FCLU Public Seminar Environmentally Sustainable Trenchless Solutions For Underground Utility Projects In Urban Environments Dr. Samuel T. Ariaratnam Professor Del E. Webb School of Construction Arizona State University, USA Abstract The utilization of traditional open-cut methods for the installation of underground utilities has been common practice in the construction industry for many years. Today, engineers are being tasked with the requirement of selecting a suitable construction method that not only offers the most economical solution, but also minimizes impact to the environment. Trenchless construction methods offer such solutions for installing new utilities and rehabilitating existing infrastructure using “green” principles. The use of multiple construction equipment during open-cut construction invariably results in considerably more emitted emissions into the atmosphere compared to employing trenchless methods, which have minimal on-site equipment requirements. Pollutants such as carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxide (NOX), hydrocarbons (HC), sulfur oxide (SOX), and particulate matter (TM) are identified by the United States Environmental Protection Agency (US EPA) as being emitted from equipment engines. This paper describes a methodology for quantifying the emission effects (i.e. carbon footprint) of a typical underground utility project. A case study is used to demonstrate the reduction in emissions by adopting trenchless technologies. Additionally, the development of an innovative “environmentally-friendly” technology for the installation of critical grade sewers will be discussed. Reducing emissions into the atmosphere is a vital step in developing sustainable solutions. These environmental considerations are critical in sustaining our environment for the benefit of future generations.

The Hong Kong Polytechnic University About the Speaker Dr. Ariaratnam is a Professor at the Del E. Webb School of Construction at Arizona State University. He received his B.A.Sc. from the University of Waterloo (Canada) in 1989 and his M.S. and Ph.D. from the University of Illinois at Urbana-Champaign in 1991 and 1994, respectively. Prior to joining ASU, he spent five years as a faculty member in the Department of Civil and Environmental Engineering at the University of Alberta. From 1995-96, he was a Visiting Assistant Professor at the U.S. Air Force Academy in Colorado Springs, CO. His primary area of research interest lies in Sustainable Underground Infrastructure Management and Rehabilitation. Research in this area has focused on the development of new technologies in construction engineering and applications of underground trenchless construction techniques, specifically Horizontal Directional Drilling and Trenchless Pipe Replacement. He has published over 150 technical papers and reports, co-authored five textbooks, and is a co-holder of three patents. Through his research and educational initiatives, Dr. Ariaratnam has received recognition from the California Department of Transportation, City of Los Angeles, North American Society for Trenchless Technology (NASTT), and the American Society of Civil Engineers (ASCE), where he received the prestigious John O. Bickel Award. In 2003, he was presented with the Young Civil Engineer Achievement Award from the University of Illinois at Urbana-Champaign. Dr. Ariaratnam received an award of recognition from Halliburton Energy Services for contributions to underground technology in 2004. In May 2005, he was made an “honorary” member of the National Utility Contractors Association (NUCA) of Arizona. The Phoenix Business Journal named him to the prestigious “Top Forty Under 40” list in 2006.
