Key Project Factors of Construction Time and Cost Performance during Incentive/Disincentive Highway Projects

摘要

The Federal Highway Administration has encouraged the State Transportation Agencies to implementIncentive/Disincentive (I/D) contracting designed to minimize the disruption of traffic flow in highway construction projects.However, there is little understanding about project factors that affect the project time and cost performance of highway constructionprojects under I/D provisions. This paper presents key project factors that affect project time or cost performance during I/D highwayconstruction projects. First, this research was performed by collecting transportation construction project data from the FloridaDepartment of Transportation and evaluating the data using time and cost performance indices. Then, statistical analyses wereperformed to identify any differences in project performance among project variables. Finally, significant factors that influence projectperformance were identified and summarized.
