• Cooling towers, condenser-water systems, water treatment interfaces, strainers, and associated pumps and VFDs.
• N+1 or N+2 redundancy strategies, automatic and manual plant sequencing, lag/lead rotation, and emergency changeover.
• Process chilled water versus comfort chilled water loops, if separately piped.
• Chilled-water thermal storage, free-cooling / waterside economizer, and plant optimization, if present.
• Refrigerant management, leak detection, EPA Section 608 compliance, and recovery practices.
• Steam generation and distribution,condensate return, traps, PRVs, and associated safety devices.
• Domestic and process water, industrial water, cooling-tower makeup, and backflow prevention.
• Pumps, motors, VFDs, heat exchangers, expansion tanks, chemical-treatment skids, and associated instrumentation.
• Emergency generators and UPS interfaces only to the extent they support HVAC/utility continuity, in coordination with electrical operations.
• Utility metering, submetering, and data used for energy and capacity planning.
• Campus BMS/BAS and associated field controllers.
• Graphics, alarm management, point-to-point integrity, trending, historian data, and operator workstation standards.
• Provide direct supervision to the HVAC lead, Chiller Plant lead, Utilities Maintenance lead, and BMS lead, and through them to the technicians, operators, and specialists in each group.
• Establish shift coverage, on-call rotations, overtime plans, and surge staffing for planned outages, seasonal peaks, and emergency events.
• Set daily and weekly priorities that balance preventive maintenance, corrective work, projects, and research-driven requests.
• Hire, onboard, coach, evaluate, and, when necessary, discipline personnel in accordance with company policy and applicable labor agreements.
• Build cross-training so that no single person is the sole source of knowledge for a critical plant or control sequence.
• Hold toolbox talks and pre-job briefs covering LOTO, confined space, hot work, elevated work, refrigerant handling, and chemical hazards.
• Own day-to-day operating posture of the central chiller plant, including load following, equipment rotation, condenser- and chilled-water temperatures, approach temperatures, and tower performance.
• Ensure HVAC systems serving laboratories and controlled environments maintain specified temperature, humidity, air-change, and differential-pressure ranges.
• Direct response to environmental excursions, plant trips, loss of redundancy, and utility interruptions; restore service and support quality impact assessments.
• Coordinate seasonal changeover, winterization, and peak-load readiness reviews well ahead of weather and occupancy changes.
• Own the preventive, predictive, and reliability-centered maintenance program for assigned assets in the site CMMS (Maximo)

• Specify and oversee vibration analysis, oil analysis, infrared thermography, ultrasonic leak detection, tube inspections, and other PdM methods.
• Manage spare-parts strategy for long-lead chiller, tower, AHU, and controls components, including critical-spares min/max levels.
• Ensure the BMS is maintained as an operational tool and, where applicable, as a GxP-relevant data source: accurate graphics, validated alarm paths, and reliable historian data.
• Establish alarm philosophy: prioritization, deadbands, delay timers, notification paths, and after-hours escalation so operators can act rather than drown in nuisance alarms.
• Review trends after excursions and after significant sequence or setpoint changes; document findings.
• Operate assigned systems in a manner consistent with cGMP expectations for facilities supporting pharmaceutical R&D, including good documentation practices (GDP).
• Ensure refrigerant, pressure-vessel, boiler, backflow, and water-treatment records meet EPA, ASME, and local jurisdictional requirements.
