- Confidential Information. Except as otherwise excluded herein, in connection with the provision of the Services, the parties’ acknowledge and agree that either party (as the “Disclosing Party”) may disclose or make available to the other party (as the “Receiving Party”) information about its business affairs, products, services, confidential intellectual property, trade secrets, third-party confidential information and other sensitive or proprietary information, whether orally or in written, electronic, or other form and whether or not marked, designated, or otherwise identified as “confidential” (collectively, “Confidential Information”). Confidential Information shall not include information that, at the time of disclosure and as established by documentary evidence: (i) is or becomes generally available to and known by the public other than as a result of, directly or indirectly, any breach of this Section 15 by the Receiving Party or any of its Representatives; (ii) is or becomes available to the Receiving Party on a non-confidential basis from a third-party source, provided that such third party is not and was not prohibited from disclosing such Confidential Information; (iii) was known by or in the possession of the Receiving Party or its Representatives before being disclosed by or on behalf of the Disclosing Party; or (iv) was or is independently developed by the Receiving Party without reference to or use, in whole or in part, of any of the Disclosing Party’s Confidential Information. Nothing set forth in this Section 15 is intended to preclude the Receiving Party from disclosing any Confidential Information that is required to be disclosed under applicable federal, state, or local law, regulation, or a valid order issued by a court or governmental agency of competent jurisdiction. If the Receiving Party is required by applicable law to disclose any Confidential Information, then the Receiving Party must promptly provide notice to the Disclosing Party of the legal requirement, unless such notice is prohibited by applicable law, and the Receiving Party shall provide its cooperation to the Disclosing Party in any effort by the Disclosing Party to seek a protective order or other injunctive relief against disclosure. If the Disclosing Party’s efforts to prevent disclosure of the Confidential Information fails, then the Receiving Party shall only disclose that Confidential Information, which on the advice of legal counsel, is required to satisfy the legal requirement. The Receiving Party shall: (A) protect and safeguard the confidentiality of the Disclosing Party’s Confidential Information with at least the same degree of care as the Receiving Party would protect its own Confidential Information, but in no event with less than a commercially reasonable degree of care; (B) not use the Disclosing Party’s Confidential Information, or permit it to be accessed or used, for any purpose other than to exercise its rights or perform its obligations under this Agreement; and (C) not disclose any such Confidential Information to any person or entity, except to the Receiving Party’s employees, agents and representatives (collectively, “Representatives”) who need to know the Confidential Information to assist the Receiving Party, or act on its behalf, to exercise its rights or perform its obligations under the Agreement. The Receiving Party shall be responsible for any breach of this Section 15 caused by any of its Representatives. Upon the expiration or termination of the Agreement or at any time during or after the term of this Agreement, at the Disclosing Party’s written request, the Receiving Party shall promptly return, and shall require its Representatives to return to the Disclosing Party all copies, whether in written, electronic or other form or media, of the Disclosing Party’s Confidential Information, or destroy all such copies and certify in writing to the Disclosing Party that such Confidential Information has been destroyed. In addition to all other remedies available at law, the Disclosing Party may seek equitable relief (including injunctive relief) against the Receiving Party and its Representatives to prevent the breach or threatened breach of this Section 15 and to secure its enforcement. Should CNI seek injunctive relief, the Court shall require no bond or a nominal bond not to exceed $1,000.00.
- Miscellaneous. Customer shall not assign any of its rights or delegate any of its obligations under this Agreement without the prior written consent of CNI. The relationship between the parties is that of independent contractors. All matters arising out of or relating to this Agreement are governed by and construed in accordance with the internal laws of the State of Oregon and Washington without giving effect to any choice or conflict of law provision or rule (whether of the State of Oregon, Washington, or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than those of the State of Oregon and Washington. If any term or provision of this Agreement is invalid, illegal, or unenforceable, such invalidity, illegality, or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Should any provision be deemed unenforceable, the Court shall reform the language to reflect the parties’ original intent to the full extent legally allowed.
- Non-compete. At all times during the term of this agreement, and for a period of one (1) year following any termination of expiration thereof, contractor and client agree that they shall not, directly or indirectly, for themselves or on behalf of any person or entity solicit or contact any employees or customer of each other for the purpose of inducing them to terminate their employment or contractual agreements with either of them or to become employees or independent contractors of either of them or such person or entity.
