Benefits of BIM and GIS integration in construction

The integration between BIM (Building Information Modelling) and GIS (Geographic Information System) represents a great evolutionary leap in the construction sector, especially for the design and management of large infrastructure works. In fact, by combining the power of location intelligence with BIM processes, it is possible to obtain a more complete and useful vision for the management of both public and private works.

Let’s discover together what are the advantages for the construction sector and how to manage the integration between BIM models and GIS thematic maps thanks to a BIM-GIS software.

BIM GIS integration

What is BIM GIS integration?

The integration between the BIM (known as the process of managing the digital container of information relating to a work) and the GIS (geographical information system that allows to represent the events that occur in a given territory) is the process that generates a workflow capable of exchanging data from one system to another without loss of information, interrogating the data within a single database.

An approach based on the centrality of the data generates a more in-depth vision of the work and the urban and natural context of reference. This results is an informed decision-making process, greater involvement of stakeholders and faster and more effective processes.

Thanks to this new type of approach, GIS data enriches the BIM model with information and BIM in turn feeds data from GIS information systems.

The criterion of the digital twin applied systemically also for infrastructures allows to collect in a single container the geometric model of the work, the technical sheets but also the GIS data relating to the territory in which the infrastructure is located (weather information, seismic data, etc.).

There are many fields of application: the information in GIS maps can be exploited in a BIM process to improve environmental resource optimization, energy saving, security and much more.

Here is a concrete example.

By leveraging data entered in GIS thematic maps, such as building sizes, paved areas, permeable areas, etc., it is possible to identify the amount of rainwater that can be collected and consequently, design adequate and well-sized collection systems to irrigate public green, parks and gardens.

How to integrate BIM and GIS with usBIM

Or again, in the case of designing large-scale infrastructure works, such as a road system that also includes specific works such as bridges, service stations, etc., we would start from the BIM model of the road system and the various specific works, up to a complete cartographic database, thanks to integration with GIS data and maps.

All this information flows into a single digital container accessible by all, safe and always available and implementable over time.

One could even imagine creating a cadastre of public works, uploading this information all together and linking it to the National Information Archive of Public Works. This mechanism would also make it possible to monitor the state of management and conservation of the works themselves.

In summary, the parties involved in the analysis, planning and design phases will be able to better understand the projects in their context and predict the impact they will have on the natural and built environment.

The acquisition of these details in the initial phase of the life cycle of a project will also make it possible to foresee any problems and reduce risks and delays in deliveries.

BIM and GIS integration for infrastuctures

What is the difference between BIM and GIS?

BIM and GIS are two methodologies that work very well together.

Today, in fact, more than talking about the difference between the two (BIM vs GIS), we tend more and more often to see them in terms of integration.

However, in some cases there is still someone who puts the two technologies in competition with each other rather than in coordination. According to this current of thought, the BIM must deal with the management of data relating to the building and the GIS of everything that surrounds the building itself but without a mutual interaction between the two disciplines.

In fact, it is believed that CAD integrates better with the GIS system and is more flexible to analyse and graph data referring to the urban scale.

This belief also stems from a not yet in-depth knowledge of BIM and the tools currently available.

It is only a matter of time, therefore, and the integration between BIM and GIS will lead to a change that is proving beneficial for everyone.

Online software to manage the integration between BIM and GIS models

To achieve this, we need a single system, a BIM-GIS software, that integrates GIS data and BIM models.

usBIM.gis is the GIS cloud service that allows you to:

• import, view, and edit GIS maps in .GeoJSON made with other applications
• create new GIS maps linked to BIM models starting with OpenStreetMap™, Esri.WorldImagery™, GMaps-Streets™, GMaps-Satellite™, GMaps-Terrain™
• insert graphic elements and notations such as lines, rectangles, polygons, markers, layers, and custom properties
• integrate BIM models and Google Maps
• connect documentary links from the cloud platform to create real thematic maps of the BIM model
• collaborate with multiple people and in real time on the same document
• export documents in GeoJSON format.

