In unequal crest vertical curve, a grade (gl of +3 % intersects g2 of-2.4%) at a
vertex (PI) whose elevation is 405.38m and (PC) Station is (16+00). A 700m vertical
curve is to be extended back from the vertex, and a 500m vertical curve forward to
closely fit ground conditions. Compute and tabulate the curve for stakeout at full (100m)
stations.