- Electromagnetic Pipe Locator. The EM locator can passively detect the signals from live AC power or radio signals travelling along some conductive utilities. It can also be used in conjunction with a transmitter to direct connect, signal clamp, or provide induction on accessible, metallic pipes, risers, drops, tracer wires, etc. A current is sent through the pipe, cable, or wire at a specific radio frequency and the resulting signal can then be detected by the receiver. A utility’s ability to be located depends on a variety of factors including access to the utility, conductivity, grounding, interference from other utilities, signal distortion, and many others. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: RD8100 & Vivax vLoc3-Pro
- Magnetometer. The magnetometer detects the magnetic field of a ferromagnetic object. Larger metallic objects can be located at depths of up to 10’ or more but total depths will depend on the size, type, shape, and orientation of objects along with the amount of interference from other objects. For more information, please visit: Model GA-52Cx Magnetic Locator
- Traceable Rodder. The rodder has a copper wire encased in fiberglass. The line is pushed through accessible pipes before placing a current on the wire and the signal is then traced from the surface. The maximum traceable depth is 10’ depending on the soil conditions and the maximum distance is 400’. The line can be pushed through a pipe with direct access such as an empty conduit, sewer line at a cleanout, storm drain catch basin, etc. It may not be able to be pushed through deeper or larger pipes within manholes. The signal cannot be located through metallic pipes. Due to preexisting conditions (e.g., age of pipe, condition of the pipe, utilities in the pipe, diameter of the pipe, angles in the pipe, blockages, etc.) CNI cannot be held liable for any damages associated with providing the services. For more information, please visit: Jameson Traceable Rodder
- 512 Hz Sonde. The sonde can be connected to the end of the traceable rodder and pushed through an accessible pipe. This sonde transmits a signal at a 512 Hz frequency that can pass through cast-iron pipes or non-metallic pipes and be detected at depths of up to 5’-40’ depending on the conditions and type of sonde that is used. The signal can then be located from the surface using the EM pipe locator. Due to preexisting conditions (e.g., age of pipe, condition of the pipe, utilities in the pipe, diameter of the pipe, angles in the pipe, blockages, etc.) CNI cannot be held liable for any damages associated with providing the services. For more information, please visit: Radio Detection Sondes
- Video Pipe Camera (1”-8” pipes). This push camera is designed for video pipe inspection and pipe locating. It has a 1”-2” diameter, self-leveling camera head that provides high quality images in pipes 1”-8” in diameter. There is also a 512 Hz sonde behind the camera that can be located from above ground and provide the approximate depth to the pipe for pipes up to approximately 10’-15deep. The locatable signal from the sonde will not pass through metal pipes or solid metal barriers except for cast-iron. Access through a structure such as a cleanout, drain, etc. or an open pipe within arm’s reach is required for inspection service and locating. When inserted, the camera can be pushed through the pipe to a maximum of 325’ and past most angles in pipes, depending on the model being used and the size of the pipe. If the project requires entry into confined spaces to gain access to the subject piping, this will need to be coordinated by the client and a permit obtained if required. Video and photos of the interior of pipes can be provided along with inspection reports. Inspection reports are available upon request prior to execution of field work. Due to preexisting conditions (e.g., age of pipe, condition of the pipe, utilities in the pipe, diameter of the pipe, angles in the pipe, blockages, etc.) CNI cannot be held liable for any damages associated with providing the services. For more information, please visit: GatorCam4
- Robotic Crawler Camera. This modular, 4-wheel robotic video pipe inspection camera (crawler) is capable of 0° turns and equipped with varying wheel treads and sizes to adapt to most pipe applications. The crawler is typically used to inspect and locate pipes that are 8″ in diameter and greater. The crawler is controlled by an operator at the surface using a remote control that allows for video to be viewed live during collection so observations can be made and noted as the crawler travels through the pipe. This camera is equipped with a 512 Hz sonde behind the camera head that can be located from above ground and provide the approximate depth to the pipe for pipes up to 10′-15 The locatable signal from the sonde does not pass through metal pipes or solid metal barriers except for cast-iron. Access through a structure such as a