IBC special inspections for CJP and Multi-pass field welds?
(OP)
Per Table 1704.2 in IBC 1704.2, any field welds that are complete joint penetration, multi-pass, or fillet welds greater than 5/16", require continuous inspection. I believe this means that a certified weld inspector has to be present during the entire installation of these welds.
Has this been occurring on your projects? Has this requirement caused you work to harder to avoid these type of welds?

The code just says that the Special Inspector shall be qualified by the EOR. I might interpret it as being one of our regular guys. Some other engineer might require a Certified Weld Inspector.

ICC-Structural Welding Special Inspector does not require one to be a CWI, and this cert is open to anyone to walk in and test who has $200 to burn.... CWI has experience requirements for the application, but i doubt AWS fact-checks. Either is usually written into specs.
In my region, North Carolina, this is regularly scoped and done in inspection/testing props. Owners do have choice in who they hire. I get to see competition proposals from time to time and was not surprised to see the our market leader had 1/10th the steel inspection hours of the pack. You just can't sign off on each floor of a multi-story steel building full of moment welds and in a total of 20 hrs, even by skipping ndt and continuous observations.

The 2012 IBC requires special inspections in accordance with AISC 360-10 Specification for Structural Steel Buildings ( a free download at http://www.aisc.org/content.aspx?id=2884#spec). Chapter N of this specification requires inspection (quality assurance) of all welds, but it uses "perform" and "observe" rather than "periodic" and "continuous". It also requires that all provisions of AWS D1.1 be met. The commentary to chapter N provides some insight to the meaning of "perform" and "observe". Bottom line: welding inspection is required but it may not need to be continuous (read the commentary to chapter N).
