Southern Washington Aerial Drone Imagery Services

Utilizing state-of-the-art equipment, which includes the latest in drone equipment, one acquires high-quality, excellent definition and ground markings, as well as real site conditions during utility locating services. Switching to the project location, we furnish our clients with an updated outlook of their project area by employing Orthomosaic Photogrammetry. Since C-N-I Locates Ltd is one of the leaders in innovation, it offers you three unique services of aerial drone imaging that will suit your needs as a client. We will be glad to do away with the necessity of the conventional map or satellite image, hence ensuring efficiency and accuracy in every project.

Aerial Drone Photography: Aerial photography as a service employs modern-day unmanned aerial systems technology that takes still images and videos. This creativity also comes in handy once our utility detection service for the project is done; clients have aerial photos of the site immediately. Depending on the specifics of the project, you may be able to evaluate the site conditions as it is facilitated by this modern and efficient way of project recording.

Orthomosaic Photogrammetry: It creates a holistic view or a map of a specific segment of the earth using our drone technology, which accurately merges all the frames or photographs so that there are minimal distortions. This special service provides useful data as to the locations of the utilities, the depth evaluations, and the limitations, as well as the overall site condition during the flight. Unlike previously inadequate and poor-quality Google satellite maps, the result is an improved and up-to-date aerial picture overlay on an aerial overview map.

3D photogrammetry: This method involves taking data from items in the real world; after stripping the two-dimensional and three-dimensional data from an image, one builds a three-dimensional model by imposing pictures of the structure, item, landscape, etc. This tool is useful if one wishes to have a real visual copy of their property or if Google Earth has no three-dimensional picture of this property, among other reasons.

Electrical Ground Fault Locating Services in Southern Washington

If electricity directs its way to the ground unconventionally with no impedance and restrictions, then it is called a ground fault. This leads to the increase of the flow of charge at a very fast rate. If the cable or wire is directly buried or not in a conduit, the probability of a ground fault rises. The first thing you should do is inform C-N-I Locates Ltd of the defect with an underground cable or wire. Then, we can react accordingly. In general, we provide our fault-finding within 24 hours’ notice, Monday through Friday. We operate across the entire state of Washington, and our field offices are in Tacoma, Seattle, Renton, and Everett.

C-N-I Locates Ltd was established in 2001 and has been the pioneer organization as far as reliable services are concerned.

C-N-I Locates Ltd.’s ground penetrating radar antennas are a non-destructive method for locating hidden metallic and non-metallic items, objects, or utilities. While it is true that metals such as rebar or metallic objects provide the best visuals due to the high contrast in dielectrics from the materials around them, GPR can identify a number of other materials beneath the surface. This commitment to safety is adhered to by the utilization of high-frequency and low-frequency antennas, which do not emit any type of hazardous radiation or by-product. When looking for ground-penetrating radar services that provide deep, accurate results while at the same time maintaining the safety of the facility and personnel involved, C-N-I Locates Ltd is the way to go.

Leak Detection Services in Southern Washington

C-N-I Locates Ltd is a leading provider of expert leak detection services in Washington with easily accessible field offices in Everett, Washington, Renton, Washington, Seattle, Washington, or Tacoma, Washington. To identify an accurate location of a water leak highly trained employees of our company use such sophisticated techniques as tracer gas and improved acoustic amplification tools.

Non-conductible plastic water services may be encountered in buildings or homes constructed after the year 1969. There exists a requirement to use unique equipment in the detection of leaks in plastic pipelines for water, and our plastic water detection services are crucial in identifying the areas where the leakage observations have been made. A new ‘steel’ fish tape needs to be inserted into the water line so that the correct position for the pipe is given, especially when the plastic pipe cannot be tracked using Plastic Pipe detection and Ground Penetrating Radar methods. Our specialists are able to determine the inserted pipe by using receivers that receive signals that are emitted through steel fish tapes using electromagnetic transmitters.

Although C-N-I Locates Ltd makes an effort to offer thorough leak detection services, one ought to observe the limitations of a site. Some limitations that could possibly prevent the identification of leaks are not drilling test holes, no access to the utilities, backflow preventers, frost-free hose bibs, landscape matting, noise in the working area, obstacles, path of least resistance, plastic pipes, slope, type of soil, type of surface, unknown branching pipes, vapor barrier among others. When any of these restrictions arise, we promptly inform the customer about them so that they can determine the next course of action. For complete water leak detection services to be provided, there might be the need to re-visit after addressing the constraints. To receive detailed and effective leak detection that is properly adapted for each site’s specific challenges, always turn to C-N-I Locates Ltd.