manhole, catch basin, etc. or an open pipe within arm’s reach is required for inspection service and locating. When inserted, the camera can be directed through the pipe to a maximum of 1000′. For large diameter pipe applications (24″ and above) the crawler can be coupled with the carriage that allows for larger and more rugged wheels to be attached and a lift that raises the camera head up to 18″ allowing for the camera to be centered in the pipe for lines up to 36″ in diameter. If the project requires entry into confined spaces to gain access to the subject piping, this would need to be coordinated by the client and a permit obtained if required. Video and photos of the interior of pipes can be provided along with inspection reports. Inspection reports are available upon request prior to execution of field work. Due to preexisting conditions (e.g., age of pipe, condition of the pipe, utilities in the pipe, diameter of the pipe, angles in the pipe, blockages, etc.) CNI cannot be held liable for any damages associated with providing the services. For more information, please visit: Ibak Crawler
- Plastic Water Pipe Locator. The client must provide an unrestricted live access point with an adaptable fitting to an active water supply for our technicians to use electronic pulse transmitters (EPT’s) also known as plastic pipe locators, tappers, knockers, thumpers, transondes, etc. EPT’s average locating plastic water pipes between 100 feet to 150 feet in length (distance the pipe can be heard is not guaranteed) on plastic water pipes under 2 inches in diameter depending on multiple variables (e.g., pipe size, pipe depth, soil conditions around the pipe, amount of t’s in the pipe, angles in the pipe, backflow preventers, material of the pipe, noise in the work area, access to the pipe, etc.). In most circumstances, we are not able to hear pulses or thumps in pipes that are buried over 4 feet deep (depth the pipe can be heard is not guaranteed) that are under 2 inches in diameter. Horizontal accuracy should be assumed to be no less than +/- 2’ due to the nature of locating sound as opposed to an electromagnetic field. Client will assume the liability for damage to pipes or tripping of fire alarms if approval is given to apply this method. Plastic water pipe detection is not guaranteed and has a 90%+ success rate due to multiple unknown limitations that can prevent us from being able to hear the pulsing or thumping noises generated by our electronic pulse transmitters with our acoustical listening devices.
The water line must be inserted with a brand new (to avoid putting bacteria into the line) traceable rodder or wire (e.g., steel fish tape, flexi trace, flex rod, tracer wire, sonde, etc.) when the pipe is not locatable with our plastic water pipe locators or ground penetrating radar (client is responsible for the purchase of the brand new traceable rodder or wire). Once a traceable rodder or wire has been inserted into the plastic water pipe, we can identify the location of the rodder or wire by using an electromagnetic transmitter to send an electromagnetic signal through the traceable rodder or wire that we can detect with our electromagnetic receiver’s.
Small EPT’s produce a thumping or pulsing noise inside the plastic water pipe. With the use of an acoustical listening device these thumping or pulsing sounds can be heard above the surface at depths over 4 feet and for an excess of 300 feet in length, depending on multiple variables (mentioned above). CNI’s small EPTs are best suited for plastic water pipes up to two inches in diameter, even though they can be used on larger plastic water pipes with some success. A small EPT generates minimal water flow but enough to produce a loud pulse or thump.
Large EPT’s also create a thumping or pulsing noise in plastic water pipes, which can be identified with the use of an acoustical listening device. This thumping or pulsing noise can be heard up to 1000 feet in length and identified at depths over 4 feet depending on multiple variables (mentioned above). We recommend using our Large EPT’s on water mains over 2 inches in diameter. Our large EPT’s produce significantly more waterflow than our small EPT’s. For more information, please visit: RD500
- Acoustic Leak Locator. These acoustical listening devices are used to amplify liquid, gas, and air leaks, where a pipe may be compromised. The technician then designates where the greatest decibel readings are along the pipe and marks that location. The most elevated decibel levels may be along the shallowest point of the pipe, at an angle in the pipe or a union and/or a point where the pipe transitions to another material. The customer is responsible for providing direct access to non-conductive pipes to introduce a transmitter or traceable rod (to establish pipe location) and or roto hammering small holes in hard surfaces to minimize demo of asphalt/concrete and help isolate the break in the pipe.
