The construction sector is strategically important to the UK economy, employing 3.1 million people (>9% of the workforce), producing £370 billion in turnover, and exporting more than £8 billion in products and services. However, its current philosophy is resource and cost inefficient and environmentally unsustainable, through its low productivity, slow technology adoption and tendency to demolish and rebuild. Metal 3D printing offers opportunities to solve these challenges and lead to a more productive, innovative and sustainable construction sector. Metal 3D printing technology has transformed other engineering disciplines, including the biomedical and aeronautical sectors, while its application within the construction sector is still in its infancy. The technology has been fundamentally proven through the MX3D Bridge, the first metal 3D printed structure that was opened in July 2021, however there are still a number of barriers preventing more widespread adoption. Current equipment and processes produce elements that have significant material and geometric variability, within the same build and between repeated builds, which is not optimal for real-world use. Furthermore, the limited availability of suitable printing equipment has prevented research into the development of this novel manufacturing technique and its applications to the construction sector. ICWAAM will be a globally unique metal 3D printing facility, dedicated to large-scale, cost-effective applications for the construction sector. It will offer new research capabilities into the printing process, automated manufacture and the repair and upgrade of our critical infrastructure, along with the printing of complex, materially efficient geometries, which are uneconomical or impossible with standard techniques. ICWAAM will fundamentally challenge the current philosophy of the construction industry and lead to its transformation into a more productive, innovative and sustainable sector, with increased worker safety. Without direct access to large-scale metal 3D printing equipment, such as ICWAAM, researchers are unable to undertake this critical research and development, to solve the longstanding challenges in the construction sector.

The strategic objective of this platform grant is to underpin Audio-Visual Media Research within the Centre for Vision, Speech and Signal Processing (CVSSP) to pursue fundamental research combining internationally leading expertise in understanding of real-world audio and visual data, and to transfer this capability to impact new application domains. Our goal is to pioneer new technologies which impact directly on industry practice in healthcare, sports, retail, communication, entertainment and training. This builds on CVSSP's unique track-record of world-leading research in both audio and visual machine perception which has enabled ground-breaking technology exploited by UK industry. The strategic contribution and international standing of the centres research in audio and visual media has been recognised by EPSRC through two previous platform grant awards (2003-14) and two programme grant awards in 2013 and 2015. Platform Grant funding is requested to reinforce the critical mass of expertise and knowledge of specialist facilities required to contribute advance in both fundamental understanding and pioneering new technology. In particular this Platform Grant will catalyse advances in multi-sensory machine perception building on the Centre's unique strengths in audio and vision. Key experienced post-doctoral researchers have specialist knowledge and practical know-how, which is an important resource for training new researchers and for maintaining cutting edge research using state-of-the-art facilities. Strategically the Platform Grant will build on recent independent advances in audio and visual scene analysis to lead multi-sensory understanding and modelling of real-world scenes. Research advances will provide the foundation for UK industry to lead the development of technologies ranging from intelligent sensing for healthcare and assisted living to immersive entertainment production. Platform Grant funding will also strengthen CVSSP's international collaboration with leading groups world-wide through extended research secondments US (Washington, USC), Asia (Tsinghua, Tianjin, Kyoto, Tokyo, KAUST) and Europe (INRIA, MPI, Fraunhofer, ETH, EPFL, KTH, CTU, UPF).
