Retrofit and controls modernisation

Signs that an existing BMS requires modernisation

• Controllers or software no longer supported
• Recurring comfort complaints and call-backs
• No usable documentation or backups
• Inability to integrate new plant or metering
• Operators avoiding the front end entirely

Live-building upgrade constraints

Most upgrades happen around occupants and operating plant. The work has to be sequenced so the facility keeps running — temporary control, out-of-hours cutovers and clear fallback positions at each stage.

Existing-system audit

We survey the installed controllers, field devices, network and documentation, and establish what can be retained, what must be replaced and where the integration risks sit.

Phased migration planning

A staged plan defines the cutover sequence, temporary arrangements and acceptance criteria for each phase, so disruption is controlled and reversible.

Protocol and interface strategy

We confirm which existing interfaces can be reused, where open-protocol interfaces are available, and where gateways are required — documented as integration responsibilities before work begins.

Recommissioning and handover

Each migrated system is retested against its sequences, with updated documentation and operator briefing, so the building is left maintainable.
