Assessment of slope stability where development affects or relies on sloping ground.
When this service may be useful
Development on or near sloping ground can be required to show that it will not cause instability, either during construction or in the long term. Councils may ask for this evidence on sloping sites, cuttings and embankments.
How the work is approached
The slope is assessed using site levels and ground data, the effect of the proposed works is analysed and measures to maintain stability are identified.
What you receive
You receive a report with the analysis, conclusions and recommended measures, and any further investigation needed.
What we need to start
Site survey with levels, proposals and any ground investigation information.
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.

Is a slope stability assessment part of a basement impact assessment?
Slope stability is one of the screening topics in most basement guidance. Where screening identifies a risk, this assessment provides the detailed evidence.
What information should I provide to get started?
Site survey with levels, proposals and any ground investigation information.
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.
