Technical Scope of Work
1. System Architecture & Design - Must
Define and document the overall control architecture , including :
PLC / DDC network hierarchy and supervisory levels.
OT LAN segmentation, VLAN design, and IP plan.
Redundancy and failover logic for automation systems.
Develop IO lists , control philosophy documents and functional design specifications (FDS) .
Coordinate between MEP consultants , controls contractors , and operations to align automation design.
2. Control System Development - Must
Author control sequence logic for :
Power systems : Need to have good understanding of the capacity framework and working design of UPS, LV / MV switchgear, gensets, fuel systems, PDUs
Cooling systems : Need to have good understanding of the capacity framework and working design of chillers, CRAHs, pumps, valves, cooling towers, heat exchangers.
Configure and validate PLCs, DDCs, and SCADA servers (Schneider / Siemens / Rockwell / Honeywell).
Standardize data points and naming conventions across all systems.
Implement interoperability via BACnet / IP, Modbus TCP / IP, OPC-UA , and MQTT brokers for telemetry aggregation.
3. Commissioning & Validation - Must
Develop FAT / SAT scripts for validation of control logic, redundancy, and failover scenarios.
Execute alarm and trend validation to ensure full functional coverage.
Oversee integration testing with DCIM , AIops , or energy optimization platforms.
4. OT & Cybersecurity Governance - Great to Have
Define the OT framework for automation systems, including :
Network segregation between IT and OT.
Firewall and DMZ policy enforcement.
Patch management and backup strategy for controllers and servers.
Align systems to IEC 62443 or equivalent cybersecurity compliance framework.
Maintain system access logs , firmware inventories, and security posture reports.
5. Operations Enablement - Must
Create O&M procedures for BMS / SCADA systems including :
Change management and version control.
Alarm rationalization and escalation protocols.
Data historian configuration and retention policies.
Develop automation analytics dashboards to track PUE, thermal KPIs, and predictive maintenance metrics.
6. Continuous Optimization - Must
Collaborate with design and operations teams to :
Tune PID loops and optimize control setpoints.
Integrate AI models for predictive control.
Support digital twin deployment and data validation.
