Our infrastructure is central to the economic prosperity of the nation and to the flourishing of a stable, yet dynamic, civil society. Its interconnected strands - the energy, transportation, water, sanitation and communication networks that provide access to services and markets and which underpin the securities of daily life - must be not only affordable and reliable but also resilient against threats such as technological uncertainty, environmental causes, economic and political change, and demographic and societal change unfolding in an increasingly uncertain world. FIBE2 CDT will lead a paradigm shift in the approach to infrastructure resilience through the creation of an inspirational doctoral training programme for talented cohorts from diverse academic and social backgrounds to conduct world-class, cutting-edge and industry-relevant research. Our goal is to develop the infrastructure professionals of the future, equipped with a versatile and cross-disciplinary skillset to meet the most complex emerging challenges, harness the full value of existing infrastructure and contribute effectively to better infrastructure decision-making in the UK. The programme's technical focus will exploit high-level interconnected research themes in advanced infrastructure materials, rethinking design & construction, digitised civil engineering, whole-life performance, built environment and global challenges, along high-level crosscutting themes in emerging technologies, performance to data to knowledge, research across scales, and risk and uncertainty. In FIBE2 CDT we offer a radical rethink to deliver innovation for the cross-disciplinary and interconnected challenges in resilient infrastructure. Our 1+3 MRes/PhD programme proposes a new approach to infrastructure research where students from different disciplines proactively forge new training and research collaborations. FIBE2 is inspired by the paradigm of a 3D 'T' shaped engineer embodying a combination of depth and breadth of knowledge, augmented by our new thinking around cross-disciplinary training and research. High level Infrastructure Engineering concepts will be interlinked and related to the detailed technical fundamentals that underpin them in bespoke core and elective modules. Cohort-based learning will bridge across the wider environmental, societal, economic, business and policy issues within the even broader context of ethics, responsible innovation and ED&I. These depth and breadth elements are interwoven and brought together through problem-based challenges using large-scale cross-disciplinary infrastructure projects. Individual student plans will be carefully crafted to harmonise the specificity of PhD research with the need for expansive understanding of threats and opportunities. The development of Resilient FIBE2 CDT students with strong personal, technical and professional resilience attributes is integral to the FIBE2 approach to training and research. The FIBE2 PhD projects will build upon Cambridge's internationally leading research, investment and funding in the diverse areas related to infrastructure and resilience. Our major strategic initiatives include >£60M funding from EPSRC and industry. Our engagements in UKCRIC, CDBB, Alan Turing and Henry Royce Institutes and our world class graduate training programmes provide an inspirational environment for the proposed CDT. The FIBE2 vision has been co-created with our 27 strategic industry partners from across all infrastructure sectors and nine international academic centre partners across the world, who have pledged over £12M. We will work together to deliver the FIBE2 CDT objectives and add new dimensions to our students' experience. The lasting impact of FIBE2 will be embodied in our students acting as role models to inspire future generations of infrastructure engineers and rising to lead the profession through all the technological and societal challenges facing UK infrastructure.

Our vision is to transform the lives of displaced people encamped in extreme conditions through an engineered solution to housing that promotes a new science of shelter design. The project will entail research in five of the world's largest refugee camps. Zaatari and Azraq (Jordan), Kilis (Turkey), Mae La (Thailand), Nyarugusu (Tanzania). These have populations of up to 250,000 and hence are in many ways cities. They have summer temperatures >35degC and occasionally >40degC; in these conditions un-insulated dwellings are unable to provide safe conditions. In addition, such locations can have 1600W/m2 of solar radiation, further raising the temperature inside a dwelling, and in the case of Jordan winter temperatures of -10degC. In Thailand the high humidity is likely to be of equal importance in placing thermal stress on occupants. In addition, displacement shelters can use polymeric materials which contain a high proportion of VOCs such as plasticisers and release agents, and have poorly ventilated cooking facilities using fuels such as wood, thereby generating particulates. Camps were once expected to be a short term solution, and this is still true in some settings. However, as witnessed in numerous locations around the globe, encampment often continues for years or decades (for example, the 340,000 strong Dadaab camp in Kenya opened in 1992). Even in natural disasters delays in rebuilding can lead to displacement camps taking on aspects of semi-permanent settlement. The challenges of survival in the immediate onset of an emergency quickly give way to concerns about the suitability of shelter over a longer timeframe. Such basic dwellings inhibit domestic life, educational delivery to the young, and development of the social relations needed for community cohesion. Often the need of traumatised people for a sense of security and privacy also goes unmet. Unfortunately, even the state of the art in current shelter provision does not adequately consider building physics, thermal comfort and air quality. There is also a general lack of attention to socio-cultural issues. Thus, for example, our pilot study in Jordan has revealed through social surveys a consistent concern amongst the displaced population with the issues of safety and privacy. Given the diversity of potentially available building materials, climates and cultures, there will be no single shelter solution, but rather a need for a systematic process of design that is cognisant of the climate, landscape, culture, length of time the accommodation might be needed, flexibility as family size changes and portability. This project will develop such a design process by creating a new science of shelter design through engagement with aid agency staff in four countries with diverse weather, cultural conditions and political sensitivities. This will involve 1) wide scale social and indoor environment surveys in five camps; 2) the construction of a series of potential designs in the UK, in a climate chamber and in Jordan; and 3) the production of a multi-language, extreme climate building physics-based, culturally sensitive, shelter design tool for agency field staff.
