Mr. Denis Pellerin’s role will be to develop CCI’s Engineering and EPC capabilities outside the North American market. He will be based out of Paris, France. Denis Pellerin is a Civil Engineer from Ecole Nationale des Ponts et Chaussées (1983) and has received his MBA from INSEAD (1990). He has 35 years of experience in the trenchless crossings industry.
In 1985, he joined the start-up company, HDI, as a field engineer. HDI became one of the world’s foremost HDD contractors, introducing Horizontal Directional Drilling into Europe, Australia and several countries in Africa, South East Asia and South America. During those pioneering years, Denis and his HDI colleagues introduced new HDD techniques, such as buoyancy control systems for large diameter pipelines, entry casings for pilot holes and gravel shield reamers.
After serving as Site Engineer, Project Manager, Operations Manager and Commercial Manager, Denis was appointed Managing Director of HDI SA in 1991. Throughout his career, Denis has implemented Horizontal Directional Drilling, Direct Pipe®, Microtunneling, Pipe Ramming and Auger Drilling
technologies, sometimes combining technics in order to gain optimal efficiency.
His career with HDI has taken him on more than 2200 trenchless crossings projects, spanning more than 40 different countries worldwide, all safely concluded. Together with HDI, Denis received several industry recognitions, in Australia (1987), USA (1999), Europe (2011) and France (2012, 2015 and 2018), for innovative HDD projects onshore, as well as marine based. He was a founding member and the first treasurer of the professional organization DCA Europe in 1994 and served as its Vice-President from 2008 to 2016.
The CCI Group of Companies are pleased to have Denis join their team.

In the trenchless excavation, horizontal directional drilling, and underground manufacturing industries, one family stands out as leaders in this close-knit community: The Barberas. Family Patriarch, James S. Barbera founded Barbco, Incorporated, a world class capital equipment manufacturer in these industries. In fact, his status is so renown and legendary, that in April, he will be posthumously inducted as a member of the Class of 2020 into the North America Society for Trenchless Technology’s Hall of Fame, joining a very elite and highly esteemed society of industry ground breakers. James S. Barbera has passed the torch onto his three sons, Anthony, David, and James A., who now own the family business, Barbco. The Barbera clan continues to drive the industry forward and now have brought the third generation of the family into this exciting field.
On January 2nd, grandsons Drake Barbera (son of Anthony) and James V. Barbera (son of James A.) along with co-owner Clay Gillian successfully completed their very first horizontal bore with their new company AccuLine Underground at an urban work site in Metuchen, New Jersey. AccuLine partnered with project General Contractor J. Fletcher Creamer & Son, Inc. to complete a 250 foot long crossing that was at a depth of 20 feet under the length of a busy city road skillfully avoiding numerous very critical city main utilities. To say that this 3,000 man hour project was challenging is a complete understatement.
The AccuLine team’s years of experience and deep knowledge of the industry was readily apparent before the first shovelful of dirt was removed from the job site. In his initial meeting with the job owners, Drake made a strong and convincing counter-proposal to the microtunneling option with his recommended approach using a conventional auger boring machine pushing a BMTA (boring machine tunnel attachment). Drake’s proposal proved to the winning combination, securing AccuLine this very prestigious and highly visible contract.
The crew faced numerous job site challenges ranging from old and forgotten infrastructure to rocky and sandy soils. Their expertise allowed them to make on site equipment modifications and adjustments coupled with some new to the field innovations to keep the job on line and on grade, dramatically saving the job owners both time and money. This highly successful initial foray into the Barbera family business as proven that the third generation of Barberas and their company, AccuLine Underground is a force to be reckoned with! Grandfather Barbera must be very proudly watching over his progeny!

Adaptable machine will begin bore at 11.6 m then size down to 9.9 m
In December 2019, the City of Dallas, Texas, USA unveiled the largest hard rock TBM ever to bore in the U.S. The 11.6 m (38.1 ft) diameter Robbins Main Beam TBM will excavate the 8 km (5 mi) Mill Creek Drainage Relief tunnel, and its size is not its only distinction. The adaptable machine will change size partway through the bore, to a more compact 9.9 m (32.5 ft).
The unique Robbins TBM will be used to dig a tunnel designed to provide 100-year flood protection for east and southeast Dallas, areas affected in recent years by severe storms. The tunnel will protect 2,200 commercial and residential properties, including Baylor Medical Center. The current drainage system in these areas was constructed 50 to 70 years ago, and only provides two to five years of flood protection. “The completion of the TBM assembly marks a major milestone in the Mill Creek Tunnel Project,” said Council Member Lee Kleinman, chair of the Transportation and Infrastructure Committee for the City of Dallas. “I’m thrilled to see this type of engineering marvel happening right here in Dallas.”
The dual-diameter aspect of the Robbins TBM will be a first-of-its-kind conversion process. The contractor, Southland/Mole Joint Venture (SMJV), will make the conversion underground about 2.8 km (1.8 mi) into the bore. The two diameters are needed as the upstream section of the tunnel is designed with a circular cross section and peak flow rate of 42 m3/sec (15,000 ft3/sec), while the downstream 2.8 km (1.8 mi) portion has a higher peak flow of 565 m3/sec (20,000 ft3/sec) and was initially designed as a horseshoe cross section. Using the TBM for the entire tunnel is less time consuming and costly. “Robbins and SMJV are working closely to create the safest and most efficient sequence for completing this conversion within the limits of the bore. The City of Dallas (Owner) and our Project Team are very excited to embark on this unique challenge,” said Nick Jencopale, Project Manager for Southland Holdings.
The Robbins TBM, named “Big Tex” with permission of the State Fair of Texas, has been designed with a specialized cutterhead including removable spacers and adjustable bucket lips to convert to a smaller diameter. The TBM will first complete its 11.6 m (38.1 ft) diameter section of the alignment, then back up about 21 m (75 ft) to a transition area for the conversion, which is expected to take six to eight weeks.
As the TBM bores, it will pass through Austin Chalk between 12 to 30 MPa (1,800 to 4,400 at depths from 31 to 46 m (100 to 150 ft) below the city. The route is potentially gassy, so probe drilling is mandatory throughout the project. Crews will utilize ground support including eight 3.9 m (13 ft) long rock bolts every 1.5m (5 ft) with wire mesh and channel straps as needed. The finished tunnel will be lined with a 380 mm (15 in) thick cast-in-place concrete lining.
“Big Tex will work 24 hours a day to excavate the tunnel with crews ranging in size depending on activities,” said Rachel Sackett, marketing and communications director for Southland Holdings. Based on previous work through similar geology, the project team expects TBM excavation to progress rapidly to an average of 25m (80 ft) per day, allowing the project to be completed on schedule in 2023.
