• Bid bond required: No
• Mandatory site visit: Yes
• Local integrator required: No
• Construction beyond panels: No
• PLC details: PLCs/RTUs mentioned but brands/models not specified. The focus is on the air compressor component of the system.
• HMI details: HMI/SCADA mentioned but specific software not specified. The contractor must ensure the entire system is at 100% operational efficiency to pass the DEKRA inspection.
• Comms details: Network infrastructure mentioned but specific media/protocols not detailed. The focus is on the operational efficiency of the pressure tank system and air compressor components.
• Confirm PLC platform, firmware, programming environment, and whether standard libraries/naming conventions are required.
• Clarify communications path (licensed/unlicensed/cellular), polling rates, and any radio path study or coverage constraints.

Integration Checklist

• Confirm existing site inventory, I/O counts, and any required standards (tagging, alarms, naming).
• Request current drawings, network diagrams, and as-built documentation (or plan for discovery).
• Define acceptance testing: FAT/SAT steps, cutover plan, and rollback expectations.
• Confirm PLC platform, programming environment, licensing, and source code handoff requirements.
• Clarify communications path, latency constraints, polling rates, and any coverage/path study requirements.
• Define remote access method, auditing/log retention, and IT/OT segmentation boundaries.
