In which delivery method is owner involvement minimized after construction is initiated?

The design-bid-build delivery method is characterized by a sequential process where the owner is primarily involved during the initial phases of the project. In this method, the owner engages with the designer to outline the project requirements and subsequently bids the construction phase to a contractor. Once construction is initiated, the contractor independently executes the construction work based on the completed design documents with minimal ongoing involvement from the owner.

In this structure, after the selection of the contractor, the owner's role significantly diminishes. They typically do not play an active role in day-to-day construction decisions or management. The contractor is responsible for overseeing the project's execution, managing the construction team, and solving any issues that may arise on-site, allowing the owner to focus on administrative aspects rather than the technical details of construction.

The other delivery methods involve higher levels of owner participation or collaboration during construction. For example, in design-build and integrated project delivery methods, the owner remains more involved throughout the project, often collaborating closely with the design and construction teams. In construction manager at risk, while the owner retains some involvement, the construction manager also plays a critical role in decision-making and risk management.
