- Setup Site facilities
Contractors have to provide welfare facilities including Site toilets, access to water and allocated rest area as well as a site office, site materials storage, access routes, deliveries area, waste management, appropriate signage and fencing as needed
- Clearing the site
Clear vegetation and organic matter from the area of the building, clear approved trees to be removed, tree roots and stumps from 2 metres around the extent of the building. Retain topsoil for later use. Protect existing trees by fencing them off to prevent filling or excavation of the root system.
2. Sub Floor Structure
- Foundations
The footing designs are to comply with the Australian Standard AS2870 and to be certified by a structural engineer.
- Excavation and Filling
Excavate trenches for footings to an even-bearing capacity.
- Site Drainage
Provide subsoil drains to the higher side of excavation in sloping site excavtions. Build drains with falls to storm-water lines to a min of 1:100 fall.
-General
- Order Steel Reinforcements, waterproof membrane, reinforcement supports, sand and fill for appropriate footing design.
- Construct Steel Reinforcement 'cages' on site and place into footings
- Fill with Concrete
