scope:

This standard applies to all project works that renew, replace, alter, decommission or remove existing assets or provide new assets on Network Rail infrastructure.

It also applies to those project works that have the capacity to affect assets that are adjacent to but not the subject of the project works, for example a new thrust-bored culvert affecting stability of the track and cable runs.

It does not apply to the transfer of responsibilities on the expiry of a contract for maintenance.

Purpose

This standard sets out the requirements for introducing new assets or affecting existing assets on Network Rail infrastructure; it is supported by NR/L3/EBM/089 Asset Management Plan.

It defines the process for:

• the safe and effective maintenance of all operational assets before, during and after project work and;

• controlled arrangements for the management of assets undergoing change.
