There was a time, back in the 90s, when the horizontal directional drilling market was a huge segment of the annual Underground Construction Technology International Conference & Exhibition. Since then, UCT has grown to truly encompass all aspects of the underground marketplace with construction and rehabilitation of sewer and water systems topping the list.
With the advent of new construction technologies comes the need for proven field tests to advance their use. Horizontal directional drilling (HDD) using ductile iron pipe, first introduced in 1994, is a method of installing the pipe underground without digging a trench.
Despite pockets of negativity, the majority of horizontal directional drilling contractors continue to enjoy a robust business atmosphere for 2013, and most expect that environment to continue for the foreseeable future.
Horizontal directional drilling (HDD) continues to solve problems for utility owners and operators by completing difficult installations of underground infrastructure that many times can be addressed by no other method of construction.
The Ohio Department of Transportation (ODOT) is reviewing a draft of a proposed Standard Specification for Horizontal Directional Drilling which would ensure quality trenchless installations of underground pipelines and conduits.
In a part of the country where rocky soils make underground construction difficult, Maine contractor Enterprise Trenchless Technologies, Inc. (ETTI) has built a solid reputation for successfully completing challenging horizontal directional drilling installations, many beneath bodies of water.
