24-Inch Directional Drill Under Kansas River

24-Inch Directional Drill Under Kansas River

Location: Kansas City, Kan.

Client: Kansas City Board of Public Utilities

Completion Date: 2003

Burns & McDonnell performed design- and construction-related services for the installation of a new 24-inch water main crossing the Kansas River in Wyandotte County, Kan. The new water main replaced an existing main which was supported from the Turner Diagonal Bridge. The project consisted of the development of concept design criteria, an alignment study and final design bid documents utilizing horizontal directional drilling. Directional drilling methods were used to install approximately 1,800 linear feet of steel pipe below the Kansas River bed, and an additional 500 linear feet was installed using open cut methods. Burns & McDonnell evaluated two separate physical alignments for the new main. In addition, comparative analysis of installation methods and pipe materials were included in the conceptual study phase.

Horizontal directional drilling was chosen as the recommended option. Burns & McDonnell specified the requirement for entrance/exit angles, fluid pressures, depth, size of pilot holes and the required bore hole (36-inch diameter). All pipe was welded steel half-inch pipe. Special coatings were used for exterior pipe protection (a 20-mil fusion-bonded epoxy and an 80-mil PowerCrete® to protect the epoxy during pipe pull-back).

Burns & McDonnell assisted BPU in obtaining site survey information (including river cross-section), geotechnical data and permit approval through the Kaw Valley Drainage District. As the local sponsor, Kaw Valley Drainage District submitted plans to the Kansas City District Corps of Engineers for review and comment. In addition, Burns & McDonnell provided an on-site construction supervisor for the entire project.
