Table 1 presents the activity data for a construction project. Based on the information in this table: (a) Construct a network precedence diagram (b) Determine earliest and latest times for all activities and calculate activity floats. (c) Clearly identify the critical path(s) on the network diagram. (d) Explain what will happen to the project if ? activity F is delayed by 4 weeks; ? activity G is delayed by 3 weeks.
