Table 1 presents the activity data for a construction project. Based on the information in this table: (a) Construct a network precedence diagram. (5 marks) (b) Determine earliest and latest times for all activities and calculate activity floats. (6 marks) (c) Clearly identify the critical path(s) on the network diagram. (2 marks) (d) Explain what will happen to the project if activity F is delayed by 4 weeks; activity G is delayed by 3 weeks. (4 marks) (e) Draw bar charts from the network based on early start schedule (i.e. assume all activities start as early as possible) and late start schedule (i.e. assume all activities start as late as possible).
