  • 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.

  • Chapter 1: Introduction
    Chapter 1: Introduction 1.1 Preface In response to the fast growth in construction industries worldwide, design and construction firms, and professionals in Architecture, Engineering and Construction (ACE) sector, have great challenges to adopt more efficient and effective building tools to achieve client’s satisfaction by providing accurate and easier information and data more than traditional assembled 2D. Since 1992 the term of Building Information Building( BIM) appeared and started using widely as concept for digital representation of the physical and functional characteristics of a building displayed as a 3D model, with the added capability to integrate a whole array of design, and the term is changing from one developer to another such as Virtual Building by GraphiSoft and Integrated Project Models by Bentley Systems. According to The National Building Information Model Standard (NBIMS), Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle.In 2004, the National Institute of Standards and Technology (NIST) published a report stating that poor interoperability and data management costs the construction industry approximately $15.8 billion a year, or approximately 3 -4% of the total industry .A basic premise of BIM is collaboration by different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM process to support and reflect the roles of that stakeholder (Suremann, 2009) Addition to that, new dimension elements have been added to 3D concept such as 4D for time and 5D for cost to enhance the capability for life cycle management.

    Use of BIM for existing Buildings On Building Information Modeling: an explorative study Erika JOHANSSON Darek M. HAFTOR Bengt MAGNUSSON Jan ROSVALL 1 Use of BIM for existing Buildings On Building Information Modeling: an explorative study © Erika JOHANSSON Darek M. HAFTOR Bengt MAGNUSSON Jan ROSVALL Department of Informatics and Department of Construction Technology, Linnaeus University, Växjö, Sweden Linnaeus University Press Växjö, Sweden June, 2014 ISBN 978-91-87925-02-3 2 Use of BIM for existing Buildings Abstract Building Information Model (BIM) is now a well-established notion in the context of built environment management, which includes the construction industry and the facility management industry. At first sight, BIM represents the various tools that support formulation and usage of models of built environments. Vendors that develop and provide BIM technologies typically offer bold promises regarding the positive effects of the usage of BIM. These positive effects include increased efficiency, quality and safety, in the context of the whole lifecycle of a built environment. However, the main emphasis of that rhetoric is placed on the benefits gained from using BIM in the construction and maintenance of new built environments. As the overwhelming majority of built environments are made up of already existing constructions, rather than projected buildings, a key question is: what are the practices for the use of BIM for existing buildings? An explorative research study has been conducted to respond to that question. The main

  • Building Information Modeling Two Years Later – Huge Potential, Some Success and Several Limitations Written By: Ian Howell and Bob Batcheler
    Building Information Modeling Two Years Later – Huge Potential, Some Success and Several Limitations Written by: Ian Howell and Bob Batcheler Introduction Since the great Building Information Modeling (BIM) debate facilitated by Jerry Laiserin in April 2003, and reported on here in the Laiserin Letter, much has transpired with regard to building information modeling. Pilot projects have been completed, BIM systems have evolved through several versions of software upgrades, and industry leading firms are adopting BIM on live projects. Given the number of companies we have met during our research that have indicated some intention to seriously consider adopting BIM, we felt that it would be useful to document our findings to provide a basis for evaluating BIM and to examine what has been learned. First, for the uninitiated, a brief recap. CAD versus BIM – A Quick Refresher of the Basics [Regular readers of the Laiserin Letter should feel fee to skip this section and get straight to the exciting stuff below] The original premise of a CAD system was to automate the task of drafting. As such, the original focus of CAD applications was to represent 2D geometry via graphical elements, such as lines, arcs, symbols, et al. In this context, walls, for example, are merely represented as parallel lines. To establish some meaning behind these graphical elements, the concept of layering was introduced to group related elements, such as the lines used to represent walls on a given ‘wall layer.’ By doing so, discrete 2D drawing files could be generated and plotted from CAD, but more complex information, such as the relationships between elements could not be represented.

Korea generally known as a country of high technology and rapid in the world but the country also has a diversity of Korean architectural style. This led to the Korean inherit various building designs for generations. It is important for the identity of a country. JIN LI GWAN designs a building that has a value that is proud like facade. The main objective of this study is to see upon how BIM technology will help students in measuring historical building. Students from CART Polipd combined with students from Ansan University integrate BIM technology in measuring and documenting JIN LI GWAN. Research found that integrating BIM technology in measured drawing project help students to produce high accuracy documentation in a short period of time. Façade development also becomes easy with BIM technology. Drone made the process faster in documenting façade and roof for tall building. Integrating BIM technology in measured drawing make easy for documentation process involving the generation and management of digital representations of physical and functional characteristics of buildings and places. BIM technology allows students to create documentation from the data collected in short period of time. This technology also allows students to produce high detail of digital model that make it easy for visualization in the presentation.
