Dessa forma, a tecnologia BIM (Building Information Modeling), que significa Modelagem de Informação da Construção, é um conjunto de informações geradas e mantidas no decorrer de todo o ciclo de vida de uma edificação. Esta pesquisa apresenta como objetivo a análise das contribuições da utilização de sistemas BIM, mais precisamente das ferramentas Revit e Navisworks, além do uso do software Ms Project, voltados para o melhor planejamento de obras da construção civil. O software Revit será usado para realizar a modelagem 3D do projeto escolhido e com os quantitativos de materiais gerados pelo programa vai ser realizado o levantamento de custos das principais atividades da obra em estudo. No Ms Project deverá ser criada a Estrutura Analítica do Projeto (EAP). E em seguida, os dados obtidos pelos programas serão incorporados no sistema Navisworks, com o intuito de gerar o planejamento 4D (os elementos gráficos da edificação podem ser atrelados ao cronograma da obra) e 5D (agrega-se a dimensão custo ao modelo tridimensional) da edificação. É de fundamental importância incorporar novas tecnologias no processo de construção, assim como os sistemas BIM, capazes de contribuir significativamente para a redução de custos e para a melhoria da qualidade e produtividade dos empreendimentos e do setor de construção civil como um todo. Deste modo, com esse estudo será possível avaliar a importante contribuição dos sistemas BIM em relação ao planejamento das obras. / Currently, the use of smart computer systems focused on integrated practice, from the design phase to the implementation and maintenance of an architectural project, become a great difference in the organizational environment. Thus, BIM (Building Information Modeling), is a set of information generated and maintained during the entire life cycle of a building. This research aims to analyze the impacts of BIM systems, such as Revit and Navisworks, and MS Project software, to building planning. The Revit BIM software will be used to perform 3D modeling of the chosen project and with the quantitative materials generated by the program we performed a study of costs of the main activities of the project under study. In Ms Project will be created to Work Breakdown Structure (WBS). Then, the data obtained by the programs will be incorporated into Navisworks system, in order to generate the 4D planning (graphic elements of the building can be linked to the work schedule) and 5D (adds the dimension cost three-dimensional model) the building. It is vital to incorporate new technologies in the construction process, as well as the BIM systems capable of contributing significantly to reducing costs and improving the quality and productivity of enterprises and the construction industry as a whole. Thus, with this study will evaluate the important contribution of BIM systems in relation to the planning of the constructions.

Previous issue date: 2012 / Resumo: Dentro do universo dos projetos digitais baseados no desempenho, existe uma categoria que usa o desempenho não apenas como meios avaliativos, mas, acima de tudo, como instrumento de transformação das ideias e conceitos em matéria e forma arquitetônica. Usa-se mecanismos digitais que incorporam princípios de informatização à estruturas computacionais. Esta categoria de projeto digital é denominada Projeto Performativo. O presente trabalho tem como objetivo geral formular uma estrutura conceitual de processo de projeto digital que explique a prática de Projeto Performativo. A questão que se coloca é, quais são os pressupostos da prática de projeto que visem a incorporação do desempenho como propulsor do processo de geração da forma arquitetônica? Duas hipóteses foram investigadas neste contexto. A primeira hipótese foi que o modelo de projeto digital denominado performativo tem como pressuposto um processo de projeto baseado na colaboração, no processo de projeto automatizado, na modelagem paramétrica e na interoperabilidade. A segunda hipótese foi que é possível simular a prática de Projeto Performativo segundo estes pressupostos em experiências didáticas de atelier de projeto. Para atender aos objetivos gerais e específicos e responder às hipóteses levantadas, esta pesquisa desenvolveu uma investigação por meio da pesquisa exploratória e explicativa. A primeira iniciou com a busca da familiarização do problema por meio de uma revisão bibliográfica e de estudos de casos. Os estudos de casos foram desenvolvidos em escritório de projeto referência internacional. A segunda ocorreu pelo desenvolvimento de uma pesquisa experimental. Da análise de referencial teórico e dos estudos de casos emergiu uma estrutura conceitual para o projeto performativo caracterizada: pela prática essencialmente colaborativa multidisciplinar na síntese arquitetônica resultando em mudanças na apropriação das autorias; uso simultâneo de técnicas de projeto analógicas e digitais resultando na co-existência de estágios de decisão manuais, semi-automatizados e/ou automatizados; na modelagem paramétrica com maior ênfase ao projeto topológico substituindo tradição tipológica; na interoperabilidade marcada pelo fluxo de informação analógico e digital viabilizado pelo BIM - Building Information Modeling - como processo evolutivo fragmentado que permite liberdade necessária ao processo. A estrutura conceitual comporta a coexistência em um mesmo processo de projeto digital de diferente de métodos baseados no desempenho para resolução de diferentes