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 April 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, irrigation, 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 equipment to the site significantly damaged the newly prepared and leveled ground for the lawn. The Arbor project manager arranged his first meeting with the ACME finance manager to complain that he would have to re-do the site for the lawn which would take an extra 3-5 days. The finance manager agreed that it was not Arbor's fault and that work would have to be re-done, but as there was no more funding available he

suggested that the project manager make the savings somewhere else from within the project. This was agreed but not documented.

By the end of January the landscaping site works were finished and the irrigation system was installed. Planting was to be done in three phases - shrubs, bushes and small trees first, then larger trees and finally the lawn. Shrub planting would take approximately 4 days, trees 7 days and the lawn would be laid in three separate operations over 2 days. On the first day after the planting commenced, some of the project team noticed a few small plants seemed to be missing or broken off. These were quickly replaced. Within the first 3 days after the last planting, however, it was noted that around 35% of the plantings had been destroyed by rabbits or hares (as it was later determined. Remember, this is in Australia.) The Project Manager was very concerned and called another meeting with the ACME finance manager. Although sympathetic, the finance manager agreed that tree guards needed to be placed around trees but that was a contingency that the Arbor Company should have considered. The Arbor project manager indicated that pests were ACME's problem and again the finance manager indicated that Arbor should make savings elsewhere within its contract.

The Arbor project manager reviewed his budget and costs and determined that the only way to re-coup the losses from having to replant the shrubs and protect them, was to plant fewer plants and smaller trees which came at a much lower cost. Another way to make some savings was to try and re-design the irrigation system using fewer sprinklers. Instant lawn was tentatively ordered for around the middle of March 2021 so that delivery would miss the hottest part of the year. Unfortunately, the commercial lawn growers had heavy demand at that time and advised that the last shipment could only be made by mid-February 2021. This was necessary to allow them time to plant new lawn ready for winter and spring clients. Arbor had no choice but to accept delivery in mid-February 2021. As it turned out, it was particularly hot when the lawn delivery was made over the 2 days, with hot gusty northerly winds.

By the third week of February 2021, the project was ahead of schedule by about three weeks due to the early delivery of the lawn, although the larger trees and plants had yet to be planted. Unfortunately, water coverage of the lawn proved to be barely enough in windy conditions and, with the sprinkler head reduction, did not fully water all areas. By this time Arbor was over-budget by about $24,000. Since the original project was scoped and started, the original finance manager had secured a new position with another company and was set to leave in the third week of February 2001, just as the lawn started to brown off and die in patches. The new finance manager, who started one week later, was asked by the company to continue in the role of her predecessor on the project.

1.2 As discussed in the case study, it is important that before a project is executed a clear project management plan is drafted. In the context of the ACME Fabricators project, discuss the significance of a project management plan. (20 marks)
