BIM – Building Information Modeling

PIUTEK is able to prepare customized libraries for component and technical closures producers, creating REVIT family files ready to be used in BIM architectural models.
The world of building design is now oriented towards “Building Information Modeling”, in short BIM and according to the “Decreto Baratono” DM n. 560 of 1/12/2017, which entered into force on 27/01/2018, in Italy, all public works up to 1 million euros from 2025 must be designed and managed in BIM.
A fast change is expected in the construction sector, which starting from the world of design, will involve all the important players, including components and finished products producers for the building industry.
What is BIM ?
The NIBS (National Institutes of Building Science) defines BIM as the “digital representation of physical and functional characteristics of an object”.
BIM can be imagined as a process of:
  • programming
  • design
  • realization
  • maintenance
of a building that uses an information model, that is a model that contains all the information concerning its entire life cycle, from the project to the construction, up to its demolition and disposal. With BIM there is the collaboration between the different figures involved in the different phases of the life cycle of a structure, in order to insert, extract, update or modify the information of the architectural project, its components and related contents. For example, the architectural designer defines the shapes, the geometries up to the 3D model; the structural designer defines the elements of the structure (beams, pillars, walls, foundations, etc.), etc.
Thanks to BIM it’s possible recreate a virtual building model that is not a simple three-dimensional representation, but a dynamic model that contains a series of information on:
  • geometry
  • materials
  • load-bearing structure
  • thermal characteristics and energy performance
  • installations
  • costs
  • safety
  • maintenance
  • life cycle
  • demolition
  • disposal
  • ecc.
According to the above thanks to the BIM methodology, the building is “built” before its physical realization, through a virtual model and the collaboration and contributions of all the actors involved in the project (architects, engineers, consultant designers, energy analysts, etc.). The main feature of this philosophy is a highly strategic approach, which offers the opportunity to analyze the architectural object and evaluate its performance already in the design phase.
What kind of advantages does BIM offer ?
The BIM use allows significant advantages which take shape into:
  • time and cost savings: the designer will no longer have to draw a copious amount of lines, polylines and various geometric shapes (which take a lot of time), but will simply have to insert objects with specific properties and information of various kinds (materials, costs, thermal capacity, maintenance, etc.)
  • error reduction: plans, elevations and sections are simply different views of the same object. Any modification to the BIM model affects all the generated views / diagrams
  • greater simplicity: it’s easy to generate even very complex models. The technician will be able to design works that he wouldn’t even previously imagined using a CAD.

WHAT IS NEEDED ?

In order to be present in the BIM world, components and technical closures producers for the building industry should make available parametric and customized libraries of their productions, “parametric families” such that they can be incorporated into the architectural project. These libraries must contain all the qualitative information, techniques, performance, the dimensional limits and the information necessary for installation, use, maintenance and disposal.
It is very important to have information about the characteristics and performance of the product:

  • mechanical and electrical safety according to the reference standards;
  • wind resistance class;
  • air permeability class;
  • water permeability class;
  • global thermal transmittance;
  • noise reduction;
  • durability of performance (cycles);
  • mechanical durability (cycles);
  • cycle time;
  • number of cycles / hour;
  • environmental compatibility;
  • flame classification;
  • smoke resistance class;
  • fire resistance class;
  • corrosion resistance;
  • UV resistance;
  • energy efficiency class.
It is also necessary to have appropriate manuals, already needed according to the CE marking, which allows the access to information for the correct use and ordinary and extraordinary maintenance.
Finally, it’s necessary to have a website with appropriate specific in-depth content.
