We have experience conducting both desktop and field constructability reviews to help identify site constraints and design parameters. Pipe stringing and pullback areas will also be identified behind the bore access points, to allow the HDD contractor room to operate.įrom civil and environmental services to mechanical pipeline design, we provide HDD design services to fit your project and get you around obstacles to a finished pipeline. This design needs to prioritize the safety and preservation of the surface obstruction, while remaining mindful that unnecessary HDD length and depth will increase construction costs. Our engineers pay special attention to develop a geometric design of the HDD bore to take into account the entry and exit angles, pipe size, and minimum radius and depth required beneath the surface obstruction. can all affect the length and depth of the HDD bore design. Steep slopes, proximity to buildings or structures, geology, landowner requirements, etc.

In those cases, a Horizontal Directional Drilling (HDD) method will be necessary to route the pipeline below the surface obstacles.Įach pipeline obstacle and situation is unique so before an HDD contractor can unleash their boring equipment the areas on either side of the obstruction need to be evaluated to determine feasibility of exit and entry points for the bore. Sometimes, significant and/or sensitive obstacles like large streams, rivers, water bodies, extensive wetlands, railroads, or major highways, where conventional open cut, or jack-and-bore pipeline installation methods are not practical or permissible. There are always obstacles encountered when routing a pipeline. Horizontal Directional Drilling Designing around obstacles
