List of top Construction and Management Questions on Project management techniques e.g. PERT, CPM etc. asked in GATE AR

A construction project consists of 7 activities. These activities, their connecting events, and the three PERT times (optimistic, likely, and pessimistic), in days, are listed in the table below. The project starts on 27th July 2026. Assuming no holidays for the entire duration of the project except 15th August 2026, the expected date of completion of the project will be August 2026 (mention the date in integer).

Activity	Connecting Events	Three PERT Times (in Days)
P	1 to 2	4 - 6 - 8
Q	1 to 3	5 - 6 - 13
R	2 to 5	6 - 8 - 22
S	2 to 3	8 - 11 - 14
T	3 to 5	2 - 4 - 12
U	3 to 4	4 - 8 - 18
V	4 to 5	5 - 7 - 15

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).

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].\[\begin{array}{|c|c|c|c|c|} \hline Activity & Quantity (cu.m) & Manpower (persons) & Productivity (cu.m/man-day) & Immediate Successor Activity \\ \hline \text{A} & \text{96} & \text{8} & \text{3} & \text{C} \\ \hline \text{B} & \text{252} & \text{7} & \text{4} & \text{C \} & \text{D} \\ \hline \text{C} & \text{275} & \text{5} & \text{5} & \text{Nil} \\ \hline \text{D} & \text{126} & \text{6} & \text{3} & \text{Nil} \\ \hline \end{array}\]
