Previous experience with consultancy, contractor or utility in the Power industry.

Previous experience of technical management of a specialist design team

Experience in the field of primary electrical design of HV / EHV AC substations and BoP projects ranging from 11kV to 132kV.

Understanding of industry HV and EHV substation installation standards and specifications.

Ability to take the initiative, demonstrate a pro-active approach to activities, problems and oneself.

Understanding of power cable installation, their requirements and installation parameters i.e. flexible or rigid arrangements, minimum bending radii etc.

Ability to manage the various inter-departmental design interfaces (i.e. structural design, planning, electrical design, CAD technicians) efficiently and effectively to deliver complex designs solutions.

Ability to both write and understand technical documents relating to all aspects of substation electrical plant & equipment.

Have an excellent understanding of risks associated with cabling works. Have working knowledge of the role of the designer under the CDM Regulations 2015.

Ability to complete a designer's risk assessment for designs being developed and produced.

Ability to prioritise workloads in a proactive and organised fashion (using software tools as necessary) to ensure key deadlines are met and reliant parties are kept informed.

The ability to use a proprietary 3D CAD package such as Revit would be desirable.

Detailed Role Requirements

• Be proficient in producing substation electrical layout drawings for

• Where necessary, manage external design suppliers who may be undertaking earthing design or similar activities.
• Undertake lightning risk assessments to the requirements of BS 62305-2.
• Produce above ground earthing layouts to communicate to site installation teams how to connect structures, plant and equipment to the main earthing system in accordance with the relevant standards.
• Produce accurate technical reports, correspondence, documentation, calculations
• Produce specifications for major items of plant such as disconnectors and contribute to the production of specifications for more complex items such as circuit breakers.
• Produce switchroom and control room earthing layout drawings and wall elevations
• Produce switchroom and control room heating, lighting & ventilation layout drawings & elevations including block diagrams to convey LV AC details.
• Produce switchroom and control room cable management drawings and elevations.
• Produce site wide ducting / cabling layout drawings
• Possess a working understanding of G81 standards and DNO's approved equipment registers.
• Produce earthing materials schedules to convey requirements to site installation teams.
• Interface with the procurement team to provide suitable specifications where necessary and approve the cable data sheets prior to purchase ensuring they meet the project requirements, employers requirements and appropriate British and European standards.
• Ensure all required designs, models and drawings have an adequate level of review, checking and approval, including suppliers and subcontractors, according to Quality Assurance processes and in line with a ‘right first time' philosophy.
• Collaborate with designers from other disciplines under coordination of each projects
• Embed safety and sustainability by design on all projects, ensuring compliance with the latest CDM Regulations.
• Analyse and lead the resolution of design challenges.
