To whom shall the contractor provide a copy of the examination results upon request?

The contractor is required to provide a copy of the examination results to the administrative authority upon request. This is essential because the administrative authority is responsible for enforcing compliance with safety standards and regulations within the jurisdiction. Ensuring that all examination results are submitted allows the authority to verify that safety norms are met and that the contractor's work is up to code.

The role of the administrative authority includes monitoring contractors and ensuring public safety. By receiving these examination results, they can maintain oversight and ensure that proper practices are being followed during high-pressure piping installations. This requirement reflects the accountability measures in place to uphold industry standards and regulations to protect workers and the public.

The other options revolve around various stakeholders involved in construction projects, but their roles do not typically necessitate the direct receipt of examination results as part of regulatory oversight. The project manager, state inspector, and property owner may have interests in the project, but the administrative authority serves a specific regulatory purpose that makes it crucial for them to access these results when needed.
