BIM and GIS

BIM-GIS Integration: How to Obtain a Holistic View of Projects Throughout the Life Cycle of a Project

BIM-GIS integration represents a crucial step in the field of civil engineering and construction. This synergy between two powerful systems offers a holistic and detailed view of projects, bringing significant advantages throughout the life cycle of an infrastructure or building. The combination of these two technologies helps to monitor the safety of infrastructural assets, building performance, energy consumption, maintenance scheduling and costs, HVAC equipment operation, and more effectively.

To fully understand this integration, it is important to define what is meant by BIM and GIS.

Building Information Modeling is a methodology that allows for the creation and management of 3D computerized models of a building or infrastructure. These models contain detailed information on every component, from materials used to technical specifications, providing a precise virtual representation of the structure.

GIS, on the other hand, stands for "Geographic Information System." These are powerful tools that allow us to collect, store, analyze, and visualize geographic data efficiently. But why are they important? We live in an increasingly complex world where geography and location are fundamental. GIS enables us to better understand our environment, make informed decisions, and solve real-world problems.

A GIS system locates objects contained in a database in space, and therefore on a map, grouped based on similar characteristics, managing them as georeferenced thematic information layers.

These computer/geographic systems are primarily designed for:

• land management;
• urban and infrastructure planning;
• studying territorial transformations over time;
• Civil Protection plans;
• creating thematic maps (hydrographic, seismic, demographic, traffic, etc.);
• statistics and demography;
• studying archaeological-cultural/environmental/building heritage;
• GPS applications.

These systems allow for detailed and complex planning of the territory and interventions to be carried out on it, house by house, street by street, in an extremely detailed manner.

OpenBIM and GIS: A Step Towards Maximum Interoperability

Maximum interoperability in a BIM process is made possible by openBIM. OpenBIM is a collaborative approach to designing and managing construction information, based on open standards that allow for information sharing across different software platforms. With openBIM, all members of the design and construction team can collaborate effectively, avoiding errors and improving project quality. But why is it essential to implement an openBIM approach even in integration with GIS?

Enlightened contracting authorities and managers require BIM-GIS integration not only with proprietary formats but with open formats. The technologies currently being tested have two fundamental limitations:

• they operate on proprietary formats;
• they copy and replicate data between BIM and GIS systems.

Hence the need for a new system to robustly integrate the two worlds of GIS and openBIM.

And this is why from the synergy of ACCA with Esri®, the main players globally in the openBIM® and GIS field, usBIM.geotwin is born, an absolutely innovative technology to create and manage digital twins of their projects by integrating GIS geospatial data with openBIM IFC models.

No longer a static import of data from one system to another, but a dynamic and bidirectional integration of the two systems. All built assets, buildings, bridges, roads, railways, and all types of infrastructure, can provide detailed real-time data to the GIS system, allowing the territorial system to query the data of each infrastructure and integrate them.

With no limit to complexity, number, and continuous data updates!

BIM GIS Integration

BIM-GIS serving AECO professionals' work

GIS has proven to be essential for AECO industry professionals. Master plans, environmental impact studies, projects and planning, geological, seismic or environmental monitoring mappings, cadastral practices, traffic management, planning interventions for the conservation of vulnerable ecosystems, emergency management such as wildfires or floods: GIS is a powerful tool for territorial governance.

Let's now see how the integration of openBIM and GIS offers numerous advantages in the construction sector, in the different phases of a project's life cycle, improving project quality, resource management, and urban planning.

How BIM and GIS support architecture and civil engineering

The integration of BIM and GIS is crucial to enhance spatial understanding, optimize resource allocation, and promote sustainable design in civil engineering and architecture projects.

The combination of these two sets of data allows design and construction teams to obtain a more complete and accurate understanding of the built environment, enabling them to make more informed decisions throughout the project's life cycle. Architects and engineers can:

• explore spatial relationships, conduct site analyses, and assess the impact of proposed developments, leading to more efficient and effective territorial planning and infrastructure projects;
• identify optimal locations for infrastructure, public services, and structures, streamlining resource utilization and minimizing conflicts;
• analyze environmental factors such as terrain, vegetation, and natural resources to make decisions that minimize the environmental impact of construction projects and promote sustainable design practices;
• optimize data exchange and collaboration among multidisciplinary teams, ensuring that professionals have access to updated and accurate information throughout the project's life cycle.

To discover all the applications and benefits of GIS in civil engineering, read the in-depth analysis on the topic “What is GIS in civil engineering”.

