Synthesis of Information Related to Highway Practices. Topic 54-16. Post-Construction Evaluation Practices for Highway Projects Delivered Using Alternative

Alternative contracting methods (ACMs) are defined as the realm of contract payment provisions, procurement procedures, and various types of project delivery methods that supplement traditional low-bid, design-bid-build contracting. The potential benefits of using ACMs includes reducing project delivery duration, reducing operational and life cycle costs, improving quality and constructability, earlier contractor engagement, promoting innovative thinking to produce outside-the-box solutions, improving risk allocation strategies, and allowing for alternative financing solutions. The Federal Highway Administration has evaluated the performance of the three most commonly used project delivery methods (design-bid-build, design-build, and construction manager/general contractor) using a comprehensive dataset of 291 completed highway projects. The study outcome resulted in the creation of numerous guidelines at the state and federal levels to assist agencies in selecting the most appropriate project delivery method for a project given its current goals, resources and constraints. An example on the federal level is the AASHTO Alternate Contracting Method Guideline, which was developed to provide guidance and aid in selecting the most appropriate ACM. On the state level, several departments of transportation (DOTs) have developed their own guidelines and ACM selection tools. However, there is very little information or guidance about looking back after a project is complete and evaluating the project delivery method decision that was made and the benefits that accrued from the decision. The objective of this synthesis is to document current state DOT practice for evaluating the outcome of the ACM processes after project completion. The synthesis will address the ACM selection process in its entirety, including the project delivery method, procurement procedure, and contract management methods.
