During a rough grading phase of a new road construction, you discovered a 25 cm water pipe crossing the roadway at Station 0+555.0. The elevation on top of the pipe is 219.27m. To resolve this problem, the project manager asked you to calculate and layout a vertical curve such that the top of the pavement passes 1 m above the top of the water pipe. Given: Vertical curve beginning at Stat. +495.0, G1-8.75% G2--1.5%., Calculate: Length, PVI Station, Pavement Elev, at the water pipe crossing. The design facts are: Ref. Stat. 0+370.55 Elev. +213.17m. Vertical Curve 1: PVC @ 0-426,56,L - 30 m. G1--2.5%, G2 - +8,75%
