AI takeoff — common questions
What is AI takeoff software?
AI takeoff software reads your construction drawings automatically instead of you measuring everything by hand. TradeOff detects the drawing scale, extracts quantities from schedules and legends, and counts repeated symbols — giving you a first-pass takeoff in seconds that you review and refine.
How accurate is the AI takeoff?
TradeOff's AI is a fast first pass, not a black box. Every quantity, count and suggested rate is shown for you to review and edit before it hits your estimate, so you stay in control of the numbers you send to a client.
Can AI price my estimate too?
Yes. Extracted quantities are matched to your own rate library with a confidence score and adjusted to your pricing region, so you get a priced estimate — not just quantities — that you can tune before sending.
Do I need to calibrate the scale manually?
Usually not. AI reads the scale from the title block (e.g. 1:100). You can always override it, but for most drawings you can start measuring straight away.
Can I do a takeoff from my phone?
Yes. Snap a photo of a drawing or schedule on site and TradeOff's AI returns quantities you can turn into a priced estimate — handy when you're on the job without a laptop.
Is it built for UK subcontractors?
Yes. TradeOff is made for UK subcontractors — AI takeoff and estimating flow straight into Applications for Payment with CIS deductions, VAT domestic reverse charge and Xero sync built in.
