  3. Air Traffic Control Tower A proposed ATC tower uses a control console which has to be meet the needs of the particular airfield. Activities InvolvedDuration (weeks) Design console 3 Order console 2 Fabricate and deliver console 16 Install console 2 Test console 4 Design tower 5 Design foundations 1 Order foundations material 1 Deliver foundations material 1 Construct foundations 1 Order tower construction materials 2 Deliver tower construction materials 3 Erect tower 8 1. Draw the AoA network diagram (assuming that design of the foundations is dependent on the design of the tower). 2. Fill in all the information in the Table’s outline of the Early, Late, Floats and determine the Critical Path