Noise interference is one of the main limitations of acoustical leak detection. Noisy environments can make it challenging for acoustical leak detection to hear the sound of escaping air, gas, or water. Other sounds can interfere with the detection of the leak, such as high voltage electrical, running equipment, machinery, airplanes, traffic, rain, or wind. Furthermore, the depth of the pipe, material of the pipe, soil condition the pipe is buried in, shape of the leak, and size of the leak can also affect the sound the leak generates, making it more difficult to be heard in some circumstances.
Additional limitations that can occur are vapor barriers in the work area, unknown pipes that branch out from the pipe being tested, surface type in the work area, slopes in the work area, what side of the pipe the leak is located, property owner’s not being on site to let us test for the leak inside or to hook up our equipment to an unrestricted live access point with an adaptable fitting, plastic pipes (electromagnetically undetectable pipes), size of the pipe (pipes over 2” in diameter may need a commercial compressor), length of the pipe (pipes over 300’ in length may need valves installed), path of least resistance, obstacles in the work area, landscape matting in the work area, frost free hose bibs & backflow preventers that prevent compressed air from being introduced into the pipe, access to the pipe, ability to drill test holes in the work area, etc.
Due to all the limitations that can occur in a work area CNI cannot guarantee the ability to find all leaks. We will notify the client if we encounter any of the limitations mentioned above, so they can make the executive decision on how they would like to proceed. We may need to make a return visit to help identify the location of the leak, after the limitations have been addressed. For more information, please visit: Sewerin Leak Detection
- Infrared Camera. The thermal camera can detect changes in temperature as small as <0.1°C with accuracy with 2°C. This is often used for locating radiant heat tubing. The system should be heated near to or after the start of the project in order to have contrast between the temperature of the tubing and the slab. For more information, please visit: FLIR-i7 Thermal Imager
- Underground Scanning GPR Antenna. The antenna frequencies range from 250 MHz-800 MHz and are mounted in a stroller frame which rolls over the surface. The surface needs to be reasonably smooth and unobstructed in order to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the feasibility of GPR. The data is displayed on a screen and marked in the field in real time. The total depth achieved can be as much as 8’ or more with these antennas but can vary widely depending on the types of materials being scanned through. Some soil types such as clay may limit maximum depths to 3’ or less. As depth increases, targets must be larger in order to be detected and non-metallic targets can be especially difficult to locate. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: GSSI UtilityScanPro
- Concrete Scanning GPR Antenna. The antenna is handheld and rolls over the surface. The antenna needs a reasonably smooth, unobstructed surface for scanning and is not able to scan within 2”-4” of obstructions such as walls and metal tracks unless they are removed prior to our work. The data is displayed on a screen during the scanning and marked on the surface in real time. The total depth achieved can be as much as 18” or more with this antenna but can vary widely depending on the types of materials being scanned through and other factors such as the spacing of the reinforcing. No harmful radiation is emitted, and the work can be performed at any time with people in close proximity. For more information, please visit: GSSI StructureScanPro
- GPS. This handheld GPS unit offers accuracy down to 4 inches, however, the accuracy achieved will depend on the satellite environment at the time of collection and should not be considered survey-grade. Features can be collected as points, lines, or areas and then exported as a KML/KMZ or overlaid on a PDF drawing. For more information, please visit: Geode
- Aerial Drone Imagery. The drone is a portable unmanned aerial device which is used to view, inspect, and capture surface features in the approved project areas. Drone pilots assess the weather conditions prior to dispatching and again when on the project site while performing a site walk of the work area and checking the surrounding terrain to ensure a safe flight path. The flight time of the drone is calculated after evaluating the current weather conditions, with flights varying from 10 to 20 mins. Drone deployments require an FFA minimum of 3 square miles of visibility in order to deliver safe and appropriate data for the project. Prior to dispatching to the job site, the client will need to make sure the work area is compliant with FAA regulations, and if any regulatory notice is required. Flight data collected can be delivered in DWG and/or DGN CAD files, drone background image geo TIF file, an obj mech file, an XYZ point cloud, and a PDF plan print out of the CAD sheets.
