TallyCAT is designed to bridge the gap between Revit models and EC3, allowing model information to be transmitted to the EC3/TallyCAT system. It’s similar to how Tally simplified LCA take offs in Revit, but with a larger database of materials, although it’s only carbon focused. EC3 can still be used without any BIM model because you can manually enter in material quantities. it’s a bit of a pain to do it this way, and it’s more likely set up for contractors than architects, but the functionality exits.
