Building Information Modeling

Improve your planning, construction and operations with Building Information Modeling

Building projects, whether in the building construction sector or in the infrastructure sector, are becoming more and more complex. There are lots of reasons for this, one of which is the growing number of people involved in individual projects. And there has also recently been a significant increase in design variety as well as in safety and sustainability requirements. So it is becoming more and more difficult to manage projects like this while ensuring that you adhere to deadlines and keep costs and quality standards within the boundaries you have been set.

Help is at hand in the form of Building Information Modeling (BIM) – which is currently revolutionizing planning and construction processes. It is all about bundling planning data together in one system, allowing buildings to be completed on a virtual basis before progressing to physical construction in concrete, steel and glass.

What lies behind BIM?

BIM describes a digital planning process linking all planners together in a single network. BIM planning uses a database to connect information such as space plans, dimensions, quantities and item descriptions, in addition to costs.

At the same time, BIM is also a new form of interdisciplinary team work (collaboration). It is based on virtual simulation of the building or infrastructure under construction. The BIM process seeks to arrive at a precise performance prediction enabling the economic and environmental effects of the project to be assessed and optimized.

The BIM value chain ranges from basic evaluation through preliminary planning, design planning, analysis, documentation, the production process (including quantity take-off and schedule planning) to site management and facility management. And the data can even be used at a later stage, when it comes to demolishing or renovating the building, for example.

BIM is being used for more and more activities and applications.

It is impossible these days for players in, or observers of, the construction and real estate sector to ignore BIM as a fundamental planning and construction tool. Numerous interest groups, working groups, local BIM clusters, the private sector, public sector authorities and other stakeholders have been dealing with Building Information Modeling for quite some time now.

And, in global terms, BIM has been up and running for many years. The method has gained ground in the United States and the United Kingdom in particular - with corresponding success for principals and other project participants. But BIM is also winning over more and more followers here in Germany, and we now have the first BIM specialist spin-offs for road construction as well as for city and neighborhood projects.

What does the future hold for BIM? Have a peek inside a model!

Using iPads and augmented reality software, you can go inside a virtual reality high-rise building and see how individual disciplines are linked to one another. You can have a peek inside the model courtesy of Drees & Sommer’s app for iPhone and iPad – which you can download free from the App-Store. You will also need to print out the following example.

The market demands standards - and Building Information Modeling is no different in that respect. That is why we at Drees & Sommer have been working with our cooperation partners to get the BIM Blog platform up and running.

If you are interested in finding out more, check out the website and download the BIM Practice Guide 1.0 for free. It provides planers with a content manual for their BIM projects, including field-tested technical and functional specifications. The BIM Blog also contains references, research results, a forum and background information.


In the context of BIM, Drees & Sommer also published the digitization barometer in conjunction with Lucerne University of Applied Sciences and Art.
