HEO 1070 - Introduction to Earthmoving and Gradng
Clock Hours: 46
Delivery Mode
on-ground
Course Description:
One of the main purposes of heavy equipment operations is moving earth to excavate, fill, and shape the land surface. In this module you will receive an overview of the various aspects of earthmoving operations. These include the planning and safety measures involved, typical equipment used, grading methods, worksite practices, and soil properties and stabilization.
Heavy equipment operators are often involved in moving earth to level the ground in preparation for planned construction. The proper completion of this phase is essential for the ultimate stability of the final structure or road. Project engineers coordinate the work of surveyors and equipment operators to establish the required land surface, cutting high areas and filling low areas as needed. In this module, you will receive an introduction to the surveying and civil-engineering methods involved in changing the lay of the land’s surface as part of a construction project.
