For the past 6 years, the BIM World Congress has enabled all stakeholders in the construction, real estate and urban development sectors to share their experiences on the implementation of digital technology in their businesses and projects.

Beyond BIM, the uses of digital technology concern all types of players, from very small businesses to large groups and local authorities, whether they are just starting out or are already experts.

For the year 2021, 4 main thematic axes are developed:

• Construction 4.0: Designing more efficient structures with digital technology
• Building as a Service: Adding value to structures and developing new uses
• Environmental transition: supporting regulations and low-carbon objectives
• Smart Data: Digital infrastructures and service platforms

List of pre-themes 2021 as of December 15

Construction 4.0: Designing more efficient structures with digital technology

1. Modeling, design and BIM objects: organization of BIM object production, data enrichment, links with business tools, feedback
2. Design and geospatial integration of infrastructures: modelling infrastructures in their future environment, building and operating digital twins
3. Supply chain, traceability and industrialization of construction: organization of the digital continuum from the factory to the construction site, prefabrication, modular manufacturing
4. Building site 4.0 and connected infrastructures: connecting and managing building sites for greater safety, productivity and quality, integrating IoT into urban infrastructures
5. New trades: modernization of construction trades and new skills

Building as a Service: Adding value to structures and developing new uses

6. BIM-Operations and BIM-Management: optimizing building maintenance and operations with digital mock-ups
7. Smart Building and connected objects: Integrating BMS, IoT in Smart Building, interoperability and data platforms, link with digital models
8. Service approaches and Building as a Service: implementing BOS, managing buildings as resource centres, service platforms, business models
