NCHRP Project 20-24(37) activities are undertaken generally to support development of a commonly accepted set of measures state departments of transportation (DOTs) would use to assess system and agency performance; a single common data standard for each measure; a simple and reliable data submission process; and a basis for identifying, validating, and sharing best management practices that support high performance. Studies of specific aspects of performance entail comparison of data provided by several states and documentation of practices underlying best performance among participating states.
The initial study under the NCHRP 20-24(37) series collected data from 20 states to represent cost- and schedule-compliance measures, in effect responses to two simple questions: “Was the project built for the expected cost” and “Was the project built on the expected schedule?” Data supplied by state DOTs was reviewed to ensure “apples to apples” comparisons. The comparisons were made by the research team and results presented to maintain DOT anonymity. Identities of agencies found to represent superior performance were revealed with those agencies’ permission. The results of this initial project, NCHRP 20-24(37)A, was the basis for identifying 28 best practices from 9 states with respect to construction project cost and schedule performance. The project also served as a “proof of concept” that motivated subsequent work in the 20-24(37) series.
The objectives of this project are to (a) update the comparative analysis of DOT performance regarding construction project cost and schedule, (b) expand that analysis to incorporate more of the nation’s DOTs, and (c) report on successful techniques employed by leading agencies. While the techniques developed in the initial NCHRP 20-24(37)A may be employed to make this update, this study will give attention also to creating a data specification and data submission process to support on-time and on-budget project delivery measurement across DOTs.
The initial NCHRP 20-24(37)A project was completed in 2007. The research agency's final report of that 1st phase is available at this link 20-24(37)A Final Report AASHTO’s leadership believe that periodic updates and extensions of that study will help DOTs both to assess the effectiveness of their efforts to control project delivery time and cost variances and to participate more effectively in discussions related to evolving national transportation program management policy. A second analysis was completed in 2011. The final report of that work is available for download by clicking here.
