You are given the site preparation and excavation works for the foundation of a large residential project close to downtown Miami. The land is 300 yards long and 200 yards wide. The site is reasonably level terrain with firm ground and less than 25% rock content. The project specifications require excavating 4 ft. of the entire land. You have identified a disposal site 3 miles away from the jobsite with a 6% slope upwards from the site to the disposal. The soil is majorly made up of common earth with 25% swell. You can make reasonable assumptions wherever information is not provided in the project description (e.g. about density and moisture content of soil, etc.). You need to clearly state your assumptions. You are required to define an equipment crew composition (e.g., mix of dozers, excavators, hauling trucks, loaders, and etc.) that you will use for this project. You need to search the web to identify appropriate equipment brands and models for your job. You are required to use the standard performance characteristics in the manufacturers' manuals or performance handbooks to determine all the metrics (e.g., bucket capacity, engine power, gross machine weight). Then you need to use these metrics to determine: a) Productivity of the crew/fleet b) Ownership cost and operation cost c) Tradeoffs of productivity versus cost (to compare different crew composition) d) Rent, lease, or buy decisions and rationales of making the decisions.
