Title: Considerations of Design and Construction for Horizontal Directional Drilling

Currently, 55% of the world’s population lives in urban cities. This figure is expected to increase to 68%-75% by the year 2050 as people look to urban centers for employment opportunities. The influx of people moving into urban centers, combined with rapidly aging underground infrastructure, has resulted in an increased need for the installation of new utility services. Furthermore, the growing trend towards telecommuting, distance learning, and increased online commercial activities has intensified the need for improved fiber optic networks to meet these demands. The use of Horizontal Directional Drilling (HDD) has risen to these challenges on a global scale with adoption in all corners of the world. HDD is a versatile trenchless method that has a wide range of applications.
