CASE STUDY: BMS Field Services & Lifecycle Management
Category: BMS Field Services / Smart Building Operations
Client Type: Commercial Tower
Location: Dubai, UAE
The Challenge
Even the most advanced Building Management Systems (BMS) can suffer from “performance drift” over time. Our client was experiencing inconsistent climate control, frequent sensor failures, and rising energy costs due to unoptimized setpoints and lack of routine field calibration. Without expert intervention, the system was becoming a liability rather than an asset.
The GESS Solution
GESS provided a comprehensive BMS Field Services package designed to restore and enhance the system’s integrity. Our team of specialized field engineers conducted a deep-dive audit and implemented a recurring maintenance framework.
- Field Device Calibration: Precise calibration of temperature, humidity, and $CO_2$ sensors to ensure accurate data input for the controller.
- Actuator & Valve Testing: Hands-on inspection of dampers and valve actuators to prevent energy leakage and ensure mechanical reliability.
- Loop Tuning & Optimization: Fine-tuning of PID loops to eliminate hunting and reduce mechanical wear on fans and pumps.
- Proactive Fault Detection: Deployment of diagnostic tools to identify communication bus errors and ghost alarms before they caused system downtime.
Project Impact & Results
| Metric | Achievement |
| System Uptime | 99.9% through proactive field maintenance |
