2.1 Overview

Operational Property covers a diverse range of assets. This part of the handbook is grouped into three areas: Structures, Fabric and Mechanical and Electrical. Various sections within this part of the handbook are split by these areas to indicate the differing requirements.

2.2 Structure and Fabric Scope:

Operational Property structure types are listed as Structure Categories E and G in Appendix A to NR/L1/CIV/032. The types typically included are:

a) Stations (franchised and Managed by Network Rail);

b) Lineside buildings (critical, non-critical and redundant);

c) Light maintenance depots;

d) Maintenance delivery units;

e) Route Services depots.

The following Operational Property assets included in this part of the handbook are:

f) Buildings (all types);

g) Platforms (operational and non-operational);

h) Footbridges;

i) Canopies (including waiting shelters but excluding footbridge canopies, as these are included as part of the footbridge);

j) Train sheds and Depot Sheds;

k) Elevated vehicle forecourts and ramps;

l) Retaining walls;

m) Access Roads and Car Parks (including Multi-storey);

n) Rafted Structures and Basements;

o) Environs including Access Routes, Curtilages, Fencing & Gates;

p) Ancillary structures:

• Advertising Hoardings;

• Driver Only Operation Equipment;

• Elevated trackside water tank support structures;

• Equipment support structures (excluding Overhead Line Equipment), lighting support structures, cantilever portals (including lattice towers) within Station and Depot environments;

• Equipment support by canopies;

• Hoist or drive support structures;

• Inspection pits set into the track;

• Raised walkways and access systems, including train access in depots;

• Supports to raised track in inspection areas within depots;

• Station Totem Poles;

• Water retaining structures (but not reservoirs).

2.3 Mechnical & Electrical Scope

The Fabric elements of Mechanical & Electrical (M&E) Assets are included in the Structure and Fabric scope. This includes identifying equipment types, installation dates, manufacturer etc. (see measurement rules), but does not include serviceability.

The serviceability elements of M&E are covered through electrical testing and inspection (ET&I) in accordance with BS 7671. For Franchised estate this is undertaken by the Franchise Operator on a five-yearly cycle for Stations and three yearly for Depots.

NOTE: The requirements for Examinations do not apply to Operational Property assets owned or managed by an Outside Party.

Purpose

This module sets out the examination requirements for Operational Property assets, to mitigate the risk of functional failure of an Operational Property asset which might result in health, safety, environmental or operational incidents.

The top risks identified in Operational Property are due to failure of assets leading to:

a) loss of safe environment; including objects falling from height and Mechanical & Electrical infrastructure failures;

b) slips, trips and falls at building assets;

c) train collision.

The output from examinations will be used to derive future budgets through scoping of planned preventative maintenance works, demonstrate examination compliance with the Office of Rail and Road (include other key information that examinations are used for).
