Digital Twinning for the Built Environment
Wednesday, 13th July 2022, 18:00-19:30, Vorhoelzer Forum
Digital Twinning methods can produce a reliable digital record of the built environment and enable owners to reliably protect, monitor and maintain the condition of their asset. The built environment is comprised of large assets that need significant resource investments to design, construct, maintain and operate them. Improving productivity, i.e., efficiency and effectiveness, and creating new, disruptive ways to address existing problems throughout their lifecycle can generate significant performance improvements in cost, time, quality, safety, sustainability, and resilience metrics for all involved parties. Creating and maintaining an up-to-date electronic record of built environment assets in the form of rich Digital Twins can help generate such improvements. This talk introduces research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting Digital Twin, automatically extracting defect spatial measurements, and sensor and sensor data modelling. The results of these methods are further exploited through their application in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage.

Ontologies and linked data: applicability and technology review
Friday, May 13th 2022, 09:45, Vorhoelzer Forum
Linked data and ontologies are often named in the AEC sector as a new set of technologies with lots of potential for connecting different data sets and enabling inference with these data. References are typically made to RDF graphs and OWL ontologies in this regard. While that potential exists, these languages are also simply part of a larger ecosystem of technologies (e.g. SQL, JSON, ML, NLP, etc), in which many other data are also connected, or 'linked', and in which ontologies have been available for many years; albeit in different languages. In this talk, the RDF graph data model and OWL ontologies are explained in detail, and their position in relation to several other valuable technologies is presented, which leads to a better understanding of their applicability in our AEC domain.

Automatically generating structured information on the as-is status of facilities from visual data
Monday, July 22nd 2019, 16:15 Uhr, Vorhoelzer Forum
Despite the large production and collection of digital data, the AEC/FM industry lacks accurate, detailed, consistent and up-to-date knowledge of facilities. Advances in sensing technology allow the acquisition of high-fidelity 3D digital replicas of the as-is status. However, the output of such systems does not provide information on the spatial components, attributes and in-between relationships, thus cannot support downstream tasks (e.g., construction progress monitoring, maintenance activities, etc.). In this talk I will describe recent work on the automated extraction and knowledge-based representation of this information from visual data using Machine Vision and AI, as well as how it improves existing processes and enables novel workflows.

Automated Approaches towards BIM-based Intelligent Decision Support in Design
16. Januar 2019, 19:00 Uhr, Vorhoelzer Forum
The architecture, engineering, construction and facility management (AECFM) industry has been experiencing many changes since inexpensive networked, mobile computing devices have become ubiquitous. With the rising amount of information and data generated in the life cycle of capital projects, information modeling and data interoperability have become a critical element in design, engineering, construction, and maintenance of capital facilities. Recent advances in Visualization, Information Modeling, and Simulation (VIMS) have the potential to address a number of these pressing challenges. The objective of this talk is to discuss challenges and ongoing research in three areas of study in VIMS: capturing experiential knowledge in building information modeling (BIM)-based design coordination; 4-dimensional modeling for site-specific safety planning; and automating the BIM upkeep process in the facility operations phase leveraging deep learning and computer vision.

Scan-vs-BIM for Construction Control
12. Dezember 2018, 18:00 Uhr, Oskar-von-Miller Forum
When Laser Scanning and Building Information Modelling (BIM) technologies were emerging, the construction industry showed signifi cant interest in what were to be eventually called “Scan-to-BIM”: the process of using a laser scanned point clouds to develop BIM models of existing assets. However, with the use of BIM for design, another important use of these technologies is what some of us have called “Scan-vs-BIM”: the comparison of laser scanned point clouds (capturing the as-is states of constructions) to BIM models (representing the as-designed states of constructions). Scan-vs-BIM offer signifi cant opportunities for further automation in construction project delivery for example for progress or quality control. This talk will present the Scan-vs-BIM concept, illustrate its process and benefi ts. The talk will then expand on the subject of using the output of Scan-vs-BIM processing to enhance dimensional quality control with a view to evolve dimensional quality control from a traditionally point-based measurement process to a surface-based measurement process.

BIM for Europe
The economic benefits of digitalization are well recognized. The wider use of technology, digital processes, automation and higher-skilled workers contribute greatly to Europe’s economic, social and environmental future. The European construction sector is undergoing its own digital revolution: Building Information Modelling (BIM) represents the construction sector’s moment of digitalization. Since February 2016 Europe is host to the greatest regional concentration of government-led BIM programmes in the world. The "EU BIM Task Group", formed in 2016 and co-funded by the European Commission, has over 20 European member states with representatives of public procurers, public building and infrastructure owners and policy makers. It aims to bring together these national efforts into a common and aligned European approach to develop a world-class digital construction sector.

The 3D Modeling of Interiors featuring Combinatorics and Stochastics
Three-dimensional urban and building models in the sense of CityGML capture the geometry, represent the structure and semantically model relevant components such as doors, windows and balconies.
Building Information Models are models for supporting building planning, construction and facility management. They also represent those objects that are not observable from the outside.
The three-dimensional modeling of interior spaces forms a "missing link" between both worlds. Their geometrical detection is complex and difficult. Laser scanners or image-based processes require that every single room must be entered. In addition, the way from the 3D point cloud to the interior model is methodically sophisticated and requires that furniture is identified and "calculated". We present an approach that requires no additional geometry acquisition inside buildings.
The “digital transformation” has become a widely discussed topic – even in the construction sector, where digital methods play an increasingly important role in planning and in the construction work itself. However, the direct connection between “Building Information Modeling” (BIM) and computer-controlled construction work is still a construction site itself. There are still too many fault locations in the digital process.
The German-Swiss office Design-To-Production has been designing digital process chains from design to production for ten years now – successfully. The interdisciplinary team around the architect Arnold Walz and the computer scientist Fabian Scheurer helps architects, engineers, and construction companies to bridge the gap between the idea and its realization, consequently relying on digital modeling and computer-controlled production processes. Once, technologies like this were mainly needed for geometrically complex building projects such as the Centre Pompidou in Metz (Shigeru Ban) or the Mercedes Benz Museum (UN Studio), but they are now also of interest for standard construction projects. For an efficient implementation, however, there have to be new processes in the field of planning and construction: Beyond BIM.
