Keeping your company and employees safe.
Having a specialized boom truck attached to the power pole removes any risk of the pole shifting, leaning, or falling over in a way that could cause catastrophic harm to workers, excavators, and surrounding infrastructure.
Pole holding guarantees the uninterrupted structural integrity of the powerline system, particularly when open civil excavations or trenching are conducted in close proximity to energized power poles.
Whenever excavations take place near BC Hydro power poles or municipal street lights, our Category 5 Powerline Technicians perform dedicated pole holding duties to keep the structure steadfast and secure, enabling your civil crew to execute their work safely and on schedule.
Pole holding services are essential for civil construction businesses, utilities, and excavation contractors working near live overhead infrastructure:
When operating heavy machinery around energized power lines, designated qualified personnel must be on site to monitor clearances. Both WorkSafeBC and BC Hydro mandate qualified observers on site whenever men and equipment work near high-voltage conductors.
A Safety Watcher is a certified Category 5 Powerline Technician responsible for protecting all site personnel by enforcing strict protocols for maintaining safe working distances from underground or overhead high-voltage utilities. A Safety Watch is required whenever standard Limits of Approach for unqualified workers or uninsulated equipment cannot be maintained.
We prioritize the safety and well-being of every individual on your construction site, ensuring their safe return home. Our team holds the requisite training and certification to direct operators around high-voltage overhead lines and underground utilities.
We exercise direct supervision over high-risk activities including tower and mobile crane operations, scaffold erection, concrete pump booms, zoom booms, and excavation near electrical lines in accordance with BC Hydro Limits of Approach (Table 401).
Should construction work fall within 10 feet (3 metres) of high-voltage overhead utilities, our on-site CAT 5 technician provides authorized safety watching, enabling the safe operation of uninsulated machinery up to the regulated minimum clearance (no closer than 4 feet for distribution voltages under CAT 5 supervision).
When operating excavators, mobile cranes, concrete pump booms, zoom booms, or scaffolding near energized overhead power lines in British Columbia, strict minimum clearance distances apply. A certified Category 5 Powerline Technician (Safety Watcher) is legally required whenever uninsulated equipment or unqualified workers must encroach closer than the General Limit of Approach.
| System Voltage (Phase-to-Phase) | General Limit (Unqualified Worker / No Safety Watch) | Assurance in Writing + CAT 5 Safety Watcher Limit | Typical Municipal / Utility Application |
|---|---|---|---|
| 0V – 750V (Secondary) | 1.0 m (3 ft 3 in) | Supervised Close Proximity | Residential service drops, street light feeds |
| 750V – 75kV (Primary Distribution) | 3.0 m (10 ft) | 1.2 m (4 ft) Minimum | Standard BC Hydro 12kV / 25kV wood pole lines |
| 75kV – 250kV (Sub-Transmission) | 4.5 m (15 ft) | 3.0 m (10 ft) Minimum | High-voltage regional transmission corridors |
| 250kV – 550kV (HV Transmission) | 6.0 m (20 ft) | 4.5 m (15 ft) Minimum | Major BC Hydro bulk transmission towers |

FIG 04A certified CAT 5 Safety Watcher is required whenever construction equipment, cranes, excavators, or scaffolds must operate closer than the standard 10-foot (3-metre) general Limit of Approach to energized overhead distribution lines (up to 75kV), allowing safe supervised operation down to 4 feet (1.2m).
Any excavation within the structural soil zone of a utility pole (typically within 3 metres of the pole butt or anchor guy wires, or deeper than 60cm near the pole) undermines soil bearing capacity and requires a boom truck to hold the pole during digging and backfilling.
Yes. Metro Power Construction dispatches CAT 5 technicians and pole-holding boom trucks 24/7 across Greater Vancouver, the Fraser Valley, and the Sea-to-Sky corridor.
