FACULTY OF CIVIL ENGINEERINGSKAA 4113 CONSTRUCTION AND PROJECT MANAGEMENT SEMESTER 1 – 2017 / 2018 ASSIGNMENT 3 Analyse resource requirement for manpower, machinery, material and money in construction project LECTURER : MR. ABDUL RAHIM B. ABDUL HAMID SESSION 2016/2017 Q15. . Which of the followings are the appropriate actions to control wastage on site? I. wastage on the site can be controlled. Resource levelling will generally: A.. I.to be obtained solely from the performing organization. Subcontract the works A.SEMESTER 1. II. Employ skill workers III. All of the above Reason: By employing skill workers and using precast materials. Q16.. An output of the process Estimate activity resources is a document called "activity resource requirements". It identifies the types and quantities of resources. Use precast materials IV. Q17. C.. Reason: Resource levelling is a technique in which start and finish dates are adjusted based on resource constraints with the goal of balancing demand for resources with the available supply.while the term resources is limited to equipment and materials. Double handling of materials II. . A.. Reduce the overutilization of resources. Reason: Activity resource requirements determines the resources for each work package and each work period... Reduce the time needed to do the project. Increase the total time necessary to do all the tasks. . On the other hand. II and III only C. . II and IV only B.required for each activity in a work package. Reduce resources to the lowest skill that is possible. double handling of materials and subcontract the works cause the wastage occurred on site. D.. III and IV only D.while the term resources is limited to human resources.. D. B. B. C... . Reason: Poor machineries and equipment output are caused by the problem of under capacity. Crashing works only for activities on critical path where additional resources will shorten the activity’s duration. Calculate Total Cost of this project: Assume six (6) working days a week except Sunday. Under capacity B.00. unskilled operators and lack of maintenance culture. C. Question 20 to 22 will refer to the following table: Table Q20-Q22 Activity Normal Time Crash Time Normal Cost Crash Cost (week) (week) (RM) (RM) 1-2 5 2 21000 27000 1-3 3 1 5000 8000 2-4 2 1 10000 12000 2-5 4 1 7500 12000 3-4 5 2 24000 36000 4-5 7 2 8000 22000 Q20. To bring the project on schedule. Resource planning C. Lack of maintenance culture.Q18. D. Timely replacement of parts.500 . The project is running late. Q19. You are the project manager responsible for building a new project. Fast-tracking B. Schedule Management Reason: Crashing is a technique used to shorten the schedule duration for the least increment cost by adding resources. Unskilled operators. you decide to add additional resources to the critical path. The problems related to the poor machineries and equipment output during construction are attributed to the followings. Given indirect cost per day is RM300. RM 75. Crashing D. except: A. A. This is an example of… A. 33 2-5 4 1 7500 12000 250 3-4 5 2 24000 36000 666.

Which activity indicates the highest increment if time compression needs to be done? A. 0. What is the cost performance index? A. The deviation from the original plan then have to be rectify.75 B. Instead.700 C. the person assigned to the task was 75% complete. and take two weeks to complete. The project manager is making sure that the product of the project has been completed according to the project management plan. Executing C. A decision has been made which activities 1-3 and 4-5 needed to be crashed 2 weeks each due to financial reason. the project manager was only able to assign one person to this task. Planning B.Q22. At the end of two weeks. After planning.50 . 1. Q24. RM 117. full time. What part of the project management process is he in? A. 0.15 Reason: In two weeks. BCWP = 100 75% = 75. ACWP = 50 CPI = BCWP/ACWP = 75/50 = 1. 1. RM 105. The implementation will have to be closely monitor to see how much it varies from the planning. Monitoring and controlling D.50 C.
