![]() Directional boring offers an innovative solution for safer, non-invasive utility installation, especially on a busy site with potential surface obstacles. Mitigate Surface Impact Without Sacrificing Resultsĭetermining the most effective excavation method for an infrastructure upgrade is crucial to setting your project up for success. In fact, mapping deliverables are a tool that can be updated for the life of the facility. The mapping deliverable also provides owners with accurate documentation they can use for facility management and future planning. This provides data to minimize the potential for dangerous utility impacts that could stop service by informing design, planning the work and increasing safety. That’s why detailed knowledge is paramount prior to planning an infrastructure upgrade.Ĭombining subsurface utility mapping with directional drilling creates a valuable set of resources to enhance safety and minimize demolition for your project.Ĭastle performs initial subsurface utility mapping to get an accurate picture of the exact position and location of existing utilities, live or abandoned. Understanding campus operations, how to efficiently put work in place and maintaining public safety are major objectives for the project team. The key to the successful execution of utility projects is collaborating early and planning detailed task sequences. Potentially reduce construction and restoration cost.In these sensitive areas, directional boring offers many benefits including to: Crews patch up the small pits and the area above the entire alignment is unaffected.ĭirectional drilling is commonly used where cut-and-cover utility installation is not ideal, typically where the pathway encounters obstacles.ĭirectional boring can work beneath pedestrian pathways, roads, railroads, wetlands, water bodies or in areas with dense utilities. Finally, the utility is pulled through the enlarged borehole for the length of the pathway.Dirt and debris are extracted along the way. Next, the pilot hole is enlarged as the drill pipe bores back and forth along the alignment using a larger drill bit attachment until enough space is created to allow installation of the utility.Then, a rotating drill rod with a bit attachment is used to create a small diameter pilot hole along the path from the start point to the endpoint. ![]() A small pit is excavated at the start and endpoints.Starting with small potholes, an experienced directional boring crew exposes known utilities along the path to determine exact utility depths.The four-step process for successful horizontal drilling is as follows: A directional boring machine is designed to handle the unique stresses of horizontal drilling over distances ranging from just a few yards to several hundred yards if required. Horizontal Directional Drilling (HDD) is a proven process that involves specialized equipment. Working from prepared potholes away from busy roadways or sidewalks, directional drilling offers a smaller footprint while achieving the same results. Underground utility boring can be disruptive in such an environment, but horizontal directional boring offers an attractive solution. The Infrastructure Solution: Directional Boring There’s a complex web of electrical, cable and plumbing infrastructure underground, and documentation gets less reliable the further back in time it reaches. Before the new building can be erected, infrastructure must first be updated. This new building project is in the middle of it all, alongside decades-old infrastructure, roads and pedestrian routes. The new facility is an enormous undertaking, considering the campus has been built over the course of 50 years or more and the campus attracts thousands of visitors daily. Plans have been made for a new building project that will attract new students and staff. Imagine managing new construction on a busy sprawling university or hospital campus. What Are the Benefits of Directional Drilling? This process uses a directional drilling rig on the surface to install utilities along a path underground without digging open trenches for the entire utility length. What Is Directional Boring?ĭirectional boring (also referred to as horizontal directional drilling or simply directional drilling) is a minimal impact, trenchless excavation method. While especially popular in busy urban centers, horizontal directional boring provides a non-invasive and low-impact way to install important infrastructure efficiently. Directional boring is a solution to a common construction challenge faced by developers the world over.
