The network diagram of a construction project is shown in the following Figure. The duration of each activity, in days, and the early start time of the project are denoted in the diagram. The total project duration along the critical path, in days, is _____(in integer).
Correct Answer: 18
Solution and Explanation
Top Questions on Project management techniques e.g. PERT, CPM etc.
- A construction project consists of four activities. The quantity of work, manpower requirement, and the productivity of the activities are listed in the table below. The interrelationship between the activities are also mentioned in the table. The construction project will start on January 29. Assume no holidays for the entire duration of the project. The project will finish on February \underline{\hspace{1cm}} [mention date in number].\[\begin{array}{|c|c|c|c|c|} \hline Activity & Quantity (cu.m) & Manpower (persons) & Productivity (cu.m/man-day) & Immediate Successor Activity \\ \hline \text{A} & \text{96} & \text{8} & \text{3} & \text{C} \\ \hline \text{B} & \text{252} & \text{7} & \text{4} & \text{C \} & \text{D} \\ \hline \text{C} & \text{275} & \text{5} & \text{5} & \text{Nil} \\ \hline \text{D} & \text{126} & \text{6} & \text{3} & \text{Nil} \\ \hline \end{array}\]

The time estimates obtained from four contractors (P, Q, R and S) for executing a particular job are as under:
\[\begin{array}{|c|c|c|c|} \hline \textbf{Contractor} & \textbf{Optimistic time, $t_o$} & \textbf{Most likely time, $t_m$} & \textbf{Pessimistic time, $t_p$} \\ \hline \text{P} & 5 & 10 & 13 \\ \hline \text{Q} & 6 & 9 & 12 \\ \hline \text{R} & 5 & 10 & 14 \\ \hline \text{S} & 4 & 10 & 13 \\ \hline \end{array}\]
