Location: Church of San Paolo Pisa, Italy
- 3D Point Cloud (Intensity map and grey scale)
- 2D CAD drawings, scale 1:20
- Orthophoto, scale 1:20
- Crack System Mapping
The survey of the Church of San Paolo in Pisa (925) was commissioned for the restoration project, documentation, and monitoring of the static condition of the structural walls in masonry.
The graphical representation of 2D plans, sections, and elevations at scale 1:20 enabled the definition and drawing of the stone works, including the millimetric gap between each stone. This meticulous detailing is crucial for restoration planning.
High Resolution Orthophotos were essential to identify a complex crossing cracks system compromising the church’s stability. This visual documentation played a pivotal role in assessing the extent of structural issues, providing valuable insights for the restoration project.
In summary, the survey not only documented the architectural details but also contributed vital information for the restoration and preservation of the Church of San Paolo in Pisa, ensuring a comprehensive understanding of its structural condition.
3D Laser Scanning, The Technology to Achieve The Necessary Accuracy
- Our Surveying team utilises cutting-edge 3D laser scanners with a maximum accuracy error of +/-1 mm. The scanners operate at a speed of 1,000,000 points per second, making them the ideal tool for efficiently acquiring measured point clouds.
- The expansive range and high resolution of our laser scanners enable precise measurement of the internal elevation of the Church, defining the shape of each stone with remarkable accuracy due to the high density of measured 3D points.
- The digital survey conducted using Laser Scanning technology requires no physical contact with the historic surface and stones of the church, ensuring the safety and accuracy necessary for surveying fragile historical features.
- Post-processing the scan data yields a comprehensive 3D point cloud reproduction of the real church, serving as the foundation for extracting 3D models and detailed 2D drawings through software interpretation, such as AutoCAD or Revit.
- Combining this 3D information with detailed drawings at scale 1:20 and High Resolution Orthophotos, we created an accurate map revealing a complex crack system running through the main structural walls in the masonry of the monumental Church of San Paolo, a discovery crucial for understanding and addressing stability issues.
- The Laser Scanning Survey, along with its deliverables, emerged as an essential tool in defining the appropriate structural intervention and forming the basis for the comprehensive restoration project of the Church of San Paolo. The precision afforded by 3D laser scanning technology played a pivotal role in ensuring the accuracy and success of the restoration endeavour.
