A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle. The emergence of BIM triggered the second digital revolution of the entire construction industry. Its emergence not only made the entire construction industry more digital and advanced but also had a profound impact on people's thinking. [1] The emergence of BIM has also improved the degree of integration of construction engineering information, providing a good amount of information-sharing platform for construction engineering projects. The concept of BIM can be traced back to the 1970s. The first software tools developed for architectural modelling appeared in the late 1970s and early 1980s, including Chuck Eastman's architectural description system and workstation products, such as GLIDE, RUCAPS, Sonata, Reflex, And Gable 4D series. Early application and hardware usage requirements were not common because they were expensive. [2] [3] The term "architectural model" (in terms of BIM in use today) was first used in the mid-1980s and was finally published in 1986 in an article by Simon Ruffle in 1985, and later used in Robert's 1986 white paper by Robert Aish. GMW Computers Ltd, the software developer of RUCAPS, discussed the use of the software at London Heathrow Airport. The first is the 1992 article by GA van Nederveen and FP Tolman. [2] [3] However, the term "Building Information Modelling" ("BIM" for short) became widely used only ten years later. [3] The emergence of BIM is a major change for the construction and architecture industry. It not only enables practitioners in the construction industry to have a more intuitive and convenient experience in architectural design and construction but also gives construction engineers more protection, in case of the site visiting and analysis accident. BIM has also various functions, not only 3D modelling and rendering but also calculation, including calculation of loads, such as wind load, snow load, self-weight etc, energy consumption, and analysis of daylighting. 2 Objective The purpose of this thesis is to popularize and introduce the importance of BIM to the construction industry and the impact of the use of BIM on the future of the construction industry. As a drawing software, but more than a drawing software, BIM can share data. BIM's help to the construction industry is very significant. To feel the overall structure of the building more intuitively and to detect 2 the safety and viewing of the building, the emergence of BIM can be said to be a major advancement in the construction industry [2]. BIM software is widely used around the world, but their popularity in different countries varies. For example, in China, the application and popularization of BIM are relatively poor compared to European. Most of the users of BIM software are young practitioners, while some older and more experienced practitioners might be more inclined to use older methods. The advent of the BIM era may cause many of these older practitioners to be abandoned by the industry. Understanding BIM and learning BIM software is therefore important. 3 Research method This thesis introduces results found from literature reviews and the web, regarding the most common BIM software and their application. An interview was also conducted to find out the usage of BIM in different industries. Information available on the web was also searched to find relevant standards used in BIM. In the process of writing the thesis, some small-scale investigations were also carried out so as to more confirm the authenticity of some data. Some advantages of the research method used in this thesis are: • Understand the history and current situation of related issues and help determine research topics. • Able to form a general impression about the research object, which is helpful for observation and access. • Able to obtain comparative data of real data. 4 BIM Workflow in the construction industry BIM is widely used and can be used in different stages of construction. The use of BIM in each stage plays an important role in that stage. 4.1 Architectural design Architectural design is the initial step of the BIM workflow. BIM is used from the initial design to the subsequent expansion and modification of the design. It is necessary to modify and optimize the model on the BIM software, and at the same time, ensure that the work is in progress, the integrity of the data in the medium avoids data loss and calculation errors. The flow chart of BIM data delivery from design concept to preliminary design is shown in figure 3.1. 3 Figure 3.1. BIM workflow from concept to preliminary design (Adapted by [2] ) In the initial stage of a project, the site data is known. The first step is to draw a draft map. The available software includes sketchbook and CAD. Then, the sketch drawn can be imported to Autodesk Revit or Autodesk Vasari software, where 3D modelling is enabled. Afterwards, the process continues with shaping the overall volume of the basic concept expression model in e.g. Autodesk Revit or Autodesk Vasari according to the project requirements. Many other BIM software can be used for this as well. The exterior design of the entire building can be completed using parametric methods. The software that can generally achieve parameterization include Autodesk Revit, Rhino, CATIA, Sketchup, and Archicad, etc. Figure 3.2 below shows the Autodesk Revit model. Parameterization refers to uploading the measurement data to the cloud to save and generate a three-dimensional model. Figure 3.2.

  • BIM Tools and Parametric Modeling
    CHAPTER2 BIM Tools and Parametric Modeling 2.0 EXECUTIVE SUMMARY This chapter provides an overview of the primary technology that distinguishes BIM design applications from other CAD systems. Object - based parametric modeling was originally developed in the 1980s. It does not represent objects with fi xed geometry and properties. Rather, it represents objects by parame- ters and rules that determine the geometry as well as some non - geometric properties and features. The parameters and rules allow the objects to auto- matically update according to user control or changing contexts. In other industries, companies use parametric modeling to develop their own object representations and to refl ect corporate knowledge and best practices. In architecture, BIM software companies have pre- defi ned a set of base building object families for users, which may be extended, modifi ed, or added to. An object family allows for the creation of any number of object instances, with forms that are dependent on parameters and relationships with other objects. Companies should have the capability of developing user - defi ned parametric objects and corporate object libraries for customized quality control and to establish their own best practices. Custom parametric objects allow for the modeling of complex geometries, which were previously not possible or simply impractical. Object attributes are needed to interface with analyses, cost estimations, and other applications, but these attributes must fi rst be defi ned by the fi rm or user. Current BIM tools vary in many ways: in the sophistication of their prede- fi ned base objects; in the ease with which users can defi ne new object families; BIM Handbook: A Guide to Building InformationModeling for Owners, Managers,Designers, Engineers, and Contractors.

  • Cad-Bim Requeriments for Masonry Design Process of Concrete Blocks
    CIB W78 2008 International Conference on Information Technology in Construction Santiago, Chile CAD-BIM REQUERIMENTS FOR MASONRY DESIGN PROCESS OF CONCRETE BLOCKS Scheer, Sérgio Associate Professor of the Construction Engineering Department at the Federal University of Paraná – UFPR. Civil Engineering Research Centre, CEP 81.531-980, Cx. Postal 19.011, Curitiba, Paraná State, BRASIL [email protected] Ayres Filho, Cervantes1 [email protected] Azuma, Fabíola2 [email protected] Beber, Michelle3 [email protected] 1,2,3 MSc candidate of the Civil Construction Postgraduate Program at the Federal University of Paraná - UFPR. ABSTRACT The masonry constructive technique of concrete blocks is a practice that contributes for a high level of industrialization in construction in addition to achieve the rationalization in this sector. The achievement of these benefits demands some design features such as modular coordination, blocks rows details and well documented and precise specifications. One solution to meet these design features without causing agility reduction during the process is the use of CAD-BIM (Building Information Modeling), which applies modeling and visualization techniques already consolidated in other industry branches. Although the CAD- BIM brings improvements in the design process, it does not provide tools aimed directly to blocks masonry design, what can cause difficulties. The goal of this work is to identify these problems through a case study in a builder office sited in Curitiba, Parana state, Brazil, which is specialized in building design of concrete blocks masonry. Based on the results of data collected in the case study and in the literature available was possible to develop a list of CAD-BIM requirements more suitable for this kind of design.
