Bridge Monitoring with GNSS Locator One GNSS sensors can be installed quickly and are fully autonomous: no cables, no power supplies, no gateways, no protective housings, and no maintenance. Locator One GNSS sensors use signals from GNSS satellites to monitor displacements in 3D with an averaged precision of ±2mm horizontal and ±4 mm vertical. Locator…
Read MoreMonitoring Soil Consolidation with Locator One
Monitoring Settlement with Locator One The Project An industrial structure will be sited on land that was previously used for farming. The soft ground is undergoing consolidation with wickdrains and a surcharge to improve its bearing strength and stability. Monitoring Requirements The progress of consolidation will be monitored using settlement plates. Specifications require weekly surveys…
Read MoreMonitoring Water Quality
Monitoring Water Quality The Project GEO is monitoring a construction project adjacent to a waterway. The project required water quality monitoring as well as the standard geotechnical monitoring. Monitoring Requirements The water quality parameters included pressure, water temperature, dissolved oxygen, pH, conductivity, and turbidity. Measurements were to be obtained at 1 to 6 hour intervals.…
