Takeoff
Quantities read off the drawings. Everything downstream — the quote, the progress claim, the crew's pay — is computed from this table and nothing else.

An estimator checks the assumptions before the arithmetic
Demo takeoff. Reviewed and accepted by estimator; imaging suite lead thickness still outstanding with the architect.
