Which phase in design sequencing includes finalizing working drawings and contract documents?

The phase in design sequencing that includes finalizing working drawings and contract documents is known as the Construction Document (CD) Phase. During this phase, detailed drawings and specifications are created to provide all the necessary information for construction. These documents serve as the primary reference for contractors to prepare their bids and carry out the construction of the project. The drawings detail dimensions, materials, and construction techniques, while contract documents outline the contractual obligations and terms of the project.

In contrast, during the Design Development (DD) Phase, the project is still evolving; the overall design is refined, but final construction documents have not yet been completed. The Bidding/Negotiation Phase occurs after the CD Phase, where contractors submit bids and the owner selects a contractor based on these proposals. The Construction Phase follows after the bidding process when the actual construction takes place based on the finalized documents. Therefore, the CD Phase is distinct in its focus on producing the definitive documents needed for the successful execution of a construction project.
