(a) Calculate the time duration of each activity and the variance.
(b) Draw the network diagram, determine the critical path and mark in the network. What is the total project duration?
(c) What is the probability of achieving the project within the deadline of 30 weeks?
3. How does resource leveling differ from resource allocation? Discuss various methods of resource leveling in project management.
4. Contract planning and contract negotiation stages are usually located in a control project office and contract administration is done at remote construction sites. What are the disadvantages of this distance gap?
5. What are the factors, which control the cost of a project? Discuss briefly on each. How does time over-run affect the project cost?
6. Write short notes on three of the following:
(i) Advantages of matrix organisation
(ii) PERT time estimate
(iii) Total float in the project network
(iv) Crashing of project
(v) Project management software packages
(vi) Quality control in project management

Overhead costs amount to Rs. 1,000 per week. It is stipulated that the contractor will have to pay a penalty of Rs. 2,000 per week for completing the project beyond 16 weeks
(i) Show the critical path in the network Diagram.
(ii) Find out the cost slope for every activity using normal and crash date for time and cost.
(iii) Crash the project to 16 weeks, Estimate the total cost of crashing.
