Ground Penetrating Radar Scan performed at T4 LAX

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an electrical company in order to scan for reinforcing or conduits prior to core drilling for an office cubicle improvement. We found that the slab consisted of 6” on center wire mesh with an 8” thick metal decking slab. We marked all high spots of the metal decking with blue tape and all low spots with red tape; in this location we found no signs of conduits. We advised the customer to drill only on the high spots of the metal decking to avoid possible conduits that may be running on the low parts of the deck where it’s harder to see and also to reduce the thickness of the concrete that is to be cored to 4”. We performed this work during the night, while the office cubicles were unattended.

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.

Monitoring Wells – Las Vegas, NV

Monitoring wells are needed on a regular basis in order to test soil conditions below the surface. They can be necessary when selling property, when a hazardous material spill occurs, or for a number of different reasons. When installing or removing monitoring wells, it is important to know what utilities might be in the area. No matter what project is happening where digging is necessary, there are ways to keep yourself and your crew safer using underground utility location.

Monitoring Wells - Las Vegas, NV

Ground Penetrating Radar Systems (GPRS) was called recently to conduct underground utility locating around proposed monitoring wells that were to be removed near Phoenix, AZ.  Because these wells were installed by another company, the company that hired GPRS made the wise decision to have underground utility locating done prior to digging.

GPRS was able to identify utilities in the area where the digging was planned to occur. A 400 mHz antenna with the ground penetrating radar was used by GPRS to scan the areas as well as a Radio Detection wand which picks up most underground utilities with a current running through them.  All of the findings were clearly marked on the surface with spray paint and discussed with the customer. Whether working on removing monitoring wells, an older historic landmark, or a freshly built hospital and everything inbetween, Ground Penetrating Radar Systems can help.

GPRS is a private utility locator.  That means that GPRS can locate utilities where traditional “811” or Blue Stake services cannot go.  811 or Bluestake will only conduct underground utility locating on the public side of the respective utility’s meter and no futher.  GPRS can locate any and all utilties, whatever the need, wherever the location.

Prior to digging, saw cutting, core drilling, excavating or boring in Arizona, be safe and get as many questions answered as to what sub-surface obstructions are present.   This can include reinforcement or utilities within concrete or underground utilities.  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.

Ground Penetrating Radar Scan performed at Gas Facility

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an environmental company in order to scan for drains at a gas plant in Marina Del Rey. The purpose of the scan was for the environmental firm to evaluate the number of drains onsite and the sizes to then determine whether the facility needs to add or replace drains. Due to the heavy rainfall earlier this year, the current drains were not exceeding expectations of draining the rain water down the steep slopes to the street which caused several mud slides onsite. We were able to find most drains up to 4’ with GPR, and we also used our Duct hunter to run through deeper lines to then locate them with Radio Detection 7000+. All findings were marked on the surface with paint and flags.

Ground Penetrating Radar Scan performed at Parking Garage, Los Angeles, CA

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an engineering firm in order to scan for post tension cables on the third level of the parking structure. The purpose of the work was to repair post tension cables throughout all the levels of the structure due to many of the cables snapping or no longer sustained the proper amount of tension.  The client needed areas marked out prior to chipping through the 6” thick slab. We scanned (7) 10’x4’ areas on level E and marked all findings on the surface with spray paint. We marked all post tension cables with red paint, rebar was marked with blue paint and beams were marked with pink paint.

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.

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.
