A private telecom carrier partnered with the University of Waterloo to examine opportunities to improve their asset management processes. A reliance on traditional CAD technology made it difficult to generate an enterprise view of operational assets, such as poles and cables, since CAD documents were limited to neighbourhood scale coverage. The CAD documents had to communicate logical and locational properties of these assets. These requirements were often at odds since the elements in these CAD documents were occasionally moved to clarify logical aspects, the most common being connectivity with other telecommunications hardware. Elements within the drawings were also restricted to two dimensions, a legacy of early adoption of CAD technology within the telecom carrier. Developments in GIS and architectural technology that have occurred since the introduction of CAD offer opportunities to manage assets using enterprise geospatial systems with three dimensional content. Prominent technologies and standards, such as CityGML and Oracle, will be examined to develop a model to support requirements related to service location. A service location for this paper is a site that requires the deployment of specific resources to meet the needs of a service request. Additionally, as location displacement is an issue that needs to be addressed, an evaluation of data quality processes related to location will be presented. The results from this evaluation will then be used to construct a final standards based 3D geospatial service location model, one that should address the needs of the partner carrier.

As Building Information Modeling (BIM) applications become more sophisticated and used within other knowledge domains, the limitations of existing data exchange and sharing methods become apparent. The integration of BIM and Geographic Information System (GIS) can offer substantial benefits to manage the planning process during the design and construction stages. Currently, building (and geospatial) data are shared between BIM software tools through a common data format, such as Industry Foundation Classes (IFC). Because of the diversity and complexity of domain knowledge across BIM and GIS systems, however, these syntactic approaches are not capable of overcoming semantic heterogeneity. This study uses semantic web technology to ensure the highest level of interoperability between existing BIM and GIS tools. The proposed approach is composed of three main steps; ontology construction, semantic integration through interoperable data formats and standards, and query of heterogeneous information sources. Because no application ontology is available to encompass all IFC classes with different attributes, we first develop an IFC-compliant ontology describing the hierarchy structure of BIM objects. Then, we can translate the building's elements and GIS data into semantic web standard formats. Once the information has been gathered from different sources and transformed into an appropriate semantic web format, the SPARQL query language is used in the last step to retrieve this information from a dataset. The completeness of the methodology is validated through a case study and two use case examples.

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively. This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH™ which change over time depending on the current camera position relative to the planet surface. Our method is integrated into Uniview and allows Uniview to render high resolution planet geometry with dynamic texture composition and with a surface positioning system that does not suffer from precision issue.

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.

[pt] O principal objetivo deste estudo foi avaliar e validar como funcionalidades da Modelagem da Informação da Construção (BIM) podem interagir com princípios da construção enxuta para contribuir para o desenvolvimento sustentável em projetos de construção e alcançar projetos de maior qualidade. Para este fim, primeiramente uma breve revisão de cada um destes conceitos foi introduzida, seguida por uma extensiva e estruturada revisão da literatura, buscando combinações par a par destes tópicos. Os resultados desta revisão deram origem à uma matriz que que consolidou as interrelações, que foram destacadas e explicadas. Para validar algumas destas interrelações, um plug-in foi proposto e implementado em um ambiente de visualização BIM para ajudar o usuário a decidir pelo melhor projeto dentre diferentes alternativas, considerando também a perspectiva do usuário em termos do que mais gera valor ao projeto. Para ilustrar e validar a usabilidade e importância do plug-in, o projeto de um galpão com determinados requerimentos foi considerado. Quatro alternativas de projeto foram modeladas considerando diferentes tipos de superestrutura e envelope das edificações, bem como variados materiais. Estes modelos foram exportados como arquivos IFC e então importados no ambiente BIM. Através do plug-in desenvolvido, foi então importada uma base de dados externa e calculados os indicadores de custos gerais, emissões de CO2 e comforto térmico para cada modelo baseados nos dados contidos nos elementos e na base de dados importada. Finalmente, foram consideradas ponderações inseridas por usuários para cada indicador e exibidos os resultados em forma de gráficos, indicando a melhor opção através de um Método de Decisão de Múltiplos Atributos. Apesar de os modelos utilizados nesta pesquisa terem sido hipotéticos e mais indicadores serem necessários para melhores resultados, foi possível verificar que análises automatizadas podem otimizar tarefas de tomada de decisão que em outras circunstâncias seriam ineficientes e imprecisas. Desta forma, algumas das interações percebidas foram validadas e a importância da integração entre os conceitos foi confirmada. / [en] The main purpose of this study was to evaluate and validate how Building Information Modeling functionalities could interact with lean construction principles to support sustainable development in building design and deliver higher quality projects. To that end, first a brief introduction to each of these concepts was introduced, followed by an extensive and structured literature research looking for pairwise combination of these topics. The results of this review generated a matrix that brought up interactions, which were highlighted and explained. To further validate some of these interrelationships, a plug-in was proposed and implemented on a BIM enabled visualization environment to help the user decide the best design between alternatives, while considering his perspective on what generates value to the project. To illustrate and validate the usability and importance of the plug-in, the design of a warehouse with certain requirements was considered. Four design alternatives were modelled considering different types of superstructures along with the building envelope and varied types of materials. These models were exported as IFC files and then imported to the BIM environment. The plug-in then imported an external database and calculated general costs, CO2 emissions and thermal comfort indicators for each model based on data contained on elements and the imported database. Finally, it considered user weightings on each indicator and graphically displayed results indicating which of the options would be the best through a Multiple Attribute Decision Method. Even though the used models were hypothetical and more indicators would be required for more robust results, it was possible to verify that automated analysis considering indicators can optimize decision making tasks that otherwise would be inefficient and innacurate. This way, some of the perceived interactions were validated and the importance of integrating these concepts was confirmed.

