From page 47... ... While some states have fully authorized airports to use CMR and DB, there are still some states that prohibit the use of one or all alternative methods. In the spectrum between states that allow full use of alternative methods and those that prohibit them entirely, there are some states that allow alternative project delivery methods with certain conditions (e.g., requiring extra approvals, putting dollar value limits on the volume of DB or CMR contracts, or putting limits on the number of projects using an alternative delivery method each year) Read the entire page →

From page 49... ... Issue Statements Advantage Disadvantage CMR has been shown to work on projects of all sizes and levels of complexity, but the research case studies found that airports tend to select CMR on larger and more complex projects. On projects of large size and complexity, CMR can use multiple bid packages to optimize responses from proposers, but this approach results in more complexity in management. Read the entire page →
From page 50... ... Issue Statements Advantage Disadvantage DBB is the base case and will take the longest of the three delivery methods.

From page 51... ... Issue Statements Advantage Disadvantage Research on project delivery methods suggests that DBB is likely to yield the highest schedule growth due to change orders There is a lack of opportunity to compress a project schedule if problems occur due to the linear nature of DBB. Studies have shown that, on average, DBB has more schedule growth than CMR and DB. Read the entire page →
