COGITO: COnstruction-phase diGItal Twin mOdel

COGITO aims to speed up the digitalisation for lean construction as a steppingstone to achieve the industrialisation of the construction sector ('construction 4.0'). The COGITO solution comprises: i) an interoperable Digital Twin platform for semantic/ pragmatic alignment with services; ii) Reality capture tools will collect real-time data about the actual state and progress/evolution of the construction site; iii) Multi-source Data Stream Pre-Processing services will manage and semantically annotate big data streams to analyse complex data (e.g. drones, satellite images) to retrieve the necessary information about the actual status of the construction site and resources/ workers involved; iv) adaptive Workflow Management for visual progress monitoring of the construction site and optimal flow of information to relevant stakeholders; v) the Health & Safety service will analyse the nD BIM to pinpoint hazards and perform real-time alerting to prevent accidents based on live data from the site; vi) the Geometric and Visual Quality Control service will perform automated quality control checks through comparisons of as-is to as-designed BIM elements for verification of structure conditions and detection of geometric and visual defects; vii) the Digital Twin GUI will render the site 3D model – including static (as-designed BIM), quasi-static (as-built BIM) and dynamic information (e.g. asset, machinery, people locations); and viii) Workers On-site Guidance Applications will issue alerts to crews on site with information contextually relevant to their allocated tasks. The COGITO tool-box will be demonstrated in one lab facility in Austria and two real construction sites in Spain and Denmark to showcase its value and collect feedback for improvement from the field. Beyond technical activities, standardization activities will be carried out by two COGITO partners with strong links to the most important international standardisation bodies in this domain.
