When does the special inspector need to contact the RDP?

The special inspector is required to contact the Registered Design Professional (RDP) when a non-conforming item is not being corrected adequately. This is essential because the RDP has a responsibility to ensure that the design meets the code and project specifications. When the special inspector identifies a non-conformance—such as a structural element that does not align with the approved plans or materials that do not meet specified standards—it's crucial to communicate this issue promptly to the RDP. This allows for the necessary expert guidance or immediate corrective actions to be taken.

Timely communication in this situation helps to maintain the integrity of the construction process and ensures that any issues are addressed quickly, ultimately protecting the safety and quality of the project. The RDP may need to review the situation, suggest alternatives, or approve changes to rectify the non-conformance effectively. This interaction is fundamental to uphold the collaboration and accountability among all parties involved in the construction project.
