Thursday, June 6th – Grouting/Ground Modification II GROUND FREEZING FOR TUNNELS, SHAFTS AND ADITS By Joseph A. Sopko, Ph.D., P.E. and Adam Curry, P.E.
RETC 2017 is the premier event of the 2017 tunneling and underground construction calendar, featuring more than 21 technical sessions with presentations by leading industry experts, 34,000 square feet of exhibit space, and 190 exhibit booths. Be sure to stop by and visit booth 304, and don’t miss this instructive and informative presentation on Moretrench’s complex and challenging ground freezing project for D.C. Water’s First Street Tunnels.
Moretrench extends a warm welcome to Martin McDermott, P.G., who joins us as a Division Manager for our Geotechnical Group. Mr. McDermott has more than 30 years of geotechnical construction experience, with a particular area of expertise in the field of drilled shaft construction. He holds a Masters degree in Engineering Geology from Drexel, a B.A in Geology from LaSalle, and is a licensed Pennsylvania Professional Geologist. He is a seasoned, goal-oriented and proactive professional and brings a wealth of underground construction knowledge to his new position, particularly in the area of deep foundations.
His primary focus will be the company’s drilled shaft/secant pile wall operations in the Northeast and New England regions. He will be based in our new office in the Philadelphia area, which will also offer the full range of Moretrench’s services.
Mr. McDermott is also actively involved in several professional organizations. He is a former VP and Treasurer of the Association of Drilled Shaft Contractors (ADSC) and previously served on its National Board. He is also a member of The Moles, the Deep Foundations Institute (DFI), the American Society of Civil Engineers (ASCE), and the General Building Contractors Association (GBCA).
“Martin’s drilled shaft experience and his extensive background in geology will be an asset to Moretrench as we continue to grow our business and I look forward to working with him for many years to come. Please join with me in welcoming him to the Moretrench family,” Thomas J. Tuozzolo, P.E., Senior Vice President.
Hard hats that they decorated themselves and souvenir T-shirts were the order of the day for our young visitors, who ranged in age from 4 to 13 years old.
This year’s nationwide “Take our Sons and Daughters to Work” day was held on April 27th and Moretrench’s Rockaway office hosted 25 of our employees’ children for the popular annual event. The full day of activities included a welcome breakfast and presentation by Division Manager Matt DeGregoris, a tour of the offices and shop to see where their parent works, a close-up look at some heavy construction equipment, and keepsake photos with their parent.
The organization’s 2017 theme of ‘Count on Me’ was woven throughout the schedule and included a group activity that saw our young visitors working together to construct a complex popsicle stick maze for Hexbug racing, and time set aside so that they could write or draw a picture about what the theme meant to them. But the highlight of the day for the second year running was undoubtedly the Rizzo’s Reptiles show where everyone had the opportunity to learn about, and safely handle, a variety of small mammals as well as an 8-ft long python named Ariel.
This is the second year that Moretrench has hosted this event. “Once again it was very successful and we look forward to continuing to participate for years to come,” said Joanne Muccione who organized and coordinated the day’s program.
Volunteers who helped with the activities were Magda Nicosia, Beverly Bischer, Michael Fattorusso, Johnna Emanuel, Daniella Santos, Linda Scheck and Doris Zwarych.
Moretrench is pleased to announce that Neil Hancock has recently joined our team as CCR Services Manager. Neil has more than 25 years of business development management experience as well as significant experience in environmental assessment, remediation and brownfields redevelopment. Prior to joining our team, Neil was with Golder Associates Inc. as a Principal and Florida Director of Business Development for over 21 years.
His primary responsibility with Moretrench is to pursue business opportunities and develop sustainable client relationships with respect to the company’s Coal Combustion Residuals (CCR) services, which include ash dewatering and water treatment, dam and levee repair and rehabilitation, and cut-off and containment barriers. He has a B.S. in Geology from the University of Florida and Associate in Science degrees in Oceanographic Technology and Petroleum Technology from the Florida Institute of Technology.
“Neil’s experience and proactive, customer-oriented approach are great assets that will really enhance our ability to reach prospective clients and introduce them to our CCR ash pond services. I welcome him to the team and look forward to working with him for many years to come.”

Given the presence of dense, bouldery glacial till from approximately 20-30 feet below ground surface, permeation grouting was selected for groundwater control to bedrock beneath Posillico’s structural secant pile excavation support for the new 46th Street Vent Plant in New York City. Jet grouting was also used to close gaps around a water main that traversed the excavation. Read about this challenging project, published in this month’s issue of ADSC’s Foundation Drilling magazine, here. 42017 Moretrench_Posillico

This premier 5-day short course covers grouting methods; ground freezing for shafts, tunnels and cross passages; and construction dewatering systems. More than 35 presentations are scheduled covering engineering, equipment, materials and methods, plus off-campus field and on-campus laboratory demonstrations, all by internationally recognized industry experts, makes this a must-attend event for owners, designers, contractors, consultants and suppliers. Take advantage of the many networking opportunities and earn while you learn, with course completion offering 3.5 CEUs.
Moretrench is a regular participant at the event, with three presentations being made this year:
The ADSC mid-Atlantic chapter of the International Association of Foundation Drilling (ADSC) will host a drilled shaft seminar on April 27th, 2017 at the Turf Valley Resort, Ellicott City, MD.
Engineers, contractors, inspectors and anyone interested in the advancement of deep foundations in the mid-Atlantic region will benefit from informative presentations by experts in the field, including Moretrench’s Jon Bennett, P.E. Plan to arrive the day before and enjoy a morning round of golf and an evening welcome reception.
Moretrench’s emergency response capability is second to none, and this was evidenced when the historic Old Croton Aqueduct in Yonkers, NY, was compromised by a significant landslide when a portion of the original retaining wall failed. Moretrench’s Michael Fattorusso and McLaren Engineering’s Thomas Broderick will present an interesting and informative case study on the challenges of installing a replacement retention system at the:
Handling coal ash management and storage procedures in order to keep facilities in compliance with current regulations, as well as adapting to future regulatory changes, is a hot topic in the Coal Combustion Residuals (CCR) community. Moretrench is in the forefront in assisting power companies with closure challenges through the engineered design and installation of pre-drainage systems. These systems have proven to expedite excavation or capping of CCR materials and enhance the safety of the excavation or grading and capping processes.
The recent EUCI Coal Combustion Residuals Conference, held in Atlanta, GA, from March 30-31, showcased the issues facing the power industry and steps currently being taken. A half-day pre-conference workshop led by Moretrench Senior Vice President Paul Schmall and Chief Dewatering Engineer Greg Landry discussed the behavior and responsiveness of ash to drainage methods, the wide range of techniques that can be used, associated water treatment methods, the geotechnical investigations necessary, geotechnical verification and monitoring, and new advances in the technologies. Paul Schmall was also a member of the Closure Services Contracting Panel which engaged in a discussion of “best fit” contracting practices.
“It was an excellent show. A recurring theme was the need for early dewatering. This was driven home by Anita Perry with Southern Company Services who also spoke to the need for in-situ ash monitoring. The concepts are sinking in!” – Paul Schmall
