The design of floor structures supporting human occupants is increasingly being governed by vibration serviceability criteria. This is a result of increasing slenderness of modern floor systems and the trend for fewer partitions and other non-structural elements that otherwise would provide damping. At the same time, demands for better vibration performance are increasing. Occupants of high quality commercial, residential and hospital buildings will complain when excessive levels of vibration are felt. Also, many new items of scientific, healthcare and manufacturing equipment are sensitive to even very low levels of vibration and the structures that support them must be designed to ensure an appropriate vibration environment.To address these issues, the proposed research will investigate the use of active vibration control (AVC) to improve the vibration performance of floor structures under human-induced loading. This technology has already been shown by the PI to be feasible but it requires substantial further research to be established as a practical option for structural engineers and building developers. Hence, the key aims of the proposed research are:- To identify and develop control strategies suitable for active control of human-induced vibrations in floors and to evaluate improvements in floor vibration performance through simulations, laboratory testing and field installation. A full spectrum of complexity will be investigated, ranging from simple single-input-single-output collocated systems to much more complex adaptive model-based systems using multiple sensors and actuators.- To develop inertial actuation technology appropriate for AVC on floor structures, and hence to demonstrate that an AVC system can be `packaged' to be affordable, compact, robust and reliable. These are key technological hurdles that must be addressed if the benefits of AVC systems are to be realised in the highly commercial civil engineering sector.

Even if climate change mitigation objectives agreed in Paris are met, sea level will rise at least by 0.3 to 0.6m in 2100 and then continue rising for centuries. The potential impacts for coastal flooding are a major source of concern for Europe because many infrastructures are located close to shorelines or in low-lying areas. Broad scale coastal climate services and platforms available today have successfully addressed the need to raise awareness on mitigation. However, an authoritative, consistent and decision oriented platform is still missing to meet the needs of adaptation practitioners concerned with (1) the routine identification of coastal territories at risk from innundation, (2) coastal land use planning or (3) maintaining coastal infastructure services. The Coastal Climate Core Service (CoCliCo) project aims at informing decision-making on coastal risk and adaptation, by delivering an open web-platform exploring dominant risk drivers, adjusting visualisation and analysis techniques to local decision contexts, and combining relevant and high-quality geospatial information layers. Through the platform, users will be able to visualize, download and analyse multiple decision-oriented coastal risk scenarios relevant to the rich user narratives of our Demonstration Case Studies addressing the three needs raised above. To meet this challenge, CoCliCo brings together European organizations and scholars that have proven track records of delivering broad-scale coastal risk and adaptation assessment, as well as leading research and technologies in interoperable geospatial data management, decision sciences and risk communication.

The CBES group at the UCL Bartlett School of Graduate Studies received its Platform Award in 2006 and the funding has facilitated a period of sustained success. Platform funding has been of critical value in helping us to retain key staff, to innovate and in providing the flexibility to be adventurous. We have also been able to enhance our knowledge exchange/transfer work and international collaboration. This has been reflected in the quality, growth and range of our activities. The Platform funding thus enabled us to establish a multi-disciplinary, world-leading research group which has dramatically increased in size, resulted in world leading academic publications, seeded a new Institute (Energy), developed new methods of interdisciplinary and systems working and won international prizes. CBES was submitted to and awarded the highest percentage (35%) of world leading rated researchers of any UK university in the 2008 Research Assessment Exercise (RAE) - Architecture and the Built Environment Panel. Building on the work directly supported or indirectly facilitated by the current Platform Grant, and also responding to new opportunities, the strategic direction of this continuation proposal represents a step change for CBES. During the period of the current Platform Grant, CBES was primarily interested in developing multi-disciplinary solutions to the practical problems of designing, constructing and managing environments within and around buildings. In the next quinquennium we will strengthen our world-leading position. We propose a strategic programme of activity in a timely new research direction - the unintended consequences of decarbonising the built environment . We aim to transform understanding of this urgent issue that will have enormous impact internationally.In order to predict the possible future states of such a complex socio-technical system, conventional scientific approaches that may have been appropriate for systems capable of being analysed into simple components are no longer applicable. Instead, we need to bring radically new approaches and ways of thinking to bear. We need to develop and extend our multi- and inter- disciplinary ways of working and be informed by modern complexity science. The initial Platform grant has helped set up a group that includes building scientists, heritage scientists, economists, systems modellers and social scientists. The renewal will enable the group to focus on this urgent problem, to develop appropriate research methods and help develop real-world solutions within the required timescale. The number of Investigators has increased from 11 at the start of the existing Platform Grant to 13 in the renewal - a vital expansion to enable the inclusion of a wider range of disciplines. Nevertheless, facilitated by Platform funding, we will now need to form a whole new set of additional alliances to support the development of our proposed work.One of the key achievements of the current Platform Grant has been the spinning off of the newly formed UCL Energy Institute (EI). CBES is thus ideally placed to benefit from the extensive and diverse range of energy demand reduction work at the EI. However, the EI is not funded to study unintended consequences and this Platform renewal will thus perfectly complement EI activity. Via Platform funding and in partnership with the EI, CBES aims to develop a new concentration of world-leading research excellence in this field. We will establish a regional hub for research collaboration with local universities which will ensure that benefits from Platform funding are felt more widely than UCL alone.

