TQ173 Multi Unit slab calculation v4.1 November 2022 EHC
Approved Ruling:
The NZGBC advises that the internal slab perimeter can be excluded as the slab appears to be joined, making it continuous even though there is a set down. The internal perimeters are not exposed to external conditions. In that case, option 1 would be appropriate for slab 4. However, if there was a gap between the slabs, that would make it independent of the other slab and exposed to external conditions. Then the internal perimeter would be included in the perimeter measurement.
