Synthesis of Information Related to Highway Practices. Topic 54-12. Programmatic Implementation of Alternative Delivery Methods by State Transportation Agencies

Alternative Delivery Methods (ADMs), including Design-Build (DB), Construction Manager/General Contractor (CM/GC), Public-Private Partnerships (PPP), and other combinations that may include Operations and Maintenance, have added a wide range of options for state transportation agencies to consider when delivering projects. Agencies have traditionally used the design-bid-build (DBB) method, by awarding a contract for construction to the lowest bidder, based on agency-designed plans. After many generations of use, the DBB delivery method is so engrained in local, state, and national agency processes, standards, and contracts that agencies are organized around this one delivery model. Implementing ADMs warrants different mindsets and approaches to processes, standards, risk allocations, and contracts to reach successful project outcomes. Most state transportation agencies across the country have used at least one form of ADM to deliver, operate, or maintain their transportation facilities. While some agencies have focused on a single project to test an ADM, or have developed each ADM project on an individual or one-by-one basis, other agencies have developed agency-wide programmatic approaches to build consistency when implementing ADMs across multiple projects or regions. ADM procurement and implementation disrupt the traditional DBB project development and contracting processes. As agencies try to adapt to maximize the value of ADMs, they can find that even their organizational structures, built around traditionally discrete and distinct areas of professional expertise, must be reimagined. These agencies have had to rethink administrative processes and procedures, each developed over decades to accommodate the DBB delivery method, to be tailored to function successfully and sustainably in this evolving and dynamic environment of multiple delivery method options. Agencies that have implemented more than one ADM project have discovered the importance of building consistency from one ADM project to the next ADM project, much like the DBB practices now considered standard. This consistency brings greater efficiency and familiarity for agency staff, stakeholders, and industry participants. But whether and how an agency chooses to establish a programmatic approach to implementing ADM projects varies from one state to the next. The objective of this synthesis is to document state DOT current practices of programmatic approaches to ADMs. Information to be gathered includes (but is not limited to): (1) Which DOTs have implemented programmatic approaches to using ADMs; (2) Organizational changes by DOTs utilizing programmatic approaches; and (3) Factors agencies considered for implementing programmatic approaches to ADMs.
