HS2 South Sections S1 and S2

Noise and vibration monitoring for a new high-speed rail line

RWDI was engaged to manage noise and vibration monitoring for the construction of two Phase 1 Area South sections (S1 and S2) of the United Kingdom’s new High Speed Two (HS2) passenger line, which, once complete, will connect the nation’s major metropolitan centers. S1 covers the eastern section near Central London between Euston Station and Old Oak Common. S2 continues west from Old Oak Common toward West Ruislip. Our client needed a consultant that could supply, install, and maintain noise and vibration monitoring systems, hosted jointly on a single web-based platform, that would trigger alerts based on project and special case criteria. They needed all data to be downloaded remotely, with advice and recommendations provided whenever an alert occurred. Monitoring reports were provided regularly, as were attended noise and vibration surveys. Additionally, we assisted with stakeholder interactions and supported with consent documentation and compliance.
