts and provisional allowances.
- Descriptions that explain what has been measured and what assumptions sit behind it.
- Notes on gaps, exclusions or details that need checking before pricing.
Quantity takeoff vs bill of quantities
A quantity takeoff measures the work. A bill of quantities organises those measured quantities into a document that can be priced, reviewed and used for tendering or quote comparison.
On smaller jobs, a measured estimate with clear assumptions may be enough. On tendered or higher-risk work, a fuller BOQ-style structure can make the pricing basis easier to check.
When builders should use takeoff support
Takeoff support is useful when the drawings are detailed enough to measure, the quote carries margin risk, or the job needs a cleaner pricing basis before it goes to the client. It is especially useful for extensions, refurbishments, new builds, groundworks packages and tender work where small scope gaps can quickly become expensive.
You can upload plans for review if the job needs fuller estimating support, or use Quick Quote when the scope is clear and you want to book professional estimating work quickly.
