What is BIM?

Building information modeling (BIM) is the equivalent of digitalization in the construction industry: It is a digitally supported process for planning, constructing and operating buildings that enables a significant productivity increase in the construction industry.

BIM is the answer to today’s building challenges

Construction projects are faced with numerous challenges and obstacles, such as accidents on construction sites, unreliable schedules and costs, insufficient quality and planning errors or inaccurate, incomplete plans as well as a lack of cooperation. But the future of the construction industry is digital – and built upon a holistic approach that connects all parties involved. The result: clear structures, efficient processes, lower costs, less time and higher quality across the entire building lifecycle.

Increase your efficiency and quality with our digitalization expertise

At Siemens, we have extensive experience with the digital transformation process: We virtually invented, accompanied and promoted the digitalization of various industries. We know that it is important to optimize processes, data and tools in order to improve quality, save time and lower the costs of projects – and we know how to do this.

Siemens is a competent partner in all phases of the building lifecycle

In addition to our digitalization expertise, we have a unique overall perspective which is the ideal match for a holistic BIM approach. Our products, solutions and services reflect the entire building lifecycle, all disciplines in the building, the various user and customer types, the different forms of energy as well as the hardware and software products used.

How does BIM work?


Building information modeling is not a software or a synonym for 3D CAD; BIM is the equivalent of digitalization in the construction industry

The BIM process is built on four principles:

Build twice: Building twice is actually more efficient: first the digital model, then the actual construction process. This leads to better collaboration, earlier error and clash detection and a faster overall construction process with fewer errors.

Build and plan together: All stakeholders are involved in the planning process so changes can be made in the model, and cost- and time-intensive modifications on the construction site can be avoided.

Create data only once: It is much more efficient to invest more time in a highly accurate plan than to send someone into the building with a folding yardstick to re-measure.

For the entire lifecycle: Today, the focus of BIM is merely on planning. But BIM has benefits for the entire lifecycle. The data model facilitates service, maintenance and disposal.
