What must be affixed by the licensed RME type G, D, or U upon completion of the installation?

• A. A certificate of occupancy
• B. A project completion sticker
• C. A contractor's material and test certificate for aboveground or underground piping
• D. A performance bond

Answer: (C)

The key idea is that the licensed RME must provide formal documentation that the piping part of the fire sprinkler system was installed with approved materials and successfully tested. This contractor’s material and test certificate for aboveground or underground piping confirms that the pipes, fittings, and supports meet the approved plans and code requirements, and that the system has been properly hydrostatically tested to the specified pressure. It creates an official record for the Authority Having Jurisdiction and the building owner that the piping portion is ready for service. Other options don’t fit because a certificate of occupancy relates to building occupancy after all inspections, a project completion sticker isn’t a standard certification, and a performance bond is a financial guarantee, not a certification of installed and tested materials.
