Time and Material (T&M) pricing in the construction management world refers to a type of project in which workers are paid based on how much time is spent in addition to the cost of the materials and overhead expenses utilized on the project over time, as opposed to one fixed price for the completed job. While the T&M model can be extremely beneficial when working on a large project with an unforeseeable end, it only pays off when you’re able to organize and accurately keep track of everything used and the time it took to use it.
