A vertical curve alignment has the first tangent as +4% and second tangent as +1%.if the elevation of the point of intersection is 203.25m, the chainage of end of vertical curve (EVC) is 1024.05m and desirable stopping sight distance is 225m, estimate the elevation of a) Beginning of curve b) Point of chainage 898m e) EVC (Use hi = 1.05 and h2 = 0.26 m)