BIM and GIS in the construction phase

Just as in the planning and design phase, the integrated BIM-GIS approach offers numerous practical advantages during the construction phase. In particular, it allows for:

1. contextual visualization:
   the synergistic interaction of geographic data provided by GIS with BIM model information offers a broader and contextual perspective that allows stakeholders to fully understand the context in which the building structure will be placed. Through this integrated approach, it is possible to evaluate the project's environmental impact in relation to surrounding elements, enabling more informed decision-making during the design and construction phase. Furthermore, the combination of geographic data and BIM information helps identify geospatial constraints, whose early identification allows mitigating potential issues during construction;
2. resource management:
   another fundamental aspect of BIM-GIS integration is the optimized resource management during the construction phase. Spatial analysis provided by GIS can be used to optimize resource allocation;
3. risk reduction:
   integrating detailed project data with geographic information helps mitigate construction-related risks. For example, BIM-GIS integration allows simulating construction impacts in advance, reducing the risk of unforeseen events or negative impacts on the surrounding environment. Additionally, sharing and centrally managing information between BIM and GIS reduce communication and interpretation errors, improving data consistency and reducing costs associated with corrections during construction;
4. construction site progress monitoring:
   during construction, it is essential to track the progress of the site to ensure the project stays on schedule. BIM-GIS integration enables the creation of real-time interactive site maps, showing the location of different work teams, equipment, and materials. This allows for dynamic planning and timely resolution of potential issues that may arise;
5. quality control:
   quality control is crucial during construction. Using BIM and GIS data allows for constant comparison of what is being built on-site with project plans, identifying any discrepancies promptly. This ensures that the final result complies with the project's specifications and requirements.

You can fully leverage these and many other advantages through Geospatial Digital Twins, digital replicas where geospatial data is perfectly combined with built information from BIM models and immediately usable in the design, construction, and maintenance activities of a project. The synchronization of geographic data and design information provides a comprehensive and real-time overview of construction operations. A synergistic approach that enables more efficient project and resource management, allowing to achieve performance levels previously unimaginable in the construction sector.

BIM and GIS in asset management and maintenance phase

The management and maintenance phase is crucial to ensure that buildings and infrastructure remain safe, efficient, and functional over time.

In the constant evolution of the construction sector, the synergistic approach between Building Information Modeling (BIM) and Geographic Information System (GIS) is bringing significant improvements even during the Operational and Maintenance (O&M) phase.

All AECO professionals involved in the management and maintenance of a built asset require a large amount of information, very diverse from each other, which must be managed with technology that allows them to compare complex data concerning not only individual buildings or parts of them but also the environment or landscape in which they are located. BIM and GIS represent today some of the most innovative technologies that can be used in this phase.

On one hand, BIM allows for the development of highly detailed building information models; on the other hand, GIS enables their management and analysis through a global spatial reference system. The great potential of their integration lies in the ability to manage the asset from the territorial macro-scale to the micro-scale of the individual building component or system.

BIM and GIS in asset management and maintenance phase

Here are some examples of aspects of the maintenance phase that can benefit greatly from BIM-GIS integration:

1. Facility and Plant Management: One of the main aspects of maintenance is the management of facilities and plants. BIM-GIS integration allows access to detailed BIM models of structures, data on their geographical location, and historical maintenance information. This greatly simplifies the planning and management of preventive and corrective maintenance activities. To learn more, read the article "GIS for Asset Management: the complete guide".
2. Real-time Condition Monitoring: The use of sensors and IoT (Internet of Things) technologies can provide real-time data on asset conditions. This data can be integrated into BIM-GIS systems, allowing constant monitoring of structure performance and conditions. This enables the quick identification of any issues or anomalies, minimizing downtime and repair costs.
3. Resource Optimization: BIM-GIS integration contributes to resource optimization. It is through more precise data-driven management that it becomes possible to plan human and material resources more efficiently, reducing maintenance costs without compromising service quality.
4. Preventive Maintenance Planning: The BIM-GIS approach allows for detailed planning of preventive maintenance. One of the main advantages of the BIM-GIS approach in managing and maintaining built assets is the ability to plan and execute maintenance interventions more efficiently. By using data from both BIM and GIS, predictive maintenance plans can be created based on detailed information about the current state of the building and its surrounding environment. For example, using GIS to analyze the external environment can help predict and better prepare for any natural events that could affect the structures. Meanwhile, BIM provides a detailed internal view of the building or infrastructure components, helping to plan targeted maintenance interventions to extend their lifespan. Additionally, sensors installed in the building can collect real-time data on structural conditions and system performance. This data is integrated into the BIM-GIS model, allowing operators to identify potential problems early and plan preventive maintenance: this reduces downtime, optimizes resources, and extends the building's useful life.
5. Informed Decisions: Access to detailed information on the current asset conditions allows for informed decisions regarding the necessary investments to improve sustainability, energy efficiency, and regulatory compliance.
6. Asset Protection - Risk Management and Real-time Updates: The ability to view data in a geographic context allows for the identification of potential environmental risks, such as floods or climate changes, and assess their impact on the building or infrastructure. When emergencies or critical situations occur, the BIM-GIS approach is crucial for a rapid and effective response. The digital model provides a detailed overview of structures and available resources, enabling response teams to make informed decisions and act promptly. Furthermore, the BIM-GIS model can be updated in real-time during an emergency, recording damages or changes to the structures. This information is valuable for post-emergency assessment and planning of restoration activities.
7. Spatial Navigation and Safety: In the context of complex buildings or extensive infrastructures, such as airports or hospitals, the integrated BIM-GIS approach facilitates spatial navigation. This can be particularly useful for staff, visitors, or emergency responders who need to move within the environments. Additionally, BIM-GIS integration contributes to safety, allowing for more effective management of evacuations in case of emergencies.

