slide 2:

What is Utility Locating Utility locating is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication electricity distribution natural gas cable television fiber optics traffic lights street lights storm drains water mains and wastewater pipes. In some locations major oil and gas pipelines national defense communication lines mass transit rail and road tunnels also compete for space underground.

slide 3:

Public utility systems are often run underground some by the very nature of their function others for convenience or aesthetics. Before digging local governments often require that the underground systems locations be denoted and approved if it is to be in the public right-of-way.

DEVICES USED IN UTILITY LOCATING

slide 5:

Ground Penetrating Radar GPR is a large device that looks like a grass mower and is similarly pushed along the surface of the ground. It sends radio waves that penetrate down into the ground as it runs laterally the surface. When these waves come across a foreign object or change in the dielectric property of the material the waves bounce off to the GPR device. Ground Penetrating Radar

slide 6:

Any disturbance in the radio waves appears on the screen of the GPR device. A proficient technician can interpret the information to designate the type of underground feature.

slide 7:

GPR is used frequently to locate objects such as plastic concrete buried manholes pull boxes valve assemblies underground storage tanks changes in soil and other things that cannot be located using other methods. GPR is a required tool to detect the presence of non-metallic utilities and objects

slide 9:

Electromagnetic Scanning EM is a device that uses a transmitter and receiver to locate metallic utility lines. The transmitter is attached directly to a utility line through its surface feature. It will then send electrical currents down the utility line that can be traced by the receiver. The receiver is used to identify the peaks of the Electromagnetic fields generated from the electrical current. This is how most underground utility lines are located. EM can only be used to locate metallic utility lines. Electromagnetic Scanning

A Split Box another Electromagnetic scanner is a handheld device that has a transmitter on one end a receiver on the other and is connected together by a long pole. The device is carried along the surface of the ground and detects metallic objects present under the ground. In addition to detecting utilities the split box is required for locating abandoned utilities underground storage tanks buried manholes and other metallic objects. Not all utility locating companies use this device. Not using this device exposes the customer to unnecessary risks. Split Box

A Concrete Scanner is a smaller handheld Ground Penetrating Radar GPR device that is primarily used for concrete scans. The technician uses it by running it along the surface of the concrete. Using the same technology as GPR the concrete scanner sends high frequency radio waves into the concrete which bounce off of any changes in dielectric properties within the concrete slab. It can be used to locate conduits rebar wire mesh and other objects embedded within the concrete slab. Concrete Scanner

This device is a copper wire that is reinforced with fiberglass material. The reel is approximately 150 feet long. The duct rodder is used to find non- metallic utilities that are accessible from the ground surface. The wire within the duct rodder can carry a current which means that it can be hooked up to the Electromagnetic transmitter device to send a signal down the utility through the duct rodder. Duct Rodder

slide 13:

After inserting the duct rodder and connecting the transmitter to the copper wire the EM receiver can then be used to locate the electromagnetic fields emitted off of the duct rodder and in turn locate the utility.

A sonde is a small device that acts as a miniature transmitter. It is primarily used to pinpoint blockages or to locate unusually deep utilities. When the sonde is sent down a utility line it sends off high powered signals as it travels through the line. These signals can then be picked up on the surface of the ground locating where the sonde is in the utility. Sonde

slide 16:

A sonde is typically sent through a utility line attached to the end of a duct rodder however they are also built into the head of a CCTV push camera or robotic crawler. Sondes come in varying strengths. The deeper the utility the stronger the sonde device needed. The signal has to be strong enough to penetrate the soil and reach the surface of the ground in order to be detected.

slide 18:

A rebar locator or detector is used primarily for locating rebar and reinforcement in concrete. Using electromagnetic technology the rebar locator produces a magnetic field which the steel rebar responds to. A rebar locator can locate the location direction and approximate depth of reinforcement in concrete. Rebar Locator

slide 19:

A concrete thickness gauge is a non destructive technique used to measure the thickness and integrity of concrete slabs. It can also be used to detect voids cracks and other defects in concrete. Concrete Depth Gauge
