ANSWER ANY THREE (3) FROM THE FOLLOWING QUESTIONS.QUESTION 2Elemental cost analysis (EGA) has been identified as an effective cost control tool in projectdevelopment and as such they may be used in preparation of preliminary estimate todetermine the cost limit of a project.a) Explain the criteria in selecting the most suitable EGA to be used as the basis of anestimate. (5 marks)b) Briefly describe the possible adjustments that may be done to the EGA to ensurethat the estimate is reliable by giving a sample project. Use the following format (ofEGA) as your guidelines in identifying the possible adjustments,

i. Form 1 - Information on project and analysis of single buildingii. Form 2- Simplified brief cost analysisiii. Form 3- Brief specification (20 marks)QUESTION 3a) Discuss the approach that the Quantity Surveyor should take to control cost duringpost contract stage. (15 marks)

b) Explain how cost of variation works could be controlled in a government project.(10 marks)QUESTION 4a) "Tender-based index is generally accepted by the estimator to be more suitable inachieving reliable cost estimates than other types of indices".

Discuss this statement and give your reasons why this statement might not alwaysbe true. (15 marks)b) List down the reasons why some estimators are reluctant to use indices in doingadjustment fo r their estimates.
