SITE PREPARATION AND FOOTING

After obtaining a building permit and demolition permit, contractors establish location of existing services and terminate any active services before commencing works on demolition. Soil report analysis is conducted by geotechnical engineer as per AS1289:2014 to assess properties and to begin excavation. Site is measured out and any potential risks and issues are assessed.

GROUND FLOOR SLAB

Envirocrete recycled concrete placed as per AS2870:2011, slump test carried out to ensure structural integrity of concrete used. Isolated 110mm suspended slab used for cellar to provide extra isolation and extra insulation. 25mm SL82 fabric top cover and 10mm Abelflex expansion joint installed between vertical faces of concrete between main slab and suspended slab.

After foundation preparation, 50mm of sand is levelled and a 0.2mm polyethylene moisture barrier is placed to prevent moisture from seeping in from underneath the slab. This is then covered by a SL82 Top 40mm fabric cover with hydronic heating coils placed as per mechanical drawings, with a SL62 20mm fabric cover placed over hydronic coils. 110mm thick polystyrene waffle pods are placed as per structural drawings with ribs forming maximum 1200 centres, this minimises the use of concrete, however, in certain areas, mass concreting is used to provide increased structural support, specifically surrounding steel members. Steel reinforcement is used to provide tensile strength, with vertical members and plates placed to connect with vertical structures.
