Earthwork Estimating
Students will learn to accurately estimate earthwork construction costs. Using a real set of drawings, students will complete a variety of earthwork take-offs and will apply labor and material costs to each take-off. Students will gain the knowledge and skills needed to produce accurate earthwork estimates using efficient and reliable estimating techniques.
