- Ensure installation works comply with approved drawings, specifications, ITPs, RAMS, manufacturer instructions, and relevant transmission standards.
- Take ownership of mechanical QA/QC activities including inspections, quality walk-downs, ITP compliance, punch listing, snagging, and management of non-conformances through to close-out.
- Monitor workmanship and construction progress, identifying potential delays, installation issues, design clashes, or quality concerns, and implementing corrective actions where required.
- Coordinate closely with electrical, civil, and commissioning teams to ensure interfaces between packages are effectively managed.
- Conduct toolbox talks, daily briefings, and site inspections while promoting a strong health, safety, environmental, and quality culture.
- Ensure works are carried out in accordance with RAMS, permit-to-work systems, project HSEQ procedures, and applicable National Grid requirements.
