Structure, basements & ground
Prediction of ground movement from excavation or foundations and the likely effects on neighbouring buildings.
Where a basement or deep excavation is proposed close to other buildings, councils expect the likely ground movement and its effect on neighbours to be predicted. The assessment is often part of, or supports, a basement impact assessment.
Movements are estimated using recognised methods and the available ground data, then compared with the sensitivity of each adjoining building to give a predicted damage category. Mitigation and monitoring measures are identified where needed.
You receive a report setting out the method, predicted movements and damage categories, with clear assumptions and limitations. Detailed numerical modelling is quoted separately where the site warrants it.
Proposed drawings, ground investigation data and details of adjoining buildings.
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.

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.
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
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.
