Which method involves early involvement of specialty subcontractors to inform design decisions?

• A. Integrated Project Delivery
• B. Studio Organization
• C. Design-Assist Contracting
• D. Single Purpose Entity

Answer: (C)

Early involvement of specialty subcontractors to inform design decisions is achieved through design-Assist contracting. In this approach, key trade partners with specialized knowledge are brought into the design process early, providing input on constructability, sequencing, fabrication methods, and procurement constraints. Their practical perspective helps shape design choices—such as equipment types, system layouts, and installation details—so the design is more buildable, cost-aware, and less prone to mid‑project changes. The architect or engineer maintains overall design responsibility, while the contractor and selected subs contribute expert recommendations under defined collaboration terms. This clarity of roles and early trade input makes design-Assist especially effective for complex or high‑cost systems where early visibility into fabrication and installation can significantly improve outcomes.
