The information given in Table 3.1 is from Project A and before cost objectives are integrated into the schedule. Table 3.1: Schedule for Project A before cost objectives are integrated. \begin{tabular}{|l|l|l|}\hline Activity & Predecessor & Duration in days \\\hline A & - & 3\\\hline B & A & 5\\\hline C & B & 6\\\hline D & B & 7\\\hline E & C, D & 5\\\hline \end{tabular} Question 3.2 : Now, the construction manager is in the process of integrating cost management objectives into the schedule. After a brainstorming session with the time and cost management teams, it is decided that Activity A cannot be crashed because of a technological restrain. Activities B-E can be crashed. The crash duration and the additional cost of crashing/day are calculated for Activities B-E (see the Table 3.2). Assuming a project overhead cost of \(\$ 700/\) day, identify the best target project duration considering both cost and time. Assume that the agreed project duration is 18 days and there is a penalty fee of \(\$ 100/\) day for delays after. Show all calculations clearly. Table 3.2: Schedule crashing possibilities for Project A.\begin{tabular}{|l|l|l|l|l|}\hline Activity & Normal duration (days) & Crash duration(days) & Normal cost (\$) & Additional cost of crashing per day (\$)\\\hline A & 3 & 3 & 2200 & -\\\hline B & 5 & 4 & 1800 & 800\\\hline C & 6 & 4 & 1900 & 400\\\hline D & 7 & 5 & 2000 & 800\\\hline E & 5 & 4 & 2100 & 600\\\hline \end{tabular}
