Advances in technology are already transforming the way information is used by the supply chain at all stages of the construction process.
Digital Engineering encompasses a vast and growing area of study including everything from on-site automation and machine learning to exploring the use of computor vision, digital twins or satellite data to monitor infrastructure.
Project: Towards Data-centric Smart Infrastructures as Cyber-physical SystemsThe first project aims to identify the information need, model the data and prototype a digital twin of Staffordshire Bridges in collaboration with Microsoft and Network Rail. Didem's research further extends to develop a framework which aims to provide an information platform for digital twins and cyber-physical systems, including bridges, railways, roads, buildings and other similar assets. Didem uses systems thinking, design thinking and futures thinking to support stakeholders as they seek to identify the key data resources and information needed to better integrate different digital twins, where interoperable and sustainable decisions could be possible. For this purpose, Didem conducts interviews with partner organisations to support the framework. Additionally, Didem leads a study that is focused on planning future scenarios for the built environment of the UK in 2040 - together with a team of CDBB postdoctoral researchers. They work together to identify relevant trends and uncertainties (from people, mobility, infrastructure, technology, economy, government, and resources dimensions) and evaluate the intersection of these factors to build different scenarios. This study does not only use scenarios to initiate discussions on how the industry should act in rapidly changing, post-COVID19 world but also suggests strategies for enabling more sustainable future built environment. |

Project: Cloud-based Building Information ModellingBuilding Information Modelling (BIM) as a product and process enables stakeholders across the built environment sector to create digital versions of real world assets (such as buildings, bridges and tunnels). The digital versions are commonly called 'digital twins'. When placed on the cloud, the digital twins can serve as a resilient and integrated repository of all asset data throughout their life-cycle. Such a repository is a key enabler in this sector of all upcoming IT waves, such as cloud computing, data analytics, participatory sensing, and smart infrastructure. The potential benefits have attracted interest from a wide array of end-users whose interests span from early design phases to operation and asset management, and from roads and bridges to industrial off-shore facilities. This has led to aggressive market penetration in the last decade. However, the full potential of BIM is currently exploited only in a fairly narrow range of applications. This is mainly due to the lack of trained scientific personnel capable of understanding the value of BIM and creating the link between digital twins and possible applications. The ambition of CBIM is therefore to educate researchers in the development of a set of novel and disruptive BIM technologies that will automate the generation and enrichment of digital twins, improve the management, security and resilience of BIM-enabled processes, and boost the industrial uptake of BIM across sectors and disciplines by training these researchers to valorise and exploit their work. This new generation of researchers can play a key role in the widespread implementation of BIM products and processes dedicated to digitising our built infrastructure and managing our assets better to yield massive gains in sustainability, productivity and safety.

Project: Artificial Intelligence Optimised Pathways for Schedule ExecutionThe project seeks to develop a novel automated 'schedule learning platform' that applies data science and machine learning to thousands of previous project schedules, offering a unique scalable solution for improved certainty and confidence in project planning for future projects. The solution is based on thousands of previous construction projects, allowing the platform to learn across projects what was planned to happen and what actually happened, thus reducing the effect of human bias, subjectivity and inaccuracy. Schedule data is analysed, similar tasks and relationships are automatically grouped, with patterns drawn using Artificial Intelligence, enabling the platform to predict the most likely outcome for every task and provide optimal paths/recommendations to mitigate risks/delays.

Project: Interactive Point Cloud and Image Data Generation in Infrastructure ScenesAll construction trades and inspectors need spatial and visual data to operate. However, extracting up to thousands of measurements and creating meaningful registered data sets in a single work shift translates to a sizable portion of work time dedicated to measuring and processing instead of direct work. The research is mainly focused on increasing the efficiency of geometry and visual data collection by devising a system that tackles the challenges in data collection and post-processing through a combination of high-resolution DSLR cameras and a hand held laser scanner. Construction operatives and inspectors could benefit significantly from laser-scanner-quality data in terms of resolution and accuracy, with the mobility and reachability of hand held devices and the ability to operate outdoors reliably and from long distances. |

PhD Project: Automated BIM Generation of Existing and Under Construction RailwaysThis research is aimed at creating a viable approach to automate the generation of as-is geometric railway Building Information Modelling (BIM).The key novel idea that makes this possible is that railways follow a set of engineering design assumptions which can be used as guides for segmentation by Markov Chain Monte Carlo (MCMC) methods, region growing, or octrees. |

Project: Automatic Construction Monitoring Through Semantic Information ModellingThis project aims to develop computational algorithms and methods for automatic as-built construction monitoring through semantics-based Building Information Modelling (BIM). Construction as–built monitoring is crucial for the cost, time, quality and safety of projects. Methods for generating as-built status are primarily manual. There are gaps in sophistication of automation, and recognition for semantic construction information during the process is low. The project is expected to provide efficient and accurate solutions for as-built construction monitoring. The implementation of the as-build modelling approach will provide a significant tool to manage the status of construction project, including progress and quality tracking. [Further information] |
