[40 MARKS] Read the case study below and answer ALL the questions that follow. This project takes place in South Australia. In September 2020, ACME Fabricators advised its staff that their new factory and offices out in semi-rural Angle Vale would be ready for completion by the end of Apri 2022. ACME was a responsible company and liked to keep their premises clean and tidy and their staff happy. The new premises at Angle Vale were developed on a 4.5-hectare site, previously used for grain crops. Consequently, ACME decided that significant landscaping would be required to enhance the amenity of the otherwise bare land. The senior executive group pictured some land contouring with an attractive green lawn, and trees and shrubs to soften the impact of otherwise stark commercial buildings. Accordingly. they notionally allocated $232,000 for the project, and developed a tender document that called for the work to be completed by the time they moved to the new premises. They then invited proposals for landscaping and quotes for the work. A company called Arbor Industries submitted an artist's sketch for the ACME evaluation team to picture what the landscaping would look like. Arbor was selected with a bid of $175,000, substantially lower than any other submission. Arbor then prepared a detailed landscaping plan based on existing drawings of the site provided in the tender. Arbor met with the ACME senior executives to agree on a project start date, access and security of plant and equipment, and a fixed price contract. A contract was duly signed. The project was scoped and planned by Arbor, with specific milestones for site works, imigation, turf laying, and tree and shrub planting. Arbor had undertaken many similar jobs on city sites in the past and based on the knowledge and skills of the project team, they did not think that a formal project management plan would be needed. All they wanted was agreement on the scope of the project and the key deliverable dates. From experience, they wanted to deal with only one person from ACME and it was agreed that the finance manager, a senior executive, would be responsible for the project. Arbor commenced work on the 16th of November 2020 with site preparation including weed eradication. Work progressed smoothly until 20th of January 2021, when heavy vehicles delivering machinery, plant and Quipment to the site significantly damaged the newly prepared and leveled ground for the lawn. The Arbor oject manager arranged his first meeting with the ACME finance manager to complain that he would have re-do the site for the lawn which would take an extra 3-5 days. The finance manager agreed that it was Arbor's fault and that work would have to be re-done, but as there was no more funding available he
