Dear Sir,
While I am sure that I do not know all of the difficulties of your situation, this problem, and the other problems that you have posted have led me to believe that this project is doomed for multiple catastrophic failures which may indeed lead to loss of people's lives and failure of the entire system.
The Contractor seems to not care at all about the future integrity of this project.
The owner or owner's representative's also seem to only care about getting the project online, regardless of the risks.
I wonder who will be held responsible when these systems begin to fail?
As the Consultant, have you been signing your name for approval of these systems?
If so, it seems to me that you are being set up as a "scapegoat", or someone who will take the blame.
If it were me, I would copy documents that show that these systems have not been constructed in compliance with the applicable Codes, quit the job under protest of these events and forward copies of the documents to whatever authority there may be that can properly investigate this situation.
Again, I don't pretend to know all of the details of your situation. I am only able to base my opinion on the numerous posts that you have made on this forum.
I wish you luck, sir, in whatever you decide to do, as I am truly concerned about your safety and the safety of the people who will be operating these systems in the future.

NASA learned a gruesome lesson in one of it's space capsules by using oxygen as the atmosphere for the astronauts. It sounds as though this facility could end up with atmospheres of oxygen in various parts of the facility with catastrophic results. I would concur with the other posters that are warning you about the situation that you are describing. Good luck in rectifying this obviously dangerous situation. aevald
I never signed any approval document about particular work,but I tried to stop this method and proved that all defected welds must be repaired according to standard with proper WPS.But I wanted to get your approval and tell them that they are not doing the proper method. Also please reply to my last question with this topic:(Weld imperfection )
