Dynamic BIM IFC updates: enhancing project efficiency with GIS integration in a CDE

The dynamic integration of BIM and GIS is transforming the Architecture, Engineering, and Construction (AEC) sector. Leveraging the openBIM IFC format within a Common Data Environment (CDE), changes made to BIM models are seamlessly updated in GIS systems. This innovative approach ensures that property and infrastructure data remains current across a territorial scale. Discover how this advancement is reshaping the industry!

A new chapter for geospatial Digital Twins

The integration between BIM and GIS opens the doors to a new era for geospatial digital twins.

A geospatial digital twin is a virtual model, a 3D reconstruction of an environment, asset, building, infrastructure, etc., which also includes a series of location information about the position the asset occupies in space.

GIS technology allows for creating an exact replica of the physical environment and the complete territorial and geographical context including buildings, roads, bridges, etc.

The BIM model, on the other hand, contains a vast amount of information on every aspect of the property or infrastructure, useful for its entire lifecycle. The information is not only geometric (derived from the 3D representation) but constitutes a set of customizable data that can be implemented by the user over time, based on the purpose of the 3D representation.

The goal is to effectively manage any type of design, construction, maintenance, and demolition intervention on the asset.

By combining GIS data with BIM data, the result is the geospatial digital twin, an integrated model that provides a complete view of the current state of the project, enabling informed decisions on investments and infrastructure development, and potentially preparing to address potential issues and adopt appropriate corrective measures.

These digital twins allow for an accurate and updated virtual representation of the real world, facilitating infrastructure management and maintenance. The ability to view real-time changes made to BIM models within the geographic context of GIS offers significant added value, improving the efficiency and precision of operations.

The key to this innovation lies in the use of the Industry Foundation Classes (IFC) format, an open standard for BIM data exchange, within a Common Data Environment (CDE). IFC facilitates interoperability between different software platforms, allowing users to modify the BIM model within the CDE. The changes made are immediately reflected in the GIS, ensuring that all territorial information is constantly updated.

Advantages of BIM-GIS integration

The integration of BIM models and GIS systems ensures added value in asset management, not only in the design phase but throughout its lifecycle. Here are the main advantages:

• Dynamic updates: GIS maps can be enriched with georeferenced BIM models, creating even very complex and extensive geospatial digital twins in a single working environment. In this case, any changes made to the BIM model are automatically transferred to the GIS map. This process eliminates the need for manual updates, reducing the risk of errors and ensuring that the data is always accurate and up-to-date;
• Operational efficiency: The integration of BIM and GIS optimizes infrastructure planning and management processes. Professionals can make more informed and timely decisions thanks to the availability of complete and updated data;
• Sustainability: The integration facilitates sustainable design, taking into account environmental and geographical factors from the early stages of the project;
• Collaboration: Multidisciplinary teams can collaborate more easily, sharing information through a common platform;
• Territory management: The ability to visualize and analyze territorial data in real-time facilitates resource management and urban planning. Government entities and private companies can monitor the evolution of infrastructure and properties, improving the quality of services offered to citizens, paving the way for the smart cities of the future.

Practical applications

The combined use of BIM and GIS finds application in various fields, including urban planning, natural resource management, infrastructure design, emergency response, and risk management related to calamitous events. For example, in urban planning, integration allows for consideration of not only architectural aspects but also environmental and social aspects, improving the quality of life in cities.

To do this, it is essential to use applications for managing geospatial digital twins that allow for the management of complex and large-scale BIM models and GIS maps complete with geospatial data in a single environment.

The dynamic connection between BIM and GIS represents a significant step towards smarter and more sustainable infrastructure management. Watch the following video. It can provide further insights on how this revolutionary technology is transforming the AEC sector.

You can see how easy it is to insert BIM models on a GIS map, modify them by adding new volumes to the federation, and automatically update the model represented on the map.
