Which project delivery method involves hiring one team for both design and construction?

The project delivery method that involves hiring one team for both design and construction is the Design-Build approach. This method integrates both the design and construction phases into a single contract, which allows for a more streamlined process. By having a single team responsible for both aspects, communication and collaboration are significantly improved, reducing the risk of misalignment between the design intent and the construction processes.

In a Design-Build scenario, the design and construction teams work closely together from the project's inception, promoting innovative solutions and efficiencies that can lead to time and cost savings. This integrated approach also minimizes the potential for disputes since the same entity is responsible for delivering the final product, thus providing clarity in accountability and reducing the project delivery timeline.

In contrast, the other methods, such as CM at Risk, Design-Bid Build, and Multiple Prime, involve distinct phases or separate contracts that may complicate coordination between design and construction, potentially leading to delays and increased costs. Each of these methods has its own characteristics and risks associated with project execution, making Design-Build a uniquely unified option.
