The Greater Bay Area initiative of the Chinese government to develop the area covered by Hong Kong, Macao and the nine cities in Guangdong Province is bringing many unprecedented opportunities for the region. Constructing the massive new urban infrastructure to support the initiative and ensuring that the development is sustainable are among the most important ones.

The Faculty of Construction and Environment (FCE) has a wide range of expertise in the fields of construction and environment. Consisting of the Department of Building and Real Estate, the Department of Building Services Engineering, the Department of Civil and Environmental Engineering, and the Department of Land Surveying and Geo-Informatics, FCE is at the forefront of leading and engaging in multi-disciplinary and cutting edge research on sustainable urban development.

Against this backdrop, the Translational Research Forum on Sustainable Urban Development in the Greater Bay Area aims to provide a timely platform for researchers, business leaders, industry practitioners and government officials from the Greater Bay Area and beyond to (i) identify and discuss challenging issues in the Greater Bay Area development; (ii) showcase the latest research in sustainable urban development, especially in construction, energy, environment, urban informatics, and urban hazard mitigation research; (iii) discuss how translational research can benefit the Greater Bay Area development; and (iv) explore cross-sector win-win collaborations.

In addition to 13 keynote speeches from leading scholars and practitioners on different aspects of sustainable urban development, the forum consists of 3 parallel sessions with the relevant themes of environment, atmosphere, and energy; smart city and mobility; as well as smart construction.

The success of the forum was due to the concerted efforts of many people.

Creating a GREAT Smart City with Digital Twin and IoT Technologies

Dr Jack ChengAssociate Professor Department of Civil and Environmental Engineering The Hong Kong Unversity of Science and Technology

AbstractThe development of smart cities is an emerging and important research direction, both locally and internationally. For example, the HKSAR Policy Addresses have stated several times the development of Hong Kong into a smart, livable city by means of innovation and technology. A smart city should not only focus on application of smart technologies like artificial intelligence and sensors, but also be green, resilient, empowering, adaptable, and transformative (GREAT). To be a GREAT smart city, a digital twin platform to bridge the physical world and the digital world is necessary. Moreover, the Internet of Things (IoT) provides rich sources of data to support a connected, dynamic, and intelligent built environment. This talk will introduce the GREAT attributes of a smart city and show examples of innovation and technology as an enabler. In particular, the application of digital twin and IoT technologies for a GREAT smart city will be demonstrated. Challenges will be discussed at the end.

Flood Modelling and Hazard Risk for Extreme Events in Urban Environments

Prof. Roger FalconerFellow of the Royal Academy of EngineeringEmeritus Professor School of EngineeringCardiff UniversityUK

AbstractIn recent years there has been an increasing global awareness of the impact of climate change on flooding intensity, particularly with regard to increased rainfall intensity, higher peak river flows and increasing sea level rise. Flood events, particularly in steep river basins, can cause loss of life in extreme circumstances, significant damage to property, and increased hazard risks due to vehicles floating and people losing their stability in floodwaters. One such event occurred in the village of Boscastle in 2004, where over 100 vehicles floated and moved due to an extreme flood event, with vehicles blocking the main village bridge and significantly increasing the upstream extent and impact of the flood.

In this presentation, some details will be given of the key challenges associated with modelling and managing floods, particularly for steep river basins and urban environments, and focusing on: (i) the key challenges of accurately modelling peak flood elevations and inundation extent, particularly for extreme events; (ii) the opportunities for planning the design of urban cities etc. using novel approaches to model buildings; (iii) the use of, and the need for, a sound understanding of the appropriateness of various property flood protection products and resilient flood solutions for different river and urban environments; and (iv) the development and application of new formulae for the movement of vehicles and the stability of adults and children in flood events.

About the SpeakerRoger Falconer is Emeritus Professor of Water and Environmental Engineering, following his role as Professor (1997-2018) and Founding Director (1997-14) of the Hydro-environmental Research Centre in the School of Engineering at Cardiff University. He continues his research interests in hydro-environmental modelling and his models have been used in over 100 Environmental Impact Assessment studies worldwide and provide the engine for the commercial 2-D model Flood Modeller Pro.

