Horizontal Directional Drilling on the Snoqualmie River: A Case Study
The Kimball Creek project was a 1,000-foot long crossing of the Snoqualmie River near Snoqualmie, Washington. The 16-inch diameter DR-9 HDPE pipe was installed by Horizontal Directional Drilling (HDD). Staheli Trenchless Consultants (STC) provided submittal review and full time consultation during construction. As part of the submittal review, STC independently checked the contractor's estimated pullback forces for the pipe length, diameter, and type. During construction, actual pullback forces were recorded and were later compared to both STC's and the contractor's predicted pullback forces. This paper discusses the construction for this project and compares actual pullback forces to the contractor's and engineer's predictions.
