Who does CCDC 14 primarily involve?

CCDC 14, which refers to the "Contract between Owner and Design-Builder," is specifically structured to facilitate the relationship between the owner and the design-builder in a design-build project delivery method. This type of contract is designed to streamline the project by integrating both the design and construction services within a single contract.

The owner is the party that seeks to create a facility or structure and engages the design-builder to handle both the design and construction aspects. This alignment helps in reducing overall project timelines and enhancing collaboration since the design-builder assumes responsibility for both the aesthetics and building performance from the start.

The other answer choices represent relationships that are not central to the CCDC 14 framework. While the construction manager, architect, contractor, subcontractor, and supplier each play significant roles in various project delivery methods, they do not directly pertain to the structure established by CCDC 14, which is specifically tailored for the owner-design-builder relationship.
