Find a Geotechnical Engineer
Where the result shows a landslip area, a steep block or fill, Council will want a geotechnical report before it consents. The geotech investigates the ground, classifies the site and tells the structural engineer what the footings have to do.
Type your suburb or your address.
What they do
A site investigation (boreholes or test pits), a site classification under AS 2870 for the slab and footings, a slope stability assessment where the LEP landslip map or the DCP requires one, and recommendations for excavation, retaining walls and drainage. On the coast and the escarpment this is routine; on flat clay it is a short report.
When you need one
When the constraint chips on your result show landslip, when the block slopes more than a few metres across the footprint, when you plan to cut in a garage or basement, and on any Pattern Book job where the cut-and-fill limits are close.
How to choose
Ask for a fixed fee for the investigation and the report together and for their experience with your council's geotechnical policy. A chartered engineer (CPEng) with local jobs is what Council expects.
