CHAPTER 1 Overview Introduction and Purpose The objective of this guidebook is to help airports evaluate and choose the most appropriate project delivery method for their projects. Another important objective of this guidebook is to help airports document the process of decision-making and the outcome in a Project Delivery Decision Report. The project delivery method is the process by which a project is comprehensively designed and constructed for an owner--including project scope definition; organization of designers, construc- tors, and various consultants; sequencing of design and construction operations; execution of design and construction; and closeout and start-up. In some cases, the project delivery method may encompass operation and maintenance. Currently available project delivery methods have moved far beyond the traditional design-bid-build (DBB) method. With the change in procurement laws, public entities now share the ability of their private-sector counterparts to acquire construction services via alternative project delivery methods such as construction management, design-build, and other hybrid systems. The researchers' approach to developing the project delivery method selection system was to review and analyze relevant literature on project delivery methods and previous work in developing decision support systems for project delivery selection. The research team recently completed a similar guidebook for transit projects (Touran et al. 2009). Experience and knowl- edge gained from that research helped in streamlining the research approach used in this project. In addition, an extensive questionnaire was developed for face-to-face, structured interviews with several airports. A list of airports was developed and approved by the project oversight panel (see Table 1-1). It was decided to consider only airports that had used alterna- tive project delivery methods. Also, the team considered the geographical and capacity diver- sity of the airports to ensure that a representative sample was selected. The researchers traveled to the selected airports and interviewed persons in charge of selecting project delivery meth- ods. In almost all of the interviews, the airport was represented by a team of individuals with planning, finance, and construction responsibilities for the capital programs at the airport. The results of the interviews were then analyzed and summarized (citations to the airport interviews are given in brackets throughout this guidebook). Based on the outcome of the liter- ature search and the structured interviews, a set of pertinent issues was identified and studied. These pertinent issues are thought to have a profound effect on the choice of project delivery method. These issues in turn were used to develop the project delivery selection system described in this guidebook. 3
