Capability Applied

From the earliest stages of project planning to construction, closeout, and completion, we couple capability with good company. Call it professionalism or simply doing right by our work; we get it done.

Talent, teamwork
& tooling

We mobilize a fleet of over 350+ vehicles and powerline-focused equipment ranging from heavy-duty crew cab trucks to transport trucks, a full line of tracked machines, horizontal directional drillers, diggers, aerial devices, and complete wire stringing equipment set-ups and supporting equipment and tooling for major transmission work.

Since our founding, we’ve continually invested in transmission and distribution equipment and maintain a high-quality preventative maintenance program to keep that investment in a state of readiness.

If we have a difficult job, we know Magnum's going to get it done.

Drone Work
Our FAA-certified pilots manage a fleet of use-specific drones to perform construction, inspection, and surveying tasks with new efficiencies that mitigate a range of helicopter, boom, and climbing work.

The ability to digitize construction sites, collect data and imagery, and perform unmanned aerial work creates opportunities for more informed decision making and cost efficiencies:

  • Material Handling
  • Inspection
  •  Imagery & Documentation
  • Surveying
