Noise, acoustics, and vibration monitoring for the upgrade of a station in the London Underground
The Bond Street Station Upgrade project involved the construction of several new elements, including a new station entrance, escalator hall, lifts to enable step free access to station platforms, link to the new Crossrail station, and connection improvements between London Underground lines.

The Challenge
The site for the upgrade is on Oxford Street, directly opposite the current Bond Street Station entrance. The area is amongst receptors sensitive to noise and vibration, and there are also several high profile properties nearby the upgrade site. The RWDI team was commissioned to carry out noise and vibration assessments.
Our Approach
RWDI’s team of noise, acoustics, and vibration experts:
- Prepared Section 61 consent application documentation to ensure regulatory compliance.
- Conducted careful noise assessments for construction activities like 24/7 tunneling works and building demolition to safeguard the sensitive surrounding area.
- Completed baseline noise monitoring to better identify when noise exceeds acceptable levels.
- Leveraged noise impact studies to predict the impacts stemming from traffic diversions and determine when compliance noise monitoring would be necessary.
- Conducted vibration monitoring at various project stages to ensure the integrity of the station and nearby Thames Water services.
- Developed detailed modeling to specify acoustic performance requirements of cladding materials for the 6-storey over site development to reduce breakout noise from nearby activities.
The Outcome
The upgrades increased the capacity of Bond Street Station’s entrances and exits by 30 % and successfully made the station step-free in a smooth construction process.