partes ou sistemas do edifício. Essa coexistência de diferentes modelos e métodos permite resolver problemas complexos de projeto, abrigar e pacificar a controversa relação forma X função. O resultado de ordem experimental relacionado a validação da estrutura conceitual em experiência de ateliê de projeto confirmou que, apesar das limitações e restrições deste universo, foi possível estimular a morfogênese de modo criativo e eficiente. As experiências com o uso do Método BESO para a geração da forma pelo desempenho estrutural permitiram: criar múltiplas soluções de projeto, dentro de um espaço de soluções; utilizar facilmente o ferramental (mesmo não se conhecendo alguns conceitos relacionados ao comportamento da estrutura); possibilitar a realização de um número grande de ações cognitivas, num curto intervalo de tempo; realizar novas explorações formais; valorizar o desempenho estrutural como motor de geração da forma do edifício / Abstract: Within the universe of digital designs based on performance, there is a category that uses performance not only as evaluative means, but, above all, as a transformation tool for ideas and concepts in matter and architectonic form. It uses digital mechanisms that incorporate computational principles to computational structures. This category of digital design is called Performative Design. The general aim of the present paper is to formulate a digital design process conceptual framework that explains the Performative Design practice. The question to be made is what are the design practice assumptions aimed at the incorporation of performance as the propeller of the architectonic form generation process? Two hypotheses were investigated in this context. The first hypothesis was that the digital design model called performative has as assumption a design process based on cooperation, automated design process, parametric modeling, and interoperability. The second hypothesis was that it is possible to simulate the practice of Performative Design according to these assumptions in design workshop teaching experiments. In order to meet the general and specific aims and answer the raised hypotheses, this research has developed an investigation through exploratory and explanatory research. The first one started with the familiarization of the problem through literature review and case studies. The case studies were carried out in international reference design office. The second was done with experimental research. The analysis of the theoretical reference and case studies gave origin to a conceptual framework for the performative design characterized by the following factors: the essentially cooperative multidisciplinary practice in the architectonic synthesis resulting in changes in the appropriation of authorship; the simultaneous use of analogical and digital design techniques resulting in the coexistence of manual, semi-automated and/or automated decision stages; parametric modeling with emphasis on the topological design replacing typological tradition; interoperability marked by the analogical and digital information flow made possible by BIM - Building Information Modeling - as a fragmented evolutional process which allows the necessary freedom to the process. The conceptual framework involves the coexistence, in the same process of digital design, of different methods based on performance for the resolution of different parts or systems of the building. Such coexistence of different models and methods allows the solution of complex design problems, and also harbors and pacifies the controversial relationship form X function. The experimental result related to the validation of the conceptual framework in the experience of design workshop has confirmed that despite the limitations and restrictions of this universe, it was possible to stimulate morphogenesis in a creative and efficient way. The experiences with the use of the BESO method for form generation by structural performance have allowed the following: to create multiple design solutions within a space of solutions, to easily use the tooling (even not knowing some concepts related to the structure behavior), to allow the running of a large number of cognitive actions in a short time, to make new formal explorations, to value the structural performance as the motor of building form generation / Doutorado / Arquitetura e Construção / Doutor em Engenharia Civil

Project Time and Cost Control Using Building Information ModelingZhang, Dalu January 2013 (has links)
Although the construction industry has been evolving for centuries and researchers have been seeking innovative solutions for decades, diverse challenges still exist in making the construction process faster, safer, cheaper and more accurate. It is believed that Building Information Modeling (BIM) can lead to greater efficiency through the incremental collaboration. The data in BIM system is extremely useful and can be generated to optimize the project delivery processes. However, since BIM increases the project design cost and requires a big learning curve, project participants are concerned about the cost of project, which has hindered the adoption of BIM for the project delivery. This paper, using a case study, describes how BIM functions to help cut down costs, optimize schedule, and benefit the project participants. The analysis of project cost and time control focuses on life cycle. The recommendations for the future use of BIM are made generally.

