• Lead functional performance testing and integrated systems testing involving mechanical failure scenarios.

Documentation & Reporting

Develop and manage commissioning documentation, including:

• Commissioning plans and schedules
• Mechanical test procedures and functional performance scripts
• Method statements and risk assessments
• Final commissioning reports, as-built records and handover documentation
• Provide clear, accurate progress, risk and readiness reports to project and client stakeholders.

Standards & Compliance

• ASHRAE (including TC 9.9)

• CIBSE, SMACNA, IPC

• IEC, ISO, and local authority requirements

• Uptime Institute Tier Standards

• TIA-942 and client-specific hyperscale standards

• Support third-party audits, peer reviews and certifications where required.

Factory & Site Acceptance Testing (FAT & SAT)

• Plan, coordinate and lead FAT and SAT activities for mechanical equipment and packaged systems.
• Review vendor submittals, test data and corrective actions to ensure equipment readiness for site installation and integration.
• Witness performance testing of major plant (chillers, PAHUs, cooling towers, packaged plant).

Risk Management & Troubleshooting

• Identify technical, schedule, operational and safety risks related to mechanical commissioning.
• Implement mitigation strategies and lead root-cause analysis and troubleshooting to resolve issues efficiently.
• Support rapid issue resolution in live or partially energized data hall environments.

Health, Safety & Environmental Compliance

• Demonstrate a strong understanding of mechanical and process safety, particularly when working with:

• Pressurized systems

• Rotating equipment

• Chemical treatment systems

• Live data center environments

• Ensure all commissioning activities comply with health and safety regulations, permit-to-work systems, confined space requirements and lock-out/tag-out (LOTO) procedures.

• Promote and enforce a strong safety culture across all commissioning activities.

Leadership & Team Development

• Lead and support contractors, and subcontractors.
• Provide technical guidance, training and oversight to ensure consistent commissioning quality and hyperscale delivery standards.
• Interface effectively with client operations teams to ensure a smooth transition to steady-state operations.

Continuous Improvement

• Adhere to company policies, procedures and quality management systems.
• Capture lessons learned and promote continuous improvement in commissioning methodologies, energy performance and reliability outcomes across hyperscale data center projects.
