scope:

This Standard applies to all proposed changes to Stations Assets within the APD Stations Directorate, which may have a material effect on the physical form, function or performance of the Asset, or an impact on the whole life management of that Asset.

Within the terms of this scope a change may include, but is not limited to:

a) A physical modification to a station asset.

b) A change to asset maintenance or engineering standard, process, practice, test, schedules or periodicities.

c) A change to a station asset maintenance stock system, stock holding, equipment standard or setting, or procurement arrangement.

d) A change to an equipment overhaul or spare part specification or standard.

e) A temporary change to a station asset for authorised trials, test or R&D purposes.

f) A change of the supplier of a safety critical part or services associated with a safety critical part i.e.: repair, overhaul or manufacture.

g) Provision of a component or part for which the original design details are not available. (a process commonly known as reverse engineering as defined in LU Standard 1-180).

Incorporated within this scope is the provision of engineering support for minor works, arising from scheduled maintenance work, inspection and condition monitoring. That may entail minor changes to asset design arrangements to facilitate completion of such work. This type of issue will be a one off arrangement but may affect a number of assets or the design and maintenance of assets types across Stations.

Purpose

Encompassing Asset changes within Lifts & Escalators, Communications & Electrical Systems, Pumps, Premises Equipment, Fire Systems & Mechanical Systems.