BIM-Based Turnover Documentation and Information System for Facility ManagementWang, Zhulin 30 August 2019 (has links)
Facility management (FM) is a profession that deals with diverse types of information and requires multiple specific types of knowledge and skills. The technology of facility information management develops slowly, compared to the fast-changing building and construction technologies. With its popularity in facility design and construction, Building Information Modeling (BIM) is promising to reform the information and communication needs of facility managers. Yet there are still a lot of untapped potentials in using BIM during a facility's post-construction phases. The purpose of this study is to develop insights on the possible ways to improve facility information management with BIM from the real world examples and from literature. To start with, two case studies are conducted to get a better understanding of the current practice of facility information management. One is on the dynamic flow of information from the owner's perspective. The other is on the delivery of facility information to the owner from the contractor's perspective. The two case studies provide a close and holistic look at the real world of FM, which facilitates the interpretation of literature in the next stage. A comprehensive literature overview is conducted on the application of BIM in FM. The overview covers the benefits and obstacles of BIM application, various types of FM information, and technologies that enable more functions to manage FM information. / Master of Science / After the completion of building construction, the contractors will turn over the building to the owner for his occupancy and use, also called facility management (FM). Along with the building, the information related to the building is also handed over to the owner to support their operation and maintenance of the building, like the manuals that go with a product. This facility information encompasses multiple disciplines regarding the building. The management of this building information is difficult without the support of information technology. Building information modeling (BIM) is a promising technology for information management that intuitively links information to 3D objects. It is already popularly adopted in design and construction, but its continued support for building owners on information management is still at the exploratory stage. The purpose of this study is to develop insights on the possible ways to improve facility information management with BIM to support owners as they operate and maintain the building. To start with, two case studies are conducted to get a better understanding of the current practice of facility information management. One is on the dynamic flow of information from the owner’s perspective. The other is on the delivery of facility information to the owner from the contractor’s perspective. The two case studies provide a close and holistic look at the real world of FM, which facilitates the interpretation of literature in the next stage. A comprehensive literature overview is conducted on the application of BIM in FM. The overview covers the benefits and obstacles of BIM application, various types of FM information, and technologies that enable more functions to manage FM information.

Adapting building information modeling (BIM) for affordable & sustainable housingDowhower, Justin Firuz 01 November 2010 (has links)
The purpose of this thesis is to determine if Building Information Modeling (BIM) is an effective means for encouraging stakeholder collaboration throughout the building design/construction process and improving upon affordable and sustainable strategies for infill housing development.
The research methodology includes literature reviews, interviews, case studies, simulations, and experimentations. Literature reviews include documentation regarding BIM, housing affordability and policy, sustainable design strategies, and integrated design practice. I conducted interviews with local stakeholders who had participated in local affordable/sustainable housing projects. The primary case study was the Alley Flat Initiative (2003-2010) which I had the opportunity to be involved with in various capacities as a participant observer. Simulations were performed using a BIM software tool to ‘redesign’ the first Alley Flat Initiative prototype and compare design workflows. Finally, experimentation was done involving the instruction of BIM software and exploring its use within an academic design studio environment.
