The Purpose of Geotechnical Investigations in HDD: Feasibility & Efficiency
The primary purpose of geotechnical investigations in Horizontal Directional Drilling (HDD), which is to determine the feasibility of drilling and identify the most efficient methods for execution. The technical feasibility of an HDD project hinges on the subsurface conditions that the bore path will encounter. Geotechnical investigations help identify potential "show stoppers"—soil conditions that could prevent successful drilling, such as those that do not support open hole or fluid conditions. The data gathered also informs the evaluation of changing ground conditions across the crossing, influencing the project's feasibility, construction methods, layout, and design. Additionally, the information guides decisions on bore profile depth, alignment, and risk minimization, and aids contractors in selecting the appropriate equipment and tools for the drill.