Visioning Sustainability in Megaprojects: Engaging with Multiple Narratives

Prof. Stuart GreenProfessor School of Construction Management and Engineering University of ReadingUK

AbstractIn the context of global concerns about climate change, the broader concept of sustainability continues to defy universal definition. The notion of the triple bottom-line is well-accepted, but the basis upon which trade-offs are made between environment, economic and social dimensions remains contested. The challenges are especially pronounced in the context of global mega-projects. In such arenas the concept of sustainability is invariably subject to multiple interpretations by a diverse range of stakeholders. The successful ‘visioning’ of sustainability is hence dependent upon the formation and maintenance of a stable narrative. Drawing from the ‘narrative turn’ in organization studies, it is contended that the projection of such a narrative is a key success factor for those responsible for sustainability in mega-projects. Such narratives need to engage a broad diversity of perspectives while at the same time providing a shared sense of purpose across multiple constituencies. When advocating the cause of sustainability, senior managers routinely oscillate between performative narratives of sustainability and more personalized stories derived from their own experience. Such a perspective provides fresh theoretical insights into sustainability on mega-projects, while at the same time providing practical guidance to practitioners.

About the SpeakerStuart Green is professor of construction management at the University of Reading, UK. He has over 30 years’ experience in construction research and related policy domains. He has an international reputation for his analysis of the construction improvement agenda with a particular emphasis on the contested meanings of commonly accepted terms such as sustainability. From 2007 to 2013 he served as a core commissioner on the Commission for a Sustainable London 2012 which provided strategic assurance on the sustainability of the London Olympics. Stuart enjoys extensive policy connectivity and is frequently invited to contribute to international debates. From 2011 to 2016 he chaired the Chartered Institute of Building’s (CIOB) Innovation and Research (I&R) Panel. He has been a frequent visitor to Hong Kong for more than twenty five years and was a member of the built environment panel in the 2014 Hong Kong Research Assessment Exercise (RAE). He is a guest professor at Chongqing University where he is honorary international co-director of the Joint International Research Laboratory of Green Buildings and Built Environments, funded by the Ministry of Education, P.R. China.

The Industrial, Social and Environmental Benefits Generated from Research on Offshore Foundations Achieved through Engaging with Industry

Prof. Richard JardineFellow of the Royal Academy of EngineeringProfessor of Geomechanics and Deputy Head of Civil and Environmental Engineering Faculty of Engineering Imperial College LondonUK

AbstractGeotechnical Engineering is now sufficiently mature to offer significant benefits to some of the more pressing problems faced by mankind. Richard Jardine explains how research into offshore foundations has been vitally effective in maintaining reliable supplies of oil and gas over recent decades. He goes on to show that recent research now offers opportunities for reducing the negative effects of CO2 dioxide emissions on the world’s climate by making offshore renewable wind-energy increasingly attractive from economic as well as environmental perspectives. The UK currently has the world’s largest installed offshore energy capacity, at around 38% of the total, and the recent advances in foundation research described in the talk have helped to halve UK wind-energy costs since 2015, achieving costs around 50% lower than new nuclear power stations. Many new offshore wind projects are starting in Northern Europe, where most installations have taken place to date, which will reduce both energy prices and CO2 emissions. These benefits are now spreading more widely to the USA and the Asia-Pacific rim, with many new projects in the pipeline. Geotechnical engineers working in China, Hong Kong, Japan, Taiwan and other ASEAN countries will need to engage with the new developments described in the talk.

