72 A Guidebook for Selecting Airport Capital Project Delivery Methods Design-Build (DB) Please specify procurement system: (____________________________________) Issue Statements Advantage Disadvantage The single source for design and construction eliminates claims for design errors or omissions from the airport's perspective. There is a potential for claims with regard to scope definition if the form of the DB contract is not well understood. The size and frequency of change orders are smaller in DB. Table 4-22. Construction claims advantages/ disadvantages summary. Issue DBB CMR DB 19. Construction Claims Key: Most appropriate delivery method Appropriate delivery method Least appropriate delivery method X Not applicable (discontinue evaluation of this method) Comments ____________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ Step 5. Choose the Most Appropriate Project Delivery Method Steps 1 through 4 of the selection process provide all the individual pieces of information to make a project delivery decision. The final step involves combining this information into a final comprehensive format that will aid in making the decision. Table 4-23 presents a form in which to summarize the advantages and disadvantages of each project delivery method with regard to each of the issues. Step 5 requires the following actions: Review project goals. Review the project goals documented in Step 2 to be certain that any project delivery method selection is in alignment with these goals. Transfer issue summary ratings. Transfer each of the 19 individual issue summary ratings (documented in the Issue Summary Table at the end of each issue analysis) to Table 4-23 to provide a complete picture of the analysis. Review Table 4-23 to determine the dominant delivery method. Upon completion of Table 4-23, a delivery method may emerge as dominant. A dominant delivery method will contain a large number of "most appropriate" ratings in areas that align with the project goals. A dominant method will also have few or no "least appropriate" ratings. Counting or trans- lating the ratings should be avoided. If needed, review any comments from the pertinent issue analysis (see Chapter 3) to help with the delivery decision. Note: If a dominant method exists, make a project delivery choice and move to Step 6.
