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.

Project Partners: Arup, Atkins, Canal & River Trust, Environment Agency, Geosense, High Speed Two, Highways England, ITM Monitoring, Kier, National Grid, Network Rail, Rail Safety & Standards Board, Scottish Canals, Transport Scotland. The Challenge: The development of the Proactive Infrastructure Monitoring and Evaluation (PRIME) system is driven by the increasing rate and severity of failures in flood defence, transportation, and utilities earthworks. This is due to aging assets (many canal and rail earthworks are over a hundred years old) and more extreme weather events (e.g. the extreme rainfall during winter 2013-14 & 2015-16). Asset failures are enormously expensive, costing hundreds of millions of pounds per year in the UK alone, not to mention risks to human health and disruption of transport systems, utilities and the wider economy. Assessment of the condition of geotechnical assets is essential for cost effective maintenance and prevention of hazardous failure events. Early identification of deteriorating condition generally allows low cost preventative remediation to be undertaken (post failure interventions are typically ten times more expensive) and reduces the risk of catastrophic failures. Conventional approaches to condition monitoring are often inadequate for predicting earthwork instability. They are heavily dependent on surface observations - i.e. walk-over surveys or airborne data collection. These approaches cannot detect the subsurface precursors to failure events; instead they identify failure once it has begun. There is growing recognition among infrastructure asset owners, managers, and consultants that automated monitoring technologies have the potential to reduce these costs and risks by providing continuous condition information and early warnings of failure. Aims & Objectives: The primary objective is to deliver a new remote condition monitoring and decision-support system for assessing the internal condition of safety critical geotechnical assets. This will be realised by implementing a fully automated software workflow for data analysis and information delivery, building upon the recently developed PRIME hardware platform. The integrated PRIME system (i.e. hardware & software) will combine emerging geophysical ground imaging technology with wireless telemetry, 'big data' handling, and web portal access. It will form the basis of a new generation of intelligent decision-support technology capable of 'seeing inside' vulnerable earthworks in near-real-time using diagnostic imaging methods routinely used in medical physics. By the end of this project, the software and hardware will be demonstrated to technology readiness level (TRL) 7 at new and existing stakeholder sites, ready for commercialisation and use by the wider stakeholder community. Benefits: The key benefits of PRIME to asset owners include cost savings through minimising unnecessary renewals and providing early warning of failure events, time savings associated with fewer manual site visits, and risk reduction by preventing dangerous earthworks failures, and minimising the need for people to enter potentially hazardous operational environments. Geotechnical monitoring providers, consultants & contractors will benefit through new cutting-edge geotechnical monitoring services and, for the first time, near-real-time volumetric subsurface monitoring information. Key Deliverables & Outputs: - New software to fully automate PRIME data processing and information delivery - including a web-based decision support dashboard. - Demonstration of the complete PRIME system at existing rail and waterways pilot sites, and new highways, power transmission and flood defence sites - establishing TRL 7 (demonstration in an operational environment). - A commercialisation strategy agreed with project partners to ensure technology translation to the stakeholder community.

Infrastructure systems such as water, transport and energy are vital to British society and the economy. It is very important that these systems are able to continue to function effectively in the future, but it is difficult to predict the conditions that they will need to operate under because of climate change, social change and economic changes. For this reason infrastructure needs to be adaptable and resilient, able to bounce back from whatever extreme events and general trends occur in the future. In order to achieve this infrastructure may look quite different to how it does today. We may have more renewable energy, more recycled water, and more public transport, walking and cycling, and our cities could look and operate quite differently as a result. Designing infrastructure for the future is a very complex task that needs to take into account the values, experiences and requirements of local communities and everyday people. Engineers and experts are good at developing technical solutions to well defined problems, but they have not been as successful at understanding the needs and expectations of local communities. Engineers have good methods for taking into account physical, enviromental and economic factors, but they need new tools to be able to better understand and account for social factors in their designs. Local communities will also have important roles to play in adapting to climate change and other uncertain events in the future, so it is important that local communities and engineers come together to decide what is important in designing future infrastructure. This fellowship will help Dr Sarah Bell to learn from good examples of how local communities can be involved in infrastructure decisions. Her research team will work with communities and engineers to define methods and tools to allow for better integration of community needs and ideas into infrastructure design. These tools and methods might include checklists or surveys to quickly understand what communities need and what they want for the future, calculators to help engineers working with communities to quickly calculate the environmental impacts and costs of different ideas for infrastructure, and risk assessments to understand the problems that might occur if communities are not involved in engineering design and the benefits that might be possible if they are.

