Ground Penetrating Radar Scan Performed in Somis, CA

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an engineering firm in order to scan for rebar. The scope of work included scanning an approximate 10’x12’ area on a concrete pad prior to anchoring 3’ for a new satellite that would be replacing an older one that was already removed. Within the area scanned, (3) large base plates are proposed to hold down the new satellite.  We found that the rebar was approximately 12” on center and in some areas it was 6” on center. In addition to the rebar scanning, we also scanned for the existing conduits where the new data and power are proposed to be. We traced on to existing ground wires and cables in the conduits to then mark out the conduits using Radio Detection.

GPR scanning is a great tool to use for post tension cables, rebar, and conduits; it can also be used to scan for underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs projects in cities like; Ventura, Santa Barbara, Thousand Oaks, San Luis Obispo, Bakersfield, Lancaster and the greater Los Angeles area.

Ground Penetrating Radar Scan performed at Cedars-Sinai Medical Center, Los Angeles, CA

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by a general contractor in order to scan for reinforcing prior to core drilling in multiple areas. We scanned (3) different slabs that consisted of a 12” thick deck with rebar and post tension, a 6” deck with 12” on center rebar, and a 7”-8” deck with rebar and post tension. The contractor had asked us to scan large areas from 12”x12” areas to 5’x5’ areas for multiple proposed core drill and walker ducts. We marked all reinforcing findings with a black sharpie, and all beams were marked with red keel. We scanned approximately 7 sections throughout 2 floors and were finished within 2 hours, which gave the contractor enough time to lay out the cores and core drill that same morning.

Ground Penetrating Radar Scan Performed in Mojave, CA

Ground Penetrating Radar Scan performed in Mojave, CA Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an energy company in order to scan for utilities prior to mobilizing a crane. We were asked to scan an approximate area of 500’x300’ on an existing wind farm; the area we scanned was for a large crane that was to be stationed there. We first scanned the area using Radio Detection and found a high voltage line running parallel to a dirt road. We then used GPR and were able to confirm a depth on the line; the depth was 4’. Due to the wet conditions of the area scanned, we marked the finding with flags and pins.  No other utilities were found onsite.

Concrete Scanning & Utility Locating at Major Hotel on the Las Vegas Strip

On November 3rd, 2016, the Las Vegas community and hotel community in general learned a very valuable lesson. That morning is when a contractor who was saw cutting in a basement area at a hotel on the Las Vegas Strip, cut through the main power line, completely shutting down the power to the entire building. It would take about 20 hours before the power could be fully restored. Not only did the hotel lose money by needing to stop operations of everything that day at the facility, but they also had to provide housing for the guests staying in their hotel that night. In an effort to keep these guests as customers, they also offered two free nights at their hotel in the future. Had the contractor invested in utility locating and concrete scanning prior to the saw cutting, this whole ordeal could have been avoided.

Ground Penetrating Radar Systems was called recently to scan the basement area at another of the major hotels on the strip. The scanning done by GPRS allowed the customer to confidently dig without running into any power lines, while also missing what appeared to be post tension cables in the slab. GPRS used a radio detection wand along with  400 MHz & 1600 MHz ground penetrating radar antennas to scan the areas. All of the findings were clearly marked on the surface with blue tape and discussed with the customer before digging began. Whether working on an older historic landmark, or a freshly built hospital and everything inbetween, Ground Penetrating Radar Systems can help.

Prior to saw cutting, core drilling, excavating or boring in the Las Vegas and Southern Nevada areas, be safe & get as many questions answered as possible as to what sub-surface obstructions are present. Pretty much, if you have questions about what lies beneath whatever surface you’re working on, GPRS should be able to give you a much clearer picture as to what you are dealing with. Typically able to arrive on site to begin scanning within 1-2 days, GPRS will take care of your project in a timely, safe, and accurate manner. Contact the Las Vegas GPRS Project Manager, Andrew Yates, at 702-573-9228 or andrew.yates@gp-radar.com.

GPRS Helps Boats Safely Enter Harbor in Pago Pago, American Samoa

Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by a well-known general contractor based in Hawaii, as well as many of the US territories, to locate the structural steel in four concrete pillars. These pillars were designed to hold a large tower that housed a light that when lined up with another lighted tower on the mountain side, would guide boats safely into the harbor and miss the shallow reef in Pago Pago, American Samoa.  These types of lights are able to be seen for miles out in the sea when in use.  Because of the light needing to line up with the light on the tower on the mountain, it was critical that all structural steel was located so the tower could be engineered properly, allowing them to get the placement within 3cm of the original light. The contractor was on an extremely tight schedule due to the sensitive nature of the tower and safety for all those traveling in and out of the harbor.  The scanning was completed on time for the tower to be constructed and in place in the time required by the large, international organization that requested the work.

Ground penetrating radar is a great tool to scan areas of post-tensioned cables, rebar, and conduits, including PVC pipes. Ground penetrating Radar can also be used for locating underground utilities such as water, gas, electrical, communication, sewer, underground storage tanks and associated piping, and other objects prior to digging or excavating. Please contact Ground Penetrating Radar Systems – GPRS to learn how we can assist with your next project. Ground Penetrating Radar Systems has performed countless jobs like this throughout California and Nevada and also services the entire United States.
