Structural Movement Monitoring in Camden, London
Structural movement monitoring is required for works that pose risk to adjoining properties under the Party Wall etc. Act 1996, Section 6. Camden Council specifically requires Basement Impact Assessments (BIA) with Burland Scale damage assessments for basement developments.
When It's Needed
| Works Requiring Monitoring | Details | | --- | --- | | Deep excavation | Within 3m of neighbour's building AND below their foundation depth | | Basement construction | Especially deep basements in Camden | | Piling works | Any piling adjacent to existing structures | | Demolition | Particularly reinforced concrete slab cutting | | Underpinning | Foundation stabilisation work | | Large engineering projects | Near listed buildings or sensitive structures |

Frequently Asked Questions
Q: Does Camden require a Basement Impact Assessment?
Yes — Camden Council requires Basement Impact Assessments (BIA) with Burland Scale damage assessments for basement developments. Our monitoring surveys include Burland Scale assessments as standard for Camden projects.
Q: What accuracy can I expect?
Modern monitoring achieves ±1mm accuracy using total stations. Trigger levels are typically set at 1–3mm movement thresholds.
Q: How long does monitoring continue in Camden?
Monitoring typically runs for the duration of the adjacent works plus a post-works period. Basement projects in Camden often require 6–12 months of monitoring to satisfy planning conditions.
Q: What triggers a stop-work alert?
Trigger values are agreed in advance with your structural engineer. If readings exceed these thresholds, you receive an immediate alert so works can be paused and mitigation measures implemented.