About the SpeakerProf. Richard Jardine is Professor of Geomechanics and Deputy Head of Civil and Environmental Engineering at Imperial College London, where he undertakes research, administration and both undergraduate and postgraduate teaching. He is also serving (2018 - 2021) a second term as College Consul for Engineering and the Business School, having led the Geotechnics group (2005-2011) and undertaken Panel membership for the UK’s national Research Assessment Exercises in 2008 and 2014. He was elected fellow of the UK’s Institution of Civil Engineers in 2001, the Royal Academy of Engineering in 2002, the City and Guilds Institute in 2008 and the Japanese Society for Promotion of Science (2018). He is an honorary member of the Japanese Geotechnical Society.

Prof. Jardine’s research areas include soil properties, advanced laboratory and field measurement techniques, soil characterisation, offshore geotechnics, foundation analysis, slope stability, driven pile behaviour, soft ground engineering, geotechnical instrumentation and cold region geotechnics.

Opportunities for Hong Kong Construction Industry in the Greater Bay Area

Ir Sai-Hung Lam, JPPermanent Secretary for Development (Works)Development BureauHKSAR Government

AbstractThe development of Guangdong-Hong Kong-Macao Greater Bay Area (GBA) forms the key strategic planning in China’s development blueprint. Through collaboration and integration among the nine contiguous cities in Guangdong Province and the two SARs, the potential of these cities will be unleashed and the GBA will become a world-class bay area, fostering huge investment demand and strong economic growth. Following the commissioning of the Guangzhou-Shenzhen-Hong Kong high speed rail, the Hong Kong-Zhuhai-Macao Bridge and the upcoming Liantang/Heung Yuen Wai Boundary Control Point, the Hong Kong construction industry could seize the opportunities by offering seamless professional services to other GBA cities with the enhanced transport connectivity.

The recent reforms in the Hong Kong construction industry advocating innovation, technology and sustainable development definitely help deepen the cooperation with the Mainland. With the unique advantages of “one country, two systems” and the well-experienced multidisciplinary workforce with international exposure, the Hong Kong construction sector could showcase our high standards of professional practice through more collaboration with other GBA cities. The Free Trade Zones in Qianhai, Hengqin and Nansha provide a timely platform for the adoption of Hong Kong mode of project management in pilot projects. The Hong Kong professionals, especially the young generation, should grasp these opportunities for building their career through participation in this visionary plan.

About the SpeakerAfter obtaining his BSc (Eng) from the University of Hong Kong (HKU) in 1983, Ir Lam joined the Government of Hong Kong. Since then, he has been involved in planning and implementing various public works projects including bridges, roads, site formation and railways. He was the Director of the Civil Engineering and Development Department of the HKSAR Government from 2016 to 2018, overseeing the implementation of various new development areas and major infrastructures. In October 2018, he was appointed Permanent Secretary for Development (Works) overseeing public works policy and infrastructural development. Apart from practising as a professional engineer, Ir Lam is also an adjunct professor of the HKU.

Translation as a Fundamental Component of Research

Prof. David Nethercot OBEFellow of the Royal Academy of EngineeringEmeritus Professor of Civil EngineeringDepartment of Civil and Environmental EngineeringFaculty of EngineeringImperial College LondonUK

AbstractIt is often claimed that the essential difference between research in science and research in engineering is that, whilst the former may be justified solely on the basis of curiosity, the latter has a purpose. Put another way, science is about discovery whilst engineering is about benefits. How does this concept apply to civil engineering with its focus on projects rather than products, especially when the outcome of much civil engineering research is improved knowhow rather than better things?

Using examples from the distant and recent past, as well as reflections on the present and likely future, the author will attempt to show that the best civil engineering research has always had the concept of producing an identifiable benefit - either immediately or over the longer term - as an integral part of its content. Conversely, many of the papers one sees published nowadays appear to be exercises in ‘what can I do next?’ Interestingly, organisations seeking to evaluate the quality of engineering research are turning to impact as one of the measures of excellence. Put more starkly, how does your piece of research fare in the ‘So what’ test?

