Geotechnical Engineering

Building Solid Ground for Every Stage of Your Project

Geotechnical Engineering

Built on solid ground

At Arthian, our geotechnical engineering services provide the insight and technical certainty required to deliver safe, efficient, and cost-effective development across the built environment. From the earliest stages of site planning to ongoing construction support, our team plays a critical role in helping clients make informed design and construction decisions β€” ensuring the safety, stability and longevity of developments.
 

We offer comprehensive geotechnical design services, including:


     

  • Geotechnical Investigation, including desk studies, geological considerations, GI design, procurement, site supervision, laboratory testing specifications and factual reporting.
  • Interpretation of geotechnical investigation data, including the preparation of Eurocode 7-compliant GIRs (Geotechnical Investigation Reports) and GDRs (Geotechnical Design Reports).
  • Bearing capacity, stress, and settlement calculations for structural and foundation design.
  • Ground improvement design
  • Shallow and deep foundation solutions, including ground bearing pads, raft slabs, piles and pile groups.
  • Retaining walls, slope stability assessments and embankment design.

Our Geotechnical Engineering Capabilities

Whether you’re working in construction, renewables, infrastructure, or industrial development, our geotechnical engineers help you understand your ground conditions β€” and how to build successfully upon them.

Temporary Works and Site Support

Additional Services

Temporary Works and Site Support

Our expertise extends to geotechnical input for temporary works and construction support:

     

  • Crane pad assessments – including ground bearing capacity checks and outrigger spreader mat selection based on site-specific loading conditions.
  • Temporary works design – including open-cut and shored excavations, cantilever sheet pile walls, geogrid-reinforced haul roads, and working platforms.
  • Category 3 independent checks – of designs undertaken by others to ensure compliance and safety.
  • Construction phase support – such as formation level inspections before placing ground-bearing foundations.

Specialist Geotechnical Services

We support a wide range of infrastructure and development challenges with bespoke technical solutions:

     

  • Tank settlement analysis – modelling long-term settlement performance based on geotechnical parameters.
  • Riverbank erosion and remediation – evaluating and mitigating erosion risks adjacent to infrastructure or loading areas.

Additional Services

We also provide targeted studies and assessments for site-specific risk and cost control:

     

  • Coal Mining Risk Assessments (CMRA) – identifying legacy mining risks and proposing mitigation.
  • Peat surveys and stability assessments – ensuring appropriate treatment and risk reduction on sensitive ground.
  • Geoenvironmental services.

Frequently Asked Questions

What is geotechnical engineering and why is it important?

Geotechnical engineering is the study and application of soil and rock mechanics in construction and development. It’s essential for assessing ground conditions, designing safe foundations, and preventing failures such as settlement, landslides, or structural collapse.

When should I involve a geotechnical engineer in my project?

The earlier the better. Involving a geotechnical engineer during the planning or feasibility stage helps identify ground-related risks and cost implications early, allowing for better design decisions and fewer surprises during construction.

What are GIR and GDR reports?

GIR (Geotechnical Investigation Report) and GDR (Geotechnical Design Report) are Eurocode 7-compliant documents. The GIR presents the factual and interpretative results of a site investigation, while the GDR outlines the basis for geotechnical design choices.

Do you offer support during construction?

Yes. Our team provides construction-phase support including formation inspections, temporary works certification, and real-time advice on geotechnical issues that may arise during build-out.

Can you help with historic mining risk assessments?

Absolutely. We regularly undertake Coal Mining Risk Assessments (CMRA) to identify risks from historic workings and provide mitigation advice aligned with Coal Authority requirements
