ArcelorMittal’s BIM objects can be rendered to show different levels of detail from the entire facade (first picture below) to the product’s texture (second picture below). These examples show Granite® Impression Agate from ArcelorMittal Europe – Flat Products.
Building information modelling (BIM)
Building information modelling (BIM) digitally integrates the aesthetic design and technical details of a construction project into one information package. BIM gives a digital prototype of the building to everyone involved in the construction, before it is built. ArcelorMittal Europe – Flat Products is the first steelmaker in the world to provide BIM details for its extensive portfolio of aesthetic construction products.
BIMs follow the same model used to design aircrafts and ships, where all relevant information is integrated into a single tool. Building owners, government agencies, engineers, and end users can all see how the construction will look and be utilised. Design changes can be incorporated at a very early stage of the project, which reduces cost and the chance of delays.
The use of BIM has been growing rapidly since it was first adopted in North America just over ten years ago. Today, around one-third of all professionals involved in the construction sector (such as architects, engineers, and contractors) are using BIM. In the United States, BIM is being used by over half of all building contractors
Every construction material used in the completion of the building is described as a BIM ‘object’. ArcelorMittal Europe is currently developing BIM objects for every one of its steel products used in construction.
As the information is virtual, changes to one component of the building are automatically reflected across the BIM. For example, if the size of the doors is changed, the BIM updates accordingly to show the new aesthetics and performance. Safety is also enhanced as materials can be checked to ensure they meet relevant fire or security standards.
Each object typically contains:
- Technical data about the material and a set of design-software files.
- 3D data (indicating texture) so that every steel product for construction can be modelled in virtual reality software.
- Product application details, such as a case study.
Technical data might include weight per square metre or the solar effect of the aesthetics. Details such as steel grade, dimensions, corrosion resistance, and reaction to fire are also included. BIM objects will place full building solutions at the disposal of engineers and architects.
