Which method incorporates both design and construction management under a single contract?

The design/build method is an integrated project delivery system that combines the design and construction phases under a single contract. In this approach, the design and construction responsibilities are handled by one entity, which can lead to better project coordination and potentially more efficient project delivery. Because both design and construction are managed simultaneously, there is typically a reduction in overall project time and streamlined communication, which can enhance collaboration and problem-solving during the project development.

This method contrasts with other approaches like design/bid/build, where the design and construction phases are separate and typically involve different contracts, leading to possible delays or miscommunication between the design and contractor teams. The construction manager and general contractor approaches involve different management structures but do not merge the design and construction processes in the same way that design/build does. Therefore, the design/build method stands out as the choice that effectively integrates both aspects efficiently and consistently.
