• C. The name, address, phone number, and certificate of registration number of the registered firm
• D. The license number of the RME, the date of installation, alteration, or addition, and the name, address, phone number, and certificate of registration number of the registered firm

Answer: (D)

Stamps on sprinkler plans exist to ensure accountability and compliance by tying the work to a licensed professional and a registered firm. The license number of the person stamping the plan shows who is legally responsible for the design and supervision, making it easy for inspectors to verify qualifications. The date of installation, alteration, or addition links the plans to a specific project stage, helping track when the work was performed or approved and ensuring the document reflects the current scope. The name, address, phone number, and certificate of registration number of the registered firm identify the company responsible for the work and provide a contact and verification trail for regulatory review. Together, these elements establish who is responsible, when the work occurred, and who to contact for compliance questions, which is why all three must appear on the stamped plans.
