The site should be cut and filled, or terraced, with engineered fill to receive a slab-on-the-ground foundation or a strip footing. The fill should continue past the edge of the foundation wall or edge beam by at least 1000 mm and have a batter of not more than one horizontal unit to one vertical unit. The fill should then be retained or battered beyond this point by a slope not steeper than two horizontal units to one vertical unit. The interior of the slab as well as the edge beam or strip footing will be set on natural soil or engineered soil.
Or a deepened edge beam or a masonry foundation wall supported on a strip footing set below the natural ground level shall be provided on the interior of the structure to retained controlled or engineered fill. Deepened edge beams and steps in the floor at any change in level of slab-on-the-ground may be accommodated.
