Erin Marek 11/14/07 CE 301 Lab 9 Topographic Surveying, Cross-Section Leveling Introduction: The purpose of this lab was to measure the elevation of an area of a proposed building site. It was also helpful in teaching me to become more familiar with the dumpy level and its many uses in civil engineering and elevation measuring. Procedure: The class should divide into teams with about three people per team to conduct the lab independent of each other. Each team needs a level rod and a dumpy level. First the dumpy level should be set up and leveled somewhere in between the 0 and 50 feet east points. One member needs to stand at each point to be leveled as the others use the dumpy level to measure the elevation. The elevation of points 0N, 25N, 50N, and 75N should be measured as the IS on the 0 foot row. The last point on this row, 100N, should be measured and recorded from the same set-up as the FS. The BS elevation of point A should be recorded from this set-up as well.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
