Earthwork I [0:06]

Earthwork involves the measurement of volumes (cut and fill), haulage, and other concepts of volumes of soil determined by comparing the finished grade of a design with the surveyed terrain before the work begins. Many times, it also involves determining the most economical path to achieving a design for a project. Earthwork can be applied to strip projects such as highways as well as broad projects for shopping centers, subdivisions, and the like. In this free course, we end with a description of how volumes are calculated using cross-sections. See the description for the extended version for the additional discussion which includes some typical cross-section data and how it is interpreted. Running time 6 minutes.
