Structure, basements & ground

Geotechnical Desk Studies

A desktop review of ground conditions and geotechnical risks to inform design and any ground investigation.

When this service may be useful

A geotechnical desk study is the first step in understanding ground conditions. It is useful before buying a site, when designing foundations or basements, and when a council or lender asks for evidence on ground stability.

How the work is approached

Published geology, historical maps, borehole records and site information are reviewed to build an initial picture of the ground and the hazards that could affect the proposal.

What you receive

You receive a desk study report with a clear summary of geotechnical risks and a recommended scope for any intrusive investigation. Purchased data reports and site work are confirmed separately.

What we need to start

Site address, site boundary and outline proposals.

We review the site, proposal and planning stage to agree the appropriate scope. The work is carried out by a suitably qualified specialist we appoint, named in your fee proposal.

  2. Site description & history

    Current use, past uses and historical mapping.

  3. Geology & ground conditions

    Published geology, made ground and expected strata.

  4. Hydrogeology

    Groundwater conditions and their relevance to design.

  5. Geotechnical hazards

    Shrinkable clay, trees, slopes, voids and other hazards.

  6. Implications for the proposal

    Likely foundation solutions and construction considerations.

  7. Recommended investigation

    Scope of intrusive investigation, if required.

  8. Conclusions

    Key geotechnical risks and next steps.

YOUR QUESTIONS ANSWERED

Geotechnical desk studies FAQs

Clear answers to help you plan your next step.

Still have a question?

Tell us about the site and we will confirm what is needed and what it should cost.

Make an enquiry
Is this the same as a contaminated land desk study?

No. A geotechnical desk study concerns the ground's engineering behaviour. Contamination is assessed in a Phase 1 contaminated land study; the two can be combined where both are needed.

What information should I provide to get started?

Site address, site boundary and outline proposals.

How is the fee for this service confirmed?

The price shown is a starting estimate for the stated scope. We review the site, proposal, available information and required deliverables, then confirm the fee, exclusions and programme in a written quotation before appointment.

How do your specialists work together on a project?

We bring the relevant planning consultants and specialist providers into a coordinated project team. They work from an agreed brief and current proposal, with dependencies and design changes discussed across disciplines. Each consultant remains responsible for their own professional advice and agreed deliverables.

PART OF A COORDINATED APPOINTMENT

Your specialist evidence, connected.

This service can form part of a wider coordinated planning appointment. We bring the relevant consultants together to work alongside your design team, discuss assessment findings and identify how recommendations affect other reports and the proposal.

Your fee proposal confirms who prepares each document, the information it relies on and the limits of the instruction. A report provides evidence for the council’s assessment; the planning decision remains the council’s. Explore how our consultants work together or discuss the team your project needs.
