We are proud to spotlight one of NASTT’s Student Chapters, the University of Texas at Arlington! 
The University of Texas at Arlington’s Student Chapter was formed in 2006 and is one of the most active student chapters with over 60 members! The students are introduced to trenchless technology by classroom instructions, field trips, and guest speakers.
The objectives of the Chapter are to train graduate and undergraduate students under the supervision of the Chapter Faculty Advisor, Dr. Mohammad Najafi, while focusing on Underground Construction and Trenchless Technologies.
The UTA Student Chapter is a vital part of NASTT and their volunteerism during NASTT’s annual No-Dig Show is key to the success of the conference. This past spring, the Show was held near Dallas, Texas, just a few miles from the UTA campus and the conference benefited by having so many student volunteers on site.
Great job UTA! The North American Society for Trenchless Technology’s Student Chapters, working to build the future of trenchless!

Swiftly-Assembled Machine to bore Emergency Water Supply Tunnel
After an Onsite First Time Assembly (OFTA) lasting just 2.5 months, Atlanta Georgia, USA’s newest TBM, dubbed “Driller Mike”, made its initial startup on October 13, 2016 and ramped up to full production two weeks later. Atlanta’s Mayor Kasim Reed and city officials gathered with local and national media to celebrate the occasion. The 3.8 m (12.5 ft) diameter Robbins Main Beam TBM is now boring the 8.0 km (5.0 mi) Bellwood Tunnel after being walked forward 100 ft into a starter tunnel. The Bellwood Tunnel path will travel from an inactive quarry and run below a water treatment plant and reservoir before ending next to the Chattahoochee River.
The project was green-lighted by the City of Atlanta’s Department of Watershed Management due to the city’s 
current emergency water supply shortage. The PC/Russell JV, the project’s construction manager at risk, sub-contracted with the Atkinson/Technique JV to operate the TBM and will oversee construction of various intake and pumping shafts as well as final lining operations. The project is of utmost importance for the City of Atlanta, explained Bob Huie, Sr. Project Manager for the PC/Russell JV. “Right now, the downtown area’s emergency water supply is approximately three days. With the tunnel the supply will increase to between 30 and 90 days. To be a part of the city’s emergency water supply solution is huge. This tunnel will protect the city for a very long time.”
With the tunnel on the fast track, swift TBM assembly was key. The OFTA process involved coordination by multiple
crews at the large quarry site. “The OFTA went very well. The overall assembly process was well organized and supervised by the Atkinson/Technique JV and Robbins. We had a good team of folks to put it all together,” said Huie. He continued: “This is a unique job where there’s a lot of people with a variety of backgrounds, but everyone came together to make the OFTA happen.”
The Robbins TBM is now excavating in granite, with at least 300 m (1,000 ft) of zones in three separate areas that will require continuous probing. In a section directly below an existing reservoir, monitoring will be particularly crucial to ensure no water inflows occur. The Robbins machine will also be required to negotiate several curves: “We have one curve in the first 300 m (1,000 ft) and the main 370 m (1,200 ft) radius curve is 1,800 m (6,000 ft) in. We plan to do short TBM strokes in this section—about 20 cm (8 inches) to 30 cm (1 ft) shorter than normal to get through the curves,” said Larry Weslowski, Tunneling Superintendent for the PC/Russell JV.
Excavation is scheduled to be completed in the first quarter of 2018. After final lining, the tunnel will be filled with 
water and the quarry site will become Atlanta’s largest reservoir and park, totaling hundreds of acres. While the park site is a bonus for residents, the water storage capacity it will provide is critical. Nearly 1.2 million customers, including 200,000 passengers who pass through the world’s busiest airport every day, count on the water supply each time they turn on the tap. “If the city were to lose water supply for a day, the estimated economic impact would be at least USD $100 million per day. If you consider that this is a USD $300 million project, that seems a pretty good investment in comparison to what could happen,” said Huie.

The Annual International No-Dig Conference is the flagship of ISTT’s education and training effort. The 34th 
International No-Dig Conference & Exhibition was held in October in Beijing, China at the National Agriculture Exhibition Center. The Center is a state-of-the-art facility located in the heart of Beijing.
The China Society for Trenchless Technology hosted the conference. Mr. Wang Fuming, Chairman of the China Society stated, “Beijing, the capital of the People’s Republic of China, is a vibrant, dynamic city with a rich history and may attractions. Beijing is not only a must-see place to visit, it is also a key center of trenchless activity in China. Many major trenchless and underground construction companies are headquartered in Beijing. Trenchless also has played a significant role in meeting the challenges of underground construction in a heavily urbanized area with minimum social and economic impact and disruption.”
During the conference, ISTT held their annual board meeting where Dr. Samuel Ariaratnam, the past chairman of 
ISTT, completed his tenure and Mr. Enrico Boi became the chairman, along with Mr. Jari Kaukonen as vice chairman. Mr. Enrico Boi is from the NASTT (North American Society) and Mr. Jari Kaukonen is from FiSTT (Finnish Society).

PELLA, Iowa — Vermeer has created a partnership with the Des Moines Area Community College (DMACC) — 
Iowa’s largest two-year college serving more than 75,000 students — to certify the Vermeer HDD CircuitSM training program. Individuals who complete the two-week, instructor-led program will be classified as a certified horizontal directional drill (HDD) operator.
“Vermeer and DMACC are particularly excited about the potential benefits to our growing veteran population,” commented Rob Denson, president of DMACC. “The fact that the HDD Circuit training program is a certified addition to the DMACC curriculum offerings means that veterans can use their GI Bill benefits to cover the cost of the HDD Circuit program tuition and lodging to attend the two-week instructor-led program that provides a mix of classroom time with hands-on experience in a small-group learning environment.”
“DMACC has worked with Vermeer on a number of training initiatives focused on building the pipeline of skilled workers for its operations, but this is the most far-reaching effort to date,” said Denson. “Instead of training people to work at Vermeer, this innovative program is training individuals to work in the HDD industry, with skills that can be applied anywhere in the country or the world. These are high skilled jobs that provide outstanding career opportunities for individuals willing to train. DMACC is very proud to be able to certify this program.”
“This is the first-of-its-kind certified HDD operator training program in the nation,” said Dave Wisniewski, vice president, Underground products at Vermeer. “While other training programs may provide a certificate of completion, each student who successfully completes the Vermeer HDD Circuit training program will be certified as an HDD operator from an accredited college. This is important as more project owners are asking underground contractors to verify their HDD operators have received training.”
Vermeer HDD Circuit program will be taught by Vermeer trainers with extensive experience in horizontal directional drilling operation.
During each two-week course, students will be exposed to topics on HDD safety, jobsite evaluation and setup, drill operation best practices, underground utility locating and potholing best practices, drilling fluid mixing and testing, proper bore and pullback techniques including the development of a bore to plan, as well as basic drill maintenance and inspection. Students will get approximately 40 hours of classroom time and 40 hours of hands-on experience — 20 hours locating and 20 hours operating the drill in the field.
“The HDD Circuit program develops drillers who can walk a bore, plan a bore, set up a bore and complete a bore,” said Tony Bokhoven, Lifecycle training manager at Vermeer. “We are creating an opportunity for a new generation of drill operators to have a career in a growing global industry. At a time when the horizontal directional drilling industry is experiencing a shortage of drill operators, the HDD Circuit program is an ideal training program to help veterans, students and others looking for a way to enter this growing industry.”
The goal of the training program is that each student who successfully completes the program will be a productive drill operator or crew member. HDD Circuit program students must complete and pass a written test and hands-on evaluation in order to complete the program and receive the certified HDD operator designation.
