Resource challenges for housing reconstruction

Purpose – The purpose of this paper is to identify resourcing challenges that face housing rebuild following the 2009 Victorian “Black Saturday” bushfires in Australia and to examine the impacts of resource shortages on longer term community recovery.Design/methodology/approach – The research methodology included a longitudinal study which consists of a questionnaire survey, field‐based interviews and observations to track trends evident in the survey.Findings – A total of 28 months after the bushfires, reconstruction in the worst‐affected area, the Shire of Murrindindi, was proceeding slowly despite the institutions and procedures set up for recovery. This slow reconstruction was due to the unavailability of building resources. Changed Building Standards, increased building markets outside the bushfire zone, lack of economic incentives, combined with home owners’ socio‐economic vulnerabilities, created a chain of impacts on households’ ability to get resources.Research limitations/implications – The evid...

Organizational Networks and Recovery Following the Canterbury Earthquakes

Following a disaster, the recovery of organizations is influenced by the flow of resources and information through organizational networks. The 2010–2011 earthquakes in Canterbury, New Zealand, had major direct and indirect impacts on local organizations and the regional economy. This paper utilizes 47 organizational case studies to assess the role of organizations’ networks in their response and short-term recovery activities, and to explore the effects of networks on regional reconstruction and related sectors. The results are organized around four thematic analyses, focusing on organizations’ support network characteristics, the types of support mobilized to aid recovery, network adaptations for new post-quake demands, and the economic impacts of organizational networks in reconstruction. The paper discusses how organizations managed and utilized networks to reduce the impacts of the earthquakes and to adapt to altered post-quake environments. These empirical observations of post-quake organizational behavior can also inform regional economic impact and resilience modeling.

Development of Resilience Index in Transport Systems

This paper demonstrates the quantification of the resilience index (RI) in transport systems. The transport infrastructure can be managed by using the concepts of resilience. Vugrin, Warren, Ehlen, & Camphouse (2010) emphasized the enhancement of resilience in infrastructure before disasters and the establishment of efficient measures for the recovery of systems in an emergency. The concept of resilience has a significant influence on transport planning and operations for disaster preparation. Lee, Kim, & Lee (2013) investigated the concepts of resilience and examined case studies using valuable asset-management techniques in order to maintain the resilience concepts which should be introduced in transport infrastructure planning and operations. Therefore, this paper presents the RI based on Vurgrin et al. (2010) and Lee et al. (2010). The first part of this paper focuses on the measurement of the RI using the recovery-dependent resilience (Vugrin et al., 2010) in transport infrastructures. For quantifying the RI, we have developed various variables that are used to target an achievable or a desired system performance in disaster recovery efforts. The second part of this paper focuses on the applications of the RI in case studies. The examined cases are road networks in flooded areas, heavy snowfall districts, and landslide occurrence zones. Each case is analyzed for transport costs both under normal and disaster conditions using the transport demand estimation models. Finally, we quantify the RI, which is important for establishing the provision of safety, recovery, and rehabilitation of transport infrastructures in flooding, snowfall, and landslide areas.

Effects of a major disaster on skills shortages in the construction industry: Lessons learned from New Zealand

Purpose The purpose of this paper is to empirically investigate the effects of a major disaster on the management of human resources in the construction sector. It sets out to identify the construction skills challenges and the factors that affected skills availability following the 2010/2011 earthquakes in Christchurch. It is hoped that this study will provide insights for on-going reconstruction and future disaster response with respect to the problem of skills shortages. Design/methodology/approach A triangulation method was adopted. The quantitative method, namely, a questionnaire survey, was employed to provide a baseline description. Field observations and interviews were used as a follow-up to ascertain issues and potential shortages over time. Three focus groups in the form of research workshops were convened to gain further insight into the feedback and to investigate the validity and applicability of the research findings. Findings The earthquakes in Christchurch had compounded the pre-existing skills shortages in the country due to heightened demand from reconstruction. Skills shortages primarily existed in seismic assessment and design for land and structures, certain trades, project management and site supervision. The limited technical capability available nationally, shortage of temporary accommodation to house additional workers, time needed for trainees to become skilled workers, lack of information about reconstruction workloads and lack of operational capacity within construction organisations, were critical constraints to the resourcing of disaster recovery projects. Research limitations/implications The research findings contribute to the debate on skills issues in construction. The study provides evidence that contributes to an improved understanding of the industry’s skills vulnerability and emerging issues that would likely exist after a major disaster in a resource-limited country such as New Zealand. Practical implications From this research, decision makers and construction organisations can gain a clear direction for improving the construction capacity and capability for on-going reconstruction. Factors that affected the post-earthquake skills availability can be considered by decision makers and construction organisations in their workforce planning for future disaster events. The recommendations will assist them in addressing skills shortages for on-going reconstruction. Originality/value Although the study is country-specific, the findings show the nature and scale of skills challenges the construction industry is likely to face following a major disaster, and the potential issues that may compound skills shortages. It provides lessons for other disaster-prone countries where the resource pool is small and a large number of additional workers are needed to undertake reconstruction.

Housing the Workforce Following the Canterbury Earthquakes in New Zealand

Temporary housing following a large-scale disaster has a positive effect on household welfare and community recovery. Following the 2010 and 2011 Canterbury earthquakes, a shortage of temporary accommodation created barriers for the outside construction workforce to engage in repairs and rebuild in Christchurch. This study investigates the impacts of housing shortages for the overall recovery and the strategies adopted by both households and the workforce in the building industry. Findings suggest that the interplay among the industry strategies and household strategies for securing housing determines the magnitude and scope of economy-wide inflation. One unfortunate consequence of these industry strategies is that the pressures of resource shortages are likely to transit from the construction sector to quake-affected households. These findings have implications on the nature and design of pre and postdisaster planning programs in order to reduce the impacts of housing issues on household welfare and, at the same time, to the meet the needs of the construction sector if the scheduled rebuild works are to be achieved.
