GEOTECHNICAL & ENVIRONMENTAL SOLUTIONS
Residential
Before a proposed development or civil works proceeds, stabilisation works may be required to assess the risk associated with a potential failure or landslide. We also provide practical advice to manage an immediate risk and to reduce the consequence of any potential instability and regularly give advice on preferred design and construction practices for the development of sloping land. Alliance has significant experience working in the Northern Beaches Area and meeting council requirements.
Our landslide stability assessments are based on experience with geology and applying the current “Practice Note guidelines for Landslide Stabilisation Works” prepared by the Australian Geomechanics Society (AGS 2007). We have adopted the risk acceptance criteria set out in AGS 2007 to determine whether the risks to property or life associated with a given slope are ‘acceptable’, ‘tolerable’ or ‘unacceptable’.
TfNSW / RMS
We have substantial experience and RMS accreditation in undertaking slope stability assessments for civil, residential and commercial developments and are well versed with the common methods of risk management typically used by the RMS to control specific geotechnical issues in road cutting and embankment areas.
Effective risk management without significant costs
We have carried out stability assessments of a large number of slopes to classify the Assessed Risk Level (ARL 1 to ARL 5) in accordance with the RMS Guide to Slope Risk Analysis Version 4. This allows the RMS to prioritise any required remediation and create an inventory for further investigation, stabilisation works, monitoring, or asset maintenance.
