Governing Risk Reduction in the Built Environment: the Case of Victoria, Australia


University of Melbourne, Australia

Human settlements represent significant and ongoing investments of human cultural, economic and physical capital. The development of cities and towns is informed by a number of dynamic forces that exert influence within the constraints of existing constructed environments. In particular, the relative “irreversibility” of the underlying patterns of infrastructure, roads and land tenure imposes considerable constraints upon risk management. In combination, this physical realm is managed to a greater or lesser degree by an array of government agencies responsible for spatial planning, infrastructure and transport, natural systems, and risk management.

Viewing governance as the wide range of actors and institutions with various formal and informal levels of influence, this paper’s goal is to critically examine the changes that have occurred over time in the management of natural hazard risks in the built environment of Victoria, Australia. The paper begins by reporting the results of a review of the main elements of the built environment in Victoria, and corresponding risk profiles according to the main hazard categories. A critical description of the agencies and processes associated with emergency management and risk reduction in Victoria is then reported.

The paper’s main finding is that that while significant and valuable changes have been made and continue to be made to the formal structures of risk management agencies over the last decade, a number of key factors have undermined the effectiveness of these measures. These factors include the path dependency of associated regulatory systems, such as urban planning, local government, transport and water catchment agencies, the difficulties of modifying existing settlement patterns, entrenched expectations of settlement types, the emergence of new categories of risk, and vulnerability and climate change. The paper concludes with key recommendations for change, particularly focusing on those relating to meaningful integration of urban planning with risk reduction activities.

Risk-informed Urban Planning: Adaptation of the Concepts of Siting and Design of Nuclear Power Plants towards more Resilient Urbanisation

Anton Georgiev ANDONOV

Currently half of the world’s population lives in cities. The concentration of people, assets and critical infrastructure in cities exacerbates the potential of natural and man-made hazards to cause catastrophic cascading effects far beyond city’s and national borders. In fact “Failure in Urban Planning” is classified as one of the 28 global risks in the Global Risk Report of the World Economic Forum and has been identified among those risks for which South-East Asia and Latin America are the least prepared.

The urban infrastructure largely determines the city’s resilience. The resilience is the capacity of a system to absorb the stresses imposed by natural and man-made hazards and it is a function of its robustness, redundancy and flexibility. Cities are complex and interdependent systems: a resilient city will be a system capable to use all elements of its infrastructure in order to respond effectively to an arbitrary hazard.

The contemporary urban planning often lack regulatory guidance regarding what is necessary to increase resilience. Urban planning is currently facing challenges that are subject of studies in other fields from decades. The nuclear industry for example utilises design approaches based on the concept of citing and designing of NPPs towards predefined acceptable risk level. In particular the concepts of defense in depth (DiD), classification of safety functions and definition of safety classes for structures, hazard identification, probabilistic risk analysis and more recently the risk-informed design have significant potential for modifications and adaptations for applications in urban planning.

Current paper provides a brief overview of the main concepts used in siting and design of nuclear power plants, outlines the similarities between a NPP and large city when considered as complex interdependent systems and summarise the basic elements of the proposed herein Risk-Informed Urban Planning as a tool to drive a more resilient urbanisation.

Risks of Industry 4.0 - An Information Technology Perspective


Fraunhofer IOSB, Germany

The term "Industry 4.0" denotes the advent of the fourth industrial revolution which will be characterized by the optimized and networked use of information across the complete life cycles of both products and production assets. The exploitation of Industry 4.0 paradigms in terms of economic benefit, flexibility and better-informed decision taking requires the availability and provision of adequate information across all engineering and production value chains in an interoperable way, preferably based upon international standards. Such information is the result of aggregation and fusion functions applied to (big) data from various heterogeneous sources, often under real-time conditions and from production plants under constant change and different ownership. This comprises a challenge for the provision of an efficient, secure and dependable information management infrastructure.

Up to now, an hierarchical structure of information technology (IT) systems, the so-called automation pyramid, is predominant in industrial production environments. This leads to a separation of office and production networks that shield the safety- and real-time critical field and controller level from inadequate access from upper levels and remote users. Now, with the application of the paradigms of the Internet of Things and Services (IoTS), there is an architectural trend towards a mash-up of networked smart devices and services, deployed within and across enterprises in order to enable new higher-level services and business models such as smart maintenance.

