- Support the management of technical queries (TQs), RFIs, and design change processes to ensure timely resolution.
- Review the engineering deliverables in view of the NG technical specifications, standards, and stage-gate requirements.
- Coordinate the management of design risks and opportunities, ensuring integration with the Project Risk Register.
- Provide concise reporting to the Project leadership on interface status, emerging risks, and required interventions.
The service is intended to strengthen technical cohesion across the project, ensuring a coordinated, and programme-aligned design prior to transition into construction.
Qualifications- Relevant degree in Engineering or a Project Management Discipline.
- Extensive experience in technical integration and interface management within major infrastructure projects.
- Proven ability to manage cross-discipline design coordination and resolve technical queries in complex delivery environments.
