2018 Summer intern

Civil Engineering major

Anita Zelada is pursuing civil engineering at the University of Oklahoma and interned with Terracon at the OKC office over the summer of 2018, for the Material Internship Program. Her internship experience ranged from material testing in-house and on-site. Anita interned from May to August, and was paid fifteen dollars per hour. Her total number of hours worked was approximately 504.75 over a period of 14 weeks.

Over the summer, Anita had the opportunity to work with the Material Department on highway projects. For such projects, Anita assisted project managers with material testing estimations using industry standards and specifications, such as ASTMs, Project Drawings, etc. Additionally, the intern assisted in soil classification alongside senior and staff engineers during the Highway 40 project. Anita performed In Situ testing, and assisted engineers with the construction of boring logs. Working in the Highway 40 project testing and soil classification, Anita learned different testing requirements for highways in the transportation industry. For example, performing Texas Cone Penetrometer (TCP) tests instead of Split Spoon Test (SPT). As a result, her interest in learning more In Situ testing has resulted in her taking the class in In Situ at the University of Oklahoma this upcoming semester. She will be better prepared, and she has the valuable experience needed for joining the industry.

Finally, Anita has developed business and client development exposure by joining the networking team and participated in networking events. This experience has strengthened her ability to engage and participate in industry current events, and learned how to build viable client relationships through her services as a future engineer.
