Planning and Design with integrated BIM-GIS approach

Explore the benefits of the integrated BIM-GIS approach in the planning and design phases of construction or infrastructure


We are well aware of how crucial the planning and design phases are in the life cycle of any built asset. During these moments, the integration of two technologies like Building Information Modeling (BIM) and Geographic Information System (GIS) can be decisive, offering a series of significant advantages. For instance, BIM-GIS integration allows a more precise site assessment, considering geographic data such as topography, water networks, and environmental conditions, enabling optimal site selection and more efficient design. In this article, we’ll explore the tangible benefits for the AEC sector when realizing synergy between BIM and GIS and managing the integration between BIM models and thematic GIS maps using a BIM-GIS software.

Optimized site selection using GIS Data in BIM project

In the planning phase, choosing the right site is a fundamental step for the success of any construction project. BIM-GIS integration allows a much more precise and comprehensive site assessment. Geographical data, such as terrain conditions, topography, and accessibility, can easily be incorporated into BIM models. Professionals can explore different scenarios rapidly and efficiently, evaluating the impact of variables involved in planning and project design. This assists in selecting the optimal site, considering both problems and opportunities offered by the geographical location.

Efficient urban planning and design with BIM-GIS integration

During the design phase, the integrated BIM-GIS approach offers deep integration between spatial information and project details. This means professionals can work with geospatial data in real-time while designing buildings or infrastructure. Here are some key applications:

  1. Precise Environmental Analysis: Integration with geographic data allows precise evaluation of the surrounding environment, including aspects like sun exposure, prevailing winds, and vegetation. This information is crucial for designing environmentally sustainable buildings.
  2. Water Resource Management: GIS data can provide detailed information on water resource availability and water management. This is crucial for designing effective drainage systems and flood prevention.
  3. Transport and Accessibility Analysis: Access to transport infrastructure is a critical factor in urban planning. BIM-GIS integration allows assessment of accessibility and traffic impact, contributing to planning more efficient roads, parking, and public transport systems.
  4. Environmental Impact Analysis: During design, it’s essential to consider the project’s environmental impact. Using GIS data helps evaluate how the project might affect surrounding fauna, flora, and ecosystems, aiding in informed decisions for environmental conservation.
  5. Resource Management: Planning sustainable projects requires accurate resource management. BIM-GIS integration facilitates the planning and efficient utilization of resources like energy and construction materials.

Enhanced communication and collaboration with geospatial BIM-GIS Digital Twin

Another crucial aspect of this integration is facilitating communication and collaboration among various project stakeholders. All team members, including architects, engineers, urban planners, and local authorities, can work on a single platform with access to updated and shared information.

A geospatial digital twin, resulting from the integration between GIS (Geographic Information System) and BIM (Building Information Modeling), represents a detailed and dynamic digital map of a real environment. This technological fusion allows modeling not only the geography of a place but also the buildings and infrastructure within it.

Imagine constructing a new neighborhood in a city: GIS provides territory mapping, including details like elevation, vegetation, and existing road networks. BIM comes into play to model the neighborhood’s buildings, incorporating aspects like architectural design, hydraulic and electrical networks, and building interiors.

When GIS and BIM integrate, a geospatial digital twin is born: a comprehensive digital representation that combines geographical context with structural and functional details of buildings. This model offers an overarching view that facilitates planning, management, and optimization of urban spaces.

For instance, in urban renewal projects or detailed urban planning, a geospatial digital twin can demonstrate how new buildings will influence traffic flow, street lighting, or water supply networks. Using this technology allows simulating different scenarios before undertaking actual interventions, enabling more informed and sustainable decisions.

Once created, the geospatial digital twin becomes a dynamic resource: sharing real-time information, allowing anyone to access and understand it. This model supports collaboration among different users, such as urban planners, engineers, and residents, facilitating communication and collaboration.

Furthermore, the geospatial digital twin can be easily shared and accessed on various devices, like smartphones or tablets, through web maps, storytelling applications, or sharing platforms. This makes information accessible to a wide audience, enabling employees, clients, and executives to have the necessary information to make informed decisions, anytime and anywhere.

Therefore, BIM-GIS integration offers a comprehensive and synergistic approach to the planning and design of building and infrastructure projects. This integration allows precise site assessment, efficient design, and improved communication among involved parties, contributing to reducing errors, optimizing resources, and ensuring the realization of successful and sustainable projects.
