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, PDUsCooling 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.Deliverables
