Control Philosophy and Sequence of Operations

• Maintain a detailed understanding of the approved control philosophy, sequence of operations, cause and effect relationships, equipment interlocks, permissive, operating limits, alarm thresholds and fail-safe behaviors of critical facility systems.
• Review and validate control sequences for critical electrical and mechanical infrastructure, including chillers, cooling distribution units (CDUs), pumps, heat exchanges, cooling towers, CRAH/CRAC units, fan coil units, VAV systems, valves, dampers and other associated equipment, as applicable to the facility design.
• Verify that automatic control, lead-lag operation, duty standby rotation, equipment staging, alarm escalation, failover and recovery sequences function as intended. Assess the potential operational impact of control system faults, sensor failures, communication losses and incorrect control commands.
• Ensure that control logic and operating sequences remain aligned with approved design intent and operating procedures.

Alarm Management and Critical Environment Monitoring

• Maintain effective BMS alarm management to ensure critical events are detected, correctly priorities and presented to operators in a clear and actionable manner.
• Review alarm configuration, priorities, thresholds, delays, deadbands, latching, suppression and escalation arrangements. Identify nuisance alarms, alarm floods, recurring alarms, alarm masking and conditions that may prevent operators from recognizing a genuine critical event.
• Analyse BMS trends and historical data to identify abnormal operating patterns, equipment degradation, control instability, excessive cycling, temperature excursions and other conditions that may affect facility resilience or customer service.
• Work with the operations team to improve alarm response procedures, operating instructions and troubleshooting guidance.
• Ensure alarm related operational risks are understood and the critical alarms have clear response expectations.

Critical Infrastructure Interfaces and Integration

• Maintain operational oversight of BMS integration with relevant facility systems, including electrical power monitoring systems, UPS, Generators, Chillers, Cooling Tower, CDU, switchgear interfaces, cooling systems, environmental monitoring, leak detection.
• Verify the accuracy and consistency of information exchanged between integrated systems, including equipment status, alarms, measurements, commands and health communication.
• Investigate interface failures and coordinate corrective action with the relevant system owners and vendors.
• Ensure system integration does not introduce unintended control dependencies, single points of failure or loss of operational visibility.
• Support the assessment of degraded operating conditions, including loss of BMS servers, network segments, controllers, gateways or external interfaces.

Incident Management and Technical Investigation

• Provide specialist support during BMS, BAS related incidents, cooling system instability, liquid cool system incident, unexpected equipment operation, BMS communication failures, control-sequence failures, loss of monitoring, loss of control capability.
• Analyse alarm logs, event sequences, trends, controller histories, available equipment data to establish the sequence of events and identify contributing factors.
• Participate in incident reviews, technical discussions and operational drills involving BMS, Control system failures.
• Ensure lessons learned are translated into improvements to control logic, alarm configuration, monitoring coverage, operating procedures and system resilience where appropriate.

Maintenance, Testing and Change Management

• Support, planned preventive maintenance and corrective maintenance for BMS infrastructure and associate control components.
• Review Medium and High Risk Change, maintenance, break-fix works that related or interface with BMS and Control.
• Review and support Method of Procedure (MOP), Risk Assessment (RA), Statement of Work (SOW) and test documentation for activities involving BMS controllers, software, firmware, control logic, alarm configuration, communication interfaces and system integration.
• Witness, support functional testing, integrated systems testings, failover testing, post maintenance verification, Cx commissioning as required.
• Ensure the affected monitoring points, control sequences, alarms and system interfaces have been tested and restored to the approved operating condition before any activity ticket is closed.
• Ensure all BMS, Control Changes are authorized, traceable and supported by appropriate backups, configuration records, test result, rollback arrangements.
• Verify the final system configuration and operating documentation reflect the actual installed condition.

Commissioning and Operational Readiness

• Support the review of BMS design submissions, control narratives, points lists, graphics, alarm matrices, sequences of operation, network architecture and system integration requirements during construction, commissioning, expansion projects, retrofit project, customer fit-out projects.
