# Material Takeoffs & Quantity Estimation
Material takeoffs are one of the most time-consuming parts of bidding and planning a job. Counting every outlet, measuring every pipe run, and tallying every sheet of drywall takes hours of careful work. AI can dramatically speed up this process by analyzing plan sheets and generating preliminary quantity lists.
How AI Handles Takeoffs
When you upload a plan sheet and ask for a material takeoff, AI processes the drawing by:
- 1.Identifying symbols — counting fixtures, devices, and equipment
- 2.Measuring runs — estimating linear footage of pipe, conduit, or ductwork based on the scale
- 3.Reading specifications — pulling material types and sizes from notes and callouts
- 4.Applying basic rules — adding waste factors, accounting for standard fitting patterns
