Civil infrastructure is the key to unlocking net zero. To achieve the ambitious UK targets of net zero by 2050, we require innovative approaches to design, construction, and operation that prioritise energy efficiency, renewable resources, and low-carbon materials. Meeting net zero carbon emissions will require not only significant investment and planning, but also a radical shift in how we approach the design and management of our civil infrastructure. Reliable low carbon infrastructure sector solutions that meet real user needs are essential to ensure a smooth and safe transition to a net zero future. To address these challenges, the UK must develop highly skilled infrastructure professionals who can champion this urgent, complex, interconnected and cross-disciplinary transition to net zero infrastructure. This EPSRC Centre for Doctoral Training in Future Infrastructure and Built Environment: Unlocking Net Zero (FIBE3 CDT) aims to lead this transformation by co-developing and co-delivering an inspirational doctoral training programme with industry partners. FIBE3 will focus on meeting the user needs of the construction and infrastructure sector in its pursuit of net zero. Our goal is to equip emerging talents from diverse academic and social backgrounds with the skills, knowledge and qualities to engineer the infrastructure needed to unlock net zero, including technological, environmental, economic, social and demographic challenges. Achievable outcomes will include a dynamic roadmap for the infrastructure that unlocks net zero, cohort-based doctoral student training with immersive industry experience, a CDT which is firmly embedded within existing net zero research initiatives, and expanded networks and outward-facing education. These outcomes will be centred around four thematic enablers: (1) existing and disruptive/new technologies, (2) radical circularity and whole life approach, (3) AI-driven digitalisation and data, and (4) risk-based systems thinking and connectivity. FIBE3 doctoral students will be trained to unlock net zero by evolving the MRes year to include intimate industry engagement through the novel introduction of a fourth dimension to our successful 'T-shaped' training model and designing the PhD with regular outward-facing deliverables. We have leveraged industry-borne ideas to align theory and practice, streamline business and research needs, and provide both academic-led and industry-led training activities. Cohort-based training in technical, commercial, transferable and personal skills will be provided for our graduates to become skilled professionals and leaders in delivering net zero infrastructure. FIBE3's alignment with real industry needs is backed by a 31 strong consortium, including owners, consultants, contractors, technology providers and knowledge transfer partners, who actively seek engagement for solutions and will support the CDT with substantial cash (£2.56M) and in-kind (£8.88M) contributions. At Cambridge, the FIBE3 CDT will be embedded within an inspirational research and training environment, a culture of academic excellence and within a department with strategic cross-cutting research themes that have net zero ambitions at their core. This is exemplified by Cambridge's portfolio of over £60M current aligned research grant funding and our internationally renowned centres and initiatives including the Digital Roads of the Future Initiative, the Centre for Smart Infrastructure and Construction, Cambridge Zero and Cambridge Centres for Climate Repair and Carbon Credits, as well as our strong partnerships with UK universities and leading academic centres across the globe. Our proposed vision, training structure and deliverables are exciting and challenging; we are confident that we have the right team to deliver a highly successful FIBE3 CDT and to continue to develop outstanding PhD graduates who will be net zero infrastructure champions of the future.

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.