The findings indicate four significant conclusions. First, the research suggests that inflated soft project costs (overhead, administration, and services) can be reduced if local city governments were to adopt BIM in conjunction with housing review and permitting processes. In addition, the city could use BIM data to quantify building impacts on energy and resources over time. Second, sustainability innovation can be easier to integrate within a BIM workflow due to the high-capacity of the software to exchange information with third-part analysis tools. One particular barrier that must be overcome, however, are financial barriers due to software and staff training costs associated with BIM technology. Third, BIM requires ‘front-loading’ projects with more information earlier in the design process, which encourages greater transparency and more direct collaboration between stakeholders. A fully leveraged BIM workflow may not be feasible beyond local small-scale architects and builders due to the relatively steep learning curve and higher software costs, but a hybrid approach might be possible depending on how residential construction practices and BIM software development evolves in the near future. And fourth, BIM can make project information centralized, accessible, and long-lasting – serving as a communication and learning tool across disciplines and between expert and non-expert participants.
The product of this research includes recommendations for all stakeholder groups engaged in leveraging BIM for affordable and sustainable housing development. Additional related topics of inquiry which fell outside the scope of this research are also included for future investigation. / text

Developing Building Information Modeling (BIM) Guidelines for Campus Planning and Facilities Management at Worcester Polytechnic Institute (WPI)Padhye, Purvashri V 31 January 2017 (has links)
The development of Building Information Modelling (BIM) guidelines for campuses and universities has evolved on a case-by-case basis and there is no standard format in the development of these guides. There are however, common elements in these guidelines. This study reviews the applications of Building Information Modeling (BIM) from the perspective of owners of higher education campus facilities and proposes a structured approach to develop documented guidelines to assist the owner’s staff in the use of BIM, primarily with existing facilities. More specifically, this study proposes a set of guidelines to assist the Facilities Management department at Worcester Polytechnic Institute (WPI) in using BIM for their existing campus facilities. Since 2005, WPI has been using some components of BIM in the design and construction of new facilities and has extended BIM uses to support facilities and space management in some of the existing buildings. Some positive experiences and benefits have been derived from these applications, but to date no formal and systematic approach has been established in documenting and organizing processes for the different BIM uses on campus. The objective of this research project is to conduct an extensive review of documented approaches and guidelines for BIM uses developed by other universities and incorporate the different experiences with the use of BIM at WPI to create a set of formal guidelines exclusively for WPI for the efficient implementation of BIM in future design, construction, renovation, facility, and space management of a facility. The research collected information from the WPI Facilities Management department through surveys and interviews, to better understand the current issues associated with facility management and space planning. A case study analysis that involved the use of 3D Building Information Models of several buildings on the WPI campus was performed to validate the possible use of the BIM in the efficient delivery of information for new and renovation projects as well as for its ability to benefit in the space planning process. Existing documented guidelines developed by five other universities that have pioneered the development of their guides were also reviewed to determine common elements in their BIM-based practices and to incorporate these when applicable into the BIM guide for WPI in such a way that will effectively contribute to the BIM adoption and standardization of procedures reflecting the unique characteristics of this institution. This study identifies the benefits of utilizing BIM and standardization through the BIM guide primarily for existing construction and facilities management. The attempt to identify commonalities and standard pieces to develop a BIM guide for WPI will help improve overall operational efficiency and productivity of the organization. This provides a unique opportunity to be engaged in the process of standardization, using existing content as a reference to achieve harmonization of concepts, terms, definitions and the overall structure or framework that the documented guide is delivered within. The outcome is a WPI-BIM guide which will help assist facility owners in developing an overall BIM strategy that supports the organization’s core goals, develops the necessary contract conditions, and generates implementation plans to successfully execute BIM within the organization.

