eWork and eBusiness in Architecture, Engineering and Construction 2021 collects the papers presented at the 13th European Conference on Product and Process Modelling (ECPPM 2021, Moscow, 5-7 May 2021). The contributions cover a wide spectrum of thematic areas that hold great promise towards the advancement of research and technological development targeted at the digitalization of the AEC/FM (Architecture, Engineering, Construction and Facilities Management) domains. High quality contributions are devoted to critically important problems that arise, including:

• Information and Knowledge Management
• Semantic Web and Linked Data
• Communication and Collaboration Technologies
• Software Interoperability
• BIM Servers and Product Lifecycle Management Systems
• Digital Twins and Cyber-Physical Systems
• Sensors and Internet of Things
• Big Data
• Artificial and Augmented Intelligence in AEC
• Construction Management
• 5D/nD Modelling and Planning
• Building Performance Simulation
• Contract, Cost and Risk Management
• Safety and Quality
• Sustainable Buildings and Urban Environments
• Smart Buildings and Cities
• BIM Standardization, Implementation and Adoption
• Regulatory and Legal Aspects
• BIM Education and Training
• Industrialized Production, Smart Products and Services

Over the past quarter century, the biennial ECPPM conference series, as the oldest BIM conference, has provided researchers and practitioners with a unique platform to present and discuss the latest developments regarding emerging BIM technologies and complementary issues for their adoption in the AEC/FM industry.
About the Author:

1. Prof. Dr. Vitaly A. Semenov has headed the Department of System Integration and Multi-Disciplinary Applied Systems at the Ivannikov's Institute for System Programming of the Russian Academy of Sciences since 2015. His main research interests focus on model-driven software engineering methodologies and CASE toolkits for creating advanced digital platforms and integrated systems that meet the requirements of multi-functionality, multi-modality, scalability, interoperability, portability and deployment in heterogeneous environments. He has led more than 25 Russian and international R&D projects and has published 150 articles on fundamental topics of software engineering, data management, computer graphics, and operations research. He is a Professor for computer science at the Moscow Institute of Physics and Technology, and the Higher School of Economics both leading Russian State Universities. For more than 20 years he has been giving lectures on software and information visualization. Emerging BIM technologies are of particular attention. From 2007 to 2017 he directed the development of 4D modeling and planning system at Synchro Software Ltd. He developed innovative methods for spatial-temporal project planning, near-optimal project scheduling, effective rendering of large pseudo-dynamic scenes, and semantic reconciliation of replicated data, which made it possible to provide competitive advantages of the system. Currently, it is a popular software product that has been successfully used by hundreds of companies around the world to visually plan and manage complex construction projects and large infrastructure programs.

2. Prof. Dr.-Ing. Raimar J. Scherer is Senior Professor at the Institute of Construction Informatics at the Technical University Dresden responsible for the research. He was heading the Institute from 1994-2017. He has more than 35 years of experience in construction IT, including 7 years as full professor for CAD/CAM and structural reliabilty at the University of Karlsruhe and several years of practice in the construction industry including ICT consultancy and a one-year stay at a world leading CAD provider. His research activities include the broad spectrum of construction ICT aspects. He has been involved in 25 BIM related EU and 20 German research projects, out of which he co-ordinated 16. He is member of the multimodel group of ISO 21597 since 2017 and was member and vice chairperson of the building product model group in ISO 10303 from 1988 to 1999, the forerunner of IFC (ISO 16739). In 1994 he founded the first European BIM conference, the ECPPM. In 1999 he implemented the first BIM Server in Europe, based on the later standardized IFC building core model. He was founder and vice chairperson of the IFC-ST4 structural model group. He developed the simplified MVD/IDM method in 2012 and the multimodel method in 2014. In 2014 he received the ZUSE Medal, the annual highest Award for informatics in Germany. In 2015 he published a book on Information Management Systems in Construction, where the multi model was introduced in a consolidated way.
