There are those projects that we are happy to work on because we have a deep feeling of responsibility towards our heritage. This is the case with this small jewel of a protestant church and belfry also, which bears the marks of Károly Koós, who designed the latest significant transformation of the church.
LIDAR Scanning
During the survey, we scanned both the protestant church and the belfry with a static LIDAR scanner for maximum precision. The registered color pointcloud had a margin of error of maximum 5 mm. Our biggest challenge was scanning the intricate wooden load-bearing elements of the church roof and the belfry. To achieve this we needed to find the appropriate angles from which all relevant details were visible, this is why we chose to use our Leica BLK360 for this task, because of its small form factor it can easily fit in smaller areas.
BIM Modeling
During the BIM (Building Information Management) modeling part of the project we strived to keep both the horizontal and the vertical margin of error between reality and the digital twin model below 5 cm, which is an industry standard for historical buildings, although it might be hard to achieve with other methods of survey, and especially hard to verify it’s accuracy.
We paid special attention to traditional details of the church such as the coffered, painted ceiling and the small details that bear the mark of Kós Károly’s design.
A special request of our client was to represent water damage in the model, which we managed to do.
Architectural Drawings
Due to being represented in the BIM model, the water damages, although they might appear as fills in the drawings, they are actually resulting from the BIM model.
Conclusion
In conclusion, our involvement in this project was driven by a deep sense of responsibility toward preserving our heritage. To achieve this, we meticulously conducted LIDAR scanning, ensuring precision with a margin of error of just 5 mm. Furthermore, our Leica BLK360 played a crucial role in capturing intricate details.
In the realm of BIM modeling, we maintained a 5 cm margin of error, aligning with industry standards for historical buildings. We paid special attention to preserving traditional details.
Moreover, we successfully incorporated representations of water damage into the model, enhancing its accuracy and value. Therefore, our comprehensive approach ensured the faithful preservation and representation of this historic structure.
