A road is being constructed to link two villages; the contractor has set out the straight sections of the road but needs help connecting the straight ends with a circular curve, a) With start and end points set-out and known, describe the process of setting out the rest of the curve? b) The chainage of the intersection point of two straights is 1200 m, and the angle of deflection is 30°. If radius of a circular curve to be set out is 810 m, calculate, i) The highest most appropriate chord length to be used as peg distance (value should be divisible by 5) ii) Length of the long cord. iii) the chainage at the beginning and end of the curve, iv) Tabulate the data necessary to set out the curve by the tangential method using the total station and a reflector.
