What is the most appropriate way to require an accredited/certified metal building manufacturer in project specifications?
The AISC-MB certification has been phased out and is transitioning to IAS AC472 (International Accreditation Service). There appear to be only 6 metal building manufacturers with IAS accreditation so far. If I were to require IAS in my spec, many MBM’s would be unnecessarily disqualified. Many more MBM’s have AISC-MB certification, but is this program dead? Is specifying AISC-MB still applicable?
Should I specify IAS, MB, both, or neither?
Thanks,
