abnormalities.
• Support root-cause analysis and implementation of corrective actions.
• Review preventive and predictive maintenance programs.
• Develop and review Standard Operating Procedures (SOPs), Maintenance Procedures (MOPs), and Emergency
Operating Procedures (EOPs).
• Monitor mechanical equipment performance and identify opportunities for optimization.
• Support capacity planning and mechanical infrastructure upgrades.
• Maintain accurate equipment records, drawings, specifications, and maintenance documentation.
BMS & Controls
• Coordinate with BMS/Controls engineers to ensure proper monitoring and control of mechanical systems.
• Review mechanical control sequences and points lists.
• Verify alarms, setpoints, interlocks, equipment status, and operating sequences.
• Monitor critical parameters through BMS/EPMS and other facility monitoring systems.
• Support development and testing of automatic changeover and failure-response sequences.
Energy Efficiency
• Monitor mechanical system energy consumption and operating efficiency.
• Support initiatives to reduce cooling energy consumption and improve PUE.
• Analyze chiller, pump, cooling tower, and CRAH/CRAC performance.
• Identify opportunities for free cooling, variable-speed operation, optimized chilled-water temperatures, and
other energy-saving measures where applicable.
• Support measurement and verification of energy-saving initiatives.
Safety & Compliance
• Ensure compliance with mechanical, HVAC, fire/life-safety, environmental, and occupational safety
requirements.
• Participate in risk assessments and permit-to-work processes.