About the SpeakerDavid Nethercot was for the 12 years up to his retirement in 2011 Head of the Department of Civil and Environmental Engineering at Imperial College London. He holds PhD and DSc degrees from the University of Cardiff, is a member of the National Academies of Engineering of the UK, Australia and the USA, is a recipient of the Institution of Structural Engineers Gold Medal and was awarded an OBE for services to Structural Engineering. He is a past president of both IStructE and IABSE. His research on steel structures has influenced Structural Codes in the UK and beyond; his 40 years of experience of writing such documents currently includes chairing the British Standards committee responsible for all Structural Codes. His advisory work includes Wembley Stadium roof, the Queensferry Crossing and the Gerrards Cross tunnel collapse. David has had associations with Hong Kong dating back to 1986, has made some 70 visits and is presently serving as a Distinguished Chair Professor at PolyU.

Practice and Prospects of the Hong Kong-Zhuhai-Macao Bridge Construction Project

Mr Quanke SuChief EngineerThe Hong Kong-Zhuhai-Macao Bridge Authority

AbstractThe Hong Kong-Zhuhai-Macao Bridge is a super-large-scale cross-sea traffic project under the framework of “One Country, Two Systems” and the first collaboration between Guangdong, Hong Kong and Macao. It was named one of the 7 Wonders of the New Century by the British Guardian. As a test field for the construction of the Guangdong, Hong Kong and Macao Greater Bay Area (GBA), the “hard infrastructure” of the Hong Kong-Zhuhai-Macao Bridge will play an important role in the mechanism for its “soft infrastructure”. This report will share the successful experience of the construction of the Hong Kong-Zhuhai-Macao Bridge as a point of reference for the construction of the GBA as well as explore collaboration in science and technology innovation among Guangdong, Hong Kong and Macao following the opening of the Hong Kong-Zhuhai-Macao Bridge.

About the SpeakerSu Quanke is a member of the 13th National Committee of the Chinese People’s Political Consultative Committee, a senior engineer at the rank of professor, supervisor of PhD candidates, and chief engineer of the Hong Kong-Zhuhai-Macao Bridge Authority.

Since the early 1990s, he has been involved in trans-oceanic projects, with the construction of China’s first modern suspension bridge (Shantou Bay Bridge). Beginning in 2004, he has served as the chief engineer of the Hong Kong-Zhuhai-Macao Bridge project, and has led the technological and research works throughout the construction of the Hong Kong-Zhuhai-Macao Bridge. His innovations in the quantitative design theories and methods for the durability of concrete structures, the key technologies for disaster prevention and mitigation of super long sea-crossing bridges and submerged tunnels, as well as the complete sets of technologies and standards for industrialized bridge construction have been widely used in the industry.

Role of Fiber-Reinforced Polymer (FRP) Composites in the Development of Sustainable Coastal and Marine Infrastructure

Prof. Jin-Guang TengAcademician of the Chinese Academy of SciencesKo Jan Ming Professor in Sustainable Structures and Materials President Designate of The Hong Kong Polytechnic University

AbstractThe socio-economic development of coastal cities like Hong Kong relies heavily on their coastal and marine infrastructure (e.g., ports, bridges, artificial islands and offshore wind farms). A major challenge for coastal and marine infrastructure is steel corrosion, which is the main cause for infrastructure deterioration. To overcome this deterioration problem, extensive recent research has explored the use of fiber-reinforced polymer (FRP) composites in structures in marine and other corrosive environments. This presentation will start with a brief overview of research in this area, followed by a more detailed presentation of recent research conducted by the speaker’s group on hybrid FRP-concrete-steel structures incorporating a filament-wound FRP tube. In these hybrid structures, the three materials are combined in an optimal manner to deliver excellent performance in both load resistance and durability, with the FRP tube fulfilling the three important functions of formwork, protective skin and confinement to the concrete.

Synergetic Development: Performance-based Planning for Sustainable Aging Community in the Greater Bay Area

Prof. Jin Yeu TsouProfessorSchool of ArchitectureThe Chinese University of Hong Kong

AbstractEstablishing a livable built environment for urban inhabitants is a predominant basis to support the visionary plan of the Guangzhou-Hong Kong-Macao Greater Bay Area, which has been positioned as a new engine to empower economic and innovation growth. According to the status quo, an aging population and the continued urbanization are two concurrent demographic shifts faced by the cities in the Greater Bay Area. How to adapt the existing urban fabric to aging communities is critical to the success of realizing sustainable urbanism in this region.

