scope:

The scope of reporting is limited to:

a. Residual Life of the Asset base;

b. Failures to meet Required Duty that result in Functional Condition Concerns:

• Legal non-compliance; and/or

• Safety risks that may result in customer fatalities and/or injuries, which require either control or mitigation to achieve risk levels of ALARP or better; and/or

• Extraordinary maintenance and/or

• operational activities, outside of the maintenance regime, which are uneconomic and/or unsustainable; and/or Performance Risks of £250k or more per year;

c. Degradation Concerns.

The scope of reporting includes software and firmware, but excludes:

a) Information and documentation used to support management of a physical Asset;

b) Any aspect of failure to meet Required Duty that does not result in any of the business impacts covered by 2.2 above (i.e. transient defects).

Notes Any exceptions to 2.3 are explicitly listed in the Attachments to the Standard. For simplicity the term "engineering Asset" is shortened to "Asset" within the Standard and accompanying Guidance Document. Similarly the term "Asset" shall be interpreted to include "Asset systems", "Asset sub-systems" or "part of an Asset" as appropriate.

Purpose

The purpose of this Standard is to define the requirements for the annual reporting and certification of the condition of engineering Assets owned by London Underground (LU).

The Asset Condition Reports and Asset Safety & Management Certificates together:

• Provide assurance to the LU Executive and other stakeholders that the Assets are of known condition and are fit for purpose;

• Allow Asset condition trends to be monitored;

• Identify residual safety and performance risks and their associated mitigations and controls;

• Inform the Asset investment planning process.

Notes

Compliance with this Standard supports a written notice against Standard 1-031 Asset Condition Assessment and Certification, which is superseded by this Standard.

ACR Guidance Document, G-042, provides guidance, references and explanations to enable satisfactory completion of an ACR.