Magnetic Detection Services in Southern Washington

To accurately locate ferrous metals, a specific technique of detection is used known as Magnetic Detection. These metals are classified based on the magnetic properties and iron content that is present within the material. The highlighted method proves to be very useful while searching for cast-iron pipes that have been covered, catch basins, fire-aids and hydrants, oil storage tanks, PK nails, road culverts, septic tank handles, steel drums, survey marks, valve and curb boxes, well casings, and many other objects. In the entire state of Washington, C-N-I Locates Ltd is one of the leading professional magnetic and metal detecting service companies. The committed field offices to ensure adequate coverage are situated in either Seattle, Tacoma, Everett, or Renton.

Metallic Pipe Detection Services in Southern Washington

Having field offices in Renton, Seattle, Everett, & Tacoma, C-N-I Locates Ltd is the company to contact when you are in need of excellent metallic line detection services. Known as metallic line detection or electromagnetic detection, it is the procedure of thorough screening for different conductible metallic utilities like power, phone, TV, and so on – including gases, water, lighting, and irrigation control lines. An electromagnetic transmitter and receiver are employed by our expert personnel to ensure precise and efficient detection is achieved.

There are three active techniques that are employed at C-N-I Locates Ltd for the purpose of locating metallic and conductible utilities. It is for this reason that methodologies employed in our metallic line detection services provide comprehensive and accurate outcomes. You can always trust us to meet your specific needs and deliver your project by employing contemporary tools and expertise.

Clipping Straight to the Utility (Direct Connection): This method is performed by connecting the clip directly where the pipe is located because this will ensure a good signal on the utility. It is recommended that bonds connected to the utility should be undone, especially where the utility is attached to other utility ground wires, as this may limit our professional’s ability to provide accurate services. This increases the total efficiency of the detecting operation through fewer signal interferences that provide a more exact signal.

Clamping the Utility (Signal Clamp): If our specialists cannot clip directly to the utility, they can determine the location of the utility by clamping it from a certain point. This clamping technique creates a good signal, and it is beneficial for detecting cables, conduits, power risers, communication drops, wires, and other associated items. All our team’s flexible approaches ensure accurate identification even if direct access may not be possible.

Inducing the Utility (Induction): In the final method, our specialists will use an electromagnetic transmitter to induce the utility if clipping onto it or clamping directly is unfeasible. Electromagnetic induction sends an electromagnetic signal into the earth via our electromagnetic transmitters. Despite beliefs that inducing is viewed as the least precise active locating technique, it transpires to be a practical solution when other techniques cannot be used to locate utilities. This method has become popular, especially when conducting a search in a certain work area for utilities that are unknown to the researcher.

Some passive methods are used by C-N-I Locates Ltd alongside active methods to help locate metallic and conductible utilities. Some of the methodologies that have set a pace for our devotion to ensuring that we deliver steadfast utility detection services aligned to the demands of each project include.

CPS: identifies a broad range of cathodic protection signals used in pipeline corrosion control.

CATV: Provides accurate identification of cable TV signals via most subterranean television wires.

Power: Accurately detects the presence of 50Hz–60Hz signals across most hidden electrical cables.

Radio: Accurately detects re-radiated radio signals on a wide range of submerged communication wires.

Non-Metallic Pipe Detection Services in Southern Washington

Recognizing utilities such as fiber optic conduits, drains, empty races, plastic water, sewage lines, etc., is referred to as non-metallic line detection. The principle of this procedure involves the use of electromagnetic transmitters and receivers paired with insertion equipment such as flex rods, flexi traces, fish tapes, tracer wires, and sondes. With the use of our state-of-the-art equipment, we provide accurate and reliable locates. The identification of non-metallic lines is crucial since the utilities are not inherently conductive and cannot be located using traditional metallic line detection methods.

