Jakob Beetz graduated as a Dipl.-Ing. from Bauhaus-University Weimar in 2003 at the chair of Informatik in der Architektur InfAR, under the supervision of Prof. Dr.-Ing. Dirk Donath. He was awarded a PhD degree for his work on "Facilitating distributed collaboration in the AEC/FM sector using Semantic Web Technologies" supervised by prof. dr. ir. Bauke de Vries and Jos van Leeuwen at the ISBE group of the Department for the Built Environment at the TU Eindhoven.

He is author of more than 80 scientific peer-reviewed publications and co-editor and -author of the books Building Information Modeling - Technology Foundations and Industry Practice (English version, 2018) resp. Building Information Modeling - Technologische Grundlagen und industrielle Praxis (German, 2015).

He co-founded the Open Source collaboration platform and lay the foundations to the OWL representation of the Industry Foundation Classes (IFC) referred to as ifcOWL.

He has participated in numerous research projects including EU FP7 DURAARK, EU H2020 BIM4Ren and is active in committees for the standardization of interoperability in information exchange for the building industry on national (DIN), EU (CEN) and international (ISO, buildingSMART, W3C) levels.

Dr. Wim Gielingh will give the talks titled:

BIM: on the evolution of thought. A treatise from personal perspective and experience ;

About meaning: An introduction to the Theory of Notions

Dr Wim F Gielingh is owner and president of a company that develops sustainable business solutions for enterprises in the construction and manufacturing industries.Wim is one of the pioneers in the development of BIM. Between 1978 and 1984 he developed several intelligent 3D model based CAD/CAM applications for architecture, engineering and construction.

Between 1982 and 1988 he was also a member of CAM-I’s Geometric Modelling working group, which specified the procedural Application Interface Specification (AIS) for 3D modelers. The testbed for the AIS, Romulus, became later the standard kernel for many commercial geometric modelers, licensed under the names Acis and Parasolid. In 1986 Wim submitted the conceptual schema of his most recent modelling system as a contribution to the emerging ISO STEP standard, where it was accepted as the General AEC Reference Model (GARM). After the reshaping of STEP in 1990 GARM constructs moved to the Generic Integrated Resources of STEP, giving structure to many STEP Application Protocols and the IFC standard.

Between 1988 and 1995 Wim initiated several large European R&D projects on Product Data Technology and was manager of the IMPPACT and PISA projects. The latter project contributed to the reorganization of the German automotive industry in order to reduce the time-to-market of new car models. He was also (co)author of the chapters on Product Data Technology of the 3rd, 4th and 5th Framework Programs of ESPRIT (European Strategic Programme for Research on Information Technology). Motivated by the poor uptake of Product Data Technology in the building and construction sector, and the fact that this technology required new business processes, new skills and even new organizational structures, Wim decided in 1995 to become business consultant with a focus on business innovation and supply chain integration. He did projects for the automotive, mechanical, electronic, process and shipbuilding industries, in several cases resulting in a restructuring of the supply chain or new business offerings, such as in the form of product-as-a-service solutions. Amongst others, Wim directed between 1996 and 1999 the implementation of the Information Management and IT platform for NAM GLT, the first integrated Design-Build-Maintain construction project in Europe, with an overall budget of €3.5 billion, including a budget of €30 million for IM and IT.

During a sabbatical break in 2002-2005 he wrote a PhD thesis titled ‘Improving the Performance of Construction by the Acquisition, Organization and Use of Knowledge’, in which the foundation of Notion-theory was developed. Wim wrote over 50 scientific peer-reviewed papers, was keynote speaker on more than 20 international conferences, and was guest editor of the special issues on Product Data Technology (2008) and Product Lifecycle Knowledge (2010) of the International Journal of Computer Aided Design.

Pieter Pauwels will give the talk titled:

Information Exchange over the Web for the AEC Industry

Pieter Pauwels works as an Associate Professor at the Eindhoven University of Technology, the Department of the Built Environment. He previously worked at the Dept. of Architecture and Urban Planning at Ghent University (2008-2019). His work and interests are in information system support for the building life-cycle (architectural design, construction, building operation). With a lot of experience and knowledge in computer science and software development, he is involved in a number of industry-oriented research projects on topics affiliated to AI in construction, design thinking, Building Information Modelling (BIM), Linked Building Data (LBD), Linked Data in Architecture and Construction (LDAC), and Semantic Web technologies.

Dr. Thomas Krijnen will give the talk titled:

Content negotiation and the semantic schema

Thomas Krijnen is the maintainer of an open source software library for IFC building models, called ‘IfcOpenShell’. He has worked as a Senior Software Engineer for the software development and consultancy firm ‘Gehry Technologies’ where he was building the next generation platform for digital collaboration. Multi-disciplinary usage of building information and computational geometry have shaped his carreer since. Thomas is the founder of a company called ‘AECgeeks’ that specializes in research and development for the Architecture Engineering and Construction industry using open standards. He is a part-time PostDoc at Delft University (NL), after he completed his PhD dissertation on ‘Efficient storage and retrieval of detailed building models’ in 2019 at Eindhoven University (NL).

Silvia Meschini will give the talk titled:

Semantic Web and BPMN to set up a System of Digital Twin Prototypes

Silvia Meschini holds a Master Science in Building Engineer. She graduated in 2016 at Politecnica delle Marche and then she spent six months abroad as visiting scientist at the br2 of the TU in Munich, in particular dealing with “Advanced construction, Building Technology and BIM”. After that, she worked as research fellow at DICEA of Politecnica delle Marche, contributing at the development of a decision support system aimed at the management of large building stocks, based on BIM and Bayesian networks.
Then, she worked two years as a freelance engineer and she saw first-hand the evident difficulties that Italian Small Enterprises are facing in the digital transition. This strengthened her interest in research and new technologies, so that she decided to enroll a PhD to make her contribution for a more digitalized and productive Construction industry.
Starting from May 2020 she’s attending a PhD at BIM Group Lab of Politecnico di Milano. Her PhD is funded by a national interest research project aimed at developing an open-source, distributed, digital collaborative framework for Small and Medium Enterprises. She specifically focuses on the digital transition of process management by leveraging new digital approaches, web of data and process modeling.
