Great Western Highway Upgrade Geotechnical Investigation, NSW, Australia

Australia’s longest road tunnel at 11kms long, this project is located near the Blue Mountains Region of NSW. When completed, the $2.5Billion project will form the main road corridor between Central Western NSW and the Sydney Region. Over 100 boreholes were drilled with some fitted with VWPs and others with monitoring wells, EWS Well-Caps and VWT devices were installed and are providing critical remote data over Iridium satellite connectivity for the geotechnical investigation.

Rail Culvert Flood Warning, Northern Territory, Australia

One of Australia's largest rail operators required flood warning on 100 low-lying culverts across it's network.  The compact Iridium EWS-EMT devices paired with hydrostatic level sensors allowed un-matched scalability and enabled this mega project to be completed within 8 weeks where alternative technology would have taken years. These sites will provide rail operators with remote data on culvert water levels with alert triggers for flood events from areas with zero cellular coverage.

Geotechnical Monitoring for Slope Stability, San Diego, CA, USA

EWS VWT Devices were deployed at a site near San Diego, California to log and transmit data from vibrating wire piezometers over the Iridium satellite network. The area had poor cellular coverage and data was critical for near real-time monitoring of soil pore pressure values that directly impacted the slope stability.
