VI RESUMO O trabalho de pesquisa dessa dissertação consiste na análise comparativa entre os métodos de elaboração de estimativas de custo de obra elaborados com base em projeto bidimensional e por sistema BIM – Building Information Modeling ou Modelagem da Informação da Construção. A fundamentação teórica abordou conceitos relacionados às atividades: 1 - orçamentação; 2 - processo de projetação bidimensional e tridimensional; 3 - aos sistemas inteligentes que gerenciam informações durante o ciclo de vida da construção, os chamados sistemas BIM. A problemática deste estudo consiste na necessidade dos órgãos públicos federais em precisar o valor estimado da obra para fins de reserva de recursos orçamentários no Plano Plurianual do Governo Federal para obras civis. A hipótese desta dissertação é que a utilização de um sistema BIM em conjunto com um sistema computacional para cálculo do orçamento permitirá calcular o valor da obra com precisão. No sentido de testar esta hipótese foi utilizado o software ArchiCAD para a elaboração do projeto de arquitetura e o Volare para a estimativa do custo da obra. Para tanto, foi desenvolvido um estudo de caso do projeto básico de arquitetura da IRF/Jaguarão – RS, elaborado originalmente em sistema bidimensional e a estimativa de custos com base no CUB/m². Dessa forma, foi possível fazer um paralelo entre o valor do orçamento obtido por um sistema bidimensional e o alcançado por meio do sistema BIM. O resultado dessa análise comparativa demonstrou que o valor estimado pelo Volare com base em quantitativos do sistema BIM é mais próximo do valor da obra do que o obtido com base em quantitativos do projeto bidimensional. Palavras Chaves: Orçamentos, Quantitativos, Estudo de Caso, BIM, ArchiCAD e Volare. VII ABSTRACT The work of research of this study consists on the comparative analysis of the manually developed method of estimating costs and the ones based on the BIM (Building Information Modeling) system. The theoretical basis dealt concepts related to: 1 - Budgeting activities, 2 - Process of bi-dimensional and tri-dimensional projecting, 3 - Smart systems that manage information during the work lifecycle of the building, called BIM systems. The problematic of this study consists on the need of federal government employees to precise shows values for estimates of construction for the purpose of reservation of budget resources in Pluriannual Plan of Federal Government to civil construction. The hypothesis of this study is that the use of a BIM system and a computer system to calculate the budget enables a precise reckoning of the construction value. To test this hypothesis the software ArchiCAD was used to develop the architectural project and Volare to estimate the construction cost. For that, it was developed a case study of the basic architectural project of IRF/Jaguarão - RS, originally evolved in bi- dimensional system and estimated budget based on CuB/m². Thus, it was possible to note similarities between the value of the manually obtained budget and the one obtained by BIM systems. The result of this comparative analysis showed that the value estimated by Volare was really more approximate to the contracted amount than the one obtained based on quantitative of the bi- dimensional project. Key words: Budgets, Quantitatives, Case Study, BIM, ArchiCAD and Volare.

  • 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.

  • On Building Information Modeling: an Explorative Study
    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.
