Geotechnical

Geotechnical services support foundations, ground conditions, mining legacy, slope stability and development design.

Scope and evidence

Built around planning, development and compliance decisions.

Use this page to understand when the service is usually needed, what evidence is reviewed and what information helps us quote accurately.

  • Planning and regulator context
  • Clear deliverables and next steps
  • Linked services considered early

Geotechnical work is strongest when the investigation is designed around the proposed structures, earthworks and known geological hazards rather than applying a standard set of exploratory holes to every site.

01

When this service is used

Used for foundation design, mining legacy, slope stability, ground risk screening and development design where ground conditions need technical assessment.

Planning and project supportUsed for foundation design, earthworks, slopes, ground improvement, mining legacy and development feasibility where engineering ground conditions need to be understood.
Risk and programme controlEarly geotechnical evidence helps identify poor ground, groundwater, variable fill and other conditions before foundation or earthworks assumptions become embedded in the design.
02

What the report normally includes

  • Ground risk and project scope review
  • Available geology and mining context
  • Development constraint commentary
  • Recommendations for investigation or design input
  • Clear reporting for designers and project teams
03

What we need from you

Providing the right information at the start helps us confirm the scope, quote accurately and avoid back-and-forth once the work is underway.

  • Site address and boundary
  • Proposed development layout
  • Foundation or design questions if known
  • Previous ground investigation reports
  • Planning or warranty provider requirements

Ground investigation should collect the data the designer actually needs

Ground investigation providing the geotechnical evidence needed for design and construction.
What a robust scope should cover
  • Geological setting and anticipated ground model
  • Investigation locations and depths matched to the proposed structures
  • In-situ testing and representative soil or rock sampling
  • Laboratory classification, strength and other engineering tests
  • Groundwater observations and excavation conditions
  • Interpretive recommendations for foundations, earthworks, pavements or further investigation
What the work should leave you with
  • A site-specific engineering ground model
  • Measured parameters for design rather than generic assumptions
  • Identification of ground risks that can affect cost or buildability
  • Recommendations that can be passed directly to structural and civil designers
Why the detail mattersA well-designed investigation can support environmental and geotechnical questions in one mobilisation, but the sampling and test schedule still needs to preserve the objectives of both disciplines.See a combined geo-environmental project →

Useful to know before you enquire

Tell us what is being builtBuilding loads, retaining structures, roads, drainage and earthworks all affect where and how deep the ground should be investigated.
Existing structural assumptions are usefulIf the engineer is considering a particular foundation form or needs specific parameters, share that brief before fieldwork is scoped.
Groundwater can affect construction as well as designGroundwater observations can influence excavation stability, temporary works, drainage and foundation recommendations.
Mining and contamination can be combinedWhere the site has several ground risks, a coordinated investigation can reduce duplicated mobilisation and site disruption.
FAQ

Common questions

What is the difference between geotechnical and contaminated-land investigation?

Geotechnical work focuses on engineering behaviour of the ground, while contaminated-land work focuses on environmental and health risks. They can often be investigated during the same site mobilisation with a coordinated scope.

Can you provide foundation recommendations?

Where the investigation and testing provide sufficient information, the interpretive report can give geotechnical recommendations and parameters for the design team.

Do you need the proposed layout before investigation?

It is highly beneficial. The location and type of proposed structures help target investigation points and depths to the decisions the engineer needs to make.
