VPI / CCTV / Crawler Services
The CCTV is an in-line crawler that packs a heavy punch when it comes to inspections of pipes (typically sewer and drain) 6” - 96” in diameter. A CCTV pipe inspection can give information as to what is happening in the utility line and is used to detect cracks, infractions, and other imperfections in the line.
With its 360˚ pan & tilt and zero-degree turning ability, the CCTV camera offers the maximum visibility and adaptability that is necessary for this line of work. For the best quality investigation, cameras are typically limited to bends between access points.
The CCTV pipe inspection camera has the capability to:
- Travel 1,000LF from its insertion point
- Track pipe grade
- Relay real time video back to a remote screen operated by our NASSCO certified project manager
- Measure defects and ovality within the pipe
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 project manager, and can be downloaded by the customer via USB or media network.
The in-line inspection crawler has a steerable 6-wheel drive, giving our project manager the agility to navigate past obstacles that may deter others. The CCTV inspection 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 are commonly found in sewers, drains and pipes. Our crawler also has onboard lasers that can be used to measure defects and ovality within the pipe. For lines 4” or smaller in diameter, a push camera is a smaller camera option which can be pushed through a line by hand.
Applications: (Pipes Greater than 6” Diameter)
1. Sewer Laterals - Inspection, Locating, Mapping
GPRS has the capability to video the interior of a sewer or water pipe for lateral inspections including interior pipe condition and locating the lateral lines at the surface. Ground Penetrating Radar Systems serves construction firms, consulting firms, environmental agencies, pipeline companies, and residential customers. Each site is unique and will work directly with the Project Manager performing the work at the site. These services are complimented by our in-house Deliverables Department, provided CAD files, Google overlays, GPS files, and maps/drawings/sketches.
2. Storm Drains - Inspection, Locating, Mapping
Storm drains are routinely inspected by Video Pipe Inspection crawler cameras for leaks and blockages. GPRS works on industrial, commercial, and residential projects contracted by engineers and contractors who are utilizing daily Video Pipe Inspection crawler camera services. Crawler Cameras (CCTV) are a key component in preventative maintenance as storm sewers can present many issues.
3. Sewer & Drain Depth Verification
GPRS uses a host of technologies that complement the VPI crawler camera. Ground Penetrating Radar Systems is contracted by excavating and boring companies to verify depths of sewer and water pipes prior to the construction or excavation process. The CCTV robotic crawler carries a locatable sonde that allows tracking at the surface that will gives the Project Manager approximate depths and location. Ground Penetrating Radar (GPR) is then used to more accurately pinpoint depths and locations. Learn more about the process at simspec.org.
4. Pre & Post Pipe Installation Inspections
It has become a common practice in the construction world to inspect newly constructed pipes to ensure correct installation. Many times shallow drain lines, sewers, or any plastic pipes can be crushed due to the heavy equipment traffic during construction. GPRS utilizes the crawler camera (CCTV) services to video the condition of these pipes in post construction.
5. Buried Manhole/Structures
Often, clients are aware of buried manholes/structures but do not know the exact location. GPRS utilizes the crawler camera and sonde to mark the exact location of the buried manholes/structures, while also offering detailed manhole inspections.
6. Cross Bore Inspections
GPRS has experience in pre and post cross bore pipe inspections using our crawler camera services with lateral launch (see lateral launch information). Increasingly more states are adopting this practice, and using the push camera as a method for video inspection both before and after the boring process.
7. NASSCO Pipe Inspection
All GPRS Project Managers are NASSCO (National Association of Sewer Service Companies) certified in video pipe inspection, lateral sewer inspection, and manhole inspections. GPRS offers NASSCO pipe inspections for pipes 6” & greater for the crawler camera services. Our NASSCO reports offer insight into defects found, photographs, and videos of each pipe segment.
