WHAT IS BIM? BRIEF SUMMARY
Building Information Modeling, or BIM for short, is a technique that enables networked planning, execution, and management of buildings. This creates a digital representation, that is, a three-dimensional model that contains information about the physical and functional characteristics of the building. Information is collected centrally in one place and therefore is available to all participants. The building data model, with all its information, is a reliable basis for decision making throughout the entire life cycle of a building, from idea to demolition.
There are many benefits to using this method of work for all stakeholders from various fields such as construction and real estate or property management. One of the advantages of the BIM method is, above all, the centralized data management, since all information can be called up from one place. So a structured and efficient work is possible. We have collected additional information on the BIM topic for you on our BIM page.
THE RISE OF INFORMATION MODELING OF BUILDINGS
The history of BIM goes deeper than some people think. The origins of Building Information Modeling are not a fixed date or 100% clear. However, there is no doubt that it was a gradual process and constant development. Despite many years of development and knowledge, BIM has not yet become ubiquitous. Our brief history brief gives you an overview of what happened, what made us use BIM today. BIM originally came from the automotive industry. In this article, however, we are only looking at the construction industry.
First BIM approaches
To understand the history of BIM, we must go back to the late 50s. In 1957, the company Pronto was founded by an American Dr . Patrick J. Henratty developed. It was the first commercial computer-aided manufacturing (CAM) software. Some time later, Hanratty took up computer graphics, as a result of which DAC ( Design Automated by Computer ) appeared in 1961 . It was the first CAM / CAD system with interactive graphics.
The further development of the systems went on steadily. In 1963, Ivan Sutherland developed the first system of computer-aided design (CAD) software with a graphical user interface called " Sketchpad ". A big breakthrough in the development of computer graphics, and then the method of building information modeling.
Preliminary database model
In the mid-1970s, experienced architect Charles M. Eastman published his work on a prototype called the Building Description System (BDS). It was about the idea of parametric design and high quality computable 3D representations with an integrated database for visual and quantitative analysis. He also criticized the drawings for their tendency to deteriorate over time and for the lack of depiction of the building when renovations are underway and the drawings are not updated. Then came the term “automatic model verification” for “design validation”. Basically, this work was about BIM as we know it today. He developed a program that gave each user access to a sorted database. The database also used graphical user interfaces with orthogonal and perspective views. BDS was one of the first projects to successfully create a building database.
The development of revit outsourcing as we know it today
In the 1980s, more and more systems were developed, some of which were also used in construction projects. During the Cold War, computer genius Gabor Boyar smuggled Apple computers into Hungary for software development. In 1982 he started developing ArchiCAD . ArchiCAD later became the first BIM-enabled software available on the PC. Today there are many different BIM service providers such as karnoenergy.com and others. They provide their services to a mass of users around the world and experts predict that bim companies will become one of the most promising and profitable in the construction industry in the future.
