Procedures Guide for Right-of-Way Cost Estimation and Cost Management FHWA Major Projects Cost Estimation Guidance
General Accounting Office Cost Estimating and Assessment Guide (March 2009) (PDF)
The purpose of this document is to address generally accepted best practices for ensuring credible program cost estimates (applicable across government and industry) and to provide a detailed link between cost estimating and Earned Value Management (EVM). The basic information in the Cost Guide includes the purpose, scope and schedule of a cost estimate, a work breakdown structure; ground rules and assumptions; data collection and estimation methodologies; software cost estimating; sensitivity and risk analysis; EVM and the composition of a competent cost estimating team.

Procedures for Cost Estimation and Management for Highway Projects During Planning, Programming and Preconstruction
Major Project Program Cost Estimating Guidance (January 2007)
This guidance is for the preparation of a total program cost estimate for a major project. For the purpose of this guidance, a major project is defined as a project that receives any amount of Federal financial assistance and has an estimated total program cost greater than $500 million (expressed in year-of-expenditure dollars), or other projects identified as a major project by the FHWA. The total program cost estimate includes construction, engineering, acquisition of right-of-way, and related costs, which will be identified by this guidance. Although this guidance is for major projects, it may also be applied to other projects.
Cost and Oversight of Major Highway and Bridge Projects - Issues and Options (2003) (PDF)
This document contains the highlights of GAO-03-764T, a statement for the record for the Subcommittee on Transportation, Treasury, and Independent Agencies, House Committee on Appropriations. This statement for the record summarizes cost and oversight issues raised in reports and testimonials that GAO has issued since 1995 on major highway and bridge projects and describes options that GAO has identified to enhance federal oversight of these projects.
NHI Training for Addressing Uncertainty in Cost Estimating
Offered by the National Highway Institute, this course covers the evaluation of risk and uncertainty in project cost estimates when using either a deterministic or probabilistic method. This course provides participants with an overview of current cost estimating practice and an appreciation of the importance of cost estimating. The course will compare and contrast deterministic and probabilistic methods of cost estimating, including which method is most appropriate during the various phases of project development. While this course is geared towards cost estimating for Major Projects, the concepts are applicable and scalable for developing estimates for all transportation projects.
Metroplan, the MPO in Little Rock, AR used data on petroleum prices from the Energy Information Administration and ADOT's construction cost index to develop the inflation rate for their long range plan.
Florida DOT Inflation Factor (August 2010) (PDF)
Florida DOT annually develops an inflation factor based on their highway construction cost index to be used by MPOs in developing the documents.
Ohio DOT Online Calculator (2009) (XLS)
Ohio DOT requires projects to be inflated to the mid-point of construction through an online calculator.
