This module applies to all categories of OCS work but is scalable to the level of assurance required for the work being carried out.

The module outlines the requirements for the control of installation work and the only variation between categories will be the extent of documentation required to demonstrate compliance.

This module covers the requirements to demonstrate that the risks associated with installation are managed effectively.

The main risks are associated with the competence of the installation personnel, installation methodology, the management of field changes, supplier self-assurance, and record keeping.

This module provides the requirements for Network Rail installation assurance which should be applied in conjunction with existing Network Rail requirements for construction management.

These requirements may be used to assist with the creation of scope specific contractual requirements related to installation quality. It is expected that the contract requirements will detail timescales, consequences of failing to adequately carry out assurance activities and the commercial implications of defective installation.

Occupational health and safety requirements for construction are not included in this module.

Purpose
