Which listing correctly names the participants in a panel layout discussion?

• A. Architect, engineer, and contractor
• B. Engineer, architect, and contractor
• C. Engineer and architect only
• D. Architect, contractor, and owner

Answer: (B)

In a panel layout discussion for tilt-up construction, the core participants are the engineer, the architect, and the contractor. The engineer shapes the structural feasibility, determining panel sizes, joint details, and reinforcements to ensure safety and performance. The architect then translates that structural framework into design intent, aesthetics, and coordination with spaces and openings, ensuring the panels meet the intended appearance and functional requirements. The contractor brings it all into the realm of buildability, planning sequencing, formwork, and on-site execution to keep the project practical and constructible. This ordering reflects the flow from technical feasibility to design integration to constructability, which is why the listing with engineer, architect, and contractor is the best fit. The other options omit a key participant or misrepresent the typical collaboration needed for panel layouts.
