WELCOME to PennDOT's Cost Estimating Website
cost es·ti·mate (noun) ...summation of individual cost elements, using established methods and valid data, to estimate the future costs... ...based on what is known today... (USGAO, GAO-09-3SP)
More of an art than a science, Cost Estimating requires a thorough understanding of project scope, past price history, and current market conditions along with a generous application of human judgment.
The ability to develop a reliable cost estimate is a critical function at every stage of a project. This website will serve as PennDOT's portal to essential estimating resources and information. Evolution of website content will be ongoing towards meeting the needs of the user.
Publication 352 establishes PennDOT estimating guidelines. The development of a project specific Basis of Estimate, Cost Driver Analysis, and the use of AASHTO's Estimator software is the foundation for all PennDOT estimating. This website is a tool towards facilitating a high level of estimating expertise.
