Activities A and B are the first two activities of a project. Activity A takes 20 days to complete (5 day a week, 8 hour a day [5/40]) with a 6-member crew at an average hourly rate of $45. Activity B takes 14 days to complete, working 5/40 with a crew of 3 at an average hourly rate of $60. Both activities must be completed by day 30. Both activities are interruptible. Activity A has a critical Early Start at day 0, and non-critical Late Finish at day 30 Activity B is non-critical and it has a SS relationship with activity A, with 6 days of lag, and a LF at day 30. Material usage for activity A is 450 units per day, at $650/unit. (Waste included) Material usage for activity B is 1500 units per day, at $950/unit. (Waste included) Activity A uses 40% of a backhoe, at $1995/day. Activity B uses 60% of a pump truck, at $2500/day. a. Calculate the total cost of activities A and B combined.

Question #5: In the real world, a limited number of days can be taken out of the schedule before it becomes impractical to try to shorten the schedule further. Though it is impractical to take the exercise to the theoretical limit of shortening, there is a theoretical limit that prevents any further shortening of the project. What defines this theoretical limit, and what conditions exist in the schedule when this limit is reached? Explain each response in detail.
