Automated GNSS Settlement Monitoring

Undisclosed location, USA
Project duration: 14 months
An industrial structure is being constructed on former farmland in the United States. The soft ground is being improved using wick drains and surcharge loading. To safely and accurately track consolidation, automated settlement monitoring with Locator One GNSS sensors was implemented.
Basetime Locator One units monitoring settlement on the Gorinchem–Waardenburg dike during reinforcement works.
Direct insight into settlement, enabling optimized planning, reduced project duration, and a measurable improvement in project outcomes.

Project Purpose

The objective was to precisely monitor consolidation during surcharge placement, avoid site disruptions, and provide the client with direct real-time access to settlement data to support efficient project management.

Implemented Solution

Geo-Instruments proposed replacing manual optical surveys with fully autonomous Locator One sensors. These were rapidly installed on the settlement plates, and the open terrain provided excellent GNSS reception. Each sensor transmitted measurements up to twelve times per day via cellular connection, including radar-based fill height readings. All data were directly integrated into the Apollo system through GeoCloud, providing continuous client insight.
