scope:

LU Category 1 Standards 1-050 "Civil Engineering - Common Requirements" and 1-154 Permanent Way System - Strategy and Interfaces, define the requirement for noise and vibration assessments to be carried out.

This Guidance applies to all new operational assets, assets undergoing major upgrade works, or assets being brought back into use after a period of five years or more.

The assessment methodologies and criteria described in this document are for residential dwellings. It is recognised that other noise sensitive receptors exist e.g. schools, offices, hospitals, hotels, theatres, churches etc. Assessment methods and criteria for these receptors should be determined on a project by project basis as applicable. It is likely that similar assessment methodologies would apply for these receptors but the criteria may differ (example criteria can be found in BS 8233:1999 Sound insulation and noise reduction for buildings - Code of practice).

Please note that the assessments and criteria provided in this guidance document are not extensive. Individual project stakeholders and local authorities may require further assessments and may apply different criteria.

Purpose

The purpose of this Guidance is to define noise and vibration assessment methodologies and criteria that should be used in the design of new operational assets. LUL assets are often in close proximity to noise and vibration sensitive receptors, e.g. residential properties, offices, theatres etc. When noise and vibration is not controlled LUL receives complaints from these receptors which can be expensive to rectify once an asset is built and operational.