Joint efforts are needed to drive the implementation of performance-based urban planning and design approaches in the high-density urban context, including not only integrating technical applications and theoretical studies but also understanding how social differences affect urban residents’ everyday life and perceptions of the built environment. Synergetic development through pooling resources and the respective advantages of cities in the Greater Bay Area is highly suggested. In addition, it is strongly appealing to foster an environment and mechanism in the Greater Bay Area that is attractive to young talents and suitable for talent growth.

Recent Developments on Urban Public Safety and Disaster Prevention at the University of Macau

Prof. Ka-Veng YuenRegistrarThe University of Macau

AbstractThe University of Macau has established its third State Key Laboratory very recently on the Internet of Things for Smart City. This laboratory includes two core technology areas: smart data transmission and networking, and big data and intelligent technology; and three application areas: smart energy, smart transportation, and urban public safety and disaster prevention. In this talk, we will introduce the laboratory development with major focus on urban public safety and disaster prevention. In particular, our major development has been concentrated on the structural health monitoring for infrastructures and electro-mechanical systems. Two recent techniques will be introduced. The first issue is on the optimal placement of multiple-type sensors. The information entropy is proposed as the measure of the efficiency of different sensor configurations. Furthermore, by taking advantage of Bayesian analysis, an efficient forward sequential sensor placement strategy is proposed. Another critical issue of structural health monitoring is the large number of unknown parameters in important civil engineering infrastructures. This induces critical computational difficulties of the problem. We will present a new substructure identification method which can isolate some critical portions of the structure for identification. It resolves the unidentifiable problem in existing substructure identification approaches.

About the SpeakerProf. Yuen is the registrar and Distinguished Professor of the University of Macau (UM). In 2002, he received his PhD from the California Institute of Technology after 2 years and 7 months of study.

Abstract“The Great Bay Area” refers to the Chinese government’s scheme to link Hong Kong, Macau, and nearby nine cities in Guangdong Province into an integrated economic and business hub. The development of the Greater Bay Area has a significance impact on the innovation-driven development in the region and its commitment to reform and opening-up. Regional planning can help ensure efficient placement of land-use activities, infrastructure, and settlement growth across a larger area of land rather than just an individual city or town. Such planning helps reduce conflicts and competition for resources among cities. The rapid population growth in the Great Bay Area has led to challenges including stifling traffic, difficulties in dealing with natural disasters and tests to the administration in expanding municipal governments. This presentation will focus on the unique issues in regional planning for the Great Bay Area and also address the strategic shifting of future urbanization models and smart city solutions being pioneered in China to combat problems in developing the city clusters.

Construction Safety in the Greater Bay Area - a Case Study of the Hong Kong-Zhuhai-Macao (HKZM) Bridge

Prof. Albert ChanHeadDepartment of Building and Real EstateThe Hong Kong Polytechnic University

AbstractThe blueprint for the development of Guangdong-Hong Kong-Macao Greater Bay Area (GBA) has attracted a lot of attention for its ambition to transform the two Special Administrative Regions of Hong Kong and Macao and the nine municipalities in Guangdong Province into a new Silicon Valley-type technology and innovation hub. In line with this huge initiative, a number of megaprojects have been constructed/ will be built to provide the necessary infrastructure, of which the Hong Kong-Zhuhai-Macao Bridge (HZMB) is one example. However, the construction industry has long been recognized as one of the most unsafe industries in the world. The safety performance of the HZMB-HK project is worse than that of other public works and the construction industry in general. This study aims to measure the safety performance of the HZMB-HK project and to identify preventive measures of the fatal accidents that occurred in this project, contributing to the body of knowledge on construction safety by examining accidents in large-scale infrastructure projects involving works carried out above or near the sea. The lessons from this study can help stakeholders, such as policy makers and practitioners, improve the safety performance of infrastructure projects worldwide.

