• 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 project involves HVAC controls, which typically use PLCs or RTUs, but the title does not specify brands or models.
• HMI details: HMI/SCADA mentioned but specific software not specified. HVAC systems often integrate with HMI/SCADA systems for monitoring and control, but the title does not specify the software.
• Comms details: Network infrastructure mentioned but specific media/protocols not detailed. Communication between HVAC equipment and a central control system is implied, but the title doesn't specify the communication protocols or media used.

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.
