# Elevation Point of Vertical Curve on Road Calculation

The elevation point in a geographic location is the height above or below a fixed reference point. It is most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. Given here is an online civil engineering calculator to perform elevation point of vertical curve on road calculation using the given values of length of the curve (x), initial grade (g1), final grade (g2), and initial elevation (epvc).

### Example:

Calculate the elevation point of vertical curve given that,

Length of Curve (x) = 8

Initial Grade (g1) = 5

Final Grade (g2) = 9

Initial Elevation (epvc) = 4

#### Solution:

Elevation Point Of Vertical Curve = 4 + 5 x 8 + [ (9 − 5) × 8^² / 2 x 8 ]

= 4.5600
