You have been asked to determine the bottom of steel elevation for the Cuyahoga Valley National Bridge. (X marks the spot) The surveyors in the field obtained the following data by setting up a total station on a point of known elevation. Use ONLY the APPLICABLE DATA Height of Prism= Height of Surveyor= Height of Total Station= Elevation of known point A= Horizontal distance to prism= Vertical angle to bottom of steel= 4.37 ft. 6.11 ft. 5.75 ft. 1248.86 ft. 122.88 ft. 26°22' 26°22' Bridge

Control Survey and Geodetic reductions

Control surveys or survey controls are used to establish reference points as a basis for various construction activities. Vertical and horizontal control points are to be established in a control survey to increase accuracy. After establishing the control points, all other types of surveys such as topographic, right-of-way, aerial mapping, construction layout, boundary surveys, and utility mapping can be worked upon so that control networks can be formed. The place from which the observations are made is called a survey station.