Urban Positioning Infrastructure, Benefits and Challenges

Prof. Wu ChenProfessorDepartment of Land Surveying and Geo-InfromaticsThe Hong Kong Polytechnic University

AbstractPositioning, Navigation, and Timing (PNT) services are important for national security and economic developments. The US Department of Homeland Security (DHS) considers 13 of the 16 critical national infrastructure sectors to be critically dependent on PNT. All major countries like the US, China, Russia, and European countries are establishing their national PNT infrastructures, which are mainly based on Global Navigation Satellite Systems (GNSS) technologies. However, GNSS do not work well in urban environments, where satellite signals can be blocked by buildings. On the other hand, with the development of e-economics, the requirements of PNT services is even higher in cities to support diversified applications, such as autonomous vehicles, Mobility-as-a-Services. The Hong Kong government has recently published a Smart City Blueprint for Hong Kong and PNT infrastructure is deemed crucial for its development. This presentation will cover the new technologies for urban seamless positioning and the challenges ahead. The recent development of Hong Kong positioning infrastructures will also be covered.

Effective Design and Construction of Chinese High Strength S690 Steel in Buildings

Prof. Kwok-Fai ChungDirectorChinese National Engineering Research Centre for Steel Construction (Hong Kong Branch)The Hong Kong Polytechnic University

AbstractIn order to promote effective use of high strength steels in construction, a series of experimental and numerical investigations into the structural behavior of high strength S690 steels and their welded sections were conducted at the Chinese Engineering Research Centre for Steel Construction (Hong Kong Branch). This presentation reports key findings of these investigations, including the mechanical properties of S690 steels and their welded joints as well as the structural behavior of both stocky and slender columns of S690 welded H-sections, and partially restrained beams of S690 welded I-sections.

In general, the structural behavior of high strength S690 welded sections are demonstrated to follow closely to that of welded sections of normal strength S355 steels, and these include member buckling competing against material yielding in the presence of welding-induced residual stresses and geometrical initial out-of-straightness. Modern design rules such as EN 1993-1-1 & -12 are shown to be generally applicable to these S690 welded sections when suitably selected design data and parameters are employed. However, there are significant reductions on various mechanical properties of S690 welded joints after welding if heat input energy is not properly controlled.

The Research Needs on Air Quality and Health in the Greater Bay Area

Prof. Xiang-Dong LiAssociate Dean (Research)Faculty of Construction and EnvironmentThe Hong Kong Polytechnic University

AbstractRapid urban and industrial development has resulted in severe air pollution problems in developing countries such as China, especially in highly industrialized and populous urban clusters. Dissecting the complex mixtures of airborne particulate matter (PM) has been a key scientific focus in the last two decades, leading to significant advances in understanding physicochemical compositions for comprehensive source apportionment. However, identifying causative components with an attributable link to population-based health outcomes remains a huge challenge. The microbiome, an integral dimension of the PM mixture, is an unexplored frontier in terms of identity and functions in atmospheric processes and human health. In this study, we identify the major gaps in addressing these issues, and recommend a holistic framework for evaluating the sources, processes, and impacts of atmospheric PM pollution. Such an approach and the knowledge generated will facilitate the formulation of regulatory measures to control PM pollution in China and elsewhere.

