1 Figure 1 below shows an activity diagram for a construction project. The time needed for each activity is given in days.
- Find the earliest start time and latest finish time for each activity and insert their values on Figure 1.
- Find the critical paths and state the minimum time for completion of the project.
- On Figure 2 opposite, draw a cascade diagram (Gantt chart) for the project, assuming that each activity starts as early as possible.
- A delay in supplies means that Activity \(I\) takes 9 days instead of 2 .
- Determine the effect on the earliest possible starting times for activities \(K\) and \(L\).
- State the number of days by which the completion of the project is now delayed.
