Application of bim and augmented reality in a hydropower plant modernization

This paper presents results of case study São SimãoHydropower Plant, the development and testing of an application that applies augmented reality to display BIM information over the real infrastructure of hydropower plant existing areas. The application aims to assist users in identifying interferences between future AEC projects and current electrical, mechanical and civil infrastructure. The work focused in evaluating BIM data and sources to face data integration issues with an Augmented Reality development platform and in combining multiple tracking strategies to achieve assertive positioning of objects in the real world. It took several iterations to meet precision goals and establish a logical sequence for the algorithm. This tool intends to reduce rework and losses in construction sites by sharing project information and assisting decision making process.
