The challenge
Complex constraints.Real-world pressure.
Before architecture and implementation, we mapped every operational blocker and business risk. These were the core constraints shaping the entire solution design.

What we built
A system built for the problem, not off the shelf.
We built a maintenance management platform with an IoT integration layer for connected lift controllers. For units without IoT capability, a simple QR scan at the lift machine room triggered the digital service record — eliminating paper job cards entirely.
The scheduling engine auto-generated preventive maintenance schedules for all 1,200 units based on AMC terms and last-service date. Technician route optimisation clustered nearby jobs to minimise travel time. Clients received automated visit reminders and confirmation SMSes.
For IoT-enabled units, the fault monitoring module ingested controller data in real time. Anomaly patterns triggered predictive alerts before faults became breakdowns — allowing the dispatch team to route a technician proactively.
Capabilities delivered
Every feature with a reason.
01
Automated PM scheduling
Maintenance schedules auto-generated for all units based on AMC terms. Technician assignment optimised by geography and workload.
02
IoT fault monitoring
Real-time fault feed from connected lift controllers. Anomaly patterns trigger predictive maintenance alerts before breakdowns.
03
QR-scan digital job cards
QR code at machine room triggers digital job card. All service actions logged with technician ID, timestamp, and parts used.
04
SLA tracking & breach alerts
Response and resolution SLAs tracked per contract tier. Breach imminent alerts route to duty manager automatically.
05
Customer portal & history
Building managers access their lift service history, upcoming PM schedule, and current active calls through a self-service portal.
06
Technician performance analytics
Jobs per day, first-fix rate, travel time, and customer satisfaction score per technician. Used for incentive management.
