Frequently Asked Questions
Q: When do I need monitoring in Wembley?
Monitoring is typically required when Party Wall awards specify monitoring of adjacent properties, when planning conditions require it, or when visible defects suggest subsidence or structural movement. Wembley's dense residential and commercial development requires careful monitoring during adjacent works.
Q: What accuracy can I expect?
Modern monitoring achieves ±1mm accuracy using total stations. Crack gauges can detect 1–3mm movement with precision studs. Trigger levels are typically set at 1–3mm.
Q: How long does monitoring continue?
Monitoring typically runs for the duration of the adjacent works plus a post-works period. Basement projects often require 6–12 months. Confirm the programme with your structural engineer.
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.
