Situation 3] The bearing of the first tangent of a simple curve is N70.8°E while the second tangent has a bearing of S82°31'E. The degree of curve is 4.5° and chainage of PC is 3+801. It is proposed to decrease the central angle by an angle of 7° by changing the direction of the second tangent, in such a way that the position of PT and the direction of the first tangent shall remain unchanged. Determine the following: i. New angle of intersection, I'. ii. New radius of the curve, R'. ii. New chainage of station PC. 4:37 PM

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.
