Question 2 Maximum Word Count 1000 words Refer to Table 1. This table shims nom'ral durations and units, and crash durations and costs for the activities involved in one of the main project packages. Table 1 Activity normal and crash durations for the package Note: The crash dilation represents the minimum duration where an activity is speeded up as much as possible. The crash cost repremnts the increawd cost of the activity after it has been speeded up as much as possible. Note: Where the normal duration and crash dLlaOl'l are the same this activity cannot be crashed.

Calculate the most cost-effective way of completing the package within this time, giving the nal work package cost associated with this crash sequence. (10 marks) Assume liquidated and ascertained damages apply at a rate of 5,000 p_er week for completion later than the end of month 2?. Calculate the actual costs of crash and present it in a 'graphical report'. Explain what the duration is that gives the lowest total project cost. (10 marks) [Total 25 marks)
