Quando se refere à adoção de recursos tecnológicos nesta etapa do ciclo de vida da edificação, é comum relacioná-los a métodos tradicionais de operação, uma grande quantidade de documentos, que geralmente não são achados quando necessário, ou recursos utilizados para desenvolver a manutenção preditiva. Este cenário não é diferente na Faculdade de Arquitetura da UFBA (FAUFBA), onde os processos de operação e manutenção seguem padrões tradicionais, de pouca eficiência e eficácia, que dependem de departamentos como a Superintendência de Meio Ambiente e Infraestrutura da UFBA (SUMAI), responsável pela manutenção e conservação dos campi de Salvador: campus Federação / Ondina, campus do Canela, das unidades dispersas e também do campus Anísio Teixeira em Vitória da Conquista. O presente trabalho aborda a utilização da tecnologia CAFM em Instituições de Ensino Superior. Para tanto, foram analisados estudos de caso sobre a aplicação de CAFM na operação e na manutenção de Universidades nacionais e no exterior. Foram identificadas as dificuldades e a metodologia adotada para a implementação da tecnologia, que propõe a concentração de informações essenciais ao processo de gestão da edificação. Diante de recursos promissores, desde a gestão de instalações físicas à gestão de pessoas, a FAUFBA foi utilizada como objeto de trabalho para a implementação do Sistema de Alocação de Espaços em uma aplicação de Facilities Management. Para este propósito, foram utilizados modelos BIM das edificações que compõem a FAUFBA para a realização de testes. Ressaltase a importância da precisão dos dados alfanuméricos ou geométricos, visto que, este é um sistema de banco de dados espacialmente referenciado, ou seja, um repositório de informações, que é de grande valor durante a etapa de operação e manutenção da edificação. / . / In general, it is difficult to associate such advanced technology resources with the way that operation and maintenance in today's buildings is conducted. Regarding the adoption of technological resources at this stage of edification life cycle, it is common to relate them to traditional methods of operation. Usually a large number of documents are not found when necessary, or resources used to develop predictive maintenance. This scenario is no different in the Faculty of Architecture of UFBA (FAUFBA), where operation and maintenance processes follow traditional, lowefficiency and efficacious standards, which depend on departments such as the UFBA Superintendence of the Environment and Infrastructure (SUMAI), responsible for the maintenance and conservation of the campuses of Salvador: Federação / Ondina campus, Canela campus, dispersed units and also the Anísio Teixeira campus in Vitória da Conquista. The present work deals with the use of CAFM technology in Higher Education Institutions. Therefore, we analyzed case studies on the application of CAFM in the operation and maintenance of national universities and abroad. We identified the difficulties and the methodology adopted for the implementation of the technology, which proposes the concentration of essential information to the process of building management. Considering the necessities of the university with regards of management of physical facilities and personnel, it was used as a work object for the implementation of the Space Allocation System, using Facilities Management. For this purpose, BIM models of the buildings that make up the FAUFBA were used to carry out tests. The importance of the precision of the alphanumeric or geometric data is emphasized, since this is a spatially referenced database system - a repository of information, which is of great value during the stage of operation and maintenance of the building.

Buildings in the Digital Era : An Explorative Study of Digital Twins in the Built Environment

Kästel, Siw Kristine, Wallén, Joanna January 2024 (has links)
In recent years, digital twins (DT) have gained traction in enhancing operation and maintenance procedures across various industrial sectors, such as manufacturing, energy, and aerospace. Yet their utilization remains more limited in the built environment. The aim of this paper is to investigate the current conceptualizations of DTs within the context of the Swedish built environment, shedding light on the maturity of DTs for built assets and the key value drivers influencing their adoption. The study reveals that DTs for built assets are in early developmental stages, lacking the maturity required to encompass the full spectrum of attributes inherent in a conventional DT. Despite stakeholders labeling these initiatives as DTs, our findings indicate a closer alignment with the concept of BIM-based digital models. This observation resonates with existing literature, highlighting the absence of a universally accepted definition for DTs. Within the Operations and Maintenance (O&M) phase, we have identified the following four primary value drivers shaping the adoption of BIM-based DTs: 1) commercial transparency and trusted transactions, 2) efficiency and cost reduction in routine operations, 3) operational continuity, and 4) added services. These findings contribute to the ongoing discourse surrounding the convergence of BIM and DTs, offering insights into the practical implications and value propositions that drive the integration of these technologies within the built environment. / Under de senaste åren har användningen av digitala tvillingar (DT:ar) blivit allt vanligare för drift- och underhållsförfaranden inom olika industrisektorer, såsom tillverkning, energi och flyg- och rymdindustrin. Användningen är dock fortfarande begränsad inom bygg- och fastighetsbranschen. Syftet med denna studie är att undersöka de nuvarande konceptualiseringarna av DT:ar inom ramen för den svenska fastighetsbranschen, belysa mognaden hos tekniken och undersöka de viktigaste värdedrivande faktorerna som påverkar utvecklingen och användningen i drift- och underhåll av fastigheter. Studien visar att användningen av DT:ar i fastighetsbranschen befinner sig i ett tidigt utvecklingsstadie och att begreppet inom industrin inte helt överensstämmer med visionen kring konceptet. Resultaten stämmer överens med befintlig litteratur, som belyser avsaknaden av en allmänt accepterad definition för DT:ar. I drift- och underhållsfasen har vi också identifierat följande fyra primära värdedrivande faktorer för användingen av BIM-baserade DT:ar: 1) kommersiell transparens och pålitliga transaktioner, 2) kostnadsbesparingar i rutinmässigt drift- och underhållsarbete, 3) kontinuerligt driftsarbete, samt 4) tilläggstjänster. Resultaten från denna studie bidrar till den pågående diskussionen om koncepten BIM och DT, och ger ytterligare insikt i de praktiska värdeskapande processerna och belyser användningsområden av DT:ar i fastighetsbranschen.
