What is the project delivery method where the owner collaborates directly with the architect and engineers at the start?

The project delivery method where the owner collaborates directly with the architect and engineers at the start is Integrated Project Delivery. This approach is characterized by a high level of collaboration among all project stakeholders. In Integrated Project Delivery, the owner, architect, engineers, and often the contractors work together from the very beginning of the project. This collaboration fosters open communication, shared goals, and a collective responsibility for the project's success, which can lead to increased efficiency and reduced risks.

In this method, early involvement of key participants is crucial; it allows for better alignment of the project team’s objectives and a more integrated approach to design and construction. By involving multiple parties early, issues can be identified and addressed sooner, which helps streamline the overall process and enhances project outcomes.

This method differs significantly from others, such as Design-Bid-Build, which typically involves a sequential process where the design is completed before bidding, and then construction begins separately. There is also Design-Build, where design and construction services are contracted by a single entity, but it doesn't emphasize the collaborative initial phase as strongly as Integrated Project Delivery does. "Construction Drawings" refers to the detailed drawings necessary for construction rather than a delivery method.
