Two tangents converge at an angle 27.4 degrees, which were connected by a reverse curve having common radius. The direction of the second tangent is due to East which is having a shortest distance to the first vertex of 163.04 meters. Station PC is at 10+615.2 and the bearing of the common tangent is S 44.3 E. Compute for the total cost of the curve from PC to PT in pesos. The following are the cost index and specification: Type of Pavement - Item 311 (Portland Cement Concrete Pavement) Number of Lanes-3 Lanes Width of Pavement - 4.0 m per lane Thickness of Pavement 15.1 cm Unit Cost - Php 1,585.93 per cubic meters

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.
