The core of our service is geotechnical assessment and design for infrastructure projects, buildings, and land developments. Our specialists use a range of analytical techniques including numerical modelling to identify specific geotechnical design requirements. We provide geotechnical design services for foundations; soil and rock slopes; retaining structures; ground improvement; dams and reservoirs; marine and near-shore structures; deep basements; temporary works; quarries, landfills, mines, and tailings dams. We also offer value engineering services, providing alternative design solutions for more cost-effective construction.
Our engineering geology group specializes in inspection, hazard and risk assessment, and design of remedial works for steep soil and rock slopes, as well as the management of slopes, tips, and lagoons for quarrying. Our qualified rope-access specialists can physically assess, analyse, and monitor steep slopes with challenging access points. Coffey has sector-leading experience and expertise in analysing and presenting data using advanced commercial and customized software. We have the thorough technical understanding and high-level IT capabilities required to collate, manage, and present surface mapping and 2D and 3D survey data Our engineers and geologists combine these attributes to produce accurate 3D ground models depicting surface terrain, sub-surface stratigraphy, and geotechnical features
We combine our geotechnical and geoenvironmental skills to complete contaminated land feasibility studies, ground and groundwater investigations, risk assessment, engineering evaluation, detailed design of remedial works, and construction supervision. Our geoenvironmental engineering services can be applied to a broad range of scenarios including pre-acquisition assessments, standard site assessment, brownfield redevelopment, remediation assessment, and validation. We advise clients on contaminated land issues and provide expertise in technical, sustainability, and financial aspects of development and operation of modern waste disposal facilities. Our team has specialized expertise in issues related to landfills and industrial lagoons with complex geotechnics to accommodate hazardous or special wastes.
We have a number of high profile engineers that are frequently called upon to provide expert opinion. Our expert services include technical investigations and reporting, forensic engineering, advice on claims and contract matters, and assistance with adjudication. We also provide expert advice and expert witness services at public enquiries, arbitration, and provide evidence in High Court proceedings.
