What characterizes a "Design-Assist" approach in design-build?

The "Design-Assist" approach is characterized by an arrangement where subcontractors are actively involved in the design development process. This means that rather than just executing the construction plans, subcontractors provide input on various aspects of the design, which allows for enhanced collaboration and problem-solving between design and construction teams. This collaborative effort typically leads to improved efficiency, cost-effectiveness, and innovation in the project, as subcontractors can offer practical insights based on their specialized knowledge and experience.

In this context, while stakeholders may engage in reviews and provide feedback, the core of the "Design-Assist" approach centers on the collaborative nature of the design development involving subcontractors. The remaining options do not aptly describe the essence of "Design-Assist." Designers making all decisions in isolation ignores the collaborative nature of the approach, and a focus solely on construction tactics would overlook the essential involvement of design considerations. Independent reviews of designs by stakeholders, while helpful in many contexts, do not characterize the "Design-Assist" model, which emphasizes the integration of construction expertise within the design phase itself.
