A construction estimator gathers, analyzes, and prepares detailed total cost information to maximize cost-effectiveness during the construction process. They visit construction sites to gather necessary client requirement information and analyze proposals, specifications, blueprints, and construction documents to thoroughly understand the project. They work closely with construction project managers to coordinate and oversee the vendors and subcontractors bid process. The construction estimator then determines the time, labor, construction materials, and product costs for construction projects and communicates these requirements to clients. A construction estimator works in an office environment, with occasional construction site visits, and typically works with construction and development companies.
