OpenBIM-GIS applications for Infrastructure

Spatial data management and integration with openBIM technology enable infrastructure challenges to be tackled with greater precision and optimisation. We explore the main applications of GIS in infrastructure.

Infrastructure planning and design

Through geospatial digital twins, sites for new infrastructure development can be accurately assessed. The technology allows numerous layers of data to be overlaid, such as land use, topography, the existing network of roads and services, and environmental information. This makes it possible to identify the most suitable sites for new projects, minimising environmental impacts and optimising costs.

Spatial analysis is a key feature of GIS that enables the evaluation of critical factors such as terrain gradient, accessibility and environmental impact. This information is crucial to ensure that projects are sustainable and aligned with strategic objectives.

Real-time monitoring

OpenBIM-GIS models can also be used during the operational phase of an infrastructure project to monitor the performance and condition of infrastructure. Real-time monitoring is made possible through the integration of GIS with sensors and other IoT devices. Collected information, such as material wear and tear or traffic congestion, is immediately visualised on interactive maps, enabling quick and efficient decisions.

For example, in transport infrastructure, GIS is used to monitor traffic in real time, enabling managers to optimise routes and reduce road congestion. The same principle can be applied for monitoring water, electricity and telecommunications networks.

GIS and Infrastructure Management

The use of GIS in infrastructure management enables the integration of spatial data with information on physical assets, providing a holistic and accurate view of the resources distributed across the territory.

Geospatial digital twins play a key role in infrastructure asset management, improving preventive and predictive maintenance. By integrating spatial data with asset information, the condition and lifetime of infrastructure can be monitored, facilitating maintenance planning.

Sustainability and reducing environmental impact

GIS is a key tool for promoting sustainability, offering advanced functionalities to assess the environmental impact of infrastructure. The integration of GIS and openBIM makes this process even more detailed and precise.

Starting from the spatial view of the GIS, it is possible to display all infrastructures and buildings in the selected area and to switch from the broad spatial context to the openBIM model of a specific building. Using the "GIS Layer" filter, one can select which BIM data to display integrated with the GIS, creating a complete picture that combines the geospatial view with the technical details of the buildings.

In the example below, by selecting a certain area and its 'Spaces' in the GIS, it is possible:

• display the uses of the buildings in the selected area;
• consult the energy class of structures, a crucial aspect in assessing energy efficiency and sustainability.
• access documentation associated with the BIM model, such as an Energy Performance Certificate (APE), which provides key information on the environmental impact of buildings and measures to improve it.

Stakeholder collaboration

usBIM.geotwin allows data and interactive visualisations to be shared on a single platform so that all parties involved in a project can access the same information in real time, improving communication and reducing the risk of misunderstandings. This is particularly useful in complex projects where multidisciplinary teams have to work together.

Geospatial digital twins of buildings or infrastructure can be navigated in multi-user mode, allowing multiple users, located in different locations, to access and interact with the model simultaneously. Each user has the option of navigating the model independently or sharing their visualisation with others, improving the efficiency of collaboration.

Furthermore, through the IFC Editor functionality, any user can make changes to the BIM model, which become immediately visible to all professionals involved in the project. This dynamic update capability ensures that any changes made to the openBIM models are automatically reflected in the GIS as well, maintaining data consistency across both platforms.
