In spite of the global financial and economic crisis, a large number of plans for new railway networks is being proposed to meet the demand for both passengers and freight rail services. For example, construction has commenced on the £15.9 billion Crossrail project to provide an East-West rail link under London with 22 km of tunnels under the city. In January 2012 phase 1 of High Speed 2 (HS2) project was given government approval. The project will connect between London and Birmingham with future extensions to Leeds and Manchester. The overall cost of the line connecting between London and Birmingham is estimated between £15.8-17.4 billon. This will include substantial tunnelled sections through urban areas. Plans for light rail lines in urban areas are also progressing. In December 2011, plans to extend the Nottingham tram line where given green light by the government. The project involves 2 new tram lines with overall cost of £570m. In February 2012, Centro was given the green light to go ahead with the extension of Birmingham's Midland Metro tram service in a project worth £128 million. The introduction of surface and underground railways provides substantial reduction of pollution resulting from the use of trains powered by electricity and the reduction of number of cars on streets. The use of underground railways helps significantly with congestion problems in urban areas. One of the main environmental issues linked with railway transportation in urban areas is ground-borne vibration transmitting to nearby buildings. Ground-borne vibration from railways is generated at the wheel-rail interface due to the passage of individual wheels on tracks (quasi-static loading) and due to irregularities of wheels and tracks (dynamic loading). Vibration propagates to nearby buildings where it causes annoyance to people and malfunctioning of sensitive equipment. Inhabitants of buildings perceive vibration either directly, due to motion of floors and walls, or indirectly as re-radiated noise. Vibration can also cause disturbance due to movement of household objects, especially mirrors or due to rattling of windowpanes and glassware. The problem can be more serious in some circumstances, such as when an underground tunnel passes below sensitive buildings such as a concert hall. This project aims to develop a better understanding about key issues regarding the generation and propagation of railway vibration, namely the non-linear behaviour of tracks' elements and the dynamic soil-tunnel-pile interaction for a single as well as a twin tunnels. This will lead to improved models for the prediction of ground-borne vibration and noise from railways in order to reduce prediction uncertainty. To achieve the aim of the project, three objectives are set. The first is to investigate the effect of pre-load and non-linear behaviour of resilient elements of tracks will be investigated using excitation models (i.e. tracks on elastic foundations). The second is to develop a detailed Periodic Boundary Element model and couple that to the relevant structural elements to account for the interaction between twin-tunnels, soil and pile foundations. The third is to develop a fast running tool for calculating vibration transmitted to buildings on pile-foundation from surface tracks and from tracks in tunnels embedded in multi-layered ground. The model will be built in friendly-user software that will be made available for engineers responsible for designing of railway infrastructure and for engineers responsible for designing of measures to reduce vibration from railways. Note that the project does not aim specifically to address the issue of vibration from high speed trains running on soft soil but is focused rather on vibration and noise from trains in urban settings, principally in tunnels.

The Urban Living Birmingham (ULB) Consortium brings together the expertise of four universities; national and international academic institutions; and very many local, regional and national organisations. The core academic team, led by the University of Birmingham with Birmingham City University, Aston University and the University of Warwick, have world-leading track records in cities, engineering, services and social sciences; a portfolio of pioneering inter-disciplinary research; and a deep understanding of Birmingham and the West Midlands. On 20th November 2015 a meeting of 39 representatives from across Greater Birmingham's public, private and third sectors was held to discuss the Urban Living Partnership Pilot Call. Taking a city focus within the context of the region, this group noted that the appetite for innovation in the development and delivery of urban services was high in Birmingham, but the degree of success and ability to integrate these innovations into mainstream strategies and policies varied greatly. Therein lies the paradox and it became evident that there is a missed opportunity for Birmingham, and British cities more generally, to co-innovate by effectively drawing upon end-users. As the largest city in the UK outside London, with one of the most diverse and youthful populations anywhere in the UK, the City of Birmingham has the potential to set a new agenda for 21st century urban living. Like most great cities, Birmingham is experiencing disruptive change brought about in part by global economic forces combined with reductions in national and local public expenditure. Since the late 1960s, Birmingham has performed poorly on all economic indicators. In addition, in 2014 a review of the city's governance and the organisational capabilities of the city council noted that Birmingham had problems that were so significant that they were of national importance. This project identifies the diverse and interdependent challenges facing the City of Birmingham by the application of a rigorous diagnostic process based on the analysis of datasets informed by end-users and representatives from the public, private and third sectors. The focus is on the identification of opportunities for innovation in integrated and city-wide solutions that cut across traditional policy silos and that have the potential to transform the city into a prosperous, healthy and vibrant living place. The Urban Living Birmingham consortium aims to identify improvements to urban services by combining top-down urban governance with bottom-up lay and expert knowledge to provide an environment that emphasizes and encourages innovations that generate a step change in urban service provision. It will do this by bringing together, developing and applying end-user and open innovation processes (from business disciplines) and participatory and cooperative design principles (from urban design disciplines) to selected urban services and systems to co-create a resilient Birmingham that provides 'better outcomes for people'. Most transformational service innovations occur when service providers go beyond listening to consumers to co-innovating with consumers. This user-centric approach to innovation reflects a process of end-user innovation in which users can modify existing products and services, but also service providers can learn from this process. Urban Living Birmingham will contribute towards the transformation of Birmingham into a city that is a regional asset and a global beacon for urban service innovation; a city with an exceptionally rich quality of urban living, increased social cohesion, reduced deprivation, increased connectivity and productivity, and a healthy urban population.

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.
