Geotechnical services including investigation, mapping, design, analysis, construction, forensics and dam safety assessment for dams and civil structures.
Embankment dams including detention dams, tailing dams, canals and stopbanks
Geological mapping
Compressible, liquefiable and unstable foundation assessment, design and mitigation
Numerical modelling and ground deformation analysis
Piping and internal erosion
Risk assessments
Intensive investigation programme and landslide stabilisation works undertaken.
The stabilisation measures implemented for landslides could include:
Tunnel layouts developed with the dual objectives of providing definitive information on the landslides and stabilisation by drainage.
Drainage tunnels below lake level.
Buttressing for smaller slides.
Embankment/slope stability analysis
Seepage analysis
Foundation analysis
Specialist erosion, shear strength and cyclic testing interpretation
Geological and geotechnical desk top studies
Geotechnical design and remediation
Geo-structural modelling, analysis and design
Ground improvement and embankment stabilisation
Earthworks construction monitoring and inspection
Earthquake geotechnics: Site specific seismic response
A peer review is a professional opinion based on sound engineering analysis and assumptions, good practice, appropriate regulations and unbiased judgement.
Peer reviews can be limited to certain key parts of the engineering work.
A peer review is intended to reveal issues rather than necessarily resolve them. But it can be a key resource for subsequent work towards resolving any issues that are identified.
