Involvement of construction management professionals in property-level flood adaptation

Flooding is a significant concern across the UK that has caused property damage, economic impact and health and safety concerns. The national climate change risk assessment for the UK projects the risk of flooding to increase in the future, and thus flood risk management is identified as an area that requires serious action. Whilst community level flood protection measures have been and are being put in places where there is an economic case for such intervention, the need for implementing property level flood adaptation (PLFA) is increasingly highlighted. This industry is worth £2.1 billion globally; with a forecasted UK growth at a rate of 7.1% by 2017-18. The aim of this research is to identify the ability of construction managers to provide PLFA advice to homeowners. Interviews were conducted with 10 professionals currently involved in flood adaptation product/service provision to gather their views on construction manager involvement within this niche area. Majority of participants interviewed accepted that construction managers could enter the PLFA industry. However, there has been a lack of evidence that suggest that construction managers have played a key role in this field. The paper suggests that there are several barriers that have resulted in the lack of involvement of construction managers in the PLFA industry. Previous research recognises lack of relevant skills and knowledge required to provide PLFA advice as a key barrier, this is supported by participants interviewed mentioning that the qualification, knowledge and training required were a barrier for construction managers to enter into the PLFA industry

Disaster risk reduction measures n Bangladesh

Disasters damage the entire economy of the country when they predominantly take place in developing countries. While no country in the world is entirely safe, lack of capacity to limit the impact of hazards has made developing countries being the most vulnerable nations to natural disasters. Bangladesh is being identified as a country that is vulnerable to climate change and subsequent natural disasters every year. Dense population and poverty has reduced the adaptability of Bangladesh in disastrous situations thus further increasing severity of impact from disasters. Owing to geographical settings, Bangladesh is currently ranked as one of the world’s most disaster-prone countries in the world. The frequent natural hazards such as cyclones, storm surges, floods, droughts, tornados,riverbank erosions, earthquakes, arsenic contamination of groundwater and landslides account for significant losses in human lives and physical assets while effects are further reflected in social settings, ecosystems and the economic well-being of the country. This paper evaluates the types of natural disasters Bangladesh is subjecting to, how they have affected the Bangladesh community and existing disaster risk reduction strategies. Paper also evaluates four main domains of disaster vulnerability reduction measures namely physical, engineering, structural and organisational. Existing disaster risk reduction strategies adopted in Bangladesh are linked with the aforementioned four domains of disaster vulnerability reduction measures. A comprehensive literature review is used as the research method. Literature synthesis suggests that Bangladesh is being using a combination of disaster risk reduction measures ranging from technical to social measures

Use of FBG sensors for SHM in aerospace structures

This paper details some significant findings on the use of the fiber Bragg grating (FBG) sensors for structural health monitoring (SHM) in aerospace fiber reinforced polymer (FRP) structures. A diminutive sensor provides a capability of imbedding inside FRP structures to monitor vital locations of damage. Some practical problems associated with the implementation of FBG based SHM systems in the aerospace FRP structures such as the difficulty of embedding FBG sensors during the manufacturing process and interrelation of distortion to FBG spectra due to internal damage, and other independent effects will be thoroughly studied. An innovative method to interpret FBG signals for identifying damage inside the structures will also be discussed

Proceedings of ARCOM Doctoral Workshop on 'Industry 4.0 and Disaster Resilience in the Built Environment': ARCOM Doctoral Workshop in association with CIB W120 - Disasters and the Built Environment

Disruptive innovations of the 4th industrial revolution are now starting to make an impact on construction. Although construction has lagged behind some of the other industries in embracing this revolution, recent years have seen a concentrated effort to drive change in construction processes and practices. The 4th industrial revolution is characterised by technologies such as digitisation, optimisation, and customisation of production, automation and adaptation; as well as processes such as human machine interaction; value-added services and businesses, and automatic data exchange and communication. In construction, the applications of Industry 4.0 include 3D printing of building components, autonomous construction vehicles, the use of drones for site and building surveying, advanced offsite manufacturing facilities etc. The application of technologies, processes associated with Industry 4.0 is seen to be already making an impact on construction, and reshaping the future of built environment. This new digital era of construction, fuelled by Industry 4.0, has significant potential to enhance disaster resilience practices in the built environment. Knowledge on resilience of the built environment including preparedness, response and recovery has advanced significantly over the recent years and we are now in an era where resilience is seen as a key constituent of the built environment. But the recurring and devastating impacts of disasters constantly challenge us to improve our practices and seek ways of achieving greater heights in our quest of achieving a resilient built environment. It is often proposed that the innovations associated with Industry 4.0 joined by IoTs and sensors can be exploited to enhance the ability of the built environment to prepare for and adapt to climate change and withstand and recover rapidly from the impacts of disasters. This integration of cyber physical systems through IoTs needs a holistic view of disaster resilience. Often, the focus is on benefits individual technologies can offer. However, the ability to integrate different aspects of disaster resilience using a range of new technologies promise to deliver wider benefits beyond and above what individual technologies can offer. For instance, an integrated digital twin allows to bring together advanced risk modelling, big data, cloud computing, internet of things, advanced off-site manufacturing, etc. together to deliver a resilient built environment. This requires careful planning and extensive research on the complexities surrounding disaster resilience related aspects and the use of related data. The ultimate objective of any new innovation, including Industry 4.0, should ideally be to benefit the society. The society that we live today is often disrupted by natural hazard induced disasters, whether it be floods, cyclones, earthquakes, landslides or tsunamis. The challenge that is in front of us is to effectively utilise new innovations driven by digital information to enhance disaster resilience in our buildings, communities, cities and regions. However, unlike earlier industrial revolutions, digital revolution is not easy to control. We must ensure that the fundamental values such as freedom, openness and pluralism are inbuilt in these new technologies. This is an uncharted territory for us. In addition to addressing complexities and challenges of using Industry 4.0 technologies, we also need to have policies and guidelines on the use of information. There should be a balance between innovation and regulation. We are confident that by bringing together researchers, practitioners and policy-makers alike from relevant disciplines we can deliver realistic benefits to transform our disaster resilience practices and policies, and make the built environment we live in more resilient

Disaster Risk and Community Vulnerability: the Case of Patuakhali, Bangladesh

Natural disasters have the potential to damage the entire economy of a country, especially when they take place in the developing countries. While no country in the world is entirely safe, the lack of capacity to limit the impact of hazards and bounce back after major natural disasters has made developing countries being some of the most vulnerable nations to natural disasters. Bangladesh is a South Asian developing country that faces variety of problems ranging from low income; a lack of assets such as land and permanent housing to ac-commodate the people; shortages of clean water and adequate food; inability to participate in commercial ac-tivity; high population density. Owing to geographical settings and environmental reasons, Bangladesh is currently ranked as one of the world’s most disaster-prone countries in the world. The frequent natural hazards such as cyclones, storm surges, floods, droughts, tornados, riverbank erosions, earthquakes, arsenic contami-nation of groundwater and landslides account for significant losses in human lives and physical assets while effects are further reflected in social settings, ecosystems and the economic well-being of the country. This paper evaluates the disaster risk and vulnerable factors in Bangladesh with particular reference to Patuakhali coastal region. Focus group discussions and semi-structured interviews were conducted with community, community leaders and local authority when collecting data for this study. Community identified Cyclones as the main disaster that creates devastating damages and losses to their lives, property and belongings. River erosion, Salinity and Floods were also identified as other disasters that affect socio-economic lives of the community. Geographical location, lack of sufficient cyclone centers, vulnerability of female, children and old people; and excessive love and devotion to property and animal were identified as factors that increase the vulnerability of community towards natural disasters
