BIM stands for Building Information Modeling, is the tool to support communication, cooperation between the parties, simulation and optimal improvement of a project during the design phase and the complete cycle of built work life.


Through targeted framework, it will be clear and simple for every professional team how to deal with the parties involved and how best to use the BIM tools available.
 Design through the BIM systems is considered a revolution that affects the integrated management systems for architectural design.
To understand the benefits you have to consider a few points:



• The use of BIM system reduces construction costs. Over the last 40 years the building systems have not changed and optimizations unlike the buildings that have taken complexity always higher.

• The use of BIM system reduces project management time. The BIM design activity compared to a conventional design is concentrated in the initial phase of the project matured with the closing of the realization of the model. From that moment the automatism of BIM systems provides for the reduction of time in the process of preparation of drawings and documents
  (shop drawings, Bill of quantity, QTO, etc.), And coordination between the parties.

• The traditional CAD file does not incorporate information required to be included in the projects and often the information is fragmented and discontinuous in the drawings, difficult to grasp in their entirety and complexity. BIM is a next step, the repository of targeted information, easy to query in order to create schedules and tables as needed.

• The BIM allows interoperability through the use of a common data exchange language. The standard size is the Industry Foundation Class (IFC) which is recognized by the major BIM design software (ArchiCAD, Revit, Tekla Structure, Bentley, etc.).

• The BIM design involves the use of 3D parametric models (BIM object). The items to be included in the model are aerodynamics wich collect all the information you need to:
◦implement the specific information database positioned object;
◦draw up designs through automatic systems. BIM object, for example, you can choose the graphics section of pens,
  patterns, symbols, units, etc. and automatically it will generate plans, elevations, sections produced by the Macro model.

• The BIM allows greater control of the project, a greater ease in coordination between the parties, such as the search for
  the collision of the elements, and the editorial staff of RFI (request for information), fast and punctual.

• The visual verification of the elements you can generate 3D rendered views or not, creation of specific models for mobile systems with applications that take advantage of BIM technology.
• 
The parametric BIM model which is managed throughout the life cycle of the building and always the same. After careful
  and accurate initial assessment, the model is created so that it can be updated and implemented according to the achieved steps and objectives to be pursued.
