As a construction project proceeds, we often see the people who do the "heavy lifting" that brings together the final product. However, a key player in that process is the cost estimator.

Accurate estimating is critical in order to be sure a project, whether it's the construction of a skyscraper or production of a line of toys, meets the owner's fiscal and production.

These professionals work with owners, architects, engineers and contractors to provide not only estimates throughout the different stages of a project, but cost saving recommendations and construction/manufacturing scheduling. As work proceeds they also identify cost overruns and suggest corrective actions.

Approximately 60 percent work in the construction industry, although the job description is similar in other industries, such as manufacturing. They must compile and analyze elements that effect construction costs such as labor, materials, location, and equipment needs.

In construction, the estimator's work helps determine whether or not a company will bid on a project and, if so, how much it will be. The process begins with a review of architects' drawings and other documents listing project specifications.

Next they visit the proposed site and compile a written report on other factors affecting cost such as site access, utility services, surface topography and drainage.

The cost estimator then compiles a quantity survey, which indicates the amounts of labor and materials that will be needed, by completing forms that require standard information such as dimensions, costs of items the contractor will have to provide, and potential costs of subcontractors.

After finishing the quantity surveys, a total project cost summary is prepared by the chief estimator and used as the basis for the bid proposal which is submitted to the developer.

It is essential that cost estimators have not only good math skills, but be able to communicate their conclusions to the project team. Being adept with computerized spreadsheets and specialized estimating software is also a must. Computers have become a large part of the process, not only for complex math calculations, but because they provide quick access to databases of information on costs and conditions of similar projects.

According to a 1997 survey from the National Association of Colleges and Employers, those with bachelor's degrees in construction science received starting offers averaging $31,949. Those with the most experience earned more than $75,000 annually.
