Job Description

The Senior Engineer- Overhead Line (OHL) 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.

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:

• 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.

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.

Disciplines‑Specific Responsibilities

Civil / Structural / Mechanical Focus

Applicable to applicants with a civil, structural, or mechanical engineering background involved in OHL projects.

• Model towers or poles using PLS‑TOWER or PLS‑POLE, including strength, stability, and member capacity checks.
• Support or lead foundation assessments and designs (pad, pile, raft, grillage) in collaboration with geotechnical engineers.
• Prepare or review general arrangement drawings, connection details, fabrication drawings, and part lists.
• Assess the structural adequacy of towers/poles for reconductoring, uprating, or retrofit purposes.
• Contribute to constructability assessments including cranage, access, erection sequencing, and outage constraints.

Electrical Focus (Applicable Only to Candidates with an Electrical Engineering Background)

For applicants with an electrical engineering background who possess experience in OHL design:

• Select appropriate conductor types, earth wires, and OPGW based on system requirements and environmental factors.
• Perform insulation coordination studies, including BIL ratings, insulator string design, and strike/arcing distance assessments.
• Review electrical clearances and evaluate thermal ratings of line sections under different loading scenarios.
• Conduct shielding angle analysis, critical span evaluations, and lightning protection adequacy assessments.
• Contribute to EMF, induction, and line loss analysis using applicable software; coordinate termination and bonding interfaces with substation teams.

Qualifications

• Bachelor’s degree in Engineering (Civil, Structural, Mechanical, or Electrical Engineering) is essential.
• A minimum of 8–10 years of relevant experience in HV (132kV+) overhead line transmission design and delivery.
• Chartered or Professional Engineer status (or working towards it) is preferred.
• Demonstrated experience delivering a range of HV OHL projects including new builds, reconductoring, uprating, and asset renewals.
• Proven ability to coordinate across disciplines and review detailed technical outputs to a high standard.

Technical Software and Delivery Capability

Expected to be proficient in key software tools used for transmission line design and capable of overseeing or guiding their application across various project scenarios. While certain tools are essential for core design tasks (e.g., PLS‑CADD and PLS‑TOWER), familiarity with a broader suite of structural, geotechnical, and drafting software is beneficial to support multidisciplinary coordination and delivery efficiency.
