Webinar: 2024 No-Dig Show Outstanding Paper: New Installations

Join Us for Free Trenchless Education for NASTT Members!

Back by popular demand! NASTT is excited to present an encore of the 2024 No-Dig Show Outstanding New Installations Paper. Check out the abstract below and be sure to join us for this special presentation!

There are numerous rules of thumb used in the design and construction of HDD installations .One of the most frequently used is the design radius for HDD installations. Whether for steel, HDPE, or FPVC the rule-of-thumb design radius is often used as the final design radius. All too frequently, the design radius is also considered the minimum radius if a minimum allowable radius is not defined in the design. Because design radius affects the tolerances allowed for construction, this could place additional constraints on a project, which increases risk and project costs. In addition, the build rate that a contractor is required to maintain is directly affected by the design radius. If the tolerance window between the lower bound radius and the design radius is small, the contractor will have difficulty installing the pipe within the given tolerances. This paper reviews the purpose behind the rule-of-thumb radius, discusses the several radii used in HDD design and construction, and presents an approach to aid engineers and contractors in selecting appropriate radii and tolerances for HDD projects.
