What are the Main Duties of a Project Estimator?

Answer 1

Usually a project estimator's job is to perform calculations and draw an accurate guess of about how much a project will cost, or how much time it will take, or how much of what materials are needed. It all depends on what the estimator is estimating.

Answer 2

Estimating the costs associated with producing the project. It might be a good idea if you knew Cost Accounting. I would also be a good idea if you were able to aquire or create a Bill of Materials. Do not forget to include esitmates of total plant resources aka overhead to the project estimate.
