    • 3. Site Support & Construction Supervision
  • Provide technical leadership during project execution, including piping installation, mechanical equipment erection, and commissioning.
  • Ensure construction work aligns with engineering designs, specifications, and safety regulations.
  • Conduct pre-commissioning and commissioning tests for piping and mechanical systems, including hydrostatic, pneumatic, and leak testing.
  • Troubleshoot complex mechanical and piping failures, alignment issues, vibration concerns, and process inefficiencies.
  • Supervise as-built documentation and modification requests based on site conditions.
  • Ensure compliance with welding, NDT, and quality control requirements for piping and mechanical structures.
    • 4. Vendor Coordination & Procurement Support
  • Manage relationships with vendors, suppliers, and EPC contractors, ensuring equipment and materials meet technical requirements.
  • Review and approve vendor proposals, technical bids, and engineering documentation for compliance.
  • Lead technical discussions, vendor evaluations, and cost optimization strategies.
