One of the greatest challenges facing civil engineers in the 21st century is the stewardship of ageing infrastructure. Nowhere is this more apparent than in the networks of tunnels, pipelines and bridges that lie beneath and above the major cities around the world. Much of this infrastructure was constructed more than half a century ago and there is widespread evidence of its deterioration. Tunnels, particularly old ones, are prone to being influenced by activities such as adjacent construction, for instance piling, deep excavations and other tunnel construction. Excessive leakage and pipe bursts are frequent and usually unanticipated. Importantly, underground structures often cannot be inspected when they are being used by trains or due to other physical constraints. The fragility of old infrastructure also presents a challenge for new construction in congested urban environments. Little is known of the long-term performance of such infrastructure. These uncertainties and the importance of safety to users and consumers prompted the initiation of recent research projects investigating the prospect of damage detection and decision making and the use of novel materials to mitigate damage. Advances in the development of innovative sensors such as fibre optic sensors and micro electrical mechanical sensors (MEMS) offer intriguing possibilities that can radically alter the paradigms underlying existing methods of condition assessment and monitoring. Future monitoring systems will undoubtedly comprise Wireless Sensor Networks (WSN) and will be designed around the capabilities of autonomous nodes. Each node in the network will integrate specific sensing capabilities with communication, data processing and power supply. It is therefore the objective of this proposal to demonstrate how large numbers of sensors can be integrated into large-scale engineering systems to improve performance and extend the lifetime of infrastructure, while continuously evaluating and managing uncertainties and risks. This proposal is a joint project between the University of Cambridge and Imperial College London and comprises an integrated research program to evaluate and develop prototype WSN systems. The main objectives of this proposal are to bridge advances in modelling large-scale engineering infrastructure with advances in wireless sensor networks and to develop a low-cost smart sensing environment for monitoring ageing public infrastructure. Three application domains will be studied in detail: (i) monitoring water supply and sewer systems and (ii) monitoring tunnels and (iii) monitoring bridges. The complexity of the monitoring system requires the following research areas to be explored : sensor systems, wireless communications, autonomous systems, information management, programming and design tools, trust security and privacy, systems theory, human factors and social issues. Field trials will be carried out with London Underground Ltd., Thames Water, Highways Agency and Humber Bridge. Intel Corporation will support the project with hardware for the trials.

The economic and social well-being of society is dependent on the efficient performance of the nation's infrastructure which encompasses transport networks (roads, bridges, railways, tunnels, airports and canals), the energy sector (power stations, electricity and gas distribution networks), water supply and waste treatment facilities, buildings and also digital communications networks (telephone and internet). Much of this infrastructure is in a serious state of disrepair or reaching the end of its economic life (e.g. the first generation nuclear power stations) and governments have recognised the need for substantial investment to regenerate and expand the existing infrastructure as well as build new infrastructure to meet the challenges posed by increasing population and climate change. In addition to these requirements, a recent Infrastructure UK report suggests that the construction industry in the UK is less efficient and significantly more expensive than counterparts on the continent and overseas. It highlighted the need for a radical rethink of the entire industry which is often characterised as being 'old and slow' as opposed to the 'new and fast' technology sectors such as the aerospace and automobile industries. The fragmented nature of the overall supply chain, and the length of innovation cycle (20 years or more) have historically made industry transformation difficult to deliver. The industry also creates significant waste. Out of 420m tonnes of material consumed in the UK each year, an estimated 20% is thrown away. In 2008 the then Labour government set a series of challenging targets to improve sustainability in the construction sector. These include: (a) improve design; (b) promote innovation sustainability; (c) improve procurement and adopt whole life cycle principles; (d) increase training and reduce accidents; (e) achieve 50% reduction in construction waste to landfill by 2012; (f) reduce UK greenhouse gas emissions by at least 80% by 2050 and at least 34% by 2020 and (g) conserve water and enhance biodiversity on construction sites. Although some of these targets may be modified by the new government, it is likely that many will still be enforced and there remains a firm commitment to sustainable construction. On top of these targets, there is growing recognition that