Construction Site Challenges and TRAILS Implementation

Indoor Positioning System for Enhanced Tunnel Construction Safety

In tunnel construction sites, excavation and concrete lining work occur simultaneously, with 25-ton dump trucks and concrete mixer trucks operating in confined spaces. Visual monitoring alone is insufficient for maintaining safe distances between vehicles, forcing workers to rely on horns for position confirmation. The environment presents unique challenges: 100% humidity and the need to continuously install new positioning beacons as excavation progresses. Alternative solutions (cameras, SLAM, geomagnetic sensors) prove impractical under these harsh conditions.

Construction site overview

Current solutions cannot effectively track worker and vehicle positions to address::

  • 1. Safety Enhancement in Tunnels - Need to prevent collisions between heavy machinery/dump trucks and workers while ensuring comprehensive safety management.
  • 2. Reducing Vehicle Standby Time per Excavation Cycle - Goal to optimize vehicle operations and improve productivity.
  • 3. Visualizing Construction Progress for Enhanced Productivity - Need to efficiently record and report when and where each worker performs their tasks.

What TRAILS Can Do

TRAILS is a next-generation location intelligence system that requires no infrastructure installation and enables:

Worker Safety Through Location Management

Using smartphones and smartwatches, TRAILS sends real-time alerts when vehicles approach workers. The system continuously monitors the relative positions of workers and vehicles in tunnels to prevent accidents.

Efficient Vehicle Navigation in Tunnels

Through predictive analytics, TRAILS optimizes vehicle movement. This ensures smooth traffic flow while maintaining safety standards.

Automated Work Documentation

The system automatically records worker locations and activities, streamlining daily report creation. This significantly reduces paperwork while maintaining accurate records.
