Improvements in the management of heritage buildings through the use of three-dimensional geometric models

Abstract

Currently, the execution of maintenance, restoration, and conservation processes for built heritage constitutes a fundamental pillar in the preservation of the historical and cultural value of cities worldwide. For this reason, the application of technological advances in the automation and optimization of these processes is becoming increasingly important in the construction sector. Specifically, the integration of Geomatics and BIM (Building Information Modeling) offers considerable advantages for the analysis of buildings and architectural and engineering works. Three-dimensional modeling from point clouds allows for the creation of precise geometric models, achieving high precision by capturing details that would otherwise be impossible, enabling dimensional controls, the generation and obtaining of "as built" plans, among other advantages, which increases efficiency and productivity and reduces the time required to carry out the work. This paper shows the results of applying these technologies to obtain a 3D model in REVIT software from point clouds generated with Unmanned Aerial Flight (UAV) technology of the Julio Grave de Peralta Park roundabout "Parque de las Flores" in the historic center of the city of Holguín.