[pt] Embora o uso de tecnologias de informação na construção seja de extrema relevância para o aumento da produtividade em busca do desenvolvimento sustentável, não se encontra na literatura orientações claras para sua implantação. O propósito deste trabalho é identificar barreiras e benefícios para propor diretrizes de implantação do Building Information Modeling (BIM) no Brasil. O protocolo adotado para a pesquisa é qualitativo e quantitativo, contendo as etapas de revisão sistemática da literatura, estudo empírico, proposição de diretrizes, validação e conclusão. Há evidências na literatura de barreiras em tecnologias, envolvendo limitações de softwares e falta de interoperabilidade, frequentemente citadas. Além disso, identificou-se falta de colaboração e diferentes expectativas entre disciplinas em fluxos de trabalho. Sobretudo, a falta de conhecimento, a resistência à mudança e a descontinuidade das equipes afetam a implantação de BIM. Após comparar o que foi observado no estudo empírico com o identificado na literatura, analisando as barreiras e benefícios, propõem-se diretrizes envolvendo processo, tecnologia e pessoas para guiar a implantação de BIM. Finalmente, é utilizada uma pesquisa do tipo survey para validação do proposto. / [en] Although the use of information technologies in construction is highly relevant for increasing productivity seeking sustainable development, the literature lacks clear guidelines for its implementation. The purpose of this study is to identify barriers and benefits to propose a set of guidelines for implementation of Building Information Modeling (BIM) in Brazil. The study protocol is qualitative and quantitative, containing the stages of systematic literature review, empirical studies, guidelines proposal, validation and conclusion. Evidence in the literature points to barriers in technologies, involving frequently cited software limitations and lack of interoperability. Lack of collaboration and different expectations between disciplines involved in the work flow were also identified. Above all, lack of knowledge, resistance to change, and team turnover affects the implementation of BIM. After comparing the observations from empirical studies and the literature, analyzing barriers and benefits, guidelines are proposed that involve process, technology, and people to guide the implementation of BIM. Finally a survey is used to validate the findings.

Building Information Modeling (BIM) är en relativt ny arbetsmetod i byggbranschen som allt fler företag anammar i sina olika projekt. Med hjälp av BIM kan projektets arbete effektiviseras redan i ett tidigt stadie. Då man till exempel kan utföra kollisions kontroller i skapade 3D modeller de olika aktörerna i mellan redan i projekteringsfasen och på så vis undvika problem när byggarbetet väl har startat. BIM processen består av tre delar. De kallas 3D, 4D och 5D vilket omfattar 3Dmodulering, tidplanering och kostnadskalkylering. I denna rapport riktas fokus på tidplaneringsfasen för att ge en bild av hur arbetet skulle kunna bli bättre om BIM användes för att tidplanera och dess hinder i utvecklingen i användningen av BIM. För att få en uppfattning av hur det var att planera utfördes en jämförelse av Gantt planering och Flowline planering. Där en Flowline planering upprättades från en befintlig Gantt planering för att se hur de olika metoderna skiljer sig åt. / Building Information Modeling (BIM) is a relatively new method of working in the construction industry that more and more companies embrace in various projects. With the help of BIM project work efficiency can be increased at an early stage. For example, I can perform collision checks in the created 3D models of the various players already in the planning phase, this can help avoiding problems when the construction work has started. BIM process consists of three parts. They are called 3D, 4D and 5D and include 3D visualization, scheduling and costing. In this report the focus is mostly on time planning phase to provide a picture of how the work could be better if the BIM was used to planning and its obstacles in the development of the use of BIM. To get an idea of how the planning was carried out as a comparison of the Gantt planning and Flowline planning was made. Where a Flowline plan was established from an existing Gantt planning , then to see how the methods are different from each other.
