The 2000s are the years when the concept of BIM (Building Information Modeling) was born. The concept of BIM was first mentioned by Autodesk in 2002.

Building Information Modeling (BIM) is a digital representation of the physical and functional properties of a facility. BIM aims to use graphical and non-graphical qualitative data together. Qualitative data; data such as the name of the material, permeability coefficient, technical definitions.

When the developments in technology were able to provide an integrated project environment and a unified working platform in 3D programs, it became necessary to establish interdisciplinary data exchange standards.

In Canada, the Standards and Technologies Institute (Building Smart) (http://www.buildingsmart-tech.org/) introduced the IFC (Industry Foundation Classes) standard, which is the interdisciplinary data exchange standard for BIM solutions. Today, thanks to this standard, the engineering disciplines, which are the stakeholders of the project, have become able to work together on a common platform.

This standard has freed project disciplines from being brand dependent. Stakeholder engineering disciplines do not have to work on the same brand of program. If the architect prefers to work with Allplan, static projects are solved with Tekla, if the mechanical office prefers Revit MEP, if the electrical group uses a different BIM solution, we can combine and display all this data on a common model with this data exchange standard, IFC.

The main data they should use in common is usually the 3D model of the structural skeleton of the project.

In the project solutions of the mechanical and electrical disciplines, primarily the functional and volumetric values of the architectural spaces, the qualities of some objects and the 3D model of the structural elements of the building are needed. At every stage of the project, all disciplines can test conflict control in their own solution packages or in CLOUD sharing environments, thanks to this data exchange in IFC format, and they can make revisions much more easily according to this latest situation.

The most basic function of BIM is seen as providing a unified working platform between all engineering disciplines, which are the project stakeholders. Considering that it may be necessary to work with more than twenty experts in large projects, the importance of this is better understood.

After the adoption of BIM-based studies, Building information modeling has started to be seen as a cultural change in the construction industry all over the world.

Today, these standards have become mandatory with BIM-containing regulations issued in many countries such as the USA, Norway, Finland, Denmark, Singapore, Korea, England.

On January 15, 2014, the European Union Public Procurement Directive recommends making the use of BIM mandatory in public-owned building projects by 2016.
