Automation of pre-assembly BIM, Dynamo and Augmented Reality to optimize execution time of metal formwork for vertical elements in multi-family

Abstract

In multi-family housing projects in Metropolitan Lima, vertical metal formwork is a critical activity that often causes schedule delays. Therefore, this research evaluates the automation of pre-assembly using Building Information Modeling (BIM), Dynamo, and Augmented Reality (AR). To reduce execution times, a methodology was applied that integrates automated modeling processes in Revit and Dynamo, as well as construction simulation in Navisworks, to analyze the performance and productivity of the metal formwork. Augmented Reality was used as a real-time visualization tool to guide on-site assembly. Finally, the proposal was validated through expert judgment in the construction sector, ensuring its relevance and applicability. The results obtained show a 79% improvement in performance, a 70% reduction in labor costs, and a 41% increase in the Schedule Performance Index (SPI). These findings demonstrate that automating pre-assembly using BIM, Dynamo, and AR significantly optimizes the execution time of vertical metal formwork, making it an innovative, efficient, and applicable solution for improving productivity and performance on construction sites.
