Track progress over time, update deviation maps, and compare results with baseline data. Guarantee alignment of building models with designs by addressing deviations early on. This systematic process guarantees error correction, project alignment, and desired outcomes. Successful deviation analysis hinges on precision and adherence to the step-by-step process outlined.

Data Collection

Data collection for building deviation analysis is a critical initial phase that involves systematically gathering as-is BIM data from a variety of sources, including laser scanning, photogrammetry, and existing drawings. This step is essential for obtaining detailed information on building components, geometry, and spatial relationships. Various methods such as point cloud data acquisition, 3D laser scanning, and photogrammetric surveys are employed to capture accurate building information.
