Terracon Supports Students at Greater Kansas City Science and Engineering Fair

KC-Science-FairWhen the 63rd Annual Greater Kansas City Science and Engineering Fair took place at Kansas City’s historic Union Station in March, Terracon was there supporting students. The annual fair is by Science Pioneers, a non-profit group whose mission is to create innovative and supportive education activities that will encourage the youth of Kansas City to understand and use science and critical thinking in their careers and everyday lives.

The Terracon Foundation sponsored an academic award: the Senior Environmental Sciences/ Renewable Energy Award. The first place winner was Katherine Calhoun, a senior at Shawnee Mission West High School. Triton Wolfe, a senior at Olathe North High School, won second place. Joe Marsh, P.E., director of Employee Development and Wellbeing, represented the Terracon Foundation during the Awards Ceremony. Both students received scholarships.

“Talking with students at the fair and seeing what they can do was inspiring and worthwhile,\” said Joe. “It was an honor to support these talented young people.”

Two Lenexa staff members, Brett Larsen, P.E., senior geotechnical engineer, and Angela Caw, project manager, attended a “thank you” luncheon hosted by Science Pioneers for Terracon the day after the fair. They had the opportunity to talk with Science Pioneers staff and to view the students’ presentation boards.

“The students’ research was very impressive,” said Brett. “Frankly, a lot of it was more complicated than the work I did as a graduate student in engineering.”

The Greater Kansas City Science and Engineering Fair is the largest in the region. More than 1,300 students, in grades four through twelve, from across the Kansas City metro took part.

Do Constructions Workers Climb Like Spider-Man?

spidermanTerracon experts make presentations to a variety of audiences every day. But Peter Adams, a steel inspector from the Des Moines office, might be the only one who has ever had to field a question about superheroes in the construction industry.

“Do you climb steel like Spider-Man?” His audience members want to know.

His audience is comprised of underprivileged or at-risk preschoolers -“ some with special needs -“ and Peter gets to enjoy answering questions like these as part of his annual visit to Des Moines Public Schools’ Head Start program. For the past 12 years, he has been visiting this Head Start class, which wife, Natalie Adams, teaches. His visit is a favorite part of a unit on the construction industry that is part of the curriculum every year.

Peter always has fun talking to these young children and hearing what they have to say, but there is a serious side to this as well.

“It is important to support our community and help kids who come from poverty and are at risk for learning problems,” said Peter. “And maybe I can inspire a child to take an interest in this field.”

During his talks, Peter touches on many important topics. He teaches them that being safe is an important part of a construction worker’s job, and that to be a construction worker, you must learn how to read, measure, do math, and follow rules to make sure that buildings are constructed well.

“A lot of these children don’t get the opportunity to see things like this first hand, so it’s important to bring visitors into the classroom to inspire them,” said Peter.

He has a well-planned visit that involves passing around items like concrete, steel, certain tools and safety gear, rebar that is shaped like letters, and by having them try to lift a concrete cylinder with rebar inside. This usually gets them to ask questions.

“Peter’s passion for his job and these children is very special,” said Natalie. “He relates very well to them, which is evident by the smiles and the amazed looks on their faces.  I am so thankful that he works for a company which allows him to take time out of his day to enhance the learning of these special children.”

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!
