• Provide technical input to tower loading calculations and structural design teams.
• Lead PLS-CADD modelling and transmission line layout development for complex projects.
  
  2. Transmission Line Calculations and Technical Studies
• Perform and review key electrical and mechanical transmission line calculations including:
• Electrical studies: ampacity corona and radio interference electric field analysis line impedance shielding angle and lightning performance.
• Mechanical studies: sagtension calculations conductor blowout loading cases (wind ice temperature) and clearance verification.
• Structural interface: tower loading trees load combinations and coordination with structural teams for tower and foundation design.
• Engineering analysis is typically performed using PLS-CADD PLS-TOWER ETAP or equivalent transmission line design/studies software according to each discipline.
  
  3. Project Engineering and Multidisciplinary Coordination
• Support or lead (if required) engineering delivery of overhead line projects across multiple project phases.
• Coordinate with structural geotechnical power systems and environmental teams to deliver integrated solutions.
• Contribute to feasibility studies route corridor assessments and technical evaluations to identify preferred transmission line layouts.
• Provide technical input to proposals project planning and engineering deliverables.
  
  4. CAD & Drafting Coordination
• Guide and coordinate CAD designers and drafters in the preparation of drawings and models.
• Review and validate drawing quality consistency and compliance with standards ensuring timely production and revision of drawings aligned with project delivery milestones.
  
  5. Standards Compliance and Technical Assurance
• Ensure designs comply with relevant standards including IEC IEEE EN/British Standards and National Grid or DNO specifications.
• Participate in design reviews technical verification and internal quality assurance processes.
  
  5. Technical Documentation
• Prepare and review key engineering documentation such as:
• Transmission line design reports and calculation notes
• Tower spotting reports and sag-tension charts
• Technical specifications BoQs and construction drawings
• Documentation should support design reviews client approvals and project audits.
