My summer internship was only for about a month, but even in that short of a time I learned a lot and worked with some really amazing people! My first major project was to go over the layout of the parking lot for a new dollar general to be built. Let's just say my CAD skills improved tremendously. Aside from the technical, I learned about SALDOs (SubDivision and Land Development Ordinances), HOPs (Highway Occupancy Permints), and the many other ordinances that new construction has to be within the limits of, as well as how to prepare the reports to be submitted for approval.
Though my time there was on the shorter side, I feel like I have a better grasp of what to expect in the real world, and know more about the ordinances and where to find them, as well as gaining plenty of experience using the copier, haha :)
