Building Envelope Strategy For a One-of-a-Kind Building Design

Scoobe-constructionWith a unique new design that includes an observatory dome 40 feet above the ground, half of its planetarium dome outside of the building, and multiple exterior cladding systems; some say the building looks like a spaceship.

The original San Antonio College Planetarium opened as part of the Alamo College System in 1961 and has entertained and educated more than 2 million people. The facility was rededicated in 1994 as the Scobee Planetarium to honor NASA astronaut and former San Antonio College student, Francis R. Scobee, who served as commander of the Space Shuttle Challenger’s tragic final flight in 1986. Complete story found here.

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.”