Thanks to specific connectors to Facility Management and IoT, usBIM.geotwin presents itself as an innovative and comprehensive solution for the management and maintenance of built assets. These integrate geographic data and detailed information on structure components for smarter planning of maintenance interventions and updates.

Practical Examples of BIM GIS Integration in AECO

To demonstrate the potential of integrating BIM and GIS in improving efficiency, sustainability, and decision-making processes in the AECO sector, here are some practical examples of BIM-GIS integration use in AECO.

BIM GIS and AI

The management and planning of infrastructure and construction are further optimized by combining BIM-GIS integration with Artificial Intelligence (AI). This combination of technologies provides a more comprehensive and useful view for managing both public and private works.

ACCA software, in collaboration with Esri, has developed this innovation and created usBIM.geotwin, which integrates GIS data and openBIM IFC models with AI.
Through this technology, it is possible to:

• interact with the system, requesting detailed information on the models and receiving instant responses;

• obtain detailed graphs for better data understanding;
• ask for the selection of a specific object and receive an accurate description of its characteristics, location, and dimensions.

GIS-AI-openBIM

BIM and GIS in public procurement

The use of digital technologies, such as Building Information Modeling (BIM) and Geographic Information System (GIS), is becoming increasingly common in the context of public procurement.

BIM can be used in all public procurement processes, from design to construction and building management. Through a BIM model of a project, designers can identify any issues or errors already in the design phase, plan the construction of the building more efficiently, monitor the construction progress, and manage maintenance.

The transition to BIM is not quick and must be planned from the beginning.

GIS, on the other hand, allows for more effective visualization and analysis of geographic data. This is particularly important in public procurement, where many infrastructures extend over very large geographic areas. GIS can be used in public procurement for territory analysis, identification of construction sites, and management of environmental risks.

The combined use of the two technologies just described in public procurement offers numerous advantages, including:

1. improvement of project quality:
   BIM and GIS, by enabling greater collaboration and coordination among the professionals involved in the project, improve project quality and help reduce the risk of errors;
2. reduction of construction times:
   the two technologies (BIM and GIS) allow for more efficient planning and management of construction, reducing construction times and improving workplace safety;
3. greater sustainability:
   BIM and GIS help reduce the environmental impact of the building and ensure project sustainability;
4. cost reduction:
   BIM and GIS enable more efficient project management, reducing costs associated with design, construction, and building management.

Implementing BIM and GIS in public procurement can be a challenge due to the quantity and complexity of the data involved and the need to collaborate with many stakeholders.

A challenge that can be easily overcome thanks to collaborative applications and platforms that are easy to learn and use:

• specific applications that, through intelligent integration of BIM and GIS, allow for the digitization and geospatial management of buildings and infrastructures without limits on complexity, number, and continuous data updating;
• BIM data sharing environment certified IFC by buildingSMART international;

BIM GIS and Smart city

Smart Cities are urban spaces that apply Information and Communication Technologies (ICT) and the Internet of Things (IoT) to optimize and improve infrastructure and services to citizens, making them more efficient and sustainable.

For an efficient implementation of a Smart City Project, the development of a digital system capable of managing and visualizing geospatial data in a user-friendly environment is necessary. The solution to this need lies in the implementation of the Geographic Information System (GIS) which offers advanced and user-friendly functionalities for smart city projects.
