Worked example

An example take-off

Illustrative example, assembled to show the result format. The drawing is invented and the schedule was written by hand, not produced by the tool. Your own drawing may give different or incomplete results.

The windows and doors are counted from their tags and pass the tool’s checks. The brickwork and the plinth are measured and held back as candidates, with the reason given. The plinth is shown as a length because this key lists it as a course; the right unit and description depend on what the take-off is for and the measurement rules the job uses.

A gap is not a zero. These were noticed and have no quantity here. The list may not be complete: the tool cannot tell you everything it missed.
