Proposição de sistema automatizado de benchmarking de indicadores geométricos para projetos arquitetônicos residenciais multifamiliares baseados em bim

Abstract

The construction industry plays a fundamental role in economic growth, standing out for its capacity to generate employment, drive urban development, and integrate with various productive chains. However, this sector faces significant challenges, such as the need for technological adaptation, increasing regulatory demands, intense competition, and, above all, difficulties related to project performance management and evaluation, given its complexity and fragmentation. In this context, benchmarking emerges as a relevant strategy to promote continuous improvement and competitiveness by enabling structured comparisons between projects based on standardized indicators. Therefore, this study aimed to develop an automated benchmarking system capable of generating and organizing reference values extracted from BIM models, which can be used by companies to compare the performance of their projects against sectoral parameters and assist designers in monitoring indicators during the design process. These values allow companies to compare the performance of their projects with industry benchmarks and enable designers to monitor indicators throughout the design phase. The research adopted the Design Science Research (DSR) methodological approach, involving the creation of an artifact composed of automated routines for extracting geometric performance indicators. The indicators were defined based on the literature and a technical document from Inovacon. The tool was developed by integrating Revit software with visual programming, enabling automatic data extraction and export of results to Excel spreadsheets. The system was validated through application in twenty multifamily residential projects in the state of Ceará, initially received in DWG format and later modeled in BIM. The extracted indicators enabled the organization of a database that supports benchmarking between projects according to classification ranges. As a result, an automated tool was obtained, capable of reducing analysis time and standardizing indicator calculations, applicable at different project stages: feasibility, development, and completion, continuously feeding the database. From a practical perspective, the study contributes by providing a system that supports companies and designers in project comparison and monitoring. From a theoretical perspective, it advances the integration between benchmarking, geometric indicators, and BIM automation. It is concluded that the application of automated benchmarking supported by BIM tools represents a relevant advancement in project management, promoting greater efficiency, technical grounding, and continuous improvement in the construction sector. The study’s limitations include the scope restricted to geometric indicators, the database composed solely of projects from a specific region (Ceará), and dependence on the use of Revit and Dynamo tools for executing the routines.
