Mitigating Geotechnical Risks for Safer Developments
Assess and map potential geohazards, helping developers identify risks and create safer land use plans for construction projects.
Geological hazards such as unstable ground, soft soils and faulting leave identifiable traces on the landscape. Early identification of these hazards is critical to reducing risks and implementing effective solutions during the design and construction phases of any project.
KGA have strong expertise in landslide risk assessments whether carrying out initial hazard risk assessments shortly following the event, or full detailed investigations to determine mitigation or remediation options. KGA has actively been involved in Land Categorisation assessments for Auckland Council following the Auckland 2023 flood events.
Our office in Christchurch is highly experienced in liquefaction and lateral spreading assessments for existing and new developments.
Proactive Measures for Safer Site Development
Incorporating hazard mapping into the early stages of a project ensures risks are addressed effectively.
Practical solutions like ground stabilisation, drainage, and fault zone avoidance can help mitigate hazards identified during the investigation phase.
Methods of Hazard Identification
Techniques for Detecting Geological Risks
Combine the review of a number of data sources to develop a comprehensive understanding of the potential geo-hazards at a site.
Can assist with the identification of geomorphological features such as landslide scarps and fault lines from above and can provide a record of geomorphological changes in an area over a period of time.
A geomorphological assessment provides further identification of features on the ground which may not be apparent through observation of geological maps or aerial images.
Borehole drilling, testing, geophysical investigation, and laboratory testing are often integral components of hazard risk assessments.
Identifies the likely soil and rock types and known structural geological features (such as folds and faults) in an area, which can be used as part of the hazard assessment.
