Why Dirt Matters
Most people don’t think twice about roads, bridges or tunnels; at least not about how the structures were built or the materials that were used to construct them. And most people certainly don’t think about dirt or give dirt the credit it deserves. Dirt matters – everything around us is supported by dirt, soil or rock.
The Transportation Corridor Agencies (TCA) is celebrating National Engineers Week (Feb. 21 – 27) by recognizing its engineering team on Facebook and celebrating how engineers make a difference in our communities. Paul Bopp and Juliet Su, both engineering managers at TCA, recently participated in the 2nd annual Girl’s Engineering Day – Transporting the Future – at Dale Junior High School in Anaheim.
Hosted by WTS Orange County, an organization dedicated to the professional advancement of women in transportation; Transportation YOU, an interactive mentoring program that offers young girls ages 13-18 an introduction to a wide variety of transportation careers; and the Anaheim Unified School District, more than 100 young women, grades 7 to 12, from 16 schools participated in a fun and informative day introducing them to engineering and engineering-related fields.
Paul and Juliet led the Geotechnical Engineering station, providing an overview of why dirt matters; why foundations are critical to transportation projects; and how to select the best foundation to match the project soil conditions. Geotechnical engineering is a branch of civil engineering that deals with soil and rock and their relation to the design, construction and operation of engineering projects. Nearly all civil engineering projects, including roads, bridges and tunnels, must be supported by the ground and require geotechnical engineering. In short, dirt matters – for our future and growth of infrastructure.
Students used wood blocks and sticks to serve as foundations and pile supports in trays of sand and clay to compare how foundations behave with and without pile supports in each type of soil.
“It was incredibly rewarding to participate in Girls Engineering Day,” said Juliet Su. “In an industry where men largely outnumber women, it’s a wonderful opportunity to introduce the world of engineering and shape the mind, goals, and future of a young woman.”
Everything around us is supported by dirt, soil or rock and geotechnical engineers are responsible for ensuring that. Paul and Juliet’s hope is that these students become our next generation of civil engineers; but for now we’ll never doubt dirt’s importance – or look at a road, bridge or tunnel the same way.
