In the design bid build paradigm, who holds responsibility for the success of the design details?

In the design-bid-build paradigm, the owner holds responsibility for the success of the design details because they are typically the one who initiates the project and provides the overall vision and requirements. In this traditional delivery method, the owner contracts separately with the design team and the contractor, which places the onus on them to ensure that the design meets their expectations.

The design team is responsible for creating the details and specifications, but ultimately it is the owner's role to review and approve these designs before they are executed in the construction phase. This means that the owner's input and decisions directly influence how successful the design details will be in achieving the desired outcomes for the project.

In contrast, while the contractor and subcontractors play important roles in construction and can offer input on practicality and cost-effectiveness, they do not hold the final responsibility for the design's success; their role is more about implementation and handling any issues that arise during construction.
