Job description:
The Principal Overhead Line (OHL) Engineer provides senior technical leadership and delivery capability across a broad range of transmission line projects from 132kV to 765kV. This includes greenfield projects, asset upgrades, reconductoring, thermal uprating, foundation and structure strengthening, line cut-ins, and asset renewal schemes. The role involves hands-on design, technical review, and interdisciplinary collaboration across project stages from concept to construction. Key responsibilities and activities include:
- Planning, scheduling, and execution of HV transmission line projects including:
- Prepare cost estimates, project budgets, and resource allocation plans.
- Coordinate with project managers, clients and other stakeholders to ensure project requirements are met.
- Coordination and technical leadership in the delivery of HV transmission line engineering and design projects/packages.
- Developing transmission line alignments, profiles, and structure spotting using PLS-CADD.
- Performing sag-tension analysis and validating clearances in accordance with relevant standards (e.g. EN 50341, NG TS 2.04).
- Preparing and reviewing design deliverables including plan/profile drawings, stringing charts, structure schedules, and loading reports.
- Assessing tower and pole structure loading and coordinating foundation designs with geotechnical inputs.
- Leading and/or contributing to the following project types:
- New transmission line designs (greenfield)
- Reconductoring and sag-tension recalculations
- Uprating and clearance improvement studies
- Structure/pole strength assessments and retrofits
- Foundation strengthening (e.g., pile extensions, grillage upgrades)
- Line cut-ins, tee-offs, and route deviations
- Tower/pole replacements and asset renewal
- OPGW or earthwire replacement and shielding reviews
- Participating in design reviews, QA/verification processes, and constructability assessments.
- Supporting delivery of construction-ready drawings and material schedules.
- Coordinating with drafting, structural, civil, electrical, and geotechnical teams for integrated design outputs.
- Providing guidance and mentoring to junior engineers and contributing to continuous improvement through lessons learned and design innovation.
