Why is a Palace Pod ribbed raft waffle slab faster to construct?

Construction of the Palace Pod ribbed raft waffle slab takes place on a cleared level surface.

Traditional labour intensive trenching in preparing 'in-ground' perimeter foundation walls and ground beams, and multiple concrete pours are replaced with 'on ground' construction requiring no trenching*, minimal generation of spoil, and a single concrete pour with no backfilling after boxing is removed. (*Some digging of seismic piles may be specified by the engineer to anchor the raft slab.)

This speeds up construction Palace Pod ribbed raft waffle slab's irrespective of  the Wellington regions fickle weather.
