Structure, basements & ground

Retaining Wall Condition and Impact Assessments

Assessment of existing retaining walls affected by a proposal, including condition and capacity.

When this service may be useful

Retaining walls on boundaries and sloping gardens are often affected by extensions, basements and landscaping. Councils and neighbours may want reassurance that the wall will remain stable.

How the work is approached

A structural engineer inspects the wall, records its condition and considers how the proposal changes the loads and drainage it is subject to.

What you receive

You receive a report on condition and risk, with recommendations. Design of new or strengthened walls is a separate instruction.

What we need to start

Site address, photographs, levels and proposed drawings.

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.

Make an enquiry
Who is responsible for a boundary retaining wall?

Responsibility depends on ownership and title. The report addresses the wall's structural condition, not legal responsibility, which should be confirmed by your solicitor.

What information should I provide to get started?

Site address, photographs, levels and proposed drawings.

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.
