Estimators work on construction projects to predict the cost of the project. An estimator breaks down a project into its individual components, like the cost of the materials or the labor, and creates an overall estimate for how much a project will cost. An estimator apprentice will conduct research on the cost of materials, subcontractor service costs, and labor costs. An estimator may help other teams create a project proposal, seek to understand a customer's needs, track project costs, create a budget, or analyze a completed project's costs. To learn the role, estimator apprentices will spend part of the apprenticeship performing building and construction functions.
