Therefore, the reader should understand the results of the research reported herein as evidence that a given project delivery method may be used successfully on a specific set of projects, not as evidence that any particular project delivery method is inherently superior to all others. Before describing various project delivery methods, it is important to note the features of major transit projects that distinguish them from other transportation projects.

These characteristics of transit projects drive the need for a "toolbox" of project delivery methods that permits a transit agency to select the appropriate project delivery "tool" based on the technical demands of a given project. Transit projects are not usually money makers (unlike some toll roads in the highway sector)

to award DB contracts if the enabling state-level legislation was in force. Subsequent to the successful use of DB in several projects, many states passed new legislation and codes to allow alternative project delivery methods, i.e., DB and CMR.

DBB is the traditional project delivery method. In this method, an owner retains a designer to furnish complete design services and then advertises and awards a separate construction contract that is based on the designer's completed construction documents.

Finally, as DBB is generally viewed as the traditional project delivery method in the United States, it is well understood and accepted by owners and members of the design and construction industries. CMR or Construction Manager/General Contractor (CM/GC)

Our emphasis in this work is CM at-risk. Agency CM is not a project delivery method because the CM is not contractually responsible for delivering the project.

As in CMR, the builder has early constructability input to the design process. As the owner no longer owns the details of design, the owner's relationship with the 14 A Guidebook for the Evaluation of Project Delivery Methods (Adapted from American Institute of Architects 1996.)

Developing pilot programs is a common approach in some states for implementing previously unauthorized project delivery methods, particularly DB. In order to update information on the legal status of alternative project delivery methods in various states, a thorough literature search was conducted on the laws of all 50 states.

Existing Selection Approaches for Project Delivery Methods Selection of the appropriate alternative project delivery method is a complex decisionmaking process. The decision should be made as early in the design phase as possible, preferably in the project scoping process and certainly before the final construction estimates for the project are ready.

. Additionally, a recent NCHRP study of best value contracting also furnished a direct comparison of the performance of transportation project delivery methods (Scott et al.

In summary, the existing body of knowledge in the area of project delivery, along with specific information collected on transit projects during interviews, provides a solid foundation for developing a new selection system for project delivery methods that is tailored to the needs of transit owners. Timing of Project Delivery Method Selection Transit projects, especially those that receive federal funds, follow several steps during their development.
