Industries & Professions /
In the construction industry, the nature of the work is largely determined by the type and size of the project being estimated. For a large building project, for example, the estimator reviews architectural drawings and other bidding documents before any construction begins. The estimator then visits the potential construction site to collect information that may affect the way the structure is built, such as the site's access to transportation, water, electricity, and other needed resources. While out in the field, the estimator also analyzes the topography of the land, taking note of its general characteristics, such as drainage areas and the location of trees and other vegetation. After compiling thorough research, the estimator writes a quantity survey, or takeoff. This is an itemized report of the quantity of materials and labor a firm will need for the proposed project.
