Abstract
Horizontal Directional Drilling (HDD) is defined as “A steerable system for the installation of pipes, conduits, and cables in a shallow arc using a surfaced launched drilling rig. Traditionally HDD is applied to large scale crossings such as rivers in which a fluid filled pilot hole is drilled without rotating the drill string, and this is then enlarged by a wash over pipe and back reamer to the size required by the product.” (Trenchless Data Service 2000). This technology has been in existence since the 1970’s. It is currently an efficient, safe, cost effective method for highway bores and is the current industry standard for trenchless technology for bores between 2 and 48-inch diameters and 600 ft to 1800 ft in length. However, according to the manual for Accommodation of Utilities on Right-of-way of the Illinois State Highway System - 1992, it is currently prohibited under state highways for bores over 6 inces. Bores of greater size must be done by the jack and bore method. The manual is being re-written and will include a provision for an HDD option, but it will not define the parameters under which approval can be granted. The objective is to study the effects of horizontal directional drilling (HDD) for utilities under pavement and within the right of way of the State of Illinois in order to aide in the writing of the policy and procedures for administering permit requests for HDD. This report covers Phase I of the work described under the scope of work section.
