Update of the AASHTO Practical Guide to Cost Estimating (PGCE)

  Project Data
Source: Louisiana Department of Transportation
Funds: $250,000
Staff Responsibility: Christopher T. McKenney
Fiscal Year: 2023

This project has been tentatively selected and a project statement (request for proposals) is expected to be available on this website. The problem statement below will be the starting point for a panel of experts to develop the project statement.

The PGCE provides state departments of transportation (DOTs) as well as other transportation agencies with practical guidance on how to develop realistic estimates of project costs. The original PGCE was published in 2013 and since then, newer means and methods of estimating have been identified and need to be considered. The guide also needs to be updated to address estimating as it applies to the newer alternative delivery methods. In addition, various software references, tools, website links, charts, and tables need to be updated to maintain the PGCE’s relevance to current cost estimators. The PGCE is also the foundation for training, such as that provided by the AASHTO Technical Committee on Cost Estimating (TCCE) and Risk-based Estimating Training sponsored by the Federal Highway Administration (FHWA). Research is needed to help transportation agencies successfully manage and deliver their programs by providing them with the necessary guidance to develop consistent and reliable cost estimates.

The objective of this research is to produce a new edition of the PGCE. Potential tasks may include (1) identifying current state-of-practices of state agencies, relevant research in cost estimating, and regulatory or other compliance information relevant to industry practice; (2) identifying new material and training that can be incorporated such as terminology, charts, references, methods, etc.; and (3) consideration or commentary regarding estimating project costs when projects are delivered using alternative project delivery methods.
