A. Whether the ground disturbance is to take place on public or private land, the Occupational Safety & Health Code requires that ALL buried facilities potentially in conflict with the ground disturbance be identified & their horizontal alignments marked out before the ground disturbance begins. The requirement to have the locations of ALL buried facilities marked applies to the ENTIRE digging community, NOT just contractors. Making arrangements to have locates done should be part of the job planning process, big or small.

A. Although the one call service is effective for locating licensed, primary utilities, there is a large network of private or secondary infrastructure that is not covered by the One Call system. These facilities are equally as dangerous to contact as their primary counterparts. A 3rd party sweep covers this gap and provides you the peace of mind knowing you have done your “due diligence”.

A. We use a combination of specialized equipment combined with certified and competent technicians working in teams of 2. The equipment we use applies an electromagnetic frequency or “signal” by induction or by direct connect method to an insulated conductor (pipe or cable) with the transmitter and detects the frequency radiating from the conductor with the receiver.

A. Primary lines are utility owned and a member or contractor of the utility company will come and locate those lines. These include any utility line running up to and before the meter, main connect or primary disconnect point. Any lines that are not the primary feeds that may run from a house or business to service another building or area is secondary and is customer owned. Those lines will not be marked by a utility company and are the responsibility of the owner. Sometimes this even includes the main power feed to your home or business. Another great reason to get a 3rd party sweep performed.

A. Locate marks are good for up to 14 days and subject to conditions. For further information contact us.

A. If a plastic line has a tracer wire then it can be located using our specialized locating techniques. If there is no tracer wire, we are still able to locate plastic lines in some instances using highly advanced utility detection methods.

A. A sweep or scan is a two man process that involves using a transmitter and a receiver to find locatable underground utilities whether operating or abandoned in a specified dig or “work” area and is performed in a multi angle grid pattern. This process has an advantage over basic methods as it does not require direct access to the utility and can detect utilities cut off at both ends. For your safety 3-D Line Locating strongly recommends having this done to completely satisfy stringent Ground Disturbance Requirements. Even the ground disturbance work done in your backyard is governed by Provincial and Federal laws surrounding safe digging procedures.

A. What you probably witnessed was someone using passive locating methods which have a large margin of error as the “target” line is never established. They are merely detecting “a signal” and not “the signal”. While this is a form of line locating, there is a very large possibility of mis-locates or completely missed lines all together.
