🚧Ground Disturbance Level II

Certificate Code: GS-GD- | Duration: ~3 Hours | Modules: 12 | Exam: 20 Questions | Pass Mark: 80%

“Over 400 buried infrastructure strikes happen in Alberta every year. Every one of them was preventable.”

Ground disturbance in Alberta is some of the most regulated work in the country — because beneath Alberta’s surface runs tens of thousands of kilometres of oil and gas pipelines, power lines, fibre optic cables, water mains, and sewer lines. Strike the wrong one and you face a fire, an explosion, a toxic release, or multi-million dollar liability. This course is your complete guide to digging safely and legally.

What You Will Learn

Apply the Alberta Pipeline Act 30-metre notification requirement before any ground disturbance near a pipeline
Submit Alberta 1-Call locate requests correctly and understand what the 3-business-day wait period means legally
Interpret all 7 locate marking colours and understand the ±0.5 metre tolerance zone around every mark
Execute vacuum excavation (potholing) to confirm exact utility position before mechanical digging
Classify soil as Type 1, 2, or 3 and apply the correct sloping ratio (3:1, 1:1, or 1:1.5) for each
Select and properly use trench boxes, hydraulic shoring, and sheet piling for excavation protection
Respond correctly to a gas line strike: evacuate 300 metres upwind, eliminate ignition sources, call 9-1-1
Perform and document daily excavation inspections as a competent person under Alberta OHS Code Part 33

Who This Course Is For: Required for Ground Disturbance Supervisors on Alberta industrial projects and pipeline right-of-ways. Essential for excavator operators, project managers, safety coordinators, and anyone who plans or supervises ground disturbance activities.

Why It Matters: A natural gas pipeline strike can create a lethal explosive atmosphere over a 300-metre radius in minutes. A trench collapse exerts the crushing force of 8,100 kg per cubic metre of soil. The locate call and the daily inspection are the two tools that prevent both.
