HDD equipment requires a relatively short set-up time; a mini rig can be set up and start boring within an hour. Labor requirements are minimal, as it only takes a small crew to operate a small drilling rig. The need for traditional excavation during horizontal directional drilling is minimal or non-existent.
In open areas, directional drilling is an efficient was to cross rivers, highways, railroad tracks, even active airplane runways, without major disruptions to traffic or costs for traffic management. In crowded urban areas, horizontal directional drilling is increasingly viewed as “the preferred technology” because: •Surface disruption is minimized
- Restoration costs (roads, infrastructure) are minimized
- Less impact on residents and businesses
- Minimizes the need for earth removal and the long-term costs of trench settlement