This contribution considers this architectural IT paradigm shift from a risk management perspective. What are the new risks and vulnerabilities associated with respect to security and dependability of production systems and critical infrastructures? How can these risks be taken into account already in the requirements analysis and design phase? What can be done in existing production environments for risk mitigation? The contribution provides a terminological structure and mirrors possible answers to these questions at emerging IoTS reference architectures.

Stress Tests for Critical Transport Infrastructure due to Natural Hazards: a Case Study in Bologna, Italy

Natural hazards, such as earthquakes, floods and landslides, have the potential to cause extensive damage to transport infrastructure. This damage can lead to significant losses due to the cost of repairs and the increase in travel times for passengers, which may have significant economic impacts. The EU-funded INFRARISK project has developed a stress testing methodology for critical transport infrastructure exposed to low probability, extreme natural hazard events. The aim of the project is to assist decision making with regard to the protection of critical transport infrastructure to ensure the resilience of such infrastructure against natural hazards. To demonstrate the methodology, stress tests are performed for a road network in Bologna, Italy, to evaluate the potential losses associated with low probability, extreme earthquake hazard scenarios. The selected road network is located along the Scandinavian-Mediterranean corridor of the trans-European transport network (TEN-T), which is considered a vital axis for the European economy and provides access to the city of Bologna. The vulnerability of the road network is evaluated according to the potential damage to the network due to seismic loading and earthquake-triggered landslides, and the risk is assessed in terms of the repair costs and the costs associated with the functionality loss of the network. The objective of the case study presented herein is to demonstrate the systematic application of a stress tests methodology for transport infrastructure to improve the resilience of urban environments to natural hazards.

Operationalization of an ISO 31000-Compliant Resilience Engineering Method, Applied to the Temperature Control in a Smart Building

In response to the increased complexity of socio-technical systems, risk management strategies become accordingly complex and their associated risk engineering approaches are stretched to their practical and methodological limits, as is the case of the Failure Mode and Effects Analysis (FMEA). In recent years resilience engineering has emerged as the discipline to close this complexity gap. This contribution links the principles of the novel Functional Resonance Analysis Method (FRAM) and FMEA, a well-established method, in order to propose a feasible approach to manage system complexity and achieving thus an ISO 31000-compliant approach to operationalize resilience engineering. For this purpose, the case study of temperature control in smart buildings was selected to mirror the increase of complexity of a socio-technical system. The combined FRAM-FMEA method was successfully applied and yielded results above the single application of the respective methods. The results of the case study show that during normal operation conditions temperature control on small buildings operates safely, being only vulnerable to extreme weather patterns and contradicting behavior among users. However, with the introduction of Internet of Things (IoT) the system becomes vulnerable to IT threats that can gravely endanger the system. On the methodological level, the results show that the combined method is suitable to semi-quantitatively assess resilience: it shows where the system can fail and what could it happen. While it inherits some of the limitations of the original methodologies, its application makes resilience analyses more efficient. It can be then concluded that FRAM can accurately describe small sociotechnical systems (<20 analyzed functions) but it may be challenging to apply for large projects (e.g. critical infrastructures). Nonetheless FRAM demonstrated to be a useful communication tool with experts and combined with FMEA, a practical semi-quantitative approach to resilience engineering.

Corrosion of RC structures in environmentally aggressive area of Persian Gulf, results in a considerable annual loss. It also has been shown that, the phenomenon increases the annual probable seismic loss and seismic risk of the important infrastructure in the region. Several management systems with a variety of tools such as destructive and nondestructive methods have been developed for observation of structural condition and enhance the performance of the facility during its life cycle. Therefore, application of innovative nondestructive methods for tracing the variation of structural and dynamic characteristics of such facility can enhance the different management systems. Among the methods different methods for health monitoring and identifying the dynamic characteristics of the structures are increasingly employed for similar purposes. In this study, peak-picking, Fourier spectrum, wavelet transformations and frequency domain decomposition(FDD), are studied investigate the capability of each method in identifying modal aspects, (e.g. natural periods, modal damping) of the structure. For this purpose, a numerical model of a bridge structure under chloride ion attack is developed in OpenSEEs software. Simulated response of the corroded structure ambient vibration is calculated under ambient vibration and the results of different mentioned methods are calculated. The results are also calculated using the numerical model and discussion are presented about the performance of each identification method. The results demonstrate the benefits and weak point for each method.
