RESUMO:

The systematic monitoring and control of the construction progress are essential activities for an efficient construction management process as planned. However, the most common practices for progress monitoring are based on individual observations, manual collection and extraction of data, and rely on text-based documentation. In order to improve such aspects, studies highlight applications of visual data technologies, as solutions that enable a faster, reliable and transparent progress monitoring process. Nevertheless, despite this new approach, little has yet been done for the systematic integration of the technologies of 3D mapping by Unmanned Aerial Vehicle (UAV) and Building Information Modeling (BIM) for visual progress monitoring, into construction management systems routine. This study aims to propose, implement and evaluate a method for a systematic visual progress monitoring integrated into the production planning and control process, supported by 4D BIM and photogrammetric 3D mappings using UAS imagery. The study was developed based on Design Science Research strategy, including the following research steps: (1) Awareness: literature review, elaboration of the conceptual framework and understanding of the research problem; (2) Artifact suggestion: testing of tools and processes related to the proposed method, from an exploratory practical study in a construction site, resulting in the drafting of the preliminary proposal of the artifact; (3) Artifact development: structuring and refinement of the scope of the proposed method, from its implementation in two case studies in construction sites; (4) Evaluation: evaluation of the method and the results obtained in its implementations, from the definition of research constructs and variables; and (5) Conclusion: formalization of the final structure of the method and presentation of guidelines for its implementation. The case studies to implement and evaluate the proposed method took place in construction projects located in the metropolitan region of Salvador – BA. The evaluation of the method and of its implementation was developed from the following constructs: (a) Compliance with the planned goals; (b) Impact on the construction progress deviations; (c) Transparency; (d) Collaboration; (e) Usefulness of the proposed method; and (f) Easiness of adoption and integration of the method. Those constructs were evaluated based on the results of data collected, products developed during the implementations, structured interviews, feedback of the management teams of the construction projects, and participant observation of the researcher. The main findings indicated that the proposed method implementation enables an improved integration of progress analysis and decision-making, the improvement of progress deviations’ identification and its main causes, and allowed for better compliance with the planned goals and increased transparency and collaboration in production control. The main contributions of this work are the development and support for a systematic integration of the proposed technologies into the construction planning and control routine, and a better understanding of the impact and added value of the flow of information provided by the adoption of such technologies for construction progress monitoring.