Basically, you have an integrated system that is configured as a cloud environment in which BIM professionals and GIS designers can collaborate throughout the life cycle of a work, integrating and updating GIS and BIM data over time.

Stakeholders can take advantage of digital information stored in the cloud, update data based on analyses conducted over time and make more informed decisions, also monitoring the impact of the work on the reference context.

Creating GIS maps with usBIM.gis

By selecting an object from the map (imported externally or made from scratch directly on usBIM.gis), you can view its properties and manage them thanks to numerous editing features.

The integration between BIM model and GIS map can be completed by adding information to the map by associating links to documents already uploaded to the platform. usBIM is in fact also a solution for BIM document management with which to manage all documents in the BIM process.

How to operate with usBIM.gis

The interface of usBIM.gis is extremely simple and intuitive:

• on the left side of the screen there are folders for storing markers and polygons and dividing them into layers;
• at the centre is the map (satellite or vector);
• on the right side there is one of the three menus showing:
  • users and messages (it is possible that several users are connected at the same time on the same file and there is the possibility to communicate in the integrated chat);
  • properties of the selected objects;
  • attached documents.

usBIM.gis also allows you to attach documents from your device or from an online folder on usBIM cloud.

The advantages of BIM GIS integration for the infrastructure sector

The integration of Building Information Modeling (BIM) and Geographic Information Systems (GIS) represents a significant step toward the digital transformation of the built environment. By combining detailed building information with geospatial context, BIM–GIS integration enables the simultaneous management of infrastructure models and their territorial reference systems. This approach allows field data to be efficiently acquired, visualized, and analyzed within a geospatial framework while preserving the rich semantic information embedded in BIM models.

Beyond the scale of individual assets, BIM–GIS integration supports a broader understanding of urban and territorial systems. This capability makes it a valuable tool for urban planning, infrastructure management, environmental analysis, and regional development, enabling stakeholders to assess projects within their wider spatial and socio-economic context.

Ultimately, this integration promotes the creation of more sustainable projects and allows for:

• more informed and efficient decision-making;
• reduction of construction and management costs;
• interoperability and collaboration among all parties involved (technicians, clients, public administrations, etc.);
• the development of “smart” cities;
• reduction of construction times.

Through recent and ongoing developments in new technologies, IoT, cloud computing, AI and machine learning, a tool that has been used for several years by leading companies in industrial production and technology has been extended to the urban context: the ‘digital twin,’ a virtual representation of a physical entity, which communicates in real-time through two-dimensional interactions, forming a holistic system in which the physical and virtual aspects mutually promote and evolve each other.

An essential tool for creating an urban ‘digital twin’ is certainly the integrated use of BIM and GIS methods.

These two systems originate and develop from different premises and therefore their interoperability, or the fluid and joint use of the two systems, is not optimal. It is therefore of common interest to fill these gaps for the realization of a tool deemed fundamental for the creation of an urban ‘digital twin’ and thus a ‘smart city.’

Thanks to the openBIM GIS technology and the dynamic connection between the usBIM platform from ACCA software and Esri Italia’s ArcGIS technology, openBIM and GIS are finally integrated to create Geospatial Digital Twins and Smart City.

BIM-GIS integration for territorial management: the BimToCim project

The BimToCim project aims to overcome the limits of traditional urban management by reading the information of BIM models on a territorial scale through GIS systems.

