HEO 2030 - Soils and Site Work
Clock Hours: 90
Delivery Mode
on-ground
Course Description:
This course describes the work involved in preparing a site for excavation and construction. The module first identifies important site safety practices. Other key topics include controlling water on a site, establishing grades, and laying pipe. Further, the course introduces trainees to the various types of soils, their properties, and how these properties affect the heavy equipment operator.
