Steps
Distinguish the two credential tracks: the International Masonry Institute (IMI) is the labor-management training arm affiliated with the International Union of Bricklayers and Allied Craftworkers (BAC), running apprenticeship and journey-level craft training for trowel-trade workers (masons, tuckpointers, plasterers, etc.)
Recognize BAC/IMI apprenticeship as a paid, on-the-job-plus-classroom training pathway for individual craftworkers, and check for a local BAC/IMI training center or apprenticeship fund when evaluating a crew's mason-level training credentials
Separately, recognize the Sealant, Waterproofing and Restoration Institute (SWR Institute, commonly SWRI) as an industry trade association that validates training programs and standards specifically in the sealant, waterproofing, and restoration construction sector, rather than a craft-apprenticeship body
When evaluating a contractor for restoration work involving both masonry and building-envelope sealant/waterproofing scope, check for BAC/IMI-trained craft labor for the masonry portion and SWRI-affiliated training/standards familiarity for the sealant/waterproofing portion, since these cover different skill domains
Verify current program and certification details directly on the respective organizations' websites (imiweb.org / bacweb.org for IMI/BAC; swrionline.org for SWR Institute) rather than assuming a single unified 'masonry restoration certification' exists across both
Use these credentials as one input to contractor qualification (alongside references, licensing, and insurance), not as a substitute for verifying the specific crew's experience on comparable historic/restoration projects
Known gotchas
IMI/BAC and SWR Institute are not the same organization and don't share a unified certification — don't present 'SWRI certified' and 'IMI/BAC trained' as interchangeable claims when qualifying a contractor
BAC/IMI apprenticeship applies to union-affiliated craftworkers; non-union restoration contractors may have equally competent crews trained through other pathways, so absence of a BAC/IMI credential is not by itself disqualifying
SWR Institute's role is largely industry standards/training validation for the sealant-waterproofing-restoration sector broadly, not a masonry-specific hands-on trade certification — confirm what a given credential actually attests to before relying on it
