What is excess and borrow, and how are each considered in the estimate?
What will be an ideal response?
Excess is the soil that is to be removed from the site when all of the excavation is complete.
Borrow is the soil that must be brought to the site to complete the required excavation.
Once all of the excavation calculations are complete it can be determined if there is an excess or borrow situation. Excess soil must be hauled away. Borrow must be brought in. This affects the estimate in terms of selection of equipment, the amount of soil, and the length of haul. All of these factors impact the cost of excavation.

What will be an ideal response?
Elias wants to perform an after-tax evaluation of equivalent methods to electrostatically remove airborne particulate matter from clean rooms used to package liquid pharmaceutical products. Using the information shown, MACRS depreciation with n = 3 years, a 5-year study period, after-tax MARR = 7% per year, and Te = 34% and a spreadsheet, he obtained the results AWA = $ ? 2176 and AWB = $3545. Any tax effects when the equipment is salvaged were neglected. Method B is the better method. Now, use classical SL depreciation with n = 5 years to select the better method. Is the decision different from that reached using MACRS? After solving by hand, verify your answer using a spreadsheet
