Undertake overhead line equipment small part steelwork installation under direction
Overview
This standard identifies the competences you need to install overhead line equipment (OLE) small part steelwork under direction. The term small part steelwork is used to describe items of equipment that are assembled and fitted to the main steel structures such as cantilever assemblies, headspans, cross span wires, registration arms, bridge/tunnel supports and security guards.
The definition of OLE is an arrangement of wires, suspended over the railway line, for supplying electricity to electric trains, together with associated fittings, insulators and other attachments including feeders, autotransformer feeders, overhead line switches, jumpers and return conductors. This equipment together with its structures, foundations, and lineside switching stations is described collectively as Overhead Line Equipment.
To prove competence in this standard you shall need to demonstrate your ability to complete the small part steelwork installation, renewal, enhancement or modification activities in accordance with directions from a specified competent individual.
Your underpinning knowledge will provide a good understanding of your work, and provide an informed approach to applying steelwork assembly procedures. You will understand the basic principles and processes associated with the assembly of the small part steelwork and their application. You will know about the ways of handling steelwork, the means of fixing them in position as well as the care and use of the tools and equipment in adequate depth to provide a sound basis for carrying out the activities and ensuring the installed small part steelwork is produced to the required specification under direction. You will understand the safety precautions required when working at height and with steelwork components and their associated tools and equipment. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
Your responsibilities will require you to comply with organisational policy and procedures for the safe installation of the small part steelwork and the associated assembly activities to be undertaken and to report any problems with the component parts, equipment or installation activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work on defined tasks under the direction of a specified competent individual.
Performance criteria
You must be able to:
P1 maintain safe working practices and comply with all relevant health and safety regulations, directives, and guidelines
P2 complete activities under the direction of competent personnel and using the correct tools and equipment
P3 follow the relevant renewal, installation or enhancement documentation for the small part steelwork to be renewed or installed as directed
P4 carry out the installation activities within agreed timescale using approved materials and components and methods and procedures and under direction
P5 undertake activities within the limits of authority, following recording, reporting and escalation procedures
P6 assist with the production of accurate records of work undertaken

K12 the purpose for the different types of design drawings used in OLE steelwork installation (such as layouts and cross section diagrams and OLE system design range (such as OLEMI))
K13 how the OLE is designed to function under normal operating conditions
K14 what each of the OLE component parts contribute to the overall operation of the system
K15 what storage and handling precautions have to be taken to protect easily damaged components (such as insulators)
K16 what terminology and methods are used to identify OLE small part steelwork and to describe the operational status of the steelwork
K17 tools, plant and equipment used in the installation process and how to use them
K18 the torque loading requirements of the fasteners and what to do if these loadings are exceeded or not achieved
K19 the types of tools and instruments used to position, secure and align the steelwork (such as podgers, spanners, wrenches, sockets, torque wrenches, levels, alignment and laser devices)
K20 the safe methods of securing the small part steelwork components (such as locking devices and pins)
K21 what equipment operating and care and control procedures are applicable to OLE equipment
K22 the techniques used to position, align, level and adjust the small part steelwork
K23 what inspection and testing procedures need to be completed prior to handback
K24 what authorisation procedures are and the limits of your responsibility and authority
K25 the procedures for documentation, control, reporting, and escalation within your organisation
