Undertake overhead line equipment main steelwork installation under direction
Overview
This standard identifies the competences you need to install overhead line equipment (OLE) main steelwork to pre-prepared foundations under direction. The term main steelwork is used to describe the range of types of masts, cantilevers and portals that provide the structure to support the overhead line equipment.
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, 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 main 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 main steelwork assembly and erection procedures. You will understand the basic principles and processes associated with the erection and assembly of the steelwork and their application. You will know about the ways of handling main 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 finished steelwork structure is produced to the required specification under direction. You will understand the safety precautions required when working at height and with main 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 main 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. This standard does not cover the competencies required by the crane controller whose role would be to ensure that the lifting of the steelwork complies with the predetermined lift plan.

K17 the torque loading requirements of the fasteners and what to do if these loadings are exceeded or not achieved
K18 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)
K19 what equipment operating and care and control procedures are applicable to OLE equipment
K20 the techniques used to position, align, level and adjust the main steelwork
K21 what inspection and testing procedures need to be completed prior to handback
K22 what authorisation procedures are and the limits of your responsibility and authority
K23 the procedures for documentation, control, reporting, and escalation within your organisation
