CMGT 704 – Construction Estimating and Bidding
Lab – Excavations
Value: 25 Points
The objective of this assignment is to help you learn the methods for quantifying earthwork in construction estimating. For the attached site plan, calculate the volume of cut or fill needed to bring the entire site to an elevation of 90 ft. Assume any cut material can be used for fill.
Your assignment is to:
1. Find the net volume of cut or fill in BCY for the site using the Cross Section method.
2. Find the net volume of cut or fill in BCY for the site using the Grid method.
3. Find the net volume of cut or fill in BCY for the site using the Quick-and-Dirty method.
4. Compare the results of the three methods and indicate which method you think is optimal for this site (you must explain you logic in order to receive credit)
5. Find the number of haul loads needed to either bring in fill or remove excess soil from the site if one truck has a capacity of 12 cubic yards.