our infrastructure needs to be more resilient to the extremes of weather (such as floods and snow in the UK and hurricanes in Australia), and to the loads imposed by natural hazards such as earthquakes and tsunamis, as well as man-made events such as terrorist bombs and fires. All of these drivers serve to emphasise the importance of finding a mechanism to promote and implement the changes required. A 'business as usual' approach cannot be continued if these targets are to be achieved. The mission of the proposed Future Infrastructure Forum (FIF) is to generate a new vision of the shape of tomorrow's construction industry by providing a roadmap of research priorities in the ground and structural engineering sectors which will lead to firm proposals for innovative research aimed at revolutionizing how we procure, design and deliver major infrastructure projects. A key feature of this Forum is its broad membership which includes academics from over 20 of the top research Universities in the UK plus representatives from major consultants, contractors and industry and client organisations. In addition, a panel of experts from key international markets will be invited to participate and highlight the state-of-the-art and recent innovations across the globe. A core function will be to identify specific areas of focus and research projects which could be instigated immediately to precipitate this transformation. It will promote a total rethink of the fundamental approach to design, challenge established norms and stimulate innovation in construction.

Infrastructure is a large part of the UK's assets. Efficient management and maintenance of infrastructure are vital to the economy and society. The application of emerging technologies to advanced health monitoring of existing critical infrastructure assets will quantify and define the extent of ageing and the consequent remaining design life of infrastructure, thereby reducing the risk of failure. Emerging technologies will also transform the industry through a whole-life approach to achieving sustainability in construction and infrastructure in an integrated way - design and commissioning, the construction process, exploitation and use, and eventual de-commissioning. Crucial elements of these emerging technologies will be the application of the latest sensor technologies, data management tools and manufacturing processes to the construction industry, both during infrastructure construction and throughout its design life. There will be a very substantial market for exploitation of these technologies by the construction industry, particularly contractors, specialist instrumentation companies and owners of infrastructure.In this proposal, we seek to create the Innovation and Knowledge Centre for Smart Infrastructure and Construction that will bring together four leading research groups in the Cambridge Engineering Department and the Computer Laboratory (sensors, computing, manufacturing engineering and civil engineering), along with staff in other faculties - the Judge Business School and the Department of Architecture. The Centre will develop and commercialise emerging technologies which will provide radical changes in the construction and management of infrastructure, leading to considerably enhanced efficiencies, economies and adaptability. We propose to create 'Smart Infrastructure' with the following attributes: (a) minimal disturbance and maximum efficiency during construction, (b) minimal maintenance for new infrastructure and optimum management of existing infrastructure, (c) minimal failures even during extreme events (fire, natural hazards, climate change), and (d) minimal waste materials at the end of the life cycle. The IKC will focus on the innovative use of emerging technologies in sensor and data management (e.g. fibre optics, MEMS, computer vision, power harvesting, Radio Frequency Identification (RFID), and Wireless Sensor Networks). These will be coupled with emerging best practice in the form of the latest manufacturing and supply chain management approaches applied to construction and infrastructure (e.g. smart building components for life-cycle adaptive design, innovative manufacturing processes, integrated supply chain management, and smart management processes from building to city scales). It will aim to develop completely new markets and achieve breakthroughs in performance.The business opportunities in construction and infrastructure are very considerable, not only for construction companies but also for other industries such as IT, electronics and materials. The IKC is designed to respond directly and systematically to the input received from industry partners on what is required to address this issue. Through the close involvement of industry in technical development as well as in demonstrations in real construction projects, the commercialisation activities of emerging technologies will be progressed during the project to a point where they can be licensed to industry. The outputs of the IKC will provide the construction industry, infrastructure owners and operators with the means to ensure that very challenging new performance targets can be met. Furthermore the potential breakthroughs will make the industry more efficient and hence more profitable. They will also give UK companies a competitive advantage in the increasingly global construction market.
