Deployable flexible strips resembling carpenters' tape measures have been used to deploy and support devices such as antennas and solar panels for some time. These curved strips are often referred to as "booms", especially when they also act as structural members. Perhaps the most famous example was the Viking Lander soil collection arm, which could be reeled up or extended as required. These booms are usually constructed from thin curved sheets of metal, or laminates of fibre reinforced polymer. Some of these booms possess the property of "bistability", which means they do not need to be constrained once they have been coiled up. Flexible deployable booms have found other uses in deploying antennas and imaging systems on the battlefield, inserting monitoring equipment into nuclear power plants, deploying a flexible solar array from the International Space Station (ROSA experiment), and very recently in forming the masts of the InflateSail drag deorbiting sail: the first European sail to be deployed in space, and one of the first successful demonstrations of orbital debris removal technology. These booms have several advantages over deployable systems consisting of rigid links joined by hinges or sliders, including simplicity, a very small number of moving parts, and they often can be made to be very lightweight. However, two main limitations of these flexible booms are that the vast majority to those developed to date only deploy in a straight line, and that the exact geometry and deployed length of boom cannot be very accurately controlled. Recently, versions of these deployable booms that are not only curved in one direction (like a tape measure), but have "double curvature" have started to be studied in earnest. These booms can be deployed into a whole array of new shapes such as parabolas, a torus, and even helices. This opens up a number of new possible applications, such as lightweight deployable parabolic dishes, large tent supports, and as active elements in directional antennas. In our project, we will accelerate the technology readiness level (TRL) of this technology by developing the design and modelling tools required to work with doubly-curved deployable flexible booms (focussing mainly on fibre reinforced laminate materials), and improving the manufacturing methods and deployment mechanisms in an effort to make booms with the necessary geometric precision and dimensional stability to be used in RF and optical systems. To design these highly constrained flexible structures we will be adapting a very powerful equation solving technique called polynomial continuation to seek out the perfect laminate fibre angles and thicknesses to get the mechanical behaviour required. To model the behaviour of the booms we will be generating novel energy methods to predict coiled and deployed shapes, building on methods we have already developed in this field. To motivate the development of these technologies, the University of Surrey is partnering with Surrey Satellite Technology (SSTL) and RolaTube Technology Ltd. (RTL) to build two new devices making use of curved flexible deployable booms. With RTL we are constructing a directional helical antenna that unwinds from a small motorised hub, deploying its own ground plane at the same time. With SSTL we are developing a novel Earth imaging telescope barrel consisting of multiple curved strips which deploy simultaneously to form the outer barrel. The telescope strip is an especially interesting device because it requires a single curvature in the deployed state where it forms part of the barrel of the telescope, but quite a complicated double curvature when coiled into a ring around the base of the telescope.

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.

The increasing demand for low and zero carbon buildings in the UK has provided significant challenges for the energy intensive materials we currently rely on. At present somewhere between 20% and as much as 60% of the carbon footprint of new buildings is attributable to the materials used in construction; this is predicted to rise to over 95% by 2020. If the UK is to meet agreed 80% carbon reduction targets by 2050 it is clear that significant reductions in the embodied carbon of construction materials is required. What also seems clear is that current materials and systems are not capable of delivering these savings. The drive for an 80% reduction in carbon emissions, a decreasing reliance on non-renewal resources and for greater resource efficiency, requires step changes in attitude and approach as well as materials. Improvement in construction systems, capable of providing consistently enhanced levels of performance at a reasonable cost is required. Modern developments in construction materials include: eco-cements and concretes (low carbon binders); various bio-based materials including engineered timber, hemp-lime and insulation products; straw based products; high strength bio-composites; unfired clay products utilising organic stabilisers; environmentally responsive cladding materials; self healing materials; smart materials and proactive monitoring; hygrothermal and phase change materials; coatings for infection control; ultra thin thermally efficient coatings (using nano fillers); ultra high performance concretes; greater use of wastes; and, fibre reinforcement of soils. However, very few of these innovations make the break through to widespread mainstream use and even fewer offer the necessary step change in carbon reductions required A low carbon approach also requires novel solutions to address: whole life costing; end of life (disassembly and reuse); greater use of prefabrication; better life predictions and longer design life; lower waste; improved quality; planned renewal; and greater automation in the construction process. As well as performance, risk from uncertainty and potentially higher costs other important barriers to innovation include: lack of information/demo projects; changing site practices and opposition from commercial competitors offering potentially cheaper solutions.. A recent EPSRC Review has recognised the need for greater innovation in novel materials and novel uses of materials in the built environment. The vision for our network, LIMES.NET, is to create an international multi-disciplinary community of leading researchers, industrialists, policy makers and other stakeholders who share a common vision for the development and adoption of innovative low impact materials and solutions to deliver a more sustainable built environment in the 21st Century. The scope of LIMES.NET will include: adaptive and durable materials and solutions with significantly reduced embodied carbon and energy, based upon sustainable and appropriate use of resources; solutions for retrofitting applications to reduce performance carbon emissions of existing buildings and to minimise waste; climate change resilient and adaptive materials and technologies for retrofitting and new build applications to provide long term sustainable solutions. In recognition of their current adverse impacts and potential for future beneficial impacts, LIMES.NET will focus on bringing together experts to develop pathways to solutions using: renewable (timber and other plant based) construction materials; low-impact geo-based structural materials; cement and concrete based materials; innovative nano-materials and fibre reinforced composites. Through workshops and international visits the network will create a roadmap for multidisciplinary research and development pathways that will lead to high quality large research proposals, and an on-going virtual on-line centre of excellence.

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.
