Purpose: The research goal was to investigate the main barriers faced by a large Brazilian construction company in their efforts to thoroughly implement BIM. This study focused on the analysis of understanding the barriers to BIM adoption and the usage of 3/4 dimensions (3D/4D) on the development of an infrastructure project.Research methodology: The research methodology was exploratory and qualitative, carried out through a single-case study approach made upon bibliographical research, company document analysis, project document analysis, interviews, informal conversations, and observations. The research methodology was developed in six months (from June to December 2019) divided into three main phases: phase 1: definition and design; phase 2: preparation and collection; phase 3: data analysis and conclusion. Data collection was developed using a semistructured research protocol with two different semistructured questionnaires: the first questionnaire aimed at collecting data regarding BIM implementation in the company’s organizational context; the second one focused on the understanding of BIM adoption in the project and on the investigation of the main barriers related to the usage of 3D and 4D modeling in the project studied.Findings: Regarding BIM implementation in the company, although the company studied is a construction company in the infrastructure sector, BIM was considered more efficient in the design phase and flawed in the construction phase. Findings have shown that BIM has improved the information management of the design itself and its interface with the construction phase. In relation to the usage of BIM in the project, a more collaborative work environment was noticed due to the effectiveness of communication between the design and construction teams on the job site. With respect to the usage of 3D/4D modeling in the project studied, the difficulties in extracting information from the 3D model have disabled the usage of 4D modeling during the construction phase. Therefore, the difficulties reported were identified as an opportunity to map deficiencies in the BIM model in order to define parameters for the new project proposals and to automate the process of receiving the model and checking for inconsistencies or lack of information.Implications for Research and Practice: The case study is an example that BIM as a technological tool is not able to promote an integrated design and construction interface by itself. It is necessary to integrate BIM as an integrated process with structured management methods and tools. From our perspective, we understand that contracts should change, including construction stakeholders in the very beginning of the design process fostering collaboration across stakeholders such as designers, design and construction managers, suppliers, and subcontractors, thereby achieving a higher level of improvement potentially carried on by the new technologies allied to management practices. With regard to the nature of this article, it is important to make it clear that the results from this study were based on the Brazilian construction industry only.Limitations: The research is a single-case study; therefore, the findings cannot be generalized. Most of the data were dependent on the interviewees’ self-reported perceptions. We suggest new studies should be conducted with other construction companies in the Brazilian context, comparing companies with different organizational structures and sizes and other types of projects.

In recent years, Brazilian government issued a federal decree establishing the National Dissemination Strategy for Building Information Modelling (BIM) with the expectation that BIM will be disseminated in public works by 2028. In addition to this, the Brazilian Association of Technical Standards (ABNT) has set up a committee to generate and disseminate standardization involving the various aspects of BIM implementation. In this scenario, the objective of this paper is to investigate the BIM implementation process in a Brazilian government infrastructure studied company, and to understand how the Design as well the Consultant Firms are facing the new demands about BIM. An exploratory research through qualitative and quantitative approaches was carried out by a case study. The qualitative approach was based on a set of interviews applied with Technical Professionals and the company´s board that work at the studied company. The quantitative approach was held through an online survey questionnaire applied to the designer´s base that work with the studied company. The analysis was also based on five different guides: BIM Project Execution Planning Guide, RICS Guide, CBIC Guide, EUBIM Handbook and European Construction Sector Observatory. As a result, the paper aims to deliver a set of practical recommendations in order to help the studied company define the demands for their designer´s base so that bidding occur in the best possible way, and also to better its BIM implementation process.

Nos últimos 20 anos, o setor da construção civil no Brasil evoluiu significativamente em resposta ao crescimento da competitividade no mercado. Entretanto, nesse processo de evolução ainda têm sido encontradas barreiras culturais e organizacionais, e, sobretudo, dificuldades nos esforços voltados à qualidade nos canteiros de obras. Aliada a este quadro, a falta de integração entre as atividades de projetar e construir provoca uma série de desperdícios, patologias, retrabalhos e alterações improvisadas decorrentes de projetos não compatibilizados, ora por ausência de detalhes nos projetos, ora por decisões tomadas por pessoas não capacitadas em momentos inadequados. O presente trabalho tem como objetivo geral discutir a implementação do método da preparação da execução de obras (PEO) a fim de melhorar a qualidade na interface projeto-execução de obras. O método de pesquisa adotado para o desenvolvimento deste trabalho é classificado como qualitativo e foi realizada por meio de pesquisa-ação. Os resultados obtidos com a realização da pesquisa comprovaram a eficácia do método da PEO e a sua viabilidade na melhoria da gestão da interface projeto-execução de obras, em empresas de incorporação e construção de edifícios.
