The project submittal should include which of the following?

• A. Shop drawings
• B. Product data
• C. Calculations
• D. All of the above

Answer: (D)

The main idea here is that a project submittal for a special hazards system must be a complete package that shows how the system will be built, what equipment is being used, and how it will perform. Shop drawings translate the design into concrete installation details—layout, dimensions, routing, and how components will connect in the actual space. Product data provides the technical specifics of each item, such as performance characteristics, materials, and compliance information, so reviewers know exactly what is being installed. Calculations demonstrate performance and compliance, like hydraulic calculations, flow rates, and pressure requirements, proving the system will meet required standards.

Together, these elements let reviewers verify constructability, compatibility, and performance before fabrication or installation begins, reducing the need for backtracking or redesign. That’s why the submittal should include shop drawings, product data, and calculations—the complete package.
