Centre for Digital Built Britain completed its five-year mission and closed its doors at the end of September 2022. This account remains as a legacy of the achievements of our five-year foundational journey towards a digital built Britain. -- The Centre for Digital Built Britain was a partnership between the Department of Business, Energy & Industrial Strategy and the University of Cambridge. It sought to understand how the construction and infrastructure sectors can use a digital approach to better design, build, operate and integrate the built environment. The Centre was established by HM Government in the 2017 Autumn Budget as the home of the UK BIM and Digital Built Britain Programmes. The Centre's founding mission was 'to develop and demonstrate policy and practical insights that will enable the exploitation of new and emerging technologies, data and analytics to enhance the nature and built environment, thereby driving up commercial competitiveness and productivity, as well as citizen quality of life and well-being.'
