(a) Notwithstanding another law to the contrary, the department is authorized to use the construction manager/general contractor (CM/GC) method and progressive design-build (PDB) method as delivery methods for procuring transportation project services.
PDB: means a design-builder that is able to provide pre-construction services during the preliminary design and development phase of a transportation project, including, but not limited to, constructability review, scheduling, pricing, and phasing, and is able to complete the final design and construct the project if the department and the design-builder agree to a guaranteed maximum price. See Tennessee Code 54-1-502
(b) The department shall select CM/GC and PDB projects based upon generally accepted industry criteria that include factors such as fostering innovation, mitigating risk, improving design quality, improving cost control, and optimizing construction schedules.(c) Types of projects suited for CM/GC and PDB methods include, but are not limited to, instances where the department needs feedback during the design phase due to complex components that require innovation, projects that have public involvement, projects that have third-party considerations such as acquisition of right-of-way or utility relocation issues, or situations where other factors impact the overall schedule. Types of projects not suited for the CM/GC or PDB methods include, but are not limited to, routine maintenance and resurfacing projects or other construction projects that present a low level of technical complexity, a low level of risk management, and simple traffic phasing, and that do not have a compelling need for project acceleration.
