Horizontal directional drills (HDD) have become an essential pipeline construction tool for crossing spans of the right of way with obstructions such as wetlands, rivers and streams, railroads, roads, businesses, and high consequence areas (HCA). This trenchless technology allows a pipeline to be installed without open cutting the ground. Prior to any construction, geological surveys with core samples are performed to determine the optimum route for the HDD (Figure 1).
