How Does C-N-I Locates Detect Communications Underground?

1. Electromagnetic Equipment (Metallic Line Detection) 

Our experts utilize electromagnetic (EM) equipment to detect metallic/conductible utilities buried underground.  EM transmitters emit an electromagnetic radiofrequency field around utilities via direct connection (clipping to the utility), signal clamp (clamping the utility), or through induction until the signal attenuates or there is a break in continuity. These electromagnetic radiofrequency fields can be detected by an EM receiver, allowing it to trace the path and locate the underground line. Furthermore, the strength of the current and the corresponding signal received by the locator help us find the location, depth, and direction of the buried communication lines and other utilities. Electromagnetic receivers also have the ability to passively sweep for unknown live conductors that emit a 60/50 Hz power signal, radio signal, CATV signal, or CPS signal.

2. Traceable Rod/Sonde or Push Video Camera (Nonmetallic Pipe Detection & Video Camera Pipe Inspections) 

For nonmetallic communication lines, such as fiber optic cables or empty plastic conduits, C-N-I locates experts employ various techniques. One approach involves using a traceable rod or sonde. A sonde is a small, battery-powered transmitter that is attached to a flexible rod that can be pushed into a nonmetallic pipe. The sonde emits a continuous radio frequency signal that can be detected by an electromagnetic radio frequency receiver. Our technicians can follow the path of the signal transmitted by our traceable rod and sonde, which help determine the estimated depth, location, and end of pipes (or blockages).

Another technique for nonmetallic pipes is the utilization of a push video camera. These cameras are designed to be inserted into pipes and can capture real-time video footage of the pipe’s interior. By pushing the camera through the pipe, operators can visually inspect the condition of the pipe, identify any blockages, or damage, and determine the path of the communication line. C-N-I Locates LTD is Oregon and Washington States leader for locating Communication, Tv, Phone, Fiber Optic, Satellite, and any other type of utilities.

3. Ground Penetrating Radar (GPR)

GPR is commonly used to locate underground communication lines that need accurate depth assessments, aren’t accessible, are non-conductible, etc. GPR works by emitting electromagnetic pulses into the ground and measuring all the reflected signals. Further, the radar pulses are able to penetrate the soil and other materials, and when they encounter changes in dielectrics (e.g., various subsurface layers, utilities, or objects) they reflect back to the unit.

By analyzing the characteristics of the reflected signals, operators can identify the location and estimated depth of buried communication lines and other utilities.

GPR’s effectiveness varies depending on a few factors, such as soil composition, depth of the utility, size of the utility, material the utility is made out of, underground obstructions, and more. Skilled operators with proper training, and knowledge of the area are crucial to ensure accurate and reliable results. 

CNI technicians also have the ability to provide underground utility mapping services on all outdoor projects (if requested by the client).

Why Is It Important to Locate Communications Before Performing Subsurface Work?

  • Safety Precautions for Underground Communications 

It is important to know the location of all the communications and utilities in a work area to help ensure the integrity of utility infrastructure, safety of workers/nearby residents, and that there are no project delays or costly damages, etc. When undertaking excavation or construction work, there is a risk of accidentally damaging utilities such as electrical cables, water mains, gas pipelines, telecommunication lines, etc. Underground utilities can pose significant dangers if mishandled. For instance, severing a high-pressure gas line can result in explosions or fires, while cutting an electrical cable can lead to electrocution hazards. By accurately identifying and being aware of the precise locations of these utilities, workers can take necessary precautions to avoid unintentional damage.

  • Time Efficiency in Subsurface Work 

If utility detection services are not provided before subsurface work has been performed, damage to utilities can occur. Accidentally damaging underground communications can result in costly repairs, project delays, a damaged reputation, and legal liabilities. Repairing or replacing damaged utility lines can be time-consuming and expensive, potentially disrupting ongoing operations or causing significant delays in construction projects. By locating and marking communications beforehand, workers can plan their excavation or construction activities accordingly, minimizing the risk of damage and avoiding costly setbacks.

  • Regulatory Compliance 

Many States, Cities, and jurisdictions have regulations and laws in place that require the identification and protection of underground utilities. Failing to comply with these regulations can result in legal consequences and penalties. By locating and respecting communication utilities, construction and excavation companies demonstrate their commitment to adhering to safety and compliance standards, reducing the likelihood of legal issues and associated costs.

  • Minimizing Service Disruptions 

Accidental damage to underground utilities can result in disruptions to vital utilities like electricity, gas, water, telecommunications, etc. This inconvenience affects businesses, residents, and public services reliant on these utilities. By utilizing a locating service to accurately identify communication lines and other utilities, construction and excavation teams can take necessary precautions, preventing harm to these crucial services. This proactive approach minimizes disruptions and ensures the uninterrupted provision of essential services.

What Can Happen If a Communication Line Is Damaged While Performing Subsurface Work?

When performing subsurface work, the consequences of damaging a communication line can be wide-ranging. First and foremost, service disruptions are a common outcome. Damaging a communication line can result in a loss of connectivity for telecommunication services such as telephone, internet, and data transmission. Furthermore, all these disruptions can have far-reaching effects on individuals, businesses, and other public services that rely on these communication channels.

Financial losses are another consequence that can happen because of damaged communication lines. Companies dependent on uninterrupted communication may experience lesser sales, deal with missed opportunities, and decreased productivity. Repairing the damaged line and restoring services can also lead to major expenses, further impacting the financial aspects of an ongoing construction project.

The safety hazards associated with damaged communication lines should not be overlooked. Severed communication cables, for example, pose an electrocution risk to workers and nearby pedestrians. Additionally, damaged communications can disrupt the ability to contact emergency providers (e.g., police, fire department, ambulance, etc.) for workers and nearby residents.

From a legal standpoint, damaging communication lines can result in legal consequences. Many jurisdictions have regulations that require the proper identification and protection of underground utilities. Failure to comply with these regulations can lead to fines, penalties, and legal liabilities for the responsible party.

Project delays are a common outcome of damaging communication lines. Construction or excavation work may need to be halted until the damaged line is repaired or replaced, leading to extended project timelines and potential cost overruns.

Lastly, damaging communication lines inconveniences the public in Washington and Oregon State. If essential services like emergency communication or public transportation systems are affected, it can cause confusion, frustration, and a loss of trust in the responsible party.

To avoid all these negative and unexpected consequences, it is vital to take proactive measures and connect with C-N-I Locates underground utility locating services to identify and protect communication lines before commencing subsurface work.
