what is an estimator?

An estimator determines the costs involved in undertaking a project before its inception.

When bidding for a contract, a cost planner estimates the expenses for the project and the best quote.

As an estimator, you will collaborate with engineers, architects and suppliers to arrive at estimates. When coming up with a project's cost analysis, a cost planner involves all the aspects relevant to the business, including overheads, contractor's fees and timelines.
