CHAPTER 4 Tier 1--Analytical Delivery Decision Approach Introduction No single project delivery method is appropriate for every project. Each project must be exam- ined individually to determine how it aligns with the attributes of each available delivery method. The Tier 1--Analytical Delivery Decision Approach (Tier 1 approach) provides airports with a structured approach to choosing the most appropriate project delivery method for an individ- ual project. The Tier 1 approach has three primary objectives: Present a structured framework to assist airports in examining 19 pertinent issues involved in the project delivery decision, Assist airports in determining whether there is a dominant or obvious choice of project deliv- ery method, and Provide a structure for documenting the project delivery decision in the form of a Project Delivery Decision Report. The Tier 1 approach provides a framework for airports to use in defining project goals and examining the advantages and disadvantages of each delivery method within the context of these goals. The aim of this approach is to help airports understand project delivery method attributes and determine whether their specific project goals align with the attributes of a particular deliv- ery method. The Tier 1 approach also provides a go/no go review to determine whether one or more project delivery methods should be excluded from the examination. At the completion of the Tier 1 approach, there is a possibility that an airport may not have one clear and logical choice for a project delivery method. If this is the case, the airport is advised to move on to the Tier 2 approach with the best delivery method options yielded from the appli- cation of the Tier 1 approach and create a more detailed analysis to select the final project deliv- ery method. The Tier 1 approach includes six distinct steps listed below and shown in Figure 4-1: Step 1. Create Project Description Step 2. Define Project Goals Step 3. Review Go/No-Go Decision Points Step 4. Review Project Delivery Method Advantages and Disadvantages Step 5. Choose Most Appropriate Project Delivery Method Step 6. Document Results The objective of Step 1 is to create a project description in sufficient detail for documenting the project delivery decision. A template is provided to assist airports in describing the appropri- ate level of detail (please see Appendix C, available on the TRB website. Go to and search for "ACRP Report 21"). The description is provided to summarize only the key variables 40
