Subsurface Utility Mapping and Locating tools provides construction and geotechnical professionals the required information of the buried utilities, the location, depth and status for project design, maintenance, renovation, demolition, drilling, coring, trenching and excavation activities usually carried out in the construction site. The use of non-destructive techniques such as Electromagnetic Induction Locates, GPR and Time Domain Electromagnetics for Quality Level B, C and D in Utility Mapping applications guarantees several benefits to the industry including reducing project cost due to utility damages, construction delays and increases the project and public safety in general. For an efficient identification, mapping, presentation of utility information and completion of Subsurface Utility projects, Geophysics HM Ltd adheres and follows the Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data ( ASCE Standard 38-02) and the CSA Standard S250 released in 2011 by the Canadian Standards Association (CSA).
Geophysics HM Ltd offers private utility locates, marking and CAD services using advanced and current instrumentation and highly precisesurvey mapping systems. ThevLoc3-Proutility locator introduces new innovative tools for locating buried utilities assuring damage prevention while gathering information for analysis. With two sets of screened 3D antennas signal distortion is easily detected and displayed on the bright full color display. Along with classic locate screens the vLoc3 series locators offer new locate perspective screens of Vector Locate for fully automatic non-walk over locating, Transverse Graph showing both peak and null simultaneously providing immediate measurement of signal distortion, Plan View showing the relative orientation of the cable at any angle, and a new graphical Sonde screen with guidance arrows leading to the sonde location even when it is vertical.
The highly user configurable vLoc3 series contains eight passive locate modes, fault-find mode, SD (showing direction of outgoing current), and a range of configurable frequencies from 98Hz to 200 kHz. Audio and mechanical vibration alerts can also be configured by the user providing warnings for shallow depth, overload, overhead cables, and excessive swinging. Plug-in-play options for the receiver include optional Bluetooth module useable with external GPS devices and EMS foot to locate buried markers (Vivax Metrotech, 2021).
