Which statement is true about the requirement to display the registration certificate number on documents?

• A. Only installation drawings
• B. Every bid, proposal, offer, and drawing
• C. Only bids
• D. None

Answer: (B)

The main idea is that the registration certificate number must be shown on all documents connected with a project, not just a subset. Requiring the number on every bid, proposal, offer, and drawing ensures that the person or company submitting the plan or cost estimate, as well as the drawings themselves, can be readily verified as properly registered. This creates a clear chain of accountability and helps plan reviewers and authorities confirm compliance before work proceeds. Limiting the display to only installation drawings or only bids would leave gaps where verification isn’t visible, so the rule is to include the registration number on every bid, proposal, offer, and drawing.
