Earthwork involves measurement of soil volumes and sometimes other concepts like haulage, all determined by computing by differencing the existing terrain with design surfaces. This is done in many ways. In this course, the emphasis is on how cross-sections are used to determine those volumes. There is also an introduction to the concepts of swell, shrinkage, and construction soil classification. Running Time 28 Minutes.

You will learn…
• Various applications of earthwork in the construction process
• Some considerations when surveyors are tasked with determining soil volumes that depend on project types, terrain, and various technologies and methodologies
• Cross-section methodology, discussing field and office procedures
• What shrinkage and swell means
• A brief introduction to the methods of construction soil classification
