Utilty Monitoring Point

Utility monitoring points (UMP) are used to monitor underground utilities for potential displacements caused by construction activities. Datasheet

Applications

  • Monitor displacements caused by excavating, dewatering, tunneling, trenching, and other construction activities.
  • Serve as automated heave-settlement points to monitor ground loss or heave in foundation soils.

Operation

A UMP consists of a rod within a riser pipe. The rod is in contact with the utility. The riser pipe allows the rod to follow any vertical movements of the utility. Displacements are detected by monitoring the top of the rod.

When frequent measurements are required, the UMP can be automated by fitting a survey prism to the top of the rod and monitoring its position with an AMTS. Multiple UMPs can be monitored this way with a single AMTS. When line-of-sight is not reliably available, the UMP can be fitted with a wireless displacement sensor.

The AMTS or displacement sensor relays
its measurements through the internet to a GeoCloud server. The server checks for alarm conditions and sends out alerts, if necessary.

Advantages

  • Low Profile: The UMP does not interfere with traffic or construction activities. It can be installed completely flush with roadways or under a low-profile, heavy-duty dome on construction sites.
  • Safe & Cost Effective: Automated monitoring eliminates the need and expense of survey crews and traffic control.
  • Timely Data: Alerts can be delivered to smartphones via GeoCloud, which also makes plots and data available.
