City Street Utility Locating After BC One Call Setup - Vancouver, British Columbia

GPRS Enterprises Inc. of British Columbia was called out to conduct a a utility location scan in an alleyway prior to trenching in order to install new gas feeds to multiple businesses. The alley way that was scanned contained all of the utility hookups for the businesses that were being serviced, including storm sewer, sanitary sewer, communication/fiber optic lines, power/electric, and water/hydro hookups. We began by visually inspecting the alley, looking for any visible conduits, gas meters, manholes, and visible utility evidence. All manholes were accessed, in order to get depths and to fish a traceable sonde and sewer cable down each clay pipe. Ground penetrating radar (GPR) was then used to find any other utilities without a passive charge. Electromagnetic detection, or radio detection (RD) was used to tone onto any visible metal pipes, or conduits in the area, and was also used to passively sweep for any charged utilities. The photo to the right shows a sample area of some of the marked utilities on site.

The contractor that hired GPRS was planning on removing the sidewalk in order to widen the street in this area, so it was very critical that these previously unidentified utilities were accurately located. Private utility locating services with ground penetrating radar coupled with BC one call and city plans insures that utilities are accurately found, and eliminates any unknowns on your project.

The utility map above is an example of a simple red line drawing that was provided to the contractor after the marking of utilities on site was completed. GPRS can provide output maps ranging from something similar to that which is shown above, to Google Earth satellite image overlays, AutoCAD drawings, and simple hand sketches in the field. All of these different mapping options are tailored directly to the parameters of the project, and the needs of the client. GPRS is also happy to setup BC one call appointments prior to showing up on site, in order to provide a fully inclusive service and make sure nothing is left to chance regarding unknown utilities.
