Preserving Cripta Gaudí with Leica RTC360 Scanner

Capturing History: 3D Documentation of "La Cripta Gaudí"

Leica CPEC and Generalitat de Catalunya Collaborate to preserve Cripta Gaudí with RTC360 Scanner

Cripta Gaudí, an architectural gem designed by Antoni Gaudí and declared a UNESCO World Heritage Site, stands as a significant cultural legacy in Catalonia. To ensure its preservation and provide an accurate and up-to-date documentation of the monument, the Department de Cultura of the Generalitat de Catalunya embarked on an ambitious scanning project using cutting-edge technology provided by Leica Geosystems CPEC.

Objectives

Comprehensive documentation of the monument: The primary objective of the project was to create a complete and detailed graphic record of the Gaudí Crypt. This documentation would serve as a basis for its conservation, dissemination, and as a starting point for future restoration and study projects.

Solution

Implementation of the RTC360: The Architectural Heritage Service, with its specialized technicians in 3D documentation, has the Leica Geosystems RTC360 laser scanner for its ability to capture high-definition data quickly and efficiently. The RTC360 allowed for the documentation of the entire monument, including hard-to-reach areas, without interrupting the dynamics of visits to the site.

High definition and speed: The RTC360 proved to be an indispensable tool due to its capability to capture high-definition data at great speed.
Minimal impact: The technology enabled 200 positioning setups without affecting the monument’s operations, ensuring the continuity of daily activities and visits at the Gaudí Crypt. It is also worth noting that this technology captures data in a harmless manner, without coming into contact with the surfaces of the elements.

Equipment used

To achieve these objectives, Lluís González, the technician responsible for three-dimensional surveying at the Architectural Heritage Service of the Department of Culture of the Generalitat de Catalunya, who was in charge of the project, used state-of-the-art equipment from Leica Geosystems:

Leica RTC360: The RTC360 is a high-definition laser scanner that offers precision, speed, and efficiency in capturing 3D data, with minimal impact on the work environment. This device stood out for its ability to operate in hard-to-reach areas and its compatibility with other 3D documentation systems used by the Architectural Heritage Service.

Benefits

Precise 3D model: The implementation of this solution resulted in the creation of an extremely accurate 3D model of the building, invaluable for future restorations and the conservation of the monument.
Improved collaboration and planning: The level of detail and accuracy of the captured data enhanced communication and planning among different teams.
Management and maintenance tool: The digital documentation obtained became a powerful tool for the long-term management and maintenance of the building.
Dissemination and accessibility: The information will serve as a basis for creating models that will improve the dissemination of the monument’s characteristics among different audiences, from primary school students to university students and the general public.
Accessibility for specialists: The high-resolution 3D model will facilitate the study of the monument by various technical specialists.

Conclusion

This scanning project with the Leica RTC360 not only met its initial objectives but also set a new standard in the documentation and preservation of historical monuments. The use of technology developed by Leica Geosystems by the Architectural Heritage Service of the Department of Culture of the Generalitat de Catalunya allowed the creation of a detailed and accurate 3D model, ensuring the preservation and dissemination of this World Heritage site for future generations.
