Question 1: Scheduling Techniques Problem Specification Consider the following network schedule: Table 1: Network Schedule of a Rugby stadium. Predecessor 1 Activity 1 2 3 4 5 6 7 8 9 10 11 Description Clear stadium site Demolish building Set up construction site Drive support piling Pour lower concrete bowl Pour main concourse Install playing field Construct upper steel bowl Install seats Build luxury boxes Install large-screen television Stadium infrastructure Construct steel canopy Light installation Build roof supports Construct roof Install roof tracks Install roof Inspection Approval Duration 70 days 30 days 70 days 120 days 120 day 120 days 90 days 120 day 140 day 90 days 30 days 120 days 75 days 30 days 90 days 180 days 90 days 90 days 20 days 10 days 2 1 1,4 2,5 2,5 2,5 6,8 6,8 6, 7(SS), 8 6,8 9 (SS) 13 5 15 15 16, 17 7,10,12,14,18 18,19 12 13 14 15 16 17 18 19 20 SS - Start to start lag Notes: A working day is Monday, Tuesday, Wednesday, Thursday and Friday (8 hours work). Staff works Mondays through Friday. Consider leap years Project start date is 1st April, 2022. The last Friday of every month is a sports day for the company. No work is done on this day. The following holidays are observed in a year. o January 1 - New Year's Day o Second Monday in January, April, and October - Eat-All-You-Can day o April 11 - Plagiarism Day o May 24 - National Dry Day June 18 - Love Your Neighbor Day o August 16 - National Rocky Road Day o December 20th - Blame Someone Else Day If a holiday falls on a Saturday then Friday will be given as an extra day off, and if it falls on a Sunday then Monday will be given as a day off. Two holidays cannot be on the same day. 0 2 Given the information provided in Table 1 and key notes, answer the following. Required: a) You are tasked to draw using appropriate software (i.e. not using any project management software) an AOA PERT chart for the above project; assuming a finish-start (FS) relationship between activities. (The length of the arrows must be indicative of the duration). (10 marks) b) How long will this project take? What is the minimum completion date? (2 marks) c) List all the distinct paths in the project along with their durations. (3 marks) d) Which tasks are on the critical path of the PERT chart above? (3 marks) e) Identify all Activities in the above project that have a slack and the amount of slack. (3 marks) f) The person working on activity 10 informs you he/she cannot start work until three days after the scheduled starting date. What impact would this have on the completion date of the project? (2 marks) g) If activity 17 is delayed by 30 days what will be the new project duration? If there is no effect, state 'No change in duration'. (3 marks) h) Convert the above AOA Chart to an AON Chart (also known as Project Network Diagram) clearly stating the ES, EF, LS, and LF for each of the activities. Use the node style given in lectures for your AON diagram. Consider the SS relation where stated. (10 marks) i) Create a Gantt chart for the above network schedule using appropriate software learnt in class, indicate appropriate milestones. (6 marks)
