Review system architecture, point lists, interface protocols

(BACnet, Modbus, SNMP, OPC, KNX, Lon Works, MQTT, etc.), IP planning, VLAN, redundancy, and cybersecurity schemes.

Construction Technical Management

Review contractor shop drawings, material and equipment submittals, RFIs, and technical clarifications. Supervise site installation quality, including cable trays, conduits, cable laying, termination, labeling, cabinets, equipment installation, grounding, concealed work acceptance, copper/fiber link testing, point-to-point checks, insulation, and loop checks. Coordinate interfaces with civil, mechanical, electrical, and fire protection disciplines.

Testing and Commissioning Support

Participate in ELV single-equipment tests, system integration, and integrated performance tests, including BMS/DCIM point-to-point verification, fire alarm interlocks, gas suppression interlocks, CCTV and access control tests, leakage detection, structured cabling certification, network connectivity and redundancy switching, and SCADA/DCIM integration. Review commissioning plans, scripts, and reports; support IST, Level 4/5 commissioning, and handover.

Vendor and Contractor Management