Globally, national infrastructure is facing significant challenges: - Ageing assets: Much of the UK's existing infrastructure is old and no longer fit for purpose. In its State of the Nation Infrastructure 2014 report the Institution of Civil Engineers stated that none of the sectors analysed were "fit for the future" and only one sector was "adequate for now". The need to future-proof existing and new infrastructure is of paramount importance and has become a constant theme in industry documents, seminars, workshops and discussions. - Increased loading: Existing infrastructure is challenged by the need to increase load and usage - be that number of passengers carried, numbers of vehicles or volume of water used - and the requirement to maintain the existing infrastructure while operating at current capacity. - Changing climate: projections for increasing numbers and severity of extreme weather events mean that our infrastructure will need to be more resilient in the future. These challenges require innovation to address them. However, in the infrastructure and construction industries tight operating margins, industry segmentation and strong emphasis on safety and reliability create barriers to introducing innovation into industry practice. CSIC is an Innovation and Knowledge Centre funded by EPSRC and Innovate UK to help address this market failure, by translating world leading research into industry implementation, working with more than 40 industry partners to develop, trial, provide and deliver high-quality, low cost, accurate sensor technologies and predictive tools which enable new ways of monitoring how infrastructure behaves during construction and asset operation, providing a whole-life approach to achieving sustainability in an integrated way. It provides training and access for industry to source, develop and deliver these new approaches to stimulate business and encourage economic growth, improving the management of the nation's infrastructure and construction industry. Our collaborative approach, bringing together leaders from industry and academia, accelerates the commercial development of emerging technologies, and promotes knowledge transfer and industry implementation to shape the future of infrastructure. Phase 2 funding will enable CSIC to address specific challenges remaining to implementation of smart infrastructure solutions. Over the next five years, to overcome these barriers and create a self-sustaining market in smart infrastructure, CSIC along with an expanded group of industry and academic partners will: - Create the complete, innovative solutions that the sector needs by integrating the components of smart infrastructure into systems approaches, bringing together sensor data and asset management decisions to improve whole life management of assets and city scale infrastructure planning; spin-in technology where necessary, to allow demonstration of smart technology in an integrated manner. - Continue to build industry confidence by working closely with partners to demonstrate and deploy new smart infrastructure solutions on live infrastructure projects. Develop projects on behalf of industry using seed-funds to fund hardware and consumables, and demonstrate capability. - Generate a compelling business case for smart infrastructure solutions together with asset owners and government organisations based on combining smarter information with whole life value models for infrastructure assets. Focus on value-driven messaging around the whole system business case for why smart infrastructure is the future, and will strive to turn today's intangibles into business drivers for the future. - Facilitate the development and expansion of the supply chain through extending our network of partners in new areas, knowledge transfer, smart infrastructure standards and influencing policy.
