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 transit agencies with a structured approach to choosing the most appropriate project delivery method for an individual project. The Tier 1 approach has three primary objectives: Present a structured framework to assist agencies in examining 24 pertinent issues involved in the project delivery decision, Assist agencies 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 agencies 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 agencies understand project delivery method attri- butes and to help them determine whether their specific project goals align with the attributes of a particular delivery method. The Tier 1 approach also provides a "go/no go" review to deter- mine 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 agency may not have one clear and logical choice for a project delivery method. If this is the case, the agency will be advised to move to the Tier 2 or Tier 3 approaches with the best delivery method options yielded in the application of the Tier 1 approach and create a more detailed analysis to select the final project delivery 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 agencies in describing the appro- priate level of detail. The description is provided to summarize the key variables and provide a "snapshot" of the project scope at the time when the project delivery decision was made. 41
