The construction industry publication Trenchless Works recently celebrated a half-century of advances in the Horizontal Directional Drilling, or HDD, underground construction method, beginning with an introduction written by Fulton Schools Professor Samiel Ariaratnam (pictured). On page 5 of the digital magazine, he details key accomplishments of HDD and its contributions to the evolution of the field of construction engineering. Ariaratnam, who holds the Beaver-Ames Chair of Heavy Construction at ASU, is a co-author of the “Horizontal Directional Drilling Good Practices Guidelines.” Today, Ariaratnam writes, “you can go to all corners of the world and see an HDD rig installing a critical utility for the betterment of society.” He foresees continued expansion of the HDD industry as its environmental, economic and social benefits are increasingly recognized.
