  • Land use near a major hazard facility

    When a proposal to build an aged care facility was received by a local council, a nearby major hazard facility lodged an objection to it. The council asked Broadleaf to investigate whether or not the objection was justified, and to be an expert witness in a formal public hearing. Our expertise in land use safety planning and regulatory requirements was useful in this process. In particular, we were able to guide the council to ask the right questions of the owner of the refinery to achieve a satisfactory planning outcome.

  • Cost uncertainty in a cable-laying contract

    This case study describes a quantitative risk analysis undertaken with a construction company that was preparing a bid to design and construct fibre optic broadband infrastructure in a regional area. The purpose of the analysis was to understand the uncertainty in the initial cost estimate for the activity, and to contribute to the company’s decisions about whether to bid and at what price. The case demonstrates the role of quantitative analysis of uncertainty as part of a contractor’s bid development process.

  • Strategic program to expand a portfolio of health products

    This case describes how an international pharmaceutical company used risk management to examine a significant long-term strategic agreement with another organisation in a complementary medical sector, for the purpose of developing improvement actions to enhance its success. The case discusses how the process was planned and conducted, and how the company’s enterprise risk management processes were tailored for the specific strategic and implementation decisions that were involved. It also discusses how the company made sense of the large amount of information generated in a series of risk-related workshops, to develop a practical and manageable set of improvement plans.

  • Optimising a public policy decision

    Public policy decision-making often involves choosing between policy options that are each subject to uncertainty. Individual uncertainties might be relatively well understood but it can be difficult to assess the combined effect of multiple uncertainties affecting both costs and benefits. This case study describes the use of Monte Carlo simulation to model the aggregate effect of multiple uncertainties associated with policy options for dealing with a potential animal health pandemic. The purpose was to assist policy makers to optimise their decisions in the context of tight political deadlines.

  • Breaking decision paralysis

    A client wished to increase the ventilation capacity of an underground mine to allow the working area to be expanded. A prefeasibility study had become bogged down with disagreements about major design criteria and trade-offs. Broadleaf was engaged to facilitate a quantitative risk assessment of the initial plans. The process exposed the important decisions that had to be settled before a firm plan could be developed. This helped to break the deadlock so the study could proceed.

  • COVID Safe music education and performance

    Throughout the world education has been disrupted by the COVID-19 pandemic. This is especially so with music education where, either singly or in ensembles, children and young adults learn how to master their instruments and play together in orchestras and bands. This is a particularly challenging environment for infection control, as it is difficult to require social distancing and mask wearing for groups of young people from different families and different schools. Particularly for wind instruments, where masks can’t be worn, the aerosol particles produced by an infected musician can carry viruses for a considerable distance. Grant Purdy has worked with Melbourne Youth Orchestras (MYO) for many years. This year he has helped them develop a strategy to continue to rehearse and explore music safely.

  • Pre-bid risks for a large construction contract

    This case shows how qualitative and quantitative assessments of uncertainty were used when preparing a response to a large, complex request for tender. The aim was to assist the bidders to understand the risks they would face and the implications for their businesses if their tender were accepted, and to develop a realistic view of the budget and contingency they would need. This helped them to develop a negotiating strategy, and to set an appropriate bid price.

  • Fire safety for a gas drainage plant

    This case describes an investigation into the fire safety requirements of a plant processing methane-rich waste gas from nearby mines. It demonstrates the value of tailoring the fire safety advice for the circumstances. In this case, instead of a detailed quantitative assessment of all possible fire scenarios, a comprehensive qualitative review of the fire scenarios and the general principles for their management was undertaken.

  • Replacing a high-voltage power line

    This case study examines a quantitative risk analysis of the capital costs of a high-voltage power enhancement project. It illustrates the value of integrating quantitative analysis into project workflows, and how the outcomes from the analysis can assist in allocating contingencies to cost items for project cost control. It also demonstrates that the assumptions about the shapes of the distributions used in quantitative analyses may not always be important in terms of their impacts on the outcomes from the analysis.
