The Grading Level I course is designed to give participants the skills and knowledge required to become a competent grade and drain inspector. Topics discussed include soil sampling, interpretation of soil profile sheets, moisture and density testing by the nuclear method, developing moisture density target values by the one-point proctor method, visual identification of soil types, and specifications of grade, pipe installation, and drain construction. Each participant will perform a one-point proctor and a nuclear density test.
Qualification is good for five years.
