Which document tends to be project-specific and shows fabrication details used by the fabricator?

• A. Product data.
• B. Shop drawings.
• C. Payment request.
• D. Change directive.

Answer: (B)

Shop drawings are the documents created by the fabricator or contractor that show exactly how components will be fabricated and installed on this project. They translate the design into specific construction details—dimensions, tolerances, material grades, finishes, fasteners, connections, and coordination with other parts of the work. Because they are based on the actual project conditions and contract documents, they are inherently project-specific and used by the fabricator to guide fabrication and on-site assembly.

Product data, on the other hand, provide general manufacturer information about a product’s performance and installation guidelines, not the precise, project-centered fabrication details. A payment request is an invoice, and a change directive is an instruction to modify work; neither conveys the fabrication specifics that shop drawings contain.
