How is quantity calculation done from PDF drawings?

Quantity calculation from PDFs is done either by manual measurement in a PDF reader or by using an AI tool like Massoi. AI identifies building components automatically and calculates areas, lengths and piece counts in seconds.

What is the difference between quantity calculation and quantity takeoff?

Quantity calculation and quantity takeoff essentially refer to the same process. Takeoff specifically refers to measuring from drawings, while quantity calculation covers the entire process from measurement to a finished quantity list used in pricing, procurement and scheduling.

How does AI speed up quantity calculation?

AI reads the drawing, identifies building components (walls, windows, doors, floors, etc.) and calculates quantities automatically. The process takes minutes, while traditional manual calculation takes hours or days.

Quantity Calculation — accurate quantity lists for bids and procurement

Quantity calculation produces accurate material and labor quantity lists for pricing, purchasing and scheduling. Massoi automates the entire process from drawings to a finished list.

What is quantity calculation?

Quantity calculation (quantity takeoff) means calculating the quantities of building materials and work from drawings and plans. It is the starting point for every bid, cost estimate and procurement list.

While quantity takeoff focuses on reading the drawing and identifying building components, quantity calculation produces the end result: an itemized list of materials, labor quantities and units used in pricing, procurement and scheduling.

Massoi's AI automates both steps. Upload a drawing and get a ready-made quantity list from which you can proceed directly to pricing or export the data to Excel.

How does AI do quantity calculation?

Reading the drawing

AI reads PDF, DWG and IFC files as well as scanned drawings. The AI identifies the scale and drawing type automatically.

Component recognition

The neural network identifies walls, windows, doors, floors, ceilings, pipes, ducts and other building components. Over 50 different component types.

Quantity calculation

AI calculates areas, lengths, volumes and piece counts for each identified building component. Results are dimensionally accurate.

Reporting and export

Results are compiled into a clear quantity list. Export to Excel, continue to pricing or create a bid directly in Massoi.
