Forum Backlink List for BIM

I need a researched list of forums where a Building Information Modeling (BIM) services company can build quality SEO backlinks. The list has to be relevant to BIM, AEC, construction technology, or engineering discussions and contain fresh, active communities (no abandoned boards). For each forum, include: • URL and forum name • Domain Authority / DR or similar metric • Monthly estimated traffic or activity indicator (posts/week) • Link type allowed (signature, profile, in-post) and any posting restrictions • Quick note on how to register and typical moderation strictness Aim for at least 100 high-quality entries; more is welcome if they genuinely fit the brief. A simple spreadsheet or shared sheet is fine for delivery.
