What is the difference between a shop drawing and a product data submittal?

• A. They are the same.
• B. Shop drawings are manufacturer specs; product data show fabrication details.
• C. Product data include installation details; shop drawings include installation instructions.
• D. Shop drawings illustrate fabrication/installation details; product data provide manufacturer specifications and installation recommendations.

Answer: (D)

Shop drawings are the contractor or fabricator’s detailed drawings that show exactly how a component will be fabricated and installed on site, including specific dimensions, tolerances, connections, anchors, and sequencing for installation. Product data come from the manufacturer and describe the product’s specifications, performance characteristics, materials, and installation recommendations or instructions—that is, what the product is and how it should be used, without detailing how that particular component will be fabricated on the project. The distinction matters because shop drawings translate the design into actionable, site-specific fabrication and installation plans, while product data confirm the product itself meets contract requirements and provides the proper guidance for installing it.
