Who signs the special inspection agreement?

The special inspection agreement is a crucial document in the construction process that ensures accountability and defines the roles of those involved in special inspections. This agreement typically requires the participation and signatures of several key stakeholders to validate its authority and effectiveness.

The registered design professional and the special inspection agency must sign the agreement to establish a formal relationship and outline the responsibilities regarding the inspection process. This ensures that the design intended for the project is effectively monitored through proper inspections by qualified agencies.

Additionally, the building official is also involved in the signing process, as they play a critical role in enforcing building codes and regulations. Their signature indicates that the agreement complies with local codes and standards, thus providing an added layer of oversight.

Since all these parties—building official, contractor, registered design professional, and special inspection agency—play essential roles and are involved in the special inspection process, their signatures are necessary for a comprehensive and enforceable agreement. This collaborative approach helps ensure that all aspects of the project are properly inspected, thereby enhancing safety and adherence to regulations.

Therefore, the correct answer encompasses all parties involved, confirming that the involvement of each party contributes to the integrity and functionality of the special inspection agreement.
