Hi guys,

Although this shouldn’t make a lot of difference to the LCA results, I think this assumption doesn´t meet the credit requirements as creating the voids and changing NLA could be considered changes in building scale and function. I´d recommend the client liaising about this with GBCA via a credit interpretation request (CIR).

In case there’s a regulation for the floor to be built to get occupancy permit and then demolished to create the void during fit-out design, I think both base and proposed designs should use the same assumption, and same NLA.

Cheers, Henrique
