problem 1)
(a) Project Corniche concerns the construction of a high profile modern house. From the scope statement, you can gather the following key words: Ground floor+ 1, pool, garage, back garden, bedrooms upstairs, attached bathroom. Draw a Work Breakdown Structure for this project up to WBS Level 3.
(b) What are the 5 Process Groups? In which Process Group are Feasibility Studies usually carried out?
(c) During a status meeting for a major building construction project, the client increases the scope by adding new features to the exterior architecture to blend with the surrounding natural environment as required by the newly promulgated Building Guidelines for this region. Using the concept of Triple Constraints, describe the impact that this change will have on the project.
problem 2)(a) Consider the following table of activities
(i) Draw the Network Diagram for these activities.
(ii) Find the Latest Start and Latest Finish times for the activities. Hence find the float for each activity.
(iii) What is the Critical Path?
(iv) What will happen if Activity A is delayed by two days?
(b) Your organization wishes to renovate its construction equipment by replacing used parts. An experienced mechanic was hired to do the repair and parts replacement jobs. The mechanic has submitted the following information:
• If the parts are relatively simple and the easy to replace, the exercise will take 50 hours.
• If something goes wrong that would require additional works, he expects the exercise to take probably 60 hours.
• If he runs into unforeseen problems, with unavailable parts whereby replacement parts will have to be manufactured at the metal workshop, it will take closer to 130 hours.
• if the mechanic charges Rs 100 per hour, what is the expected cost?
problem 3)(a) Aruba Company intends to develop a new product: either a Baby Shampoo or a Sun Lotion. The market for each product is known if the products can be successfully developed. However, there is some chance that it will not be possible to successfully develop them. Revenue of MUR 1,000,000 would be realized from selling the Baby Shampoo and revenue of MUR 400,000 would be realized from selling the Sun Lotion. Both of these amounts are net of production cost but do not include development cost. If development is unsuccessful for a product, then there will be no sales, and the development cost will be totally lost. Development cost would be MUR 100,000 for the Baby Shampoo and MUR 10,000 for the Sun Lotion.
(i) Using a decision tree, show the different alternatives and outcomes.
(ii) If the probability of having successful development of the Baby Shampoo is 0.5 and that of the Sun Lotion is 0.8, using Expected Monetary Value, determine the best alternative.
(b) describe what are the possible strategies which can be adopted when planning risk responses for a Positive Risk?
