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?
