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. 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.
5. 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.
6. 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.
Deliverables
- Control Philosophy Document (CPD)
- Functional Design Specification (FDS)
- Control System Architecture & Network Diagram
- FAT/SAT Test Protocols & Reports
- OT Security Policy for Automation Systems
- Standardized Tag List & Alarm Database
