Granularity in visualisation of 3D BIM models design-science approach

Building Information Modeling (BIM) has gradually grown into one of the key information management platforms in the Architecture, Engineering and Construction industry. With the growing amount of information in and outside the digital construction industry, concepts of information retrieval like relevance and granularity have become relevant in this domain. An increased need for interoperability and easy access to information has caused the industry to look towards concepts like the semantic web and linked data. But within all this, the geometrical visualisation, which is an integral part of the BIM process, has lagged behind on the front of granularity and still seems to be done mainly using the conventional ways. We try to explore ways to introduce granularity in the visualisation of 3D BIM models, and connecting it to the semantic information which is already granular, thus creating a mapping between the two at a granular level. A web-based prototype is implemented and analysed as a proof of the presented concept, with the semantics being represented inside a graph-based data structure. We further present a discussion on the potential applications and use cases of the conceptualised framework in the field of construction and building lifecycle management. The work aims to take the first step towards modularising the visualisation process, and has tried to pave the way for detailed analyses and further improvements that may follow in this direction

Training of Crisis Mappers and Map Production from Multi-sensor Data: Vernazza Case Study (Cinque Terre National Park, Italy)

This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

EG-ICE 2021 Workshop on Intelligent Computing in Engineering

The 28th EG-ICE International Workshop 2021 brings together international experts working at the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolutions to support multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research. Competence and knowledge transfer goes both ways

A knowledge based approach to integration of products, processes and reconfigurable automation resources

The success of next generation automotive companies will depend upon their ability to adapt to ever changing market trends thus becoming highly responsive. In the automotive sector, the assembly line design and reconfiguration is an especially critical and extremely complex job. The current research addresses some of the aspects of this activity under the umbrella of a larger ongoing research project called Business Driven Automation (BDA) project. The BDA project aims to carry out complete virtual 3D modeling-based verifications of the assembly line for new or revised products in contrast to the prevalent practice of manual evaluation of effects of product change on physical resources.
