Cross-laminated timber, or CLT, is the rising star of the mass timber structural family, yet the BIM user is often faced with a lack of detailing and dimensional coordination information for a young industry segment that is not yet fully standardized across the different producers. We started this catalog library with mass timber floor assemblies (horizontal system families used like a slab-on-beam structure), and we offered user-defined criteria to filter the options down with sustainable sourcing, certifications, and fire resistance. More options and manufacturers are being added continuously to this growing segment so check back in often and contact us with questions.