This has been made possible through the collaboration of various entities:

Leading Entities and Project Partners

• ACCA software
  University of Federico II in Naples

Consultants and Research Participants

• National Research Council (CNR), with the specific contribution from the Department of Earth System Science and Technologies for the Environment and the Institute of Methodologies for Environmental Analysis
• Politecnico di Milano
• Politecnico di Torino
• IUAV of Venice

Funding and Institutional Entities:

• Campania Region, which financed the initiative through the Campania FESR POR 2014/2020
• The Department of Civil Protection and ISPRA, which provide essential data related to hydraulic, seismic, and landslide hazards on a national scale

Stakeholders and Recipients of the system:

• The Public Administration, which can use these tools to have a precise overview of the condition of buildings in the territory
• Citizens, property owners, and real estate managers, beneficiaries of an updated tool on the actual conditions of safety and maintenance of real estate units

This synergy allows for the transformation of punctual data from a single building into a strategic resource for planning and urban safety, facilitating the transition from an architectural detail scale to a territorial type scale.

The digital “Building File”: the identity card of the building

The informational core of the system is the building file, understood as a true digital identity card of the building. Unlike traditional methods based on fragmented paper archives, the digitized process centralizes data related to safety, stability, systems, and maintenance in a single data sharing environment (CDE).

Thanks to the Open BIM approach, the 3D model is no longer just a geometric object but becomes the container of the technical documentation itself, where every piece of information is geo-referenced and directly associated with the physical elements of the construction.

From Digital Twin to real-time monitoring via IoT

The innovation of the project lies in the creation of a dynamic Digital Twin, capable of evolving over time through the connection with IoT sensors. These devices, installed on the building, send real-time data on structural, energy, and safety parameters directly to the BIM model in IFC format.

This integration allows for constant remote monitoring: the model visually reacts to events (such as the opening of a window or the detection of an anomaly), transforming into an active monitoring tool essential for managing the project’s life cycle.

The CIM Geoportal and risk analysis in the Potenza use case

Through the CIM geoportal (City Information Modeling), the information from BIM models is projected onto the territory and cross-referenced with external cartographic layers, such as maps of seismic, hydraulic, and landslide hazards provided by ISPRA and the Civil Protection.

A concrete example of this application was conducted in the municipality of Potenza, in the area of the Basento River. Here, the system allows filtering buildings based on construction type (e.g., masonry or wood) or the presence of structural damage, immediately visualizing which properties fall within areas at high hydrogeological risk. This aggregated view provides fundamental support for estimating territorial safety and predicting the behavior of buildings in the presence of exceptional events.

FAQ on BIM – GIS integration

What is BIM GIS integration?

The integration between BIM (understood as the process of managing the digital container of information related to a work) and GIS (geographic information system that allows representing events occurring in a given territory) is the process that generates a workflow capable of exchanging data from one system to another without loss of information, querying data within a single database. This approach is based on the centrality of the data and generates a more in-depth view of the work and the urban and natural context, allowing for informed decision-making, greater stakeholder engagement, and faster and more effective processes. Thanks to this approach, GIS data enrich the BIM model with information, and BIM in turn feeds the data of GIS information systems, systematically applying the digital twin criterion even for infrastructure.

What are some concrete examples of BIM and GIS integration application?

By leveraging data entered into thematic GIS maps (such as building footprints, paved areas, or permeable areas), it is possible to identify the amount of rainwater that can be collected to design adequate collection systems for watering public green areas. Furthermore, in the design of large infrastructure works such as a road system that includes point works (bridges, service stations, etc.), one can start from the BIM model of the road system and the various works to arrive at a complete cartographic database through integration with GIS data and maps. All these pieces of information converge into a single digital container useful for creating a registry of public works linked to the National Informative Archive of Public Works, allowing monitoring of the state of management and conservation of works.

What is the difference between BIM and GIS?

Currently, there is a tendency to view the two methodologies in terms of integration rather than difference (‘BIM vs GIS’). Although in some cases there are still those who see the two technologies as competitors, believing that BIM should only deal with building-related data while GIS covers everything surrounding the building without any mutual interaction (arguing that CAD integrates better into GIS for analyzing the urban scale), this belief stems from a yet shallow understanding of BIM. The integration of BIM and GIS will lead to a beneficial change for all, allowing for better understanding of projects in their context, predicting impact on the natural environment and the built environment, and reducing risks and delays in deliveries from the early stages.