Tackle Double Aging by Double Smart – from a Collaborative Research Perspective

Dr Calvin LukProject ManagerJockey Club Design Institute for Social InnovationThe Hong Kong Polytechnic University

AbstractPopulation and built environment aging are two intertwined issues that together comprise ‘Double-Aging’. It poses a potentially complex crisis which may challenge the role of Hong Kong as a global city in the Greater Bay Area (GBA). While the interplay of ageing population and buildings’ deterioration intensifies, these two aspects are commonly framed as independent realms by researchers and policy makers. Subsequently, existing research findings and proposed solutions are often found to be restrained or fragmentized by the dichotomy of ‘smart aging’ and ‘smart city’. As a result, there is a notable knowledge gap on what the combined effect of double-aging implies to cities and how different technologies can be consolidated to formulate smart solutions. DISI champions examining and tackling ‘double-aging’ from a strategic perspective by drawing on the wealth of applied research and expertise of PolyU. DISI attempts to introduce an integrated, people-centric ‘double-smart’ approach to leverage the synergy of smart aging and smart city in tackling the challenge and bring beneficial changes for the community.

Double-aging is an unavoidable trend for most developed cities worldwide. As a forerunner in tackling complex urban issues, Hong Kong may offer transferable knowledge and experiences for surrounding cities to ensure sustainable growth of the GBA in the face of double-aging in the foreseeable future.

Innovative Sensors and Machine Learning Algorithms for Monitoring-based Health Management of High-speed Railways

Prof. Yiqing NiDirectorNational Rail Transit Electrification and Automation Engineering Technology Research Center (Hong Kong Branch)The Hong Kong Polytechnic University

AbstractDeveloping smart rail systems by integrating sensing, communication, computing and information technologies is becoming an urgent need to satisfy the safety, punctuality and reliability requirements in the modern rail industry. Sensory systems have increasingly been a part of on railway systems, including rail infrastructure and trains for online and on-board monitoring to ensure their operational safety. In addition to innovative sensors, there is a need to develop advanced analytic tools for data-driven fault diagnosis and prognosis in a real-time manner. Probabilistic machine learning (PML) has emerged as one of the principal theoretical and practical approaches for designing ‘machines’ that learn from data acquired through sensing. In particular, probabilistic approaches developed in the framework of Bayesian machine learning (BML) provide an efficient means to interpret the heterogeneous monitoring data with diverse sources of uncertainty. Not only do they allow for the consideration of uncertainties inherent in monitoring data in characterization and modelling, they also enable the quantification of uncertainties in prediction and forecast. This presentation outlines innovative sensors and key BML methods that have been successfully utilized for fault diagnosis and prognosis of high-speed rail, including some recent collaborative research activities regarding rail transit in the Guangdong-Hong Kong-Macao Greater Bay Area.

Turning Waste Glass to Eco-friendly Construction Materials

Prof. Chi Sun PoonChair ProfessorDepartment of Civil and Environmental EngineeringThe Hong Kong Polytechnic University

AbstractIn Hong Kong, about 300 tonnes of waste glass are produced every day, representing a major fraction of the total solid waste stream. Only less than 10% of the waste is currently recycled. The disposal of the waste has become a severe social and environmental problem in the territory. Government sources have indicated that there are acute shortages of landfill space in Hong Kong. Hong Kong’s three mega landfills are expected to be full within 5 to 6 years’ time. The possibility of reducing and recycling the waste is thus of prime importance.

The Hong Kong Polytechnic University has been conducting research on methods to recycle waste glass. The potential applications of the recycled materials are in road pavements, concrete, concrete blocks and architectural mortars. Some of the developed techniques have been commercially utilized in industry. This presentation summarizes the major findings of the research conducted, and introduces some case studies on utilizing the waste materials in construction products in Hong Kong.

Fire Safety in Dense Urban Environments, Are We Meeting the Challenge?

Prof. Asif UsmaniHeadDepartment of Building Services EngineeringThe Hong Kong Polytechnic University

AbstractWith increasing migration to urban centres and the emergence of hyper-urban environments in many parts of the world, ideas such as smart cities are finding considerable traction. Demographic changes in terms of ageing populations mean that vulnerable citizens resident in older buildings that do not meet modern standards of fire safety may be exposed to unacceptable level of risk from fire. The Greater Bay area is inherently more sustainable because of the high density of population it achieves. Such an urban environment is an ideal candidate for smart city technologies to achieve greater sustainability. An increasing number of façade and vertically spreading fires in tall buildings around the world have shown that the evolution of the built environment has also changed the nature of the threat from fires. Consequently, urban environments are exposed to a greater risk, as prescriptive fire safety strategies are no longer fit for purpose. Firefighters are left facing an unpredictable hazard that they are neither trained for nor equipped to deal with, as the Grenfell Tower fire in London in 2017 has tragically demonstrated. This presentation will critically examine the aforementioned issues to answer the question posed in the title.

