THE HOMEOWNER & THE ONE CALL PROCESS

We receive phone calls daily from Homeowners who we assist in understanding the process and importance of placing an AB One Call prior to their ground disturbance projects and prior to hiring 3-D to locate their underground utilities.

There are many misconceptions with placing an AB One Call. So we are here to answer  these common questions we are faced with.

Q: I called AB One Call and they aren’t going to be able to come out to locate for 1-2 weeks and I want to dig this weekend. Can’t we just hire 3-D to come and locate for us?

A: The answer is yes 3-D Can come and locate for you, although, we strongly suggest that you place an AB One Call first. This service is FREE to the public and it ensures that all the registered utilities have been accounted for by the companies themselves and reduces the liability for all parties. The utility owners have their own locators that respond for each registered utility.

 

Emergency or Priority locate requests can be placed by calling 1-800-242-3447. To make an Emergency or Priority request, you must be digging to perform a repair to correct a condition that poses an immediate threat to life, health or property – including repair of essential services such as water, power, phone or gas. 

If you require locates sooner than three full working days because your request was not placed in time, the utility owners and their locators will not likely be able to accommodate you any earlier than three full working days due to the volume of requests they are processing.

Q: How do I know which utility companies need to respond to me?

A: On the bottom of your One Call Ticket, that you will receive, it will list all the registered utility owners for your work area. You should be contacted by a locator from each company.

 

Q: What if I haven’t heard any responses and it’s been over 3 full working days? Can I dig?

A: No. You need to have those buried facilities located. Hitting a line can be costly, as well as a danger to your own safety.

No. It is not safe to dig until all locates have been completed, or you have been provided with clearance to dig from each utility owner notified on your locate request. 

If a member of Alberta One-Call has been notified and has not contacted you within the three full working days advance notice period, or has failed to mark the locations of buried utilities as arranged, contact Alberta One-Call at 1-800-242-3447. We will contact the member to expedite a response on your behalf. Via www.abonecall.com

 

Q: Why am I being told I need to hire a secondary locating company to come out now?

A:  Alberta One Call explains it best :

Most, but not all, utility owners have registered their lines with Alberta One-Call. There may be utilities on your property that they are unaware of.

The utility owners and their locators are unable to mark:

  • Privately installed lines (e.g. power from your house to your garage).
  • Secondary lines (e.g. electrical lines past the meter).
  • Customer-owned utilities (e.g. water and sewer lines are the responsibility of the property owner past the shut-off valve at the property line).

 

The utility company does not own these lines and therefore does not have any information about their location. In some areas, some utility owners may charge to mark these lines. Via www.abonecall.com

 

This is when you can place a call to 3-D Line Locating Ltd. to come to locate for a secondary sweep of your work area for a fee.

3-D is here to help anytime for anyone that has questions or may be finding it difficult to understand the process of placing an AB One Call. We take the time to explain to homeowners this process and to avoid the liability of not placing an AB One Call prior to any ground disturbance they are planning on doing. It is a SAFE- FREE service to the general public and it should be taken advantage of first prior to contacting a secondary locating company when or if needed. By doing so it protects everyone and continues to promote a Safe Digging Culture and Awareness

Let’s talk about 3-D’s Stress Concentration Tomography (SCT) Services.

What is Stress Concentration Tomography (SCT)?

SCT is a passive magnetic sensing tool that collects the magnetic data of a target pipeline and then analyzes it for self magnetic-flux leakages in the pipeline wall, which are know as Stress Concentration Zones(SCZs). Using this stress-profile information, integrity managers can make informed decisions regarding the safe operation of their pipelines.

What does SCT Identify?

SCT™ identifies the location and the estimated stress of each SCZ (Stress Concentration Zone) on a pipeline.  An SCZ is an accumulation of localized stress in the pipeline wall that is greater than the nominal hoop stress of the pipe.  SCZs are caused by corrosion, metallurgical defects resulting in wall thickness loss and mechanical sources such as twisting and sagging from poor support and ground movements.  In turn, the increased localized stress within an SCZ prompts a localized realignment of magnetic domains which appear as an anomaly in the background magnetic field.

SCT™ identifies the particular magnetic signatures associated with different types of localized stress in the pipe and can differentiate between unexpected changes in stress caused by, for example, corrosion and expected changes in stress caused by girth welds.  After mathematical processing, localized stress increase, no matter what the source, generates the same waveform and SCT™’s automated search algorithms can identify their locations to cm accuracy.  Algorithms also have been developed and trained to examine the characteristics of each magnetic signal within the SCZ to estimate the quantity of stress causing them.  Significantly this is done directly through analysis of magnetic data without any intermediary analyses of wall thickness loss calculations, any need to excavate, calibrate, verify or alter the pipeline in any way prior to or after inspection.

 

Stay tuned this week as we talk more in depth with our SCT Services and what 3-D can do.

Spring Projects & Safe Digging

Whether the projects are large scale, or simply digging out a new garden or putting up a fence, everyone is required to Click Before You Dig.

Ground Disturbance, that is, any work, operation or activity that results in a disturbance of the earth, requires that you contact a One-Call center in order to learn what utilities are buried in your dig site. Common utilities are pipelines, power-lines, natural gas lines, sewage and water lines, internet and TV lines.

Some utilities are buried less than 60cm deep. Disturbance protocol states that when digging to a depth of more than 30cm an AB One Call Ticket should be placed and the utilities should be located prior to excavating.

What’s the risk?

For one, you could get seriously hurt. In some cases, it can even cause death. If you hit a gas line, it could cause a gas leak, and it takes just one spark to cause a major explosion. If you hit an electrical line you could be electrocuted. People have lost limbs, suffered brain damage, severe burns and/or died because they hit an underground electrical line.

You could also cause property damage — not just to your own home but also to your neighbours’ property, or the city’s. Hitting a water line could flood your home or a city street, and hitting a sewer line could lead to contamination.

There’s also the monetary cost. At the end of the day, guess who’s stuck with the repair bill? That’s right: you are. Some homeowners may even face legal action.

Before you pick up that shovel, remember to always ClickBeforeYouDig.com prior to every digging project. Having buried utility lines is a free service; there’s no excuse not to call or click. Plan your landscaping projects ahead of time and request a locate one week in advance.
