As a horizontal directional drill user, your job is to support construction efforts and use HDD equipment to lay an underground utility line without having to dig down from the surface. Horizontal directional drillers help install pipes of various sizes under different obstructions, including dirt, roads, railways, rivers, and other impediments. In many cases, this job requires maneuvering the drill to avoid existing pipes, particularly those containing natural gas, electricity, water, or sewage. Most drillers in this industry work in teams, though you may work independently for small jobs. This job may require working evenings, nights, weekends, or holidays as necessary to meet a construction schedule.
