Frequently Asked Questions

What is the use of a leveling rod(grading rod) in surveying?

A leveling rod, also known as a leveling staff or a grading rod, is used with an optical instrument, such as a transit or a theodolite, to determine the differences in elevation.

Why should a leveling rod(grading rod) be used to determine elevations?

Because of its graduations and telescoping feature, a leveling rod allows surveyors to determine the elevation or measure the vertical distance between two horizontal planes. Leveling instruments with telescopes and crosshairs are used to sight the leveling rods’ graduations.

How do you read a leveling rod(grading rod)?

For leveling rods with imperial graduations:

  • Feet - marked in red
  • Inches or tenths of a foot - marked by small black numbers
  • Eighths of inches or hundredths of a foot - indicated by small marks between the numbers

For leveling rods with metric graduations:

  • Tenths of meters - marked by huge numbers
  • Centimeters - marked by squares, lines, or spaces

How do I use a leveling rod(grading rod)?

Place the leveling rod on the elevation point and position its front toward the benchmark location. Then, plumb the rod using its circular level. If it doesn’t have a circular level, align it with the vertical crosshair of the optical instrument. Hold the rod steady until the measurements are made.

How long is a leveling rod(grading rod)?

Leveling rods come in varying extended heights, ranging from 8 to 25 feet.

Leveling Rods

In surveying, determining the elevations or differences in heights can significantly help when leveling, establishing grades, or excavating. This task often requires leveling instruments. However, measuring elevations can’t be done with leveling instruments alone⁠—surveyors also need a leveling rod to use with these instruments. These leveling rods feature graduations to easily measure the differences of elevations. Some leveling rods have powder coatings to protect their graduations against the harsh elements in outdoor settings, while others have graduations that are engraved by laser beams. There are also leveling rods that feature integrated bubble levels so that measuring can be done accurately.

For readability and visibility, some have self-illuminating features to light up their graduations as well as their bubble levels, suitable in low light conditions. Since leveling rods are mostly used outdoors, they are designed to be durable and waterproof, so there’s no need to worry about them getting damaged in tough field conditions. With leveling rods of varying lengths and features here on Engineer Warehouse, you can choose one that can help you measure elevations conveniently.
