Crossrail C510

Specialists were needed to manage requirements with respect to the noise and vibration aspects of the contract. The work necessitated complete familiarity with assessments of construction noise and vibration, including the preparation of Section 61 consent application documentation and compliance studies against the project’s commitments.

RWDI’s noise, acoustics, and vibration team was chosen to:

• Develop a bespoke groundborne noise vibration prediction model for work taking place within shafts and tunnels to manage impacts on building occupants in the vicinity and assist in community relations activities.
• Provide the detailed design of major noise and vibration mitigation measures to facilitate continuous 24hr work.
• Specify and procure, as part of the enquiry and tender evaluation team, a giant acoustic enclosure constructed at the Whitechapel site.
• Facilitate the deployment of continuous real-time noise monitoring systems capable of alerting site personnel in advance of any breaches.
• Streamline and automate repetitive works, such as weekly compliance reporting, to provide best value to the client.
• Devise an innovative groundborne noise and vibration Mitigation Plan as a means of preventing legal intervention by the Local Planning Authority, which otherwise likely would have sought legal powers to curtail the working hours to unworkable limitations.

The C510 contract was highly successful in terms of noise and vibration, setting new standards in terms of best practice and innovation. The efforts of our noise, acoustics, and vibration team helped to build trusted relationships with key stakeholders, enabling 24/7 unhindered work despite closeness to sensitive receptors. This project was the 2018 Association of Noise Consultants (ANC) Award Winner in the Environmental Noise Category.
