6. A contractor is planning to use a backhoe to excavate for the foundation of a bank building she is constructing. The 10-foot deep foundation will be 60 feet long by 40 feet wide. To meet her construction schedule, the contractor needs to excavate the foundation in two days. She has determined the percent swell for the sandy clay soil to be 16%. What size backhoe (bucket size) should she select for this job, if job conditions are considered average and the machine operates 50 minutes per hour and eight hours per day?

For an earth-moving project, the contractor is required to locate a source of off-site borrow soil to use for compacted fill. Two possible sources are found; the cost of purchase and hauling from either will be comparable. At location A, the soil is a silt–clay material and is found to have a natural moisture content in the 10- to 20-percent range. At location B, the soil is also cohesive and is found to have a natural water content in the 30- to 40-percent range. The contractor selects location A. Indicate whether this represents a good choice, and why.

Please explain and solve the question
A twenty-story hospital building with a 400 ft x 200 ft footprint is to be built on a site underlain by fill over glacial sands. The building will have a 25-ft deep basement and will probably be supported on either a mat foundation located 5 ft below the bottom of the basement, or a deep foundation extending about 100 ft below the bottom of the basement. The groundwater table is about 30 ft below the ground surface and bedrock is about 120 ft below the ground surface. There are no accessibility problems at this site. (a) How many exploratory borings will be required as per NYC Code, and to what depths should they be drilled? (b) How would you obtain groundwater data? Explain your answer.
After the soil samples are taken and the soil properties determined, the engineer must design the foundation. It typically takes the engineer 4.75 days to design a foundation with a standard deviation of 0.83 days. Use this information and the information provided in Problem I to answer the following questions: a. What is the probability of completing all of the work (field sampling, testing, and design) within 43.5 days? b. The engineer completes the field sampling and testing in 36 days. What duration of the design work should be planned in order to ensure with 85% confidence that all of all of the work will be completed within 43.5 days?