About the SpeakerProf. Usmani joined PolyU in August 2016. He was Professor of Structural Engineering and Computational Mechanics at the University of Edinburgh (UoE) until 2015. After a Master’s in structural engineering from Stanford and a few years in industry, he started his research career developing finite element codes for simulation of foundry casting processes at Swansea University involving molten metal flow, heat transfer and solidification. He initiated structural fire engineering research at UoE, establishing the University of Edinburgh as an internationally leading research centre in this field. Key achievements include fresh insights on non-intuitive structural behaviour observed in full-scale fire tests in a steel frame building at Cardington (UK) in the 1990s; explaining the collapse of WTC Twin Towers; proposing and leading research on a distributed real-time emergency response system, FireGrid, demonstrated successfully in London in 2010; developing open-source software OpenSees for modelling structures in fire, including multi-hazard response simulation. His research output consists of over 200 peer-reviewed publications resulting from research funding in excess of seven million pounds sterling. He will continue his research at PolyU with a renewed focus on real fires in tall buildings and the resilience of communities in dense urban environments such as Hong Kong.

Improving the Air Quality of the Greater Bay Area: Past Efforts and the Way Forward

Prof. Tao WangChair ProfessorDepartment of Civil and Environmental EngineeringThe Hong Kong Polytechnic University

AbstractAs one of the three most developed regions of China, Hong Kong and the adjacent Pearl River delta face great challenges to improve the air quality on both local and regional scales. Roadside pollution in Hong Kong remains serious owing to emissions of nitrogen oxides and particles from vehicles in addition to high-density buildings blocking wind flows. The whole smoggy region is characterized by high levels of ozone and particles from urban and industrial sources. Various mitigation measures have been implemented which have reduced atmospheric concentrations of some pollutants, but the ozone problem has not been improved due in part to the complexity of its source(s). More cooperation in research and control actions are needed in the Greater Bay Area. Hong Kong also should take more aggressive actions to reduce emissions from its vehicle fleets.

Monitoring a Flexible Barrier under Impact of Rock Fall and Debris Flow in Large-scale Physical Model Tests Using both FBG Sensors and Conventional Sensors

Prof. Jian-Hua YinChair ProfessorDepartment of Civil and Environmental EngineeringThe Hong Kong Polytechnic University

AbstractDebris flows in mountainous areas normally carry enormous kinetic energies and can cause catastrophic damages to human lives, buildings, and infrastructures in the affected areas. As a potential mitigation countermeasure, flexible barriers have been increasingly utilized to mitigate those disastrous and frequent natural geohazards. However, it is still an open question on how to design the flexible barriers economically and effectively to withstand the impact loads. In this talk, the speaker will introduce a large-scale physical modelling facility designed and built to perform experiments on rockfalls and debris flow impact. A dynamic monitoring system has been established to capture the dynamic responses of key components of a flexible barrier system during impacts of debris flows. A series of tests on the impact of rockfall and debris flow were conducted to investigate the deposition and interaction mechanisms of debris flows with a flexible barrier. Two high-speed cameras were used to track the motions and the interactions of the impact mass with the flexible barrier. Both conventional transducers and newly designed FBG (Fibre Brag Grating) sensors have also been used to monitor different parameters of the impact tests. Valuable test data were obtained from these tests using the high-speed cameras and sensors.

About the SpeakerProf. Yin received a BEng degree in 1983 in China, an MSc degree from the Institute of Rock and Soil Mechanics of the Chinese Academy of Sciences in 1984, and a PhD from The University of Manitoba, Canada, in 1990.
