Definition
A hybrid contract type using fixed unit rates with an open-ended quantity, often with a not-to-exceed ceiling.
Time and Materials (T&M) in plain English
Not every building needs the same construction method: a bridge wants heavy upfront engineering; a mobile app wants short feedback loops; many real jobs mix both. Time and Materials (T&M) is about matching the delivery style to uncertainty and stakeholder need — not forcing one religion on every project. Hold onto this precise job description: A hybrid contract type using fixed unit rates with an open-ended quantity, often with a not-to-exceed ceiling. On a stem, name whether Time and Materials (T&M) is about timing, ownership, measurement, or delivery style — then eliminate the answer that borrows a cousin concept from the wrong phase.
