Monitor EPC installation of GIS/AIS, transformers, MV switchgear, protection panels, AC/DC systems, and cabling.

Verify work compliance with IFC drawings, project specifications, OEM manuals, and IEC/IEEE standards.

Identify design deviations, technical risks, and non-conformities and escalate accordingly.

Review EPC shop drawings, wiring diagrams, protection schemes, SCADA mappings, and installation procedures.

Protection & Control Oversight

Review protection coordination studies, HV equipment installation, relay settings, and logic designs.

Verify implementation of interlocking schemes and control logic.

Review and approved test procedures, and witness protection testing (secondary injection, relay configuration, trip circuits, interlocking, SCADA point checks).

Ensure EPC testing aligns with grid code and utility requirements.

QA/QC & Testing Verification

Monitor EPC QA/QC activities according to FQP, CL, ITPs and approved QA plans.

Witness insulation resistance tests, Hi-Pot tests, contact resistance, transformer acceptance tests, MV switchgear tests, and integration tests.

Review NCRs, corrective actions, and verify technical closure.

Confirm accuracy of as-built drawings.

Review and approved QA/QC documents ITP, FAT, FQP, CL, MS and material submittal.

Perform Site inspection and issue IR and MIR for material inspection.

Commissioning & Energization Oversight

Review EPC pre-commissioning and commissioning procedures for Electrical systems.

Validate readiness for energization through systematic checks and walkdowns.

Track and verify closure of commissioning punch lists.

Support Owner with energization readiness documentation.

Interface Coordination

Coordinate substation interfaces with civil, Electrical, commissioning SCADA, telecom, and grid operator teams.

Ensure EPC provides accurate interface details and proper sequencing.

Resolve multidisciplinary technical conflicts.

Progress Verification

Verify EPC progress (installation, cable pulling, terminations, testing) against planned milestones.

Validate progress claims with physical evidence.

Prepare daily/weekly reports on progress, quality, testing, risks, and required actions.
