Which procurement method is characterized by two phases and the owner's defined project requirements?

The procurement method characterized by two phases and the owner's defined project requirements is the traditional design-build method. In this approach, the project is divided into distinct phases: the design phase, during which the owner's requirements are elaborated, and the build phase, where the construction occurs based on that design.

In the traditional design-build process, the owner plays a significant role in defining the project requirements upfront, which informs the design and ultimately impacts the construction. This method emphasizes a single point of accountability, as the design and construction are contracted together, streamlining communication and collaboration between the stakeholders involved.

This procurement method allows for a more integrated approach, with the design team often collaborating closely with the construction team to ensure that the project meets the owner's expectations throughout its lifecycle. Moreover, by having the owner's requirements clearly outlined in advance, the risk of disputes over design compliance or project specifications tends to be lower compared to other methods, fostering a constructive relationship between the owner and the design-build team.