Private and Public Utility Locate Services in Southern Washington

CNI Locates offers a plethora of utility detection and inspection services in Washington State, among them being Aerial Drone Imagery, Design Survey Locating, Electrical Fault Detection, Ground Penetrating Radar, Leak Detection, Magnetic Detection, Metallic Line Detection, Non-Metallic Line Detection, Plastic Water Pipe Detection, Sewer Crawler Inspections, Underground Utility Mapping, Sophisticated Reports, Structural & Concrete Scanning, Video Push Camera Inspection, and more.

Private utilities are usually located after the meter, which belongs to customers. Some utilities may also be considered private that exist on your property. Examples of private utilities are the water lines beginning at the meter down to the house, electrical wiring and installations, electricity, televisions, telephone lines, sewer and drain lines of structures that are detached, backyard lighting, water and primary electricity from wells, septic systems, satellite lines, as well as electric fencing for dogs, propane used in fire pits and barbeques, roofs’ drainage systems and so on. Such private utilities call for accurate detection and inspection professionals.

Owned by utility corporations, public utilities reach the boundary of private property lines or the meter base. Common practice involves dialing 811 before an underground excavation is carried out, which is the law (RCW 19.122.). While public utility locators are very helpful when carrying out underground work and avoiding public utilities, private utilities are not included in the 811 service. This is why it is necessary to utilize the services of a private utility locator such as C-N-I Locates Ltd since, in most work areas, fifty percent of the utilities are private. An underground utility strike takes place every one to two minutes in the United States; therefore, it is essential to hire C-N-I Locates Ltd and dial the 811 number to locate underground lines and avoid damages. Trust us for your most detailed utility location services for the safety of your project and to avoid probable risks.

Plastic Water Locating Services in Southern Washington

C-N-I Locates Ltd ensures its customers excellent as well as comprehensive plastic pipe detecting services across the whole geographical territory of Washington State. Newer homes or structures that were constructed after 1969 may likely adhere to the new codes and contain plastic water services. Plastic pipes such as ABS, CPVC, PEX, PE-RT, polybutylene, PVC, and more – present problems for electromagnetic detection since they are not conductible. To overcome this, C-N-I Locates Ltd employs the use of electronic pulse transmitters (EPTs) to send a pulse of water through the pipe systems, which is detectable with the use of our subsurface microphones to amplify subterranean noises.

Other methods to identify plastic pipes may include insertions with a metallic element or GPR.

Our expert technicians utilize modern equipment, which helps to locate plastic pipes beneath the ground. Small Electronic Pulse Transmitters (EPTs) and Large Electronic Pulse Transmitters (EPTs), which are also called strikers, stoppers, knockers, transondes, tappers, thumpers, and plastic pipe locators, are two kinds of devices we utilize when performing plastic pipe detection services. Subterranean microphones are used to record audible pulses or sound waves emitted by the Small EPTs in water pipes. Small EPTs can emit sounds to depths of more than 4 feet and a length of more than 300 feet depending on pipe size, depth, type of soil, and whether it has bends or angles. They work well with smaller household pipes up to 2 inches in diameter. Nevertheless, with the help of acoustical listening equipment, Large EPTs also generate pulses in larger water pipelines. These are perfect for water mains larger than 2 inches in diameter, audible down to 4 feet, and traceable up to 1000 feet. In some circumstances, pulses have been heard 30 feet below the surface on a 6-inch main and for over 1000 feet. Importantly, we offer immediate and reliable services to help you with all your infrastructural requirements and needs, and our services are available within one business days’ notice between Monday through Friday.

Underground Utility Mapping Services in Southern Washington

Our group of subterranean utility mapping specialists is critical to avoiding mishaps, cost overruns, time-consuming deviations, damaging impacts on one’s reputation, injuries, project slowdown, and additional time on project work. The significance of current information on subsurface utilities and features cannot be overstated as it enables one to take prevention measures in anticipation of any dangers, thereby preserving the rights of neighboring premises and the proposed construction.

Utility mapping is the highly technical process of identifying and documenting the positions of subsurface utilities and other workers using sophisticated GPS, GNSS, or RTK receivers. The most recent data is then put into site maps, leading to a useful tool for environmental engineers, subsurface workers, surveyors and builders, engineers, and future utility locating services in Washington. CNI Locates Ltd offers construction sites and new developments complete utility mapping services that supply projects with accurate data for increased productivity and safety, as well as efficient decision-making throughout the construction and development processes.
