Horizontal direction drilling, or HDD, has been transforming the way power lines, gas lines and fiber optic cables are installed underground. Fulton Schools Professor Sam Ariaratnam, chair of the construction engineering program, has been at the forefront of research leading to HDD advances that have and made the technique standard practice in the underground construction industry over the past two decades. In an article reporting on how HDD is reshaping modern urban landscapes in Canada, Ariaratnam talks about the technical and environmental benefits being demonstrated by this minimally invasive drilling method.
