I'm in the process of bidding 2 structural steel up fit jobs. The structural prints details call for AWS D1.1 certification, one to be supplied to the Architect. They offer no WPS requirements or test shop. I have a shoe box full of certs, mostly 6-G, but all were specific WPS for said jobs and employers. What do I need to satisfy said requirements? Do I have to set up and pay for an independent test with a CWI to qualify? Who provides the WPS?
