Question(s) and Reply(ies): Question: In a contract involving piping construction work, our company subcontracted the piping prefabrication work to a subcontractor. This subcontractor is managed by our company but has a different name. The subcontractor proceeded to qualify welding procedures which were conducted in the presence and with the approval of our company's welding engineer who monitored the welding of the test coupons and signed approval on the PQRs. The Quality Control System of the subcontractor and our company fully describe the operational control of procedure qualifications. Was our client right in rejecting the use by our company of the subcontractor qualified welding procedures for the erection work of the prefabricated piping?
