BIM: what it is, what it is for and why use it
Building Information Modeling – translated into the acronym BIM – is the collaborative architectural design tool that in recent years has changed the way of designing a work. Its conceptual approach is having a strong impact on project development processes, so much so that it is estimated that by 2027 the global value of the software market will reach 15 billion dollars.
NOT A SIMPLE SOFTWARE: THIS IS WHAT BIM IS
Building Information Modeling (BIM) is a methodology that allows architecture, engineering and construction (AEC) professionals to generate a digital model containing information on the entire active project life cycle: from concept to construction until its demolition and disposal.
With BIM, rather than a three-dimensional representation, it is possible to create a dynamic, interdisciplinary and shared information prototype, i.e. a digital twin of the work that contains data on geometry, materials, load-bearing structure, thermal characteristics and energy performance, systems, costs, safety, maintenance.
These are, therefore, virtual models that improve and expand data management and allow designers to work according to a collaborative approach, sharing technical choices, detecting and resolving any inconsistencies and errors.
ALL THE ADVANTAGES OF DESIGNING WITH BIM
BIM is therefore a design method born from the need and desire to involve different professionals, as it allows useful information to be integrated into a single model in each phase of the design: from architectural, structural, plant engineering to energy and management.
Furthermore, BIM technology offers multiple advantages such as:
- greater efficiency and productivity
- less downtime
- less costs in the long run
- a more punctual and coherent control of the project.
- But not only that: equally important is the total elimination of errors, duplications and interferences, thanks to the real-time updating of all project tables based on the variations made.
A Building Information Modeling project gives the client the opportunity to have a virtual elaboration of the building's life cycle, even after the design phase. The models created with this methodology can then be used to carry out simulations or precise calculations of materials, freeing the designer from this type of activity and allowing him to concentrate above all on the design.
However, despite the important advantages and the considerable simplification of the work, it must be considered that the use of BIM requires greater investment and work in the initial phase of the project.
HOW PROJECTS ARE SAVED WITH BIM
Generally a BIM object is saved in the IFC (Industry Foundation Class) format, with a .ifc extension. These IFC files are classified as 3D image files, which also contain other technical information, and are compatible with all software that uses BIM technology.
With IFC files you can:
- determine the geometric characteristics of objects;
- establish relationships between components, differentiated based on use;
- filter the data to transport only those truly necessary for the purpose.
WHAT WILL BE AFTER BIM?
While the first prototypes of BIM, dating back to the 1970s, focused on its functions as a computer-aided design (CAD) tool, BIM in the 21st century is much more than drafting software.
In the future, it is poised to continue evolving as a collaboration tool to optimize all phases of a building's lifecycle, aided by increasing interoperability with other automation tools.
