Environment Crossrail Ltd is a wholly owned subsidiary of Transport for London (TfL) and is committed to implementing all the provisions in theTfL Health, Safety and Environment Policy. Our approach to the environment is set out in the Crossrail Environmental Policy and our Environmental Objectives. Crossrail Environmental Objectives To support the implementation of the Transport for London (TfL) Health, Safety and Environmental Policy and to assist in monitoring of environmental performance, TfL has set a number of Environmental Objectives and Key Performance Indicators

Noise and vibration

Crossrail recognises that the route of the railway runs close to local communities and to some residential areas. Construction works and the running of an operational railway will contribute to noise in the local environment. Where the potential for significant impacts from noise are predicted, Crossrail will implement measures to control and limit noise as set out below.

Pre-construction

The Crossrail Environmental Statement, supported by the Specialist Technical Report: Assessment of Noise and Vibration Impacts, included comprehensive assessments of noise and vibration from construction and operation. The assessments predicted the likely significant noise and vibration impacts caused by construction works and the railway system once up and running. Proposed methods for mitigation were included where appropriate.

Mitigation

As the project design progresses this work will continue to ensure that we are aware of the potential for noise and vibration and that we will continue to address the issue and take appropriate steps to control it. Construction works on site will be controlled in accordance with a consent obtained under legislation set out in the Control of Pollution Act 1974.

This comes in the form of the Environmental Minimum Requirements and four separate information papers that have been published to cover the main aspects as follows:

Construction Noise

Measures for the control of construction noise are set out in the Environmental Minimum Requirements. Further information on the Crossrail Noise & Vibration Mitigation Scheme, which addresses the issue of noise insulation and temporary rehousing, is set out in Information Paper D9.

Groundborne Noise

Information Paper D10 explains the measures that will be used to control the transmission of groundborne noise from both the operational railway and the railway used for the construction of the Crossrail tunnels.

Fixed Plant Noise

Information Paper D25 explains the measures that will be used to control noise from items of machinery that are required to operate the railway that remain fixed in place such as ventilation shafts along the tunnelled section and transformer stations.

Surface Railway Noise

Information Paper D26 explains the measures that will be used to control noise related to the running of Crossrail trains on above-ground sections of the track.
