Locate Request Improvements for Very Large Excavation Zones

Great news! An important modification will be in effect on September 24th and will greatly facilitate your work. Indeed, as of September 24th, you will be able to draw sketches in a row. This will enable you to cover the whole area of your work zone when it extends further than what is displayed on the map.

This modification will result in:

• Viewing the adjacent sketches for your entire work zone when you create the request;
• Automatically creating a locate request for each of the sketches;
• Sending a confirmation for each locate request created.

There are many benefits to this major modification:

• Improves the efficiency of your activities;
• Heightens the accuracy of each locate request, leading to a quicker answer from our members;
• Provides the possibility of receiving a clearance notice for some section of the work zone;
• Simplifies the creation and management of locate requests for large excavation zones.

Click here where you can view a short video demonstrating what steps must be followed to take advantage of this change.

(For the province Quebec only) If you haven’t done so already, we encourage you to read our emails sent on August 24th and 31st where we mention the importance of writing the scheduled start and end dates as accurately as possible.

Details as to scheduled excavation start and end dates (only for the province of Quebec)

We would like to remind you that yesterday, a modification related to the locate request validation period was in effect. This modification will greatly benefit your operations:

  • You may receive, during the course of your validation period, notifications indicating that there were changes to the initial answer. Sent by email, these notifications indicate that underground infrastructures were added within the worksite specified in your request.
  • A notification will be sent 7 days prior to the expiration date of the validation period of your request, giving you enough time to renew it and complete your excavation work.

Remember that writing the start and end date as accurately as possible will have the following effect:

  • Decrease the number of revalidation;
  • Reduce the time spent managing your emails, which includes answers received from owners of underground infrastructures;
  • Lessen the number of follow-ups and your administrative workload.

It should be noted that the period between the excavation start date and its scheduled end date written on your request represents the period in which your request is in effect, thus valid.

Writing irrelevant dates means that everyone involved in the process, Info-Excavation employees and members of underground infrastructures as well, won’t be able to offer the same level of service that you have come to expect.

Participate in the CPWA Infrastructure Investment Survey

As the ‘the voice of public works in Canada’ and to better represent CPWA member interests as the CPWA Board continues to engage with the Government of Canada, CPWA is soliciting information from municipalities about infrastructure investments and their experience with federal programs. This input will inform the discussion when the CPWA Board of Directors meets later this month with Marc Miller, Parliamentary Secretary to the Minister of Infrastructure and Communities. Survey responses may also help inform CPWA’s public policy priorities and future engagement with Infrastructure Canada.

Participate in the survey.

Government working with Canadian Common Ground Alliance to protect federal underground infrastructure

News release

From: Public Services and Procurement Canada

June 21, 2018 – Gatineau, Quebec – Government of Canada

The Government of Canada is committed to maintaining the highest standards of safety for construction workers, Canadians and our federal public infrastructure.

Today, Steven MacKinnon, Parliamentary Secretary to the Minister of Public Services and Procurement, on behalf of the Honourable Carla Qualtrough, Minister of Public Services and Procurement, announced the signature of a memorandum of understanding between Public Services and Procurement Canada (PSPC) and the Canadian Common Ground Alliance (CCGA) to improve the protection of underground infrastructure, such as cables and pipes, located on federal lands.

Building on the important work of the Honourable Grant Mitchell, Senator for Alberta, and Lloyd Longfield, Member of Parliament for Guelph, to raise awareness of the protection of underground infrastructure, PSPC, together with the CCGA, will launch a pilot project to improve and coordinate current notification processes for work on federal lands. This will further strengthen existing processes and prevent damage to underground infrastructure. It will also ensure safety for the public and workers, and improve the safety of federally regulated underground infrastructure.

PSPC will be working with the CCGA and other government departments and agencies within the public service to facilitate a government-wide approach.


“Our government is proud to work with the Canadian Common Ground Alliance to reinforce measures that will further ensure the safety of construction workers and Canadians while protecting the federal underground infrastructure.”

Steven MacKinnon
Parliamentary Secretary to the Minister of Public Services and Procurement

Quick facts

  • Underground infrastructure generally refers to a cable, line, pipe, conduit or structure used to gather, store or convey products or services beneath the ground surface or submerged, including where exposed by temporary excavation.

Simplified Sketches

Since May 1, 2018, substantial changes to the creation process of sketches are in effect:

• Only the sketch is used to analyze your request;
• A second intersection is no longer needed;
• The possibility to zoom is restricted;
• The map cannot be moved once you have started the sketch.

Benefits and impacts from changes

These changes:

• Improve the accuracy of the sketches;
• Increase the clearance notice rate. Since May 1, 2018, there is a 14% increase. This reduces the number of answers received from owners of underground infrastructures;
• Eliminate automatic segmentation of many requests for the same section.

However, this has an impact on 30% of requests, namely an increase in the number of sketches for the same project.

Upcoming Solutions

These improvements are meant as an answer to the lack of accuracy observed in sketches. Also, distances were sometimes too long, thus harming the quality of requests. This, in turn, increases the risk of damages to underground infrastructures.

We realize these modifications affect some of your projects. We’re already working with our suppliers to find solutions to improve this process. We will keep you informed of the latest progress made.

Current Modifications

Enhancements in the Request Confirmation form

For some time now, the request confirmation form received by email has undergone some enhancements. As of today, your Google sketch will prevail and attest to the authenticity of the locate request. The area defined in your Google sketch will be the one that will be used.

New to Types of Work

A new type of work has been added. You can now select “Crane Installation”.






Faster Engineering Request

Great news! Owner members of underground infrastructures have agreed to reduce the turnaround time for an engineering request. It will soon be reduced from 10 to 5 business days.


Simplified Sketch

Since May 1st, a substantial change to the creation process of sketches has taken place. Indeed, it is no longer necessary to enter a second intersection. This improvement marks the end of automatic segmentation, responsible for creating additional locate requests.

As far as other modifications are concerned, the use of the zoom and arrows to navigate within the map and move it has been restricted, enabling the clear identification of the worksite. The added benefit translates into an increased number of clearance notices and a reduced number of replies received from owners of underground infrastructures.

Modifications to the Request Confirmation

As of March 4, 2018, modifications were made to our confirmation form, the one received after making a locate request. A warning note regarding the accuracy of your scaled diagram has now been placed on the right-hand side of your diagram. Furthermore, the artwork pertaining to the warning note has also been modified to enhance its readability.

*Important: As of today, only your scaled diagram will be used by our members to determine if their underground infrastructure is located or not within your work zone. Intersections and addresses will only be used to help guide you on our Google Map*.
