A falling gradient of 2.5% meets a rising gradient of 3.2% at a reduced level of 235.60 m and a through chainage of 1172.45 m. A parabolic vertical curve having equal tangent lengths is to be used to connect the gradients and the K value for the curve is 26. Calculate (i) The reduced levels of the tangent points (ii) The reduced levels of points on the curve at exact 20 m multiples of through chainage (iii) The through chainage and the reduced level of the lowest point on the curve
