Question Consider the project data given in Table 1 and answer the following questions: 1.1 Draw an activity on arc diagram of the project schedule. (3) 1.2 Identify the critical path and its duration (2) 1.3 What is the normal total cost of the project? (2) 1.4 If the total fixed cost per day is R10000 of which R5500 is discretionary, set out the programme to be followed to achieve the minimum project costs and determine the reduced total project time at this minimum cost. (15) 1.5 What is the minimum project cost after acceleration?
