What Is a Grade Rod?
Grade rods are an instrument used by construction workers, land surveyors, building contractors, plumbers, and other
professionals who need to take accurate measurements of grade elevation. Leveling rods can be used alongside laser
levels, opticals, and surveyors for optimal precision. They can be made from a variety of materials, but the most
common are fiberglass, wood, and plastic.
How Do I Use a Grade Rod?
Extend the grade rod to its full length along with a transit or auto level. Start with the measurement points you
need, and then have the rodperson (person holding the leveling rod) hold the rod in a vertical position.
Focus the instrument on the grade rod and have the rodman record the measurement.
Why Are Grade Rods Measured in Tenths?
Survey rods that have feet, tenths, and hundredths measurements are known as “engineer’s rods.”
Since they use decimals, this makes it easier for engineers to do calculations that are easily converted.
