duality between bim and gis an example related to the medieval bridge azzone visconti

The paper presents the work carried out on the medieval bridge Azzone Visconti in Lecco, Italy. The project required the use of both BIM and GIS technologies to assess the loading capacity of the bridge. First, a detailed geometric survey was carried out with laser scanning and photogrammetric techniques. The aim was the generation of a BIM. Displacements were then measured via geometric levelling during loading tests carried out in different days. Such data were integrated and stored in the BIM. Finally, the simulation of traffic conditions was used to investigate the usability of the BIM for a geographic area around the bridge. Results highlighted that the BIM used in the first stage of the work had to be replaced with another integrated BIM-GIS solution more suitable for analysis based on geospatial data

Collaborative multi-scale 3D city and infrastructure modeling and simulation

Computer-aided collaborative and multi-scale 3D planning are challenges for complex railway and subway track infrastructure projects in the built environment. Many legal, economic, environmental, and structural requirements have to be taken into account. The stringent use of 3D models in the different phases of the planning process facilitates communication and collaboration between the stake holders such as civil engineers, geological engineers, and decision makers. This paper presents concepts, developments, and experiences gained by an interdisciplinary research group coming from civil engineering informatics and geo-informatics banding together skills of both, the Building Information Modeling and the 3D GIS world. New approaches including the development of a collaborative platform and 3D multi-scale modelling are proposed for collaborative planning and simulation to improve the digital 3D planning of subway tracks and other infrastructures. Experiences during this research and lessons learned are presented as well as an outlook on future research focusing on Building Information Modeling and 3D GIS applications for cities of the future

Proceedings of the 29th EG-ICE International Workshop on Intelligent Computing in Engineering

This publication is the Proceedings of the 29th EG-ICE International Workshop on Intelligent Computing in Engineering from July 6-8, 2022. The EG-ICE International Workshop on Intelligent Computing in Engineering brings together international experts working on the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolution of challenges such as supporting 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. &nbsp

Repräsentation und Detaillierung parametrischer Skizzen mit Hilfe von Graphersetzungssystemen

Im Bereich der Infrastrukturplanung ist es sinnvoll, Produktmodelle in verschiedenen sogenannten Levels of Detail (LODs) also als mehrskaliges Modell darzustellen. Um dies zu ermöglichen, sind Überlegungen zum Aufbau von konsistenzwahrenden Repräsentationen dieser Modelle in allen LODs notwendig. Daher sollen in dieser Arbeit erste Untersuchungen zur Automatisierung der entsprechenden Detaillierungsvorgänge durchgeführt werden. Diese Arbeit beschäftigt sich dabei mit der für diesen Ansatz grundlegenden Fragestellung, wie zweidimensionale parametrische geometrische Modelle (Skizzen) durch Graphen und die Detaillierung dieser Modelle durch entsprechende Graphersetzungsregeln dargestellt werden können. Als Grundlage dient dabei die Theorie der Graphersetzungssysteme und der parametrischen Modellierung. Es wird dafür erarbeitet, wie sich eine Skizze durch einen Graphen prinzipiell repräsentieren lässt und welche Einschränkungen dabei beachtet werden müssen. Durch die Entwicklung eines Software-Tools ist es zusätzlich möglich, die durch den erstellten Graphen repräsentierte Skizze in einer parametrischen Modellierungssoftware (Autodesk Inventor) anzeigen zu können. Die Überlegungen werden durch die Erstellung eines Prototyps überprüft, der die Skizze eines Tunnelquerschnitts in einzelnen Schritten aufbaut bzw. detailliert
