Case Studies
Digital Twin for MRT Station Construction — Singapore MOM SSSS Compliant
Verified outcomes from energy saving, industrial IIoT, digital twin, and broadcast infrastructure deployments across Singapore.
Client Context
A main contractor for a new MRT station construction project on the Thomson-East Coast Line extension required a Singapore MOM Smart Site Safety System (SSSS)-compliant digital safety management platform. The construction site involved 400+ workers across multiple levels of underground excavation and above-ground structural work, with complex daily workforce movements and high-risk zones requiring real-time monitoring.
Challenge
MOM SSSS compliance requires real-time worker position tracking, equipment proximity alerts, fall hazard zone monitoring, and automated compliance reporting — all delivered through a certified digital platform. The contractor had previously used a manual sign-in/sign-out system with no real-time visibility. They needed a system deployable within 4 weeks before a scheduled MOM safety audit.
LHS Electronics Solution
COSMOS Construction — SSSS-certified real-time digital twin of the entire construction site; 3D model imported from project BIM files
Positioning — hardware-free worker tracking integrated into COSMOS; workers carry standard smartphones with the Mapsted SDK; zero wearable deployment cost
TRB Gateways — site-wide sensor data aggregation: environmental sensors (gas, temperature), perimeter breach alerts, and equipment proximity triggers feeding into COSMOS
MACH Switches — ruggedised site network backbone providing connectivity for CCTV, gateways, and COSMOS server integration
Cat6A — site network cabling throughout temporary site offices and monitoring positions
Outcome
- MOM SSSS compliance achieved before scheduled audit — zero non-conformities identified
- Worker location accuracy: <2 metre in underground zones; GPS handoff at surface exits
- Automated daily compliance reporting to MOM format — eliminated 4 hours of manual reporting per day
- Two equipment proximity incidents detected and flagged before physical contact — preventing potential accidents
- Deployment completed in 3.5 weeks from site survey to live operation
