(1) “Authorized contingency” means the contingency prepared and submitted by the CM/GC as part of the GMP, which is designed to cover costs that may result from incomplete design, unforeseen and unpredictable conditions, or uncertainties within the defined project scope which a prudent CM/GC would not have reasonably detected or anticipated during the discharge of CM/GC's pre-construction duties;

(3) “Construction manager/general contractor” or “CM/GC” means a business firm or joint venture, separate from the project designer, that is able to provide pre-construction services during the design and development phase of a transportation project, including, but not limited to, constructability review, scheduling, pricing, and phasing, and is able to construct the project if the department and firm or joint venture agree to a guaranteed maximum price;

(4) “Construction manager/general contractor method” or “CM/GC method” means a project delivery method in which a construction manager is procured to provide pre-construction services and the CM/GC may subsequently construct the project, or any part of the project, if the department and the firm reach agreement on a guaranteed maximum price;

(10) “Progressive design-build method” or “PDB method” means a transportation project delivery method in which the department procures a design-builder to provide pre-construction services and may subsequently complete the final design and construct the project, or part of the project, if the department and the design-builder reach agreement on a guaranteed maximum price.
