If a discrepancy is found in the welding from the approved construction documents, who should be informed immediately?

Informing the contractor immediately if a discrepancy is found in the welding from the approved construction documents is crucial because the contractor is responsible for overseeing the construction site and ensuring that the work is carried out according to the specified plans and codes. The contractor can assess the situation and determine the necessary corrective actions, which may include stopping work, making repairs, or coordinating with engineers or architects to evaluate the impact of the discrepancy.

This approach ensures that any issues are handled swiftly and properly, maintaining safety standards and compliance with regulations. Other parties, such as the construction crew, client, or building inspector, may also need to be informed eventually, but the contractor is typically the first point of contact in such scenarios for immediate resolution.
