In practice, what is the difference between a submittal and a shop drawing?

• A. Submittals are product data for approval; shop drawings show project-specific fabrication details.
• B. Submittals show project-specific fabrication details; shop drawings are product data.
• C. Submittals are only for finished materials; shop drawings are optional.
• D. Submittals are legal documents; shop drawings are invoices.

Answer: (A)

On a construction project, there are two distinct types of documents used for approval and coordination. Submittals present product data, literature, and samples from manufacturers that show the proposed materials and finishes will meet the contract specs and be suitable for application. They describe what will be used and how it should perform, and they are reviewed by the design team for compatibility with the project requirements.

Shop drawings, on the other hand, are the contractor’s or fabricator’s detailed drawings that show exactly how components will be manufactured and installed in the field. They translate the design intent into concrete, project-specific details—dimensions, tolerances, fabrication methods, connections, sequencing, and how the items will fit with existing work.

In painting and decorating work, a submittal would include product data sheets, color samples, VOC information, application guidelines, and warranties from the finish manufacturer. A shop drawing would show, for example, precise field installation details, substrate preparation steps tied to actual site conditions, masking and access plans, and how coatings or decorative elements will be applied and installed in place.

So the best answer is that submittals are product data for approval, while shop drawings show project-specific fabrication and installation details. The other descriptions mix up the roles—for instance, treating submittals as finished materials or shop drawings as invoices.
