Retrofit Scope of Supply
Protocol Gateway Supply
BACnet/IP and Modbus TCP/RTU gateways for legacy system integration. Compatibility confirmed by site survey and point-list review.
DDC Controller Replacement
New open-protocol DDC controllers for HVAC, lighting, and energy monitoring. Sized and configured to the sequence of operations.
Graphics & Dashboards
Modern graphical operator interface with floor plans, trends, alarms, and energy dashboards. Web-based or dedicated workstation.
Sensor & Actuator Upgrade
Replacement of failed or incompatible sensors and actuators as required. Scope defined during site survey.
Alarm & Trending Setup
Alarm prioritisation, escalation routes, and historical trending configuration. Alarm log exported on request.
Commissioning & Handover
Full factory acceptance test (FAT), site acceptance test (SAT), O&M manual, as-built drawings, and point-list documentation.
What Is Conditional on Site Conditions or Third Parties
Integration is subject to documented protocol availability, controller licensing, gateway compatibility, point-list review, network access, and third-party approval.
Capability is subject to selected hardware, site conditions, design review, third-party interfaces, commissioning requirements, and applicable approvals.
Indicative energy outcomes depend on existing equipment condition, operating profile, control strategy, installation quality, available data, and commissioning validation.
Frequently Asked Questions
What is a BMS retrofit and when is it needed?
A BMS retrofit replaces or extends an existing building management system without replacing all mechanical equipment. It is needed when an older proprietary BMS lacks remote monitoring, when the graphics platform is obsolete, when the existing system cannot integrate new equipment, or when the building owner requires open-protocol connectivity for energy reporting.
Can you integrate with our existing Siemens, Honeywell, or Schneider BMS?
Integration is subject to documented protocol availability, controller licensing, gateway compatibility, point-list review, network access, and third-party approval. Intellicon carries out a protocol compatibility assessment during the site survey and confirms integration scope before any commitment.
Will existing mechanical equipment need to be changed?
In most retrofit projects, existing HVAC equipment remains in place. Intellicon replaces or adds field controllers, sensors, and actuators as required. Mechanical work — if needed — is scoped separately and carried out by an approved MEP contractor.
How long does a BMS retrofit take?
Duration depends on building size, number of points, and existing system complexity. A typical commercial retrofit ranges from 6 to 20 weeks from site survey to commissioning sign-off. A free preliminary assessment is available to estimate scope.
What documentation is produced at handover?
Intellicon provides a full O&M manual, as-built drawings, point-list documentation, sequence of operations, commissioning test certificates, and a software backup. All documentation is in English and formatted for UAE authority review.
