OLH Pipe Slope & Invert Calculator

USE IT FOR QUICK PIPE GRADE CHECKS

Choose the calculation you need.
Enter the known invert elevations, distance, slope, or fall required by that calculation.
Use Find Ending Invert to calculate where the pipe should finish.
Use Find Slope or Find Fall to check the grade between two elevations.
Use Check Intermediate Invert to verify grade at a point along the run.
Review the result before carrying the number farther down the trench.

Note: This tool supports field calculations and checks. Always verify plans, survey control, structure elevations, flow direction, tie-in conditions, and project requirements before relying on a calculated invert.
