How is quantity takeoff done?

Traditionally, quantity takeoff is done by manually measuring quantities from blueprints and recording them in a spreadsheet. With AI quantity takeoff, the blueprint is uploaded to the software, which identifies building components and calculates quantities automatically in seconds.

What is the difference between quantity takeoff and quantity calculation?

Quantity takeoff and quantity calculation essentially mean the same thing. Quantity takeoff specifically refers to measuring and identifying from blueprints, while quantity calculation covers the broader process from reading blueprints to producing a complete bill of quantities.

Automatic quantity takeoff — AI reads blueprints and calculates quantities

Quantity takeoff is the most critical and time-consuming phase of a construction project. Massoi automates it with AI — upload a blueprint and get accurate quantities in seconds.

What does quantity takeoff mean?

Quantity takeoff (calculating quantities from blueprints) is the process of extracting all material quantities from construction blueprints: square meters, linear meters, cubic meters, and unit counts. It is the foundation of bid calculation and cost estimation.

Traditionally, quantity takeoff is done by manually measuring blueprints with a ruler or CAD software. A single apartment building project can require hundreds of work hours just for quantity takeoff. Errors compound throughout the project and can lead to significant financial losses.

Massoi's AI-powered quantity takeoff changes this. AI reads the blueprint, identifies building components, and calculates quantities automatically — in seconds, not hours.

Why is quantity takeoff a bottleneck?

Time-consuming

Traditional quantity takeoff takes 60–80% of the entire bid calculation time. A single apartment building project's takeoff can take weeks.

Error-prone

When calculating by hand, errors are inevitable. Studies show manual quantity takeoff has an average 5–15% error margin.

Costly mistake

Incorrect quantity takeoff leads to over- or under-pricing. A bid that's too low eats the margin, a bid that's too high loses the contract.

How automatic quantity takeoff works

1. Upload a drawing

Drag and drop a PDF, DWG, or IFC file into Massoi. Also supports photos and scanned blueprints.

2. AI analyzes

AI identifies building components, dimensions, and materials automatically. No manual tracing.

3. Quantities are calculated

AI calculates areas, lengths, volumes, and unit counts for each building component.

4. Review and export

Review results visually, make changes as needed, and export to Excel or bid template.

AI quantity takeoff accuracy and reliability

Massoi's AI is trained on thousands of construction blueprints. It identifies walls, windows, doors, tiles, HVAC components, and structural layers automatically.

AI doesn't replace the professional — it eliminates repetitive manual work. You can always review and edit results before creating a bid. Every identified component is traceable to the original blueprint.
