Iseley, the Center's original Director from 1989-1994, rejoined as Director in 2014 a•er serving in various utility, academic and private in- dustry roles in the interim. Iseley remains as Associate Director of TTC's International Operations, and together with co-founder Dr. Les Guice, who now serves as Louisiana Tech's president, they provide experience and guidance to support Matthews as TTC writes its next chapter. Background and History The Trenchless Technology Center (TTC) was initially formed as the Trenchless Excavation Center in 1989 and formally estab- lished as the TTC in November 1991. It was created to promote research, education and technology transfer in the trenchless technology industry at a time when the market was still very much in its formative stages. To provide some context, the first U.S. microtunneling project took place in 1984, the International Society for Trenchless Technology was formed in 1986, and the North American Society for Trenchless Technology had yet to be established. The idea for the Center came as Iseley, then doing doctoral research at Purdue University, saw a need for bringing together researchers, industry and government, similar to what had been done with co-operative research centers in the transportation in- dustry. "I was doing research for the Indiana Department of Transpor- tation and I was looking for information related to means and methods of putting pipelines underground without trenching ," Iseley recalled. "I quickly realized that there was limited informa- tion available, and I saw a need for a research center that focused on underground infrastructure." With the support of Louisiana Tech and Guice, who at the time was head of the Civil Engineering Department, the Center was formed. With little funding and only a few graduate researchers available, the Center was o˜cially underway. One early project put TTC in the spotlight – the $1.2 million Construction Productivity Advancement Research (CPAR) pro- gram. This joint eœort by TTC and the U.S. Army Corps of Engi- neers was one of the largest trenchless research projects ever con- ducted. It included full-scale field research experiments on seven pipeline rehabilitation systems from five manufacturers; micro- tunneling systems under controlled ground conditions with ex- tensive instrumentation and monitoring; and small directional drilling systems. The findings of the research led to the develop- ment of the "The Guidelines for Trenchless Technology: CIPP and FFP Rehabilitation Systems, Mini-HDD, and Microtunneling." "The CPAR program was very important in establishing an en- gineering foundation for trenchless construction and helped kick- start the TTC, as well as the industry," Matthews said. Another important step in laying the groundwork for TTC was the establishment of an Industry Advisory Board (IAB), which provides financial support, expertise and guidance. " Working closely with the Board allows us to be in tune with the needs of the industry and what type of support or research they need," Matthews said. Starting from a base of 11 original IAB members, TTC now boasts nearly 50 members representing a cross section of the in- dustry. Organizations like the Louisiana Contractors' Educational Trust Fund (CETF) play an important role in supporting the TTC. Transitions When Iseley decided to pursue opportunities in private indus- try, Dr. Ray Sterling would become the next full-time TTC Director in 1995 (Dr. Paul Halada served as interim director from 1994- 95). Under Sterling , TTC increased its focus on municipal users, launching the popular Municipal Forum program in 1998. The Municipal Forum is a one-day educational event, primarily tar- geted to municipalities and their consultants, to learn the latest developments and share information in a collaborative setting. To date, TTC has hosted about 200 Municipal Forums across the country – about 10 per year. Another major step for TTC came in 2007 when the state-of- the-art National Trenchless Technology Research Facility was dedicated. This 5,000-sq • facility was funded primarily by In- dustry Advisory Board members and is the largest dedicated trenchless technology research facility in North America. The laboratory is fully equipped to perform most research functions and includes a strong floor, two soil boxes, a full material testing system, plus an outdoor in-situ pipe testing field. Research and development also continued to play a key role under Sterling's leadership, and continued a•er he stepped away in 2009 under the tutelage of Dr. Erez Allocuhe (Research Direc- tor) and Dr. Rob McKim (Administrative Director). It was during this time that TTC was principal author of the landmark EPA re- port "State of Technology for Rehabilitation of Wastewater Col- lection Systems" – a first-of-its kind summary and description of products available for sewer rehab. Following McKim's passing in 2013 and Allouche pursuing private practice, Iseley was invited to re-join the center he began more than a quarter century ago. Upon his return in 2014, Iseley was proud of the Center's part accomplishments but looking for- ward to taking it to new heights. Expanded Vision While the core mission of TTC has remained largely intact – research, education and technology transfer – it has undertaken several new initiatives that is changing the direction in how goals are being achieved. Special Schools To begin, TTC has begun oœering specialty schools to provide in-depth discussion of particular topics. " We wanted to go be- yond just increase awareness, but increasing understanding of the methods, including potential certification," Iseley said. In 2015, TTC held its first auger boring school at the Louisiana Tech campus. Recognizing that this trenchless method has not been receiving the recognition that was so visible in the 1980s and early 1990s, TTC set to develop a permanent training facility and develop a training program that would be oœered recurrently. A•er introducing the Auger Boring School, TTC launched the Utility Investigations School (UIS). TTC teamed with the Ameri- can Society of Civil Engineer's Utility Engineering and Surveying Institute (UESI) to provide an intensive five-day course in August 2016. The class gives attendees the knowledge and tools to pro- vide competent utility investigations in accordance with accepted national standards.
