Who does the contractor submit the QC plan to?

The contractor submits the Quality Control (QC) plan to the Engineer. This is a vital step in the construction project because the Engineer plays a crucial role in overseeing the project’s compliance with the contract specifications, ensuring quality standards are met, and reviewing the QC plan as part of the project's quality management process.

The QC plan outlines how the contractor intends to meet the quality standards required by the contract and specifies the methods and procedures for monitoring, inspecting, and testing materials and workmanship. Submitting this plan to the Engineer allows for thorough evaluation and approval before implementation, ensuring that all quality assurance measures align with the project requirements.

The other options involve stakeholders in the project but do not align with the specific protocol for submitting the QC plan. The Project Owner, State Authorities, and Quality Assurance Team may have roles in the oversight and evaluation of the project, but the direct submission of the QC plan is primarily addressed to the Engineer.
