78 A Guidebook for Selecting Airport Capital Project Delivery Methods Are there goal statements missing that are needed to define the ultimate project success? Can any of the goals be stated more concisely? The Tier 1 approach provides an opportunity to review 19 pertinent project delivery issues. However, in the Tier 1 approach, all of the issues are treated as equally important. Upon reviewing the issues, airports will certainly find that some issues are more important than others. A small number of issues are likely to be important to the final project delivery decision. The next task in Step 1 is to select up to 7 of the 19 pertinent issues to examine and develop into selection factors. The airport should select the pertinent issues based on the following criteria: The pertinent issues should be independent of the project goals, The pertinent issues should be independent of each other, and No more than seven critical issues should be chosen. The final task of Step 1 is to consolidate the goals-based and issues-based selection factors into one comprehensive list. The intent is to limit the total number of selection factors in this con- solidated list to seven, so depending on the number of goals chosen, some of the pertinent issues may be eliminated in the final analysis. Delivery Selection Process for the Example Project--Step 1. The selection factors for the example project were determined to be the following: Project complete by November 1, 20XX. Cost not to exceed $200 million. Minimize impact on operations and passengers. Minimize staffing requirements during design and construction. This list of selection factors includes project goals relating to time, cost, operations, and staffing. While other issues of technical quality, maintainability, security, and so forth, undoubt- edly exist on the project, the list of selection factors includes the goals and issues by which the success of the project will be primarily measured at its completion. Step 2. Weight Selection Factors The Tier 2 approach is based on the premise that airports can establish a unique hierarchy of selection factors. In other words, success will be defined differently for each project and the cri- teria for success can be described by a few key selection factors. The objective of Step 2 is to weight the list of selection factors. Step 2 involves first ranking and then weighting the selection factors. There are numerous meth- ods that can be used to achieve a weighted ranking of the factors. The most straightforward method is developing a ranking and weighting through discussion among project decision-makers. The decision will by nature be somewhat subjective, so a diligently documented group decision is preferable. To achieve the weighted ranking, airports should do the following: List the selection factors in rank order from highest to the lowest with regard to their influ- ence on project success. Include a minimum of four and a maximum of seven factors. Remove factors not ranked in the top seven. Using 100 total points, weight the factors according to their influence on project success. Avoid equal weighting of factors. Remove any factors with a value of less than 5 of the 100 points and redistribute points.
