CASE STUDY / Healthcare
Beijing Large General Hospital
PROJECT OVERVIEW
Control relationships organized around real building use.
This hospital campus supports outpatient, clinical, inpatient and facilities operations that continue across the day. Its BMS exceeds 10,000 I/O points and covers HVAC, ventilation, central plants, pumps, valves, terminal equipment, several controller generations, alarms, trends and central supervision. The task was to coordinate a system that had evolved over time without interrupting essential operation.
SYSTEM SCOPE
Building automation coverage
HVAC, ventilation and central plant systems
pumps, valves and terminal equipment across the campus
multiple controller generations, alarms, trends and central supervision
KIMMA SCOPE
Turning system scope into equipment, logic and commissioning.
On this project, Kimma handled the BMS scope around staged integration and long-term interoperability, integrating multiple controller generations, coordinating communications and central-platform access, and supporting commissioning. Controllers, networks and points were checked first; platform connections and feedback were then verified by area, with essential local control retained.
DELIVERY CHALLENGE
Site conditions shaped the delivery path.
Network segmentation and several generations of controllers made a single cutover impractical. Communications capability, point meaning and program status required separate verification, while each phase had to protect areas still in operation. Central supervision also had to preserve necessary local control.
PROJECT HIGHLIGHT
Complex system relationships made clear and maintainable.
The project established a workable path for long-term interoperability across controller generations and a complex campus network. Operators gained a consolidated view of status, alarms and trends while necessary local control retained its operating foundation. The distinctive value lies in staged system recovery rather than a disruptive one-time replacement.
