Over the course of the summer, I was able to work on projects ranging from Oklahoma all the way to the Southern border with Mexico. At the beginning of the summer, I worked alongside the environmental and site civil teams completing small projects across Oklahoma. These included site projects for school additions and environmental research for future planned developments. In the second half of the summer, I switched teams and began working with the bridge team. I worked on a service plaza outside Chandler and was able to experience many aspects of the project. First, I completed quantities calculations for the road team and then was able to work on superstructure calculations for the bridge team. I drafted sheets with Microstation and CAD for the summer. The last project I had the opportunity to assist with was a border wall project on the Rio Grande. It was the first time I encountered government work and had to collaborate with another company outside Olsson.

I worked as a Road and Bridge Intern during the summer of 2018. Working at Olsson was an incredible experience because I got to use the skills and technical knowledge that I have been learning in college in a real-world setting. I also learned a lot about the engineering and design industry that I do not get to learn about in school. As a Road and Bridge Intern, I worked closely with bridge and transportation engineers, and aided them with whatever they needed. One of the most important technical skills that I learned this past summer was how to use ODOT Microstation. Going into my internship, the only drafting program I knew how to operate was AutoCAD, so it was neat to learn a new program. During my time at Olsson, I worked on several projects; however, I mainly focused on the Chandler Service Plaza proposal project. On this project, I helped the bridge engineers design a bridge deck reinforcing for the Service Plaza. I also helped the bridge team prepare and draw the bridge details on AutoCAD Civil 3D and Microstation for the 90% project proposal. One of my favorite parts about working at Olsson was getting to spend a week at the Geotechnical Laboratory. At the lab, I got to run Proctor tests, Atterberg Limits tests, and sieve analyses on different soils. I also aided Daniel Ferrufino with making core logs for the different soil samples. Overall, I had an amazing experience at Olsson. Everyone was extremely nice and helpful, and they gave me plenty of work to do. I looked forward to getting up and going to work every day, and I am extremely grateful for the experience.
