ECI recently released a new version of its Corporate Safety Manual. Unlike past versions focused on safety compliance, this new version is appropriately named the “ECI Safety Program Manual” to reflect ECI’s view of creating a safe workplace through a holistic approach that focuses on leadership and corporate culture.
As summarized by Kenneth Pidgeon, PE, president of ECI:
“ECI strives to maintain a corporate culture of safe work practices to protect our workers, the public, and the environment.”
The highlights of the Safety Program Manual include:
- Technical training
- Professional behavior
- Project planning
- Risk Assessment
- Standardized safety practices
- Strong communication, documentation, and attention to details.

Akkerman, Inc., a pipe jacking and tunneling equipment manufacturer out of Brownsdale, MN has featured ECI in its 2017 calendar. ECI’s Lebanon Route 120 sewer crossing of I-89 was featured for June with a photo of ECI’s crew lifting the muck cart out of the excavation. The project involved a 48-inch-dia steel casing installed by Akkerman’s TBM.
ECI’s Ryegate Culvert Project was recognized by the Northern New England Concrete Promotion Association for “Cast-in-Place Concrete Structures” at the NNECPA Annual Meeting. We were nominated by Carroll Concrete, an NNECPA member and ready-mix supplier of the concrete for the project.
The culvert project involved over 2,400 cy of concrete, designed for a 100 year service life. The unique complexity was the 32-ft arch span formed and poured using a Doka form system. The 2.5-ft-thick wingwalls reached a height of 27.5 feet above their footings and were accomplished in a single pour each. Reinforcing steel was both uncoated and dual coating, depending upon its location. The headwall and wingwalls were formed using a liner to provide a more aesthetic appearance.
ECI’s Ken Pidgeon co-authored a technical paper with the Marco and Adriane Boscardin. The paper, entitled “Design, Installation, and Testing of Hollow Bar Tiebacks used as Excavation Support” was presented by the lead author, Marco Boscardin, PE, PhD. The paper describes the use of over 700 hollow bar anchors for the 70-ft-deep excavation at the Ryegate Culvert.

DFI 2016 in New York City was attended by over 1,000 engineers, contractors, industry suppliers, and owners involved in the deep foundation industry. Ken has attended several DFI annual conferences throughout the years, including 1994 and 1995 where he authored and presented technical papers.
The waters of the Manchester Brook have been flowing through the new 32-ft-wide Ryegate Culvert since May. And just recently, the temporary bridges for US Route 5 and the Washington County Railroad were removed and traffic was back to the final highway and railroad alignments. The new 32-ft-wide concrete arch, with lengths of 144 and 128 feet and a 50-ft-long open area between them, replaces an old undersized collapsing culvert. The work was completed over a period of nearly 2 years and without closing US Route 5 and with only limited rail shutdowns during non-traffic periods.
ECI self-performed nearly every aspect of this complex heavy civil project including earthwork, foundation and sheet piling, tiebacks and soil nails, temporary bridges, concrete, rail work, paving, horizontal directional drilling, quality control program, and project management.
This project also includes many firsts for ECI:
- ECI’s first design-build (D-B) transportation project – Our client was the Vermont Agency of Transportation. ECI was the first Vermont contractor to serve as a lead for a VTrans D-B project. And, Ryegate was just the 6th D-B project for VTrans.
- ECI’s first and second temporary bridge launches, both of which used the crane-assist method – The 80-ft-long highway bridge was unique for its 7% grade and on a skewed alignment to the excavation which posed challenges during installation and relative to maintenance. The 70-ft-long railroad bridge was also unique because of the limited access to the work site from the rail. ECI deployed the pre-assembled railroad bridge using rail car “trucks” which were incorporated into the launch.
- ECI’s deepest excavation – And, likely the deepest braced excavation in soil ever attempted in Vermont with a final depth of 70 feet below the railroad and 65 feet below US Route 5. The excavation was supported by interlocking steel sheet piles and supplemented with soldier piles and wood lagging in certain areas. ECI installed over 700 tiebacks and soil nails for bracing.
- ECI’s most complex concrete project – The culvert project involved over 2,400 cy of concrete, designed for a 100 year service life. The unique complexity was the 32-ft arch span formed and poured using a Doka form system. The 2.5-ft-thick wingwalls reached a height of 27.5 feet above their footings and were accomplished in a single pour each. Reinforcing steel was both uncoated and dual coating, depending upon its location. The headwall and wingwalls were formed using a liner to provide a more aesthetic appearance.
- ECI’s most complex QA/QC Program – As the design-build contractor, ECI also performed its own field quality control on all aspects of the work. The QA was performed by Greenman-Pederson, a consultant to ECI. The QA/QC aspect of design-build transportation projects are highly involved systematic programs developed and executed by the D-B Team to the standards established by VTrans and FHWA .
- ECI’s first use of an automated robotic total station for monitoring geotechncial settlement points – The system automatically took daily optical survey measurements on prisms mounted on different features of the excavation support system, temporary bridges, embankments, and completed concrete work. The system was set up to provide automatic email reports to ECI if movements exceeded anticipated movement levels.
ECI’s design partners (Dubois & King of Randolph, VT and Boscardin Consulting of Amherst, MA) designed the permanent work. Boscardin Consulting and ECI jointly, with input from GEI Consultants (Winchester, MA), designed the temporary excavation support system. Other D-B Team members included EIV Technical Services as the Environmental Compliance Officer and Francine Perkins as the Public Relations Officer.
