Natural gas project review

Step 1

Request as-built drawings

---

Request natural gas infrastructure drawings for your project area:

• In Winnipeg, email City of Winnipeg Underground Structures.
• Outside Winnipeg, email Distribution Engineering Services.

Step 2

Determine if your project requires a review

---

Read our checklist (PDF, 55 KB) and check the as-built drawings to determine if your project requires a review.

• If a review is required, read the rest of the steps and include your natural gas infrastructure construction plans with your application.
• If your project does not require a review, no further action is required.

Step 3

Online application

---

Gather all the required information and supporting documents before you start the online application.

You must include all of the following:

• legal business name and contact information;
• construction plans (include natural gas infrastructure, and add a “caution – gas” note to your drawing set wherever gas mains are present);
• detailed description of any items installed outside of public right-of-way;
• vehicle and equipment descriptions and weight (both wheeled and tracked);
• crossing numbers and map of temporary equipment and vehicle crossing access routes.

Step 4

Request a line locate or safety watch

---

You must complete a line locate request prior to any excavation or construction operations. Work must start within 14 days of the completed underground locate. If the nature of the work changes or the marks become displaced, stop work and get a new locate.

Request a line locate or safety watch (minimum notices required):

• Line locate (3 business days);
• Manitoba Hydro safety watch (3 business days).

Step 5

Determine depth of existing natural gas lines

---

Work over any pipeline (regardless of size), cannot begin until the existing depth of cover by soft digging methods is determined.

Include all gas line depth information in your application for review.

Vibratory compaction methods cannot be used within 3.0 metres of transmission-pressure or high-pressure natural gas main, or within 1.0 metre of a distribution-pressure natural gas main or service line.

Static compaction of granular material can be built up in 300 mm layers until minimum cover is achieved.
