The project

Context

My first major international project placed me inside a hyperscale data center environment where quality, traceability and coordination directly affect commissioning risk.

The programme involved critical power infrastructure across multiple data center buildings, requiring disciplined installation control and clear interfaces between electrical systems and construction work fronts.

Responsibility

My role

  • Supervised installer-side electrical works across multiple buildings.
  • Coordinated workface progress and resolved installation interface constraints.
  • Supported pre-commissioning, testing, QA/QC, snag management and handover documentation.
Technical delivery

Scope

  • UPS systems, diesel generators and automatic transfer systems.
  • LV/MV switchgear, chillers and power distribution panels.
  • MV/LV cable containment, cable pulling, terminations and earthing.
  • Insulation resistance testing, redlines and system traceability.
Contribution

What I improved

  • Strengthened field visibility through systematic progress and quality follow-up.
  • Maintained redline and handover information as work progressed.
  • Built a strong understanding of mission-critical sequencing and commissioning dependencies.
Reflection

What this project taught me

Critical infrastructure taught me that small installation decisions can have large downstream consequences. Discipline and traceability are not administrative tasks — they are part of engineering quality.
