Eco-Machines Limited (EML) is a specialist power company and has recently initiated a challenging project to replace an existing diesel generator at customer premises, with a new water turbine to provide cheaper electricity for the customers manufacturing processes. Currently, a project-planning group has been formed, with representatives from both companies, and a series of key activities have been identified, together with a logical network diagram for the project. Project task information and the initial logical network diagram has been outlined in Figure 1 below.

1-Using the initial logical network structure within Figure 1 as a basis, complete the diagram using critical path method to calculate the minimum project duration. What is the project duration? (Write your question 1 answer in the first answer box.)

2-The group has identified that the resource EML has been ovellocated. Apply the resource levelling method to solve resource overalocation problem. what is the duration now? (Write your question 2 answer in the second answer box)

3-Which activity(s) has free slack after resource levelling? (Write your question 3 answer in the third answer box).
