BIM flows
Introduction
Building information modeling (BIM, Building Information Modeling), also called building information modeling,[1] is a set of processes and methods for the generation and management of data of a building or work of architecture and/or civil engineering during its life cycle "Life cycle (environment)"), using a digital model shared between different actors in the value chain. The objective is to reduce time and resources in the design, construction and management of the asset. BIM is based on interdisciplinary collaboration and the exchange of information with other software tools, such as GIS, etc. To ensure consistent information management and facilitate data exchange, BIM is based on various international standards.[2].
The most used BIM modeling and management software in this field of architectural and civil design are Autodesk Revit, ArchiCAD and Navisworks.
Origin of BIM
There are several points of view about the origin of this concept. Pioneering companies in the application of the BIM concept were Graphisoft"),[3] from Hungary, which implemented it under the name Virtual Building since 1984[4] in its ArchiCAD program, as well as VectorWorks") in 1985 (previously MiniCAD from Diehl Graphsoft) recognized for being the first CAD software for personal computers capable of creating both 2D and 3D drawings and also incorporating language capable of producing reports;[5] Autodesk began using the BIM concept since 2002 when it bought the Texas company Revit Technology Corporation for 133 million dollars,[1] while others postulate that it was Professor Charles M. Eastman, of the Georgia Tech Institute of Technology*,* who first disseminated the concept of building information model, as a synonym for BIM, in the early seventies in numerous books and academic articles.[6] However, there seems to be a general consensus that Jerry Laiserin was the one who popularized it as a common term for the digital representation of construction processes, with the objective of exchanging and interoperationalizing information in digital format. This capability today is offered by different technology providers such as: Bocad, Tekla, Nemetschek, Sigma Design, Autodesk, StruCad by AceCad Software, Bentley Systems, AVEVA Solutions, Graphisoft, ACCA software, sds/2 by Design Data (leader in detail engineering), CADDetails, Dlubal Software, Esri, among others.
