Pipe and Cable Electromagnetic Inductive Locators
UMS’s geophysical toolbox includes the new Optimal Ranging SPAR 300© electromagnetic induction system which is fully integrated with the Trimble Access surveying environment and operates seamlessly with Trimble GNSS receivers or with Trimble Total Stations. When integrated with Trimble surveying equipment the SPAR 300© derives 3D alignment data (elevation tied to project control) for conductive utilities, including appropriate error metadata. UMS usage of the SPAR 300 over past 3 years has allowed development of procedures and experience required to provide highly valuable, continuous 3D profile data at a fraction of the cost of discrete vacuum excavated test holes.
UMS’s geophysical toolbox also includes conventional pipe and cable electromagnetic inductive locators such as the RD8000, RD500, Ditch Witch Subsite950, and Rycom. UMS ground penetrating radar devices include the Noggin Plus 250 MHz Smartcart GPR, the Mala GeoScience 350 MHz GPR, and the SIR 3000 with high and intermediate frequency antennas.
Other Geophysical Electromagnetic Induction and Magnetic Gradiometer Survey Equipment
As projects require, UMS utilizes a variety of tools, from simple magnetic detectors to the sophisticated Geonics EM-61 and Geometrics G-858 Magnetic Gradiometer.
Trimble R8 GNSS Systems – base and rover for RTK GPS surveying, TSC3 Controller
DJI A2 Aerial imagery/video platform
Current software includes: Trimble Geomatics Office, Bentley : Open Roads/Power GEOpak/ SUE / SUDA, Golden SURFER, ESRI ArcGIS, EKKO_Mapper Version 3.
Through subcontracting agreements with local vacuum excavation specialists; UMS utilizes various types of vacuum excavation equipment capable high-pressure air or water methods to expand and break up soils adjacent to a given utility and a powerful vacuum to remove these spoils. The use of the high-pressure air is totally non-destructive and will not damage even the most vulnerable utilities. All of this equipment is truck/trailer mounted, which allows easy and safe access to most locations. Based on project requirements and location, UMS will utilize the appropriate sized equipment to complete the project in the most efficient manner possible. When high pressure water applications are required in cold weather conditions, measures will be taken to ensure the necessary water supply remains fluid; allowing for year round vacuum excavation capabilities.
Seismic Refraction and Engineering Geophysical Surveys
In addition to utility investigations, UMS also performs a variety of engineering geophysical surveys to investigate bedrock, groundwater, and other subsurface conditions.
