Question 1 Activities and their interdependencies for a construction project are given in Table 1.1. Use the information given to: (a) Construct a network precedence diagram for these activities (10 marks) (b) Determine earliest and latest times for all activities and calculate activity floats (12 marks) (c) Clearly identify the critical path on the network diagram (2 marks) (d) Explain what will happen to the process: (1) if activity H is delayed by 4 weeks; and (2) if activity F is delayed by 5 weeks. (6 marks) (e) Draw a bar chart 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. (10 marks) Table 1.1: Activity data for a construction contract