Extreme weather causes damage to our infrastructure services such as energy supply, information and communications technology (ICT), transport, water supply, and more. Many of our infrastructure services are interdependent, and a failure in one sector leads to failure in other sectors. For example, failure of an electric substation due to extreme heat or flooding could lead to power cuts, reduced ICT services, and transport disruption because our road (eg. traffic lights) and railway networks need electricity to operate. Finding these infrastructure weak points that have a disproportionate impact across several infrastructure networks is essential for infrastructure resilience. Moreover, as our infrastructure has an operational lifetime of several decades or more we must act now to be prepared for future extreme weather. However, current adaptation plans are often done separately by each infrastructure sector (e.g. rail, ICT) and therefore by design do not consider infrastructure interdependencies. This proposal presents an alternative approach to adaptation planning that breaks down industry silos and uses H++ ("worst-case") extreme climate change scenarios. High emissions and H++ scenarios predict the equivalent of Mediterranean heat for Birmingham and the West Midlands in the future. This proposal will consider the impact that extreme heat would have on infrastructure of the region as a whole. Particularly, it will look for weak points that could cause multiple failures across several infrastructure sectors. The project will use best-practice examples of heat-resilient infrastructure from Mediterranean cities to identify potential adaptation strategies that could be used in the Midlands. Best practice examples will be those that deliver long-term sustainability and multiple benefits, such as urban greening, which can provide climate regulation to build heat resilience, but also improve air quality, provide sustainable urban drainage, and positively influence health and well-being. The weakest infrastructure links and examples of best practice will be shared with infrastructure operators/owners to facilitate holistic, evidence-based adaptation planning. The adaptation approach can be used in other cities and for other extreme weather types. Guidance documents will be created so the method can be applied nationally and internationally in different situations and regions. The library of best practice examples of sustainable heat-resilient infrastructure and heat adaptation measures will be available online for global dissemination. This proposal specifically addresses the LWEC challenge by applying a system-of-systems approach to develop heat resilient infrastructure at a city and regional scales. Birmingham is an excellent demonstrator; HS2 and the new terminus station will arrive in the city by 2026. 51,000 new homes are required for the growing population. It also faces multiple challenges that will be exacerbated by extreme heat including increasing demand for electricity and utilities, an urban heat island effect, and transport networks which are currently operating at capacity. Now is the time for effective adaptation planning before long-term decisions and irreversible infrastructure development are undertaken. Crucially, as the West Midlands moves to devolved government there is the opportunity for leading regional research like this to shape governance plans. Dr Emma Ferranti undertakes challenge-led research in urban climatology and infrastructure meteorology. She holds a NERC Knowledge Exchange Fellowship with networks including infrastructure operators, local authorities, planners, and professionals passionate about urban-greening. This Fellowship will enable her to establish a new multidisciplinary research area in decision-centric adaptation planning that utilises research excellence from the Schools of Engineering, and Geography, Earth and Environmental Science at the University of Birmingham.

Train speeds have steadily increased over time through advances in technology and the proposed second UK high speed railway line (HS2) will likely be designed with "passive provision" for future running at 400 km/hour. This is faster than on any ballasted track railway in the world. It is currently simply not known whether railway track for speeds of potentially 400 km/hour would be better constructed using a traditional ballast bed, a more highly engineered trackform such as a slabtrack or a hybrid between the two. Although slabtrack may have the advantage of greater permanence, ballasted track costs less to construct and if the need for ongoing maintenance can be overcome or reduced, may offer whole-life cost and carbon benefits. Certain knowledge gaps relating to ballasted track have become apparent from operational experience with HS1 and in the outline design of HS2. These concern 1. Track Geometry: experience on HS1 (London to the Channel Tunnel) is that certain sections of track, such as transition zones (between ballasted track and a more highly engineered trackform as used in tunnels and on bridges) and some curves require excessive tamping. This results in accelerated ballast degradation and increased ground vibration; both have an adverse effect on the environmental performance of the railway in terms of material use and impact on the surroundings. Thus the suitability of current design rules in terms of allowable combinations of speed, vertical and horizontal curve radius, and how these affect the need for ongoing maintenance to retain ride quality and passenger comfort is uncertain. 2. Critical velocity: on soft ground, train speeds can approach or exceed the speed of waves in the ground giving rise to resonance type effects and increased deformations. Instances of this phenomenon have been overcome using a number of mitigation measures such as the rebuilding of the embankment using compacted fill and geogrids, installation of a piled raft and ground treatment using either deep dry soil mixing or controlled modulus columns. The cost of such remedial measures can be very high, especially if they are taken primarily on a precautionary basis. However, many methods of analysis are unrefined (for example, linear elastic behaviour is often assumed or the heterogeneity of the ground, track support system and train dynamics are neglected), and conventional empirical methods may significantly overestimate dynamic amplification effects. Thus there is scope for achieving considerable economic benefits through the specification of more cost effective solutions, if the fundamental science can be better understood. 3. Ballast flight, ie the potential for ballast particles to become airborne during the passage of a very high speed train. This can cause extensive damage to the undersides of trains, and to the rails themselves if a small particle of ballast comes to rest on the rail and is then crushed. Investigations have shown that ballast flight depends on a combination of both mechanical and aerodynamic forces, and is therefore related to both train operating conditions and track layouts, but the exact conditions that give rise to it are not fully understood. The research idea is that, by understanding the underlying science associated with high speed railways and implementing it through appropriate, reasoned advances in engineering design, we can vastly improve on the effectiveness and reduce maintenance needs of ballasted railway track for line speeds up to at least 400 km/h.
