— BIM: Building Information Modeling – Definition, Methods and Applications

How Does BIM Work?

Data on every component of a building — including the various planning aspects — is stored centrally, so that all stakeholders can access and use it to work more effectively. This reduces the risk of errors and discrepancies, saving significant costs.

The data that feeds into the model defines the design elements, their behavior, and the relationships between model components. When one element of the model is changed, the section view, elevation, and floor plan are all updated automatically to reflect the new version.

In addition, BIM data can map the entire lifecycle of a building — from planning and foundations through to demolition and material reuse. Spaces, systems, products, and workflows can be represented in relative scale to one another. Thanks to clash detection, errors in the various development and construction phases can be identified and avoided early.

Cloud technologies can make BIM even more powerful. Companies want to win more contracts, deliver projects more efficiently, and design better buildings — BIM provides the digital foundation for exactly that.

What Are BIM Models?

A BIM model is a digital, three-dimensional representation of a building or structure that goes far beyond a simple 3D visualization. It contains all relevant information about a structure: geometry, materials, costs, schedules, technical properties, and operational data — all centrally linked and updated in real time.

BIM models differ depending on the planning phase and the level of detail. The Level of Detail (LOD) describes how precise and information-rich the model is — from a rough conceptual representation to a fully developed as-built model that documents the actual built state.

Unlike traditional CAD drawings, BIM models are intelligent: every component knows its properties and its relationships to other elements. When a component changes, all connected views, plans, and calculations adjust automatically.

What to Consider in BIM Planning

BIM planning is more than just the use of a specific software — it requires a clear strategy, defined processes, and the willingness of all project participants to collaborate.

Define BIM Goals Early

Before a project begins, it should be determined which goals are to be achieved with BIM — cost certainty, clash detection, facility management, or all of them combined. This influences the required level of detail and the tools to be used.

Clarify Roles and Responsibilities

A BIM project has clear roles: the BIM manager, BIM coordinators, and the respective specialist planners. Without clear responsibilities, gaps and errors emerge in the model.

Use Open Standards

To ensure compatibility between different software systems, it is advisable to use open standards such as IFC (Industry Foundation Classes). This prevents data loss when exchanging information between different trades.

Ensure Consistent Data Maintenance

A BIM model is only as good as the data maintained within it. Regular updates, clear naming conventions, and a consistent model structure are critical to the quality of the overall model.

How Does e-shelter security Use BIM?

At e-shelter security, we use BIM to create a digital twin — consisting of floor plans, infrastructure elements, and additional building data — of our customers’ sites and buildings. We define areas such as rooms or hallways and add the corresponding resources: desks, sensors, actuators.

Through BIM, we can offer a range of capabilities:

• Indoor localization with all associated use cases such as navigation and searching for employees and resources
• Availability of free desks and rooms for online booking
• Quantitative analysis of occupancy and resource utilization
• Control of the automation system (lighting, heating, ventilation)
• Access control
• Building management and cleaning workflows

Conclusion: BIM as the Foundation for the Building of the Future

BIM has clear benefits and has become indispensable in modern construction and building planning. Especially for highly complex building types such as data centers, individual BIM dimensions are becoming essential: 3D ensures a clean model in the face of extreme complexity and density, 6D addresses critical energy efficiency, and 7D makes maintenance and availability predictable. In addition, 4D provides transparency in complex construction and fit-out phases, and 5D delivers control over a sensitive cost structure.

Inefficiencies and waste in construction can be specifically reduced with BIM. When all stakeholders collaborate in a shared BIM environment, many of these problems are eliminated — laying the foundation for a better, more sustainable future of building.
