What is the template for?

When preparing an estimate in Estimator, the skeleton file template can be imported as the initial step in creating an estimate.

Why should I use the template?

The template includes standard item categories to which items, quantities, and cost estimates can be added.

Where do I find details about my project?

Project-specific details -- like key numbers and descriptions -- can be obtained from the regional specification writer.

Data used to produce estimates is stored in one or more catalogs that include item related code tables and historical item price data.

The following catalogs are made available for use in the Estimator module. These files are only useful when downloaded and used in conjunction with Estimator.

​Federally-funded projects require federal aid numbers.

Complete the Federal Aid Request Form to obtain a number for your project. Requests are generally completed within two working days.