Knowledge formalization and reuse in BIM-based mechanical, electrical and plumbing design coordination in new construction projects using data mining techniquesWang, Li, 1987- 24 February 2015 (has links)
In the Architecture, Engineering and Construction (AEC) industry, inadequate collaboration between project stakeholders and disciplines often leads to conflicts and interoperability issues. Research has been conducted in knowledge formalization to bridge the knowledge gaps and information silos. Formalizing construction knowledge is challenging to formalize because most construction knowledge implicitly resides in the minds of construction experts, which is difficult to represent in a formal and explicit manner. The proposed study is built upon previous research findings, and attempts to formalize tacit knowledge in Mechanical, Electrical and Plumbing (MEP) design coordination by capturing necessary information with a model-based information capture system and reasoning about the captured data with data mining techniques. The vision of this research is that the formalized knowledge can be used to provide guidance for early design review incorporating construction considerations, facilitate structured learning from past experience, as well as train novice engineers. In summary, this research has three main contributions. First, this research presents a formalized knowledge representation schema to capture process knowledge in design coordination, which was successfully implemented in a model-based knowledge capture system developed by the author. Second, a model-based knowledge capture system was developed to store clash information in the form of categorized features and link such categorized information directly to the relevant model elements, which can also facilitate organization and management of clashes and supports searching and grouping functions. A prototype system was developed as a plugin to a widely used BIM-based design coordination application and was demonstrated with project data gathered from three new construction projects in the United States. Third, this research applied data mining techniques for knowledge discovery and reuse in MEP design coordination. Classification models were developed to provide predicted solutions for identified clashes based on historical data. The classification algorithms that produced the best results were selected, which reached precision rates of over 70%. The effectiveness of the classification models was tested in a novice experiment. / text

Framework for rating the sustainability of the residential construction practiceMah, Don 06 1900 (has links)
Sustainable development issues and environmental concerns continue to gain headlines as demand within Canada’s residential construction industry escalates. Current construction practices adhere to traditional methods of construction, with inherent weaknesses such as high labour costs, negative environmental impact during and after construction, and minimal technological advancement. Many programs exist to rate building environmental performance, including Leadership in Energy and Environmental Design (LEED) and Built Green, which are primarily performance-based, not practice-based evaluations. Considerable research has supported these performance ratings; however, there has been very little research in construction practice ratings. Hence, the purpose of the research presented in this thesis is to bridge this gap by proposing a construction practice rating program in order to challenge builders’ claims of being sustainable. Although rating programs should include measurements of both performance and practice—given that great performance does not equal great practice, particularly if the standard of performance achievement is low, current programs are based on performance alone. The goal of this thesis is to enhance the sustainability of the residential construction practice through the incorporation of sustainability evaluation rating tools. To achieve this goal, a framework has been developed which encompasses sustainability rating tools that include an integrated construction practice rating program, an application of Building Information Modeling (BIM) for carbon dioxide (CO2) emissions quantification, and implementation of a mathematical linear optimization model as a tool that minimizes cost while incorporating user-defined preferences and numerous environmental criteria under a green building rating system. CO2 emissions of various house construction stages are quantified and utilized in a 3D BIM. Application of the proposed framework is demonstrated in a case study with findings that show the weak results of sustainability ratings for a particular home builder. Hence, the findings in this research demonstrate a residential builder’s ability to measure his sustainability efforts and enhance construction practices based on a rating analysis. The introduction of BIM for quantifying emissions in the construction process is found to be of significant value. / Construction Engineering and Management

A Case Study of the Use of BIM and Construction Operations Building Information Exchange (COBie) for Facility ManagementJawadekar, Salil 2012 August 1900 (has links)
This study investigates the use of Building Information Modeling (BIM) and COBie for Facility Management on three projects where these concepts were used. Factors which affect these concepts are identified through a literature review. The study is divided into the sections of Responsibility for database formulation, Characteristics of database, Technology and Effect on work order response times. A qualitative analysis is conducted to study the application of these concepts and identify any problems encountered. A case study is conducted on three projects where BIM and COBie were used for facility management. It is found that though the database generated by using these concepts is useful for preventive maintenance, the data gathering and formulation process needs to be started during the design and construction phase to make use of BIM for facility management functions like space allocation, 3D mapping, building automation etc. This study can be used as a reference for further research based on quantitative analysis of the factors studied in the case study.
