The CCTV division brings a completely new technology to the GPRS family. This in-line crawler packs one heavy punch when it comes to inspections of pipes 6” – 96” in diameter. With its 360* pan & tilt and zero degree turning ability, it offers the maximum visibility and adaptability that is necessary for this line of work. It can travel 1,000LF from its insertion point and can track pipe grade, monitor temperature/pressure with its onboard sensors, and relays real time video back to a remote screen operated by our NASSCO certified technician. The crawler camera captures superior video resolution and can illuminate targets with bright LED lights or an auxiliary lamp for larger pipelines that requires more lighting. The video is carefully studied and recorded by our technician which can be downloaded by the customer via usb or media network.
The in-line crawler has a steerable 6-wheel drive giving our technician the agility to navigate past obstacles that may stop others. The crawler is able to switch out wheel types and has a detachable lift that allows it to handle any combination of pipe size (6”-96”), material, and condition. The overlapping 6-wheel drive makes it the best option for climbing over offsets and debris that we might find while exploring. Our crawler also has onboard lasers that can be used to measure defects and ovality within the pipe.
This Nationwide service comes with NASSCO certification and is available to anyone who requests it.

Dave Mulcahey is our lead project manager here at GPRS for our CCTV division. He is NASSCO certified and comes to us with over 6 years of experience using the in-line crawler. Dave is also a 3rd generation locator who began helping his father on locates at the young age of 12. After college, Dave started working at an underground locating manufacturing company where he was able to manufacture, use, and the sell the equipment. Soon Dave joined a company that was in charge of doing the actual locates and found his passion for the crawler systems. He then put his talents to use and started traveling the country to perform services. During this time, he enrolled into NASSCO certification classes to gain more knowledge on the sewer and storm line inspection world.
Dave is excited to join the GPRS family and is looking forward to providing the same great service throughout the country. This added value is tremendous for our customers and allows us to remain the Nation’s leader in subsurface investigations.
GPRS’ South Florida Office has been fortunate to partner with Suffolk-Yates on the Hollywood Hard Rock Casino Project in Hollywood, Florida. When locating at a facility that has developed and expanded over the years, there are always unknowns beneath the surface. Very few facilities are able to keep up as-built drawings with the speed of expansion and growth as they meet the demands of their clients. The Casino is no exception to that challenge. The difficulty of creating an accurate utility map for private facilities lies many times in the contractors updating existing maps with new installations. Communication is not always complete, and oftentimes new utilities are not added to existing maps or old utility maps are not merged with new, up-to-date as-built drawings. This can be a nightmare for contractors as they begin excavation and construction on existing facilities without the knowledge of what lies below the surface. GPRS contracted with Suffolk-Yates to assist in building a line-strike prevention process prior to excavation; the resulting process included a private utility locate utilizing GPR and a Radiodetection unit as well as CAD mapping services. This was determined to be the best route for safely and efficiently excavating on the site while mitigating the risk for damage of utilities or injuries.
Throughout this particular project, GPRS located utilities on the property prior to all excavation and demolition on site. Following our investigations, we were able to collect GPS data for all of our findings and upload those data points into a CAD file for the client on site. The results are an up-to-date drawing of existing utilities in the ground that can be distributed to the subcontractors completing the digging onsite as well as facility personnel for their records after the project and in the future when new excavation needs arise. The results of our investigations no longer need to disappear with the paint and flags onsite as time passes by, but can be introduced into a file allowing for long-term documentation of the items found beneath the surface, with their depth. In the images provided, you can see Project Manager Peterson Jean-Baptiste locating in an area where future excavation will occur. The known utilities in this area were two water lines, a gas line and comms/fiber (although the location of the fiber was unknown). In the first photo (above) you can see that approximately 10-15 utilities were located in this area in addition to the known utilities. The risk that was mitigated in this area by having a private locate ahead of time saved the client not only potential massive costs for damaged utilities but also in project delays and potential damage to existing casino utilities that might have shut down operations at the facility. Utilities identified in this area were water, gas, electrical conduit, lighting conduit, fiber, sanitary, storm sewer, unknown utilities and one buried manhole lid covered in the asphalt. The old adage goes, “an ounce of prevention is worth a pound of cure” and this certainly was the case for our clients on this project.
Ground Penetrating Radar Systems, Inc. of Phoenix, AZ. was contacted by a local residential plumbing contractor to lay out all of the Post Tension cables inside a bathroom prior to remodeling. The contractor was needing to cut the floor to move some of the plumbing pipes around for the install of a new handicap shower/ bath. GPRS is able to come into a project like this and mark the exact locations of each PT cable and mark them directly on the floor as shown in the picture below. We also give the depth for each of the cables so the contractor is able to chip around these without hitting them. It is always a good idea to get these cables marked out prior to any saw cutting or drilling to avoid damage and added cost to have the cables repaired.
Ground Penetrating Radar is ideal on a busy construction site as well as a place of occupancy. GPR does not require evacuation of the area as does traditional x-ray concrete imaging. GPR emits no radiation and is completely safe to be around. Traditional x-ray is mostly done after hours; GPR can be done during normal business hours. All data findings are marked directly on the surface at the customer’s request for the easiest interpretation of the scanning provided. With GPR, there is no wait for developing films as with traditional x-ray. Only one side of the slab is needed for scanning so time and resources are much more ideal for tight schedules of projects. Ground Penetrating Radar is the new way to x-ray!
Ground Penetrating Radar Systems, Inc. specializes in ground penetrating radar service as well as private utility locating. With that in mind, regarding the amount of experience and specialization of concrete imaging and utility locating as well as a nationwide network of technicians, GPRS, Inc. is unrivaled in the industry.
