David Agan
Bureau of Reclamation

How did you get started in the trenchless industry? By happenstance I got my start when moving from the East coast to Denver to work for Kilduff Underground Engineering. Todd Kilduff is a great mentor and proponent for the trenchless industry! During my initial interview, I had the opportunity to tour several trenchless projects, and it reinforced my desire to be involved in this field. Trenchless (new installations) projects involve all the cool and exciting aspects of geotechnical design – like ground behavior and classification, dewatering, support of excavation, ground treatment, risk evaluation, and horizontal excavation – often all in one project! By its nature trenchless is very interdisciplinary and getting to work with people in different areas of expertise really expands your knowledge base.

What career advice would you give to a young person? Don’t be afraid to ask questions. Questions have potential to present different perspectives, open dialogue, show you’re engaged and interested and most importantly allow for the continuation of learning.

John Altinyurek
Kilduff Underground Engineering

How did you get started in the trenchless industry? My first introduction to trenchless technologies was thanks to my former manager at WSP, David I. Smith. He had asked me work on a project at DC, and the uniqueness of the concept immediately grabbed my attention. Later I had a chance to get involved heavily with microtunnels on the Bay Park project and realized that trenchless is the future of the underground construction industry.

How do you explain what you do to someone who has no idea what trenchless technology is? I usually ask them: “Have you ever had to change your way because the road was closed due to the road being half open? Trenchless avoids doing that.”

Who inspires you and why? My wife. She is always there when I need her. Unbelievable.

Daniel McManus
Stantec

How did you get started in the trenchless industry? I was working with Stantec as an intern in Walnut Creek, CA where I began to learn about trenchless methods and geotechnical investigations. During this time, I was able to work with and by mentored by an excellent group of engineers who I truly credit everything I know now to.

The best workday I ever had was … finding out that we were working on a project to improve the water supply in my hometown. It was a very wholesome experience to explain to my friends and family what I do and how the project we are working on will help secure the water supply in our town. Short deadlines can make it easy to have tunnel vision and only focus on the tasks you are assigned for a project. Hearing about this project taking place where I grew up is a constant reminder to me to put myself in the shoes of someone in that community to help better understand the impact of the decisions we make on every project in every community.

Bryce Carson
Bond Civil & Utility Construction, Inc.

How did you get started in the trenchless industry? I grew up in this industry. I started working on my first drill crew while still in school and I have been hooked ever since.

How do you explain what you do to someone who has no idea what trenchless technology is? We install pipes for underground utilities anywhere that it is not possible to simply dig a trench from the surface, typically under obstacles such as rivers, railroads or highways.  

What career advice would you give to a young person? To know what you know and what you do not know – that is true knowledge.

Share a challenge you overcame and what motivated you to push through? July of 2023, I joined a new company, Bond Civil & Utility, in order to start up a new Trenchless Division. Every day since has been full of challenges, but having the opportunity to directly shape the business is extremely motivating.

Amin Tehrani
North Texas Municipal Water District

How did you get started in the trenchless industry? My first exposure to Trenchless Technology occurred during my PhD studies, when I had the opportunity to work with Dr. Mo Najafi and Dr. Ellie Kohankar at the University of Texas at Arlington. This experience opened a new door for me in the field of civil engineering. I was fascinated by how innovative and beneficial trenchless technology methods are in overcoming the challenges of pipeline installation and maintenance.

Who inspires you and why? In the trenchless technology industry, there are many people who inspire me, but one person who stands out is Chris Macey. He received the NASTT Hall of Fame Award in 2018 during the No-Dig Show in Chicago, which was also my first No-Dig event. I had the privilege of speaking with him right after he received the award, and over the years, I’ve had the opportunity to work with him on various committees. What has always impressed me about Chris is his incredible modesty and down-to-earth nature. Despite his many achievements, he remains humble and approachable, which I find truly inspiring

What career advice would you give to a young person? Do not to be afraid of making mistakes. Mistakes are an essential part of learning and growth. Don’t be discouraged if things don’t work out perfectly the first time. Instead, see it as an opportunity to try different approaches and learn from the experience. The key is to keep experimenting, be curious, and keep searching for the right solution. The most important thing is to stay persistent and never stop learning.

Christopher C. Macey, Global Technical Practice Leader, AECOM, Winnipeg, MB

Bo Pajic, Program Manager, Capital Works Delivery, Toronto Water Division, Toronto, Canada

Kristy Gibson, Program Manager, Capital Works Delivery, Toronto Water Division, Toronto, Canada

 

About the Authors. The team that put together this year’s winning paper for rehabilitation is comprised of experts with the experience necessary to tackle an emergency situation during the COVID crisis. Kristy Gibson is a Senior Project Manager with the City of Toronto, where she has managed both linear and vertical infrastructure upgrade projects for Toronto Water since 2015. Bo Pajic is a professional engineer and has been with Toronto Water since 2010 and took the lead in developing the City-Wide planned Sewer Rehabilitation Program in 2015. Chris Macey, P. Eng. is a Vice President and the Americas and Global Technical Practice Leader for AECOM for Condition Assessment and Rehabilitation of Underground Infrastructure with more than 45 years of experience. 

“This project is important to showcase to the industry given its complexity and urgency, especially the Highland Creek site due to its proximity to the Scarborough Hospital,“ Pajic noted. “Trenchless methods allowed the repairs to be completed in a more expeditious manner when compared to open-cut replacement, which was critical during COVID.” Macey agrees. “This work was particularly critical and getting it done and getting the message out there means a great deal.” The City staff were also an important part of the team especially Richard Noehammer, William Shea, Garry Boychuk, Adam Zietara, Jian Lei, George Roknic, Irina Vasile. and Sarah Duff. Pajic and Gibson were thrilled to work alongside Macey, who In 2019 was elected to the NASTT Hall of Fame for his work in Condition Assessment and Rehabilitation. “We would like to thank Chris Macey for his steadfast contributions to the City of Toronto’s Sewer Rehabilitation Program,” they said.”As a leading industry expert, his knowledge and expertise on the Program and specifically in the completion of this emergency project was invaluable.”

Abstract. The East Don River Trunk Sewer (EDTS) and the Highland Creek Interceptor (HCI) Sewers are both critical sanitary sewers in designated ravine areas in Toronto, ON. Both sewers were originally constructed in the 1950’s and during the course of 2020 and 2021, they developed surficial sinkholes due to severe loss of ground into defects in the pipe and manhole structures.

The EDTS was a 1200 mm (48”) diameter pipe in very soft soils and the settlement had engaged 12 pipes with a maximum settlement of about 600 mm (2 feet). Its failure would have resulted in the direct discharge of large sewer volumes in the East Don River. The adjacent section had previously failed and showed signs of active deterioration as well due to loss of ground.

The HCI sinkhole was centered over a Maintenance Hole (MH) that was 9 m (30 feet) deep and had engaged 2 -900 mm (36”) pipes and approximately 4 – 1050 mm pipes (42”). The maximum amount of pipe settlement was about 400 mm (16”). Its failure would have engaged a bridge structure and would also have resulted in large sewage flows into the adjacent Highland Creek.

This paper captures the two separate emergency response efforts in 2021 and early 2022, where both locations were uniquely repaired using a balance of external ground stabilization techniques and CIPP lining with minimal ground disturbance. The HCI repair included MH lining and a single tapered CIPP tube shot with 4 different design sections (varying wall thickness and tube circumference).
