The formula to calculate the Construction Grade is:
\[ \text{Grade} (\%) = \left( \frac{\text{Rise}}{\text{Run}} \right) \times 100 \]
Where:
Construction grade, also known as slope, is the measure of the steepness or incline of a surface. It is typically expressed as a percentage and is calculated by dividing the rise (vertical change) by the run (horizontal distance) and then multiplying by 100. Understanding the grade is crucial for ensuring proper drainage, road safety, and the stability of structures.
Let's consider an example:
Using the formula to calculate the Construction Grade:
\[ \text{Grade} = \left( \frac{10}{50} \right) \times 100 = 20 \, \% \]
This demonstrates that with a vertical change of 10 inches and a horizontal distance of 50 inches, the construction grade would be 20%.
