Excavation, Trenching and Soil Mechanics

Course Description

This course covers OSHA Standards related to excavation and trenching. Topics include practical soil mechanics and its relationship to the stability of shored and un-shored slopes. Introduction to various types of shoring, soil Classification, and protective systems will be emphasized.

Testing methods are demonstrated and students participate in workshops in the use of instruments such as penetrometers, torvane shears, and engineering rods. Upon course completion students will have the ability to assess employer’s compliance with the OSHA Excavation Standard, utilize soil testing methods to classify soil types, determine protective systems for excavation operations, and training requirements.
