Authorized Inspector (AI) Inspections
Authorized Inspector (AI) Inspections
(OP)
I work as a QC Manager for a company that manufactures jacketed pressure vessels. When I schedule a inspection with my AI to review a new job, he insists on reviewing my vessel calculations page by page, and requesting changes when he finds a mistake. I have no problem providing him with the calculations to ensure they have been done for the job, but does he have the responsibility of finding mistakes in them and requesting them to be fixed? I remembering somewhere it coming to light that this is not one of his responsibilities, and that he is to ensure the job is built per drawings that he is provided and built per ASME?

It is the AI's responsibility to validate your calculations and he has the right to request (or demand) that incorrect calculations be fixed. If your Code of Construction is ASME Section VIII, Division 1, please refer to U-2(e)...
"It is the duty of the Inspector to make all of the inspections specified by the rules of this Division, and of monitoring the quality control and the examinations made by the Manufacturer. He shall make such other inspections as in his judgment are necessary to permit him to certify that the vessel has been designed and constructed in accordance with the requirements. The Inspector has the duty of verifying that the applicable calculations have been made and are on file at Manufacturer’s plant at the time the Data Report is signed. Any questions concerning the calculations raised by the Inspector must be resolved."
Calculations are required to verify that minimum requirements of the Code have been complied with. The only way for the AI to confirm that your calcs are correct is to review them. Nobody in his right mind would certify documents or calculations without thoroughly reviewing them. It is unethical to do that!
I am not an AI, but sometimes I am assigned to review vessel drawings and calculations. I don't look for mistakes. I ensure that drawings and calculations are correct and meet Client or Code requirements.
