Innovative noise and vibration monitoring deemed to be “world class”
Construction of the new Crossrail Paddington Station in Westminster involved a new 240m long and 30m deep three-level box. The project was constructed over a six-year period in close proximity to noise and vibration sensitive assets, including occupied multi-storey office blocks, a hotel, and heritage buildings.

The Challenge
For the duration of the project, our client required continuous monitoring of construction dust, vibration, and noise at local sensitive receptors, including a number of special case receptors and residential properties. This required careful liaison with private and public stakeholders to arrange access for scheduled and unscheduled site visits for equipment maintenance and re-location purposes. The client turned to the noise and vibration experts at RWDI to get the job done.
Our Approach
Our team:
- Undertook over 100 attended noise and vibration surveys, focusing on the commencement of major phases of construction.
- Managed and reported monitoring data via monthly and bi-weekly reports.
- Carried out detailed vibration risk assessments for sensitive receptors, including heritage assets.
- Installed web-based vibration monitors linked to flashing beacons to provide instant notifications when vibration thresholds were exceeded during particularly sensitive works.
- Established external trigger action levels for noise and vibration at each receptor.
- Developed a major mitigation protocol that considered all constraints.
- Performed community liaison activities to keep affected parties informed of the technical work and mitigation measures.
The Outcome
Our monitoring results and mitigation work enabled the work to be completed more effectively. Crossrail published our efforts on their Legacy Learning website, recognising the innovative work as “world class”.
