Ideal Geotech has it’s feet firmly planted in the residential housing market from the start when a site is being developed and subdivided to individual house lots. Our timely testing and reporting structure assists developers with the information required for better decision making for your proposed subdivision. Our engineers also work with planners and surveyors who specialise in subdivision applications. The following are typical geotechnical/environmental tests and assessments commonly carried out for proposed subdivisions.
|PAVEMENT TESTING & DESIGN
Pavement design must be adequate to withstand the loads imposed for the purpose of the pavement use and or by council load requirements. We can provide pavement testing and design for residential & industrial subdivisions, roads, carparks and other pavement types.
We carry out detailed geotechnical field investigations and laboratory testing to provide a comprehensive report for cost effective pavement design of new pavements.
Level 1 and Level 2 testing & inspection In accordance with AS3798-2007 Guidelines on earthworks for commercial and residential developments.
Our team will assist you in all aspects of your Level 1 or Level 2 project. As an independent geotechnical testing authority we will reduce technical risks through sharing our experience and knowledge of local quarry products and materials. This will ensure your project conforms to the design and technical specifications.
Level 1 testing and inspection involves a full time representative from Ideal Geotech be present at all times during fill placement, subgrade preparation and any other earthwork operations such as:
On completion of earthworks Ideal Geotech will provide a detailed report outlining inspections, sampling and location of testing carried out.
|WASTE CLASSIFICATION & VENM/ENM TESTING
A validation report (if applicable) shall be submitted to Council or Certifying Authority. The validation report must include the following:
Disposal of Soil & Waste Classification
Before soil can be removed from the site soil has to be classified. Waste is classified under six classifications by the NSW Environment Protection Authority (EPA). The classification of waste into specific groups that pose similar risks to the environment and human health allows for appropriate management and disposal at licensed landfills.
Testing for VENM and ENM is required for any soil that you plan to remove off the site.
If the soil on the site is not classified as ENM or VENM, then it can not be reused in NSW.
Virgin Excavated Natural Material (VENM) EPA Fact Sheet
Virgin excavated natural material means natural material (such as clay, gravel, sand, soil or rock fines):
- that has been excavated or quarried from areas that are not contaminated with manufactured chemicals, or with process residues, as a result of industrial, commercial, mining or agricultural activities
- that does not contain sulfidic ores or soils, or any other waste,
Excavated Natural Material (ENM) EPA Fact Sheet
Excavated Natural Material (ENM) is naturally occurring rock and soil (including materials such as sandstone, shale, clay and soil) that has:
- Been excavated from the ground
- Contains at least 98 per cent (by weight) natural material
- Does not meet the definition of Virgin Excavated Natural Material (VENM).
ENM does not include material that has been processed or contains acid sulphate soils or potential acid sulphate soils.
|LOT CLASSIFICATION – FINAL
The lot classification for the subdivision is completed across the property with appropriate number of boreholes and soil samples taken to suit the requirement of the the property size. As well as classifying the soil conditions of the site and determining the amount of fill used, laboratory testing is done where appropriate.
