SITE SET-OUT POINT
Site is surveyed and set-out from this point - this helps the contractor have a continuous reference point for dimensions of the grid and to establish site boundaries.

Following demolition of existing house. All debris, building rubble, surface vegetation and top soil is removed from the site.
1.03
Sufficient soil support is necessary prior to trenching. Engineered fill is applied and compacted in layers as per structural engineer specifications.
1.05
Service pipes are placed into trench, back-filled and capped. They are wrapped in protective fabric to protect them from damage during the early stages of the build.

0.2mm Polyethylene is laid to seal 50mm level sand bed (pictured). This performs as a vapor barrier to reduce ground moisture reaching and compromising footings/slab.
1.02
Trenches are dug using an excavator which operates parallel to the trench. 2000 x 1000 x 500 (min) depth is dug for PF2 (pad footings) centered beneath columns.
1.04
Fourth and final layer of engineered fill is applied and compacted through proof rolling. This will expose soft spots (F6 structural specs) that require additional fill.
1.06
Contractors erect temporary form-work in accordance with AS3610. When inspection/ approval is made - then footings are poured to prevent ingress of loose sand.
1.09
Reinforcement mesh and bars, temporary formwork, and void formers are transported to/stored on site in preparation of their respective uses in next stages.
