From page 49... ... While some states have fully authorized transit agencies to use CMR, DB, and DBOM, there are still some states that prohibit the use of one or all alternative methods. Along with states that allow full use of alternative delivery methods and those that prohibit the use of all or some of the alternative delivery methods, there are states that allow alternative project delivery methods as long as certain conditions are met (e.g., requiring extra approvals for projects with alternative delivery methods, putting dollar value limits on the volume of DB or CMR contracts that a state may authorize, or putting limits on the number of projects using an alternative delivery method that a state may authorize each year) Read the entire page →
