Core offering

Coffey Geotechnics delivers ground engineering design and advisory services across geotechnical engineering, engineering geology, hydrogeology, geo-environmental, geoinformatics and mining engineering. The consultancy supports clients from feasibility and ground investigation through to design, construction support and expert witness testimony on infrastructure, property, energy, water, mining and public-sector projects in the UK and internationally.

Product overview

Coffey Geotechnics delivers a unified portfolio of ground engineering consultancy services rather than a software product with discrete modules, organised around six core specialist areas — Geotechnical Engineering, Engineering Geology, Geoenvironmental Engineering, Hydrogeology, Geoinformatics, and Expert Witness Services — which are applied across industry sectors including Energy, Water, Highways, Rail, Groundwater Control, Property, Sustainability, Temporary Works, Asset Management, Quarrying and Minerals, and Waste Management. Geoinformatics supports the other services by providing 3D modelling, numerical analysis, and BIM Level 2 output, while Expert Witness Services draws on the technical expertise of the engineering teams to provide forensic and litigation support. The offering is delivered through offices in Harrogate, Manchester, and Reading, with access to a global Tetra Tech network of more than a thousand ground engineering specialists.

Broad incumbents

• AtkinsRéalis: Global multidisciplinary engineering consultancy (formerly Atkins/SNC-Lavalin) that delivers geotechnical and ground engineering as part of much larger transport, infrastructure and nuclear mandates — directly competing with Coffey for UK rail and highways frameworks while also bundling broader design services.
• Arup: Global engineering consultancy with deep geotechnical and tunneling capability, often engaged on landmark UK and international infrastructure where Coffey also operates (Crossrail, HS2, major station redevelopments).
• Mott MacDonald: Large UK-headquartered multidisciplinary consultancy with a strong ground engineering practice, routinely competing with Coffey for water, transport and energy mandates and offering full-project bundling.
• WSP: Global engineering professional services firm with a large UK ground engineering team covering rail, highways, property and water — a direct competitor for many of the same Network Rail, National Highways and HS2 commissions Coffey targets.
• Jacobs: Global professional services firm delivering geotechnical and tunnel engineering on UK and international transport, water and environmental programmes — competing for the same tier-one contractor and public-sector commissions.
• Ramboll: Engineering, design and consultancy group with a strong UK geotechnical offering and a listed Coffey collaborator; competes for similar transport, property and energy mandates and can deliver multidisciplinary packages.
• AECOM: Global infrastructure consultancy delivering ground engineering within large transport, environment and water programmes in the UK — overlapping with Coffey on rail, highways, dams and coastal defence work.

Direct peers

• Structural Soils: UK-based geotechnical and geoenvironmental site investigation contractor, part of the ESG group — competing directly with Coffey in ground investigation, geotechnical design and laboratory testing for UK infrastructure clients.
• Fugro: Dutch-headquartered global geoscience and geotechnical specialist providing site investigation, geotechnical engineering and monitoring — a direct specialist peer to Coffey in ground investigation, foundation design and offshore/site characterisation.
• Soil Mechanics (part of ESG Group): UK geotechnical contractor and consultancy (now under the Environmental Scientifics Group) delivering ground investigation, geotechnical design and laboratory testing — a directly comparable specialist geotechnical peer for Coffey's UK infrastructure work.
