Hi Phil, I think it would be great to get a group together to hopefully find some consensus on this! It would be very helpful to have people involved in benchmarking, that use BIM for material quantities, WB-LCA practitioners/tool providers, and/or those familiar with construction classification standards like Uniclass, OmniClass, MasterFormat, UniFormat, etc.
I’m doing some research on this topic now to assemble enough material/ideas to start this type of discussion. I think it’s really important to get this as right as possible from the outset to give it the best chance at industry uptake.
