Terracon plays important role in 120-year-old BNSF Bridge rehabilitation

The 120-year old Bellefontaine railroad bridge spans the Missouri River north of St. Louis and consists of four 440-foot trusses. The open-deck bridge once housed two tracks, but was later reduced to one. In March 2013, BNSF undertook a rehabilitation project on the bridge to enhance its longevity. BNSF called on Terracon to provide health and safety monitoring for its workers during the project. Chris Brewer, P.E., and Jonathan Reber, both from Terracon’s St. Louis office, provided airborne lead, total respirable dust, and noise monitoring. Senior oversight and review was provided by Gary Ganson, CIH, CSP, from Terracon’s Corporate office.

Project completion is planned for November of this year, when crews will use a 60-hour maintenance window to shift the mainline track. The rehabilitated bridge will allow for wider loads to cross the river. The project was highlighted as the cover story for the June 2013 issue of BNSF’s “All Aboard” magazine. BNSF recently requested that Terracon perform similar services for a bridge project in North Dakota. Terracon’s network of professionals, commitment to safety, and ability to provide a consistent client experience regardless of service at multiple locations across the country are just a few reasons why companies like BNSF choose Terracon.

Terracon's Oklahoma City office staff help introduce eighth grade students to the world of biology and engineering

IMAG0097On June 13, 2013 Terracon’s Oklahoma City (OKC) office hosted 25 eighth grade students, and five faculty members, attending Oklahoma State University’s (OSU) summer camp titled, “Biology and Engineering for a Sustainable Tomorrow.” The camp was funded through the State Regents Summer Academy and was aimed at introducing the students to the vast world of biology and engineering as applied in everyday life. Terracon employees were tasked with covering the topic of bioremediation.

Phil Wood, Terracon’s OKC office manager, welcomed the visitors with an introduction to Terracon, a description of the math, science, and engineering behind all that we do, and an encouraging word regarding the dedication to education required to pursue a career in these fields. Members of Terracon’s OKC environmental department then took the students on a tour through the world of environmental consulting!

First, the students witnessed the drilling of a soil boring and installation of a monitoring well by Terracon’s OKC drilling staff. The students aided in classifying soils, gauged the monitoring well, and learned about such topics as groundwater flow, subsurface contamination, plume migration, and contaminant delineation. In the afternoon, they broke into groups and rotated through five stations covering the topics of geology, groundwater flow, injections, bioremediation, and health and safety. Through discussion and hands-on learning, the students discovered the world of rocks and minerals, learned about groundwater quality and field data collection, developed an appreciation for the intricacies of enhanced anaerobic bioremediation, tried on an array of personal protective equipment, and took a stab at creating their own mini-landfarm.

The program was an opportunity for Terracon to reach out to the community, and share with the next generation the importance of math, science, and engineering. The students had a great time at Terracon and the OSU staff is already looking forward to next year’s camp!

Gaboury Honored with Ernst & Young Entrepreneur Of The Year® 2013 Award in Central Midwest

OLATHE, Kan. — Ernst & Young LLP announced David R. Gaboury, P.E., president and CEO of Terracon, a winner of the Ernst & Young Entrepreneur Of The Year® 2013 Award in the Central Midwest at a gala event at the Sheraton in Overland Park, Kan., on Thursday, Jun. 20, 2013.

The award recognizes outstanding high-growth entrepreneurs who demonstrate excellence and success in such areas as innovation, financial performance, and personal commitment to their businesses and communities.

“This is a great honor because it recognized the collective success of our more than 3,000 associates nationwide,” said Gaboury.

Gaboury joined Terracon in 1997 as executive vice president and Chief Operating Officer, and was named president and CEO in 2002. Gaboury has more than 20 years of experience as an engineer with expertise in environmental, geo-environmental, and water resources engineering. He is a graduate of the Harvard School of Business Advanced Management Program and holds a master’s and bachelor’s degree in civil engineering from the Massachusetts Institute of Technology (MIT) and University of Massachusetts at Amherst, respectively.

When Gaboury joined Terracon, the company was a successful Midwest consulting engineering firm. The entrepreneurial opportunity and challenge for him at the time was to increase Terracon’s success and profitably grow the firm to become a national leader in its industry. As an outside hire, Gaboury’s first challenge was to strike a balance between showing appreciation for the firm’s previous successes and bringing in his new ideas and vision. This was accomplished by developing strong relationships within the company and building consensus around the strategic direction of the firm through the development and implementation of clear, concise strategic plans.

The entrepreneurial building blocks that Gaboury used to consistently and profitably grow the firm included building and strengthening Terracon’s existing services while adding adjacent service lines; emphasizing the balance of internal and acquisition growth; building a core competency of identifying, making, and integrating acquisitions; and developing corporate services consisting of best in class corporate functions (e.g., information technology, legal, finance, and accounting, etc.). He also emphasized a concept that Terracon field offices were the “clients of the corporate office” and should be treated as such, through timely response to requests, quality corporate support, and other various other activities that contributed to the success of these offices.

Gaboury has also built a future entrepreneurial strategy for continued success that is outlined in Terracon’s five-year Strategic Plan 2017. The plan includes three key parts that include expanding adjacent service lines related to the company’s core service lines; emphasizing employee safety, wellbeing, and engagement not as a mere business strategy, but based on genuine care and concern for employees and their families; and expanding Terracon’s business presence outside the United States. He also established and regularly emphasizes Terracon’s purpose of “Delivering Success to Employees, Clients, and Communities.”

Gaboury and the nine other winners in the Central Midwest will now go on to compete at the national level. Award winners in several national categories, as well as the National Entrepreneur Of The Year Overall Award winner, will be announced at the annual awards gala in Palm Springs, California, on Nov. 16, 2013.
