For every infrastructure megaproject, there are as many small, typically unsung but vital components as there are large, more newsworthy sections. Yet without these smaller components, the overall project may not be able to proceed. The District of Columbia Water and Sewer Authority’s (DC Water’s) Clean Rivers Project is no exception. When three critical utilities above three separate areas along the Anacostia River Tunnel alignment were identified as being vulnerable to settlement during tunneling operations, Moretrench was contracted to perform compensation grouting though pre-placed sleeve port pipes to mitigate the potential for lost soil volume.

Working with local area organizations is very much a part of Moretrench’s corporate culture, and this extends to area schools as well as non-profit facilities. Over the past year, Shop Manager Craig Sofio and HR Generalist Joanne Muccione have been instrumental in giving presentations, arranging a tour of the company’s facilities and shop, and initiating a Share Time program for students at the Morris County School of Technology (MCST). They were invited to join the school’s Carpentry Advisory Board in December, 2016, and were recognized with a High Impact Partner award at the school’s Spring Advisory Dinner held on June 6th. Mr. Sofio, himself a graduate of the school, was a keynote speaker at the Class of 2017 Commencement ceremony on June 16th, 2017.
From more than 30 applicants, three students were selected for the company’s first Share Time program, overseen by Mr. Sofio. They work alongside shop personnel for half a day, four days per week obtaining real life experience in aspects related to their vocational studies focus. “It’s an honor and a privilege to be associated with MCST,” said Sofio. “The Share Time began in January and is proving to be extremely successful. I give credit to Joanne Muccione who has been a driving force behind these initiatives. We both look forward to continuing our relationship with the school for years to come.”
The Lower Hudson Valley Branch of the American Society of Engineers has selected Moretrench’s Old Croton Trailway Project to be the recipient of the 2017 Ward House Award for Small Project of the Year. This award is presented for a minor and complex civil engineering project in the Lower Hudson Valley and is named after the Ward House in Rye Brook, New York, which has been designated by ASCE and the American Concrete Institute as a National Historic Civil Engineering Landmark. Selection of the award is made by the Lower Hudson Valley Branch Board. The Old Croton project came out ahead of the other projects considered based on a number of factors including complexity, design, and overall success.
The job itself involved replacement of a failed 185-year-old masonry brick retaining wall supporting the landmarked Old Croton Aqueduct. The failure caused a significant landslide. Challenges involved with installing the permanent soldier pile and concrete lagging replacement wall included a fast-track schedule, extremely tight access, and constructability of the new wall on a steeply sloping and unstable site.

“Dewatering is often misunderstood or neglected until the last possible moment in the life of a project.”
Moretrench’s Chief Dewatering Engineer Greg Landry, P.E., shares “The Secret to Dewatering” in the May/June issue of Deep Foundations. This informative article aims to clear up a pervasive but fundamental misunderstanding about how to determine the amount of dewatering effort required for a project by taking the reader through commonly used dewatering methods and clarifying widely held misconceptions about this often critical part of so many underground construction projects.
