Utility Monitoring Point
Utility monitoring points (UMP) are used to monitor underground utilities for potential displacements caused by construction activities. Datasheet
UMP 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
Vertical displacements of the utility are transmitted to the surface by means of a rod that is anchored near or directly to the utility. Displacements are detected by monitoring the top of the rod.
Monitoring Options
Optical UMP: A prism is fitted to the top of the riser rod, which is installed within a PVC sleeve to allow free movement. An AMTS monitors the elevation of the prism. One AMTS system can monitor multiple UMPs.
Digital UMP: A single-point rod extensometer is anchored close to the utility. Movement of the utility is detected by a displacement sensor in the extensometer head. A wireless logger transmits the readings to a gateway. This option is especially useful if consistent line-of-sight is not available.
Manual Verification: An optional manual-read feature is available with the AMTS version, allowing verification readings with a depth gauge.
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: Measurements are relayed to a GeoCloud server that checks for alarm conditions and sends alerts to desktop PCs and smartphones.
