scope:

This Company Standard defines in outline the requirements for the management of works to new and existing structures. Details of the actions required are contained within the Specifications, which, together with this Company Standard, form the group of Network Rail Standards for Structures Works, as shown in Appendix B.

This Company Standard applies to all works to new and existing structures that are, or will be, owned or managed by Network Rail and works to new and existing Shared or Outside Party Structures and to those appointed by Network Rail to be responsible for the management of works to such structures. The word "structure" in this Company Standard applies only to structures within the scope of this Company Standard, which are listed in Appendix C.

Each structure shall be assigned an appropriate Structure Category. Structures Works shall be managed in accordance with the requirements of this Company Standard and the Specifications for the assigned Structure Category. The Structure Categories are:

A Bridges and Culverts;

B Retaining Walls;

C Tunnels;

D Earthworks;

E Buildings and station structures;

F Coastal, Estuarine and River Defences;

G Ancillary structures.

Guidance to assist in the assignment of a Structure Category to an individual structure is included in Appendix C. Where justifiable, a Structure Category different from that shown in Appendix C may be assigned to a structure, in which case the justification for this decision shall be recorded.

Within this document, references to Specifications within the Group of Network Rail Standards for Structures Works are made in relation to the Structure Categories, or group of Specifications for Project Management, as listed in Appendix B, i.e. SW(A) to (H), and the Volume number, as well as the Network Rail Standard number.

This Company Standard does not define the organisational and commercial responsibilities for delivering the requirements of this Company Standard.

Purpose

The purpose of this Company Standard is to define the requirements for works to new and existing structures on, over or under Network Rail's infrastructure such that there is no unacceptable risk to safety as a result of their Design or construction.

The Company Standard, when read with the Company Standards and Specifications referenced herein, is compliant with Railway Group Standards as identified in Appendix A.
