    The model then provides as output various resources requirements in cost and time. Some models concentrate only on estimating project costs (often a single monetary value). Little attention has been given to the development of models for estimating the amount of resources needed for the different elements that comprise a project. [1]

    They are developed by an estimator during the pre-construction phase. This process includes breaking the project down into smaller and more manageable units that are easier to measure or estimate. The level of detail required for measurement may vary. [1] These measurements are used to format a bid on the scope of construction.
