NOTE: Read the case study carefully and answer the questions related to the case. Case Study: University of Johannesburg Solar Project Interruption of electricity supply by the main public power generating company in South Africa (ESKOM) has made the need to generate an alternative source of energy an imperative for many businesses whose operations are dependent on reliable electricity supply. The university of Johannesburg is a diverse, inclusive, transformational and collegial institution, with a student population of over 50 000, of which more than 3000 are international students from 80 countries. In 2018, the University of Johannesburg was saddled with the problem of persistent power failure which was impacting negatively on the smooth running of the high-level academic and administrative activities which characterise the daily operations of the university. Hence, the University of Johannesburg governing council saw the need to procure a solar facility for the densely populated DFC campus. The aim of the project was to design and construct a PV solar power energy generator for the Doomfontein Campus and grid terminals. This is to enable steady power supply for sustainable operations. The University of Johannesburg appointed anzi Solar Electric (NSE) as the principal consultant for the PV solar power project. The project charter was approved on February 4, 2019 and Ms. Thembi Magagula was appointment as the project manager. Mr Shaun Ndilamini (An alumini of U) the Managing director of Nzanzi Solar Electric (Ple) signed the contract The contract further includes a clause "a penalty fee of R100 000 will be charged for every month if the project is not completed on the due date". This is equivalent to the cost of procuring an alternative energy source, which the university was bearing at the time of approving this project. The major deliverables of the project include engineering designs, construction and installation of solar energy and interconnection systems. A budget of R2Million was approved for the completion of the project (Incil. Professional Fees and Contingencies). A formal site-briefing meeting was held on March 2, 2019 between Ms. Thembi Magagala (Nzanci Solar Electric) and the representatives of stakeholder groups from the different departments within the University of Johannesburg. The proposed PV solar is located at Doornfontein campus. It is located 800 meters west of Ellis park stadium and 1km south of Hillbrow police station. The project was approved to start on March 11, 2019 and end on 17 of May 2019 (50 days). This was to ensure steady supply of electricity during the fast approaching winter months and beyond. The project consist of the following phases pre-planning - feasibility study, site assessment, detailed construction design, solar construction, solar installation and handover phase.

Ms. Magagula again reviewed the data. (Note that optimistic time estimates can be used as crash times for all the project activities See table 2 above). She then gathered the project team. "People, if we are not 75% sure we'll finish the UJ Solar Project in less than 50 days. I want this project crashed! Give me the cost figures for target date of 45 days - also for 40 days. I need this project finish carly, not just in time 1 6 - NOTE: earliest start (ES), earliest finish (EF), latest start (LS), and latest finish (LF) 3/3
