As part of this project, the existing structure of a high-rise building was meticulously surveyed and transformed into a digital model. The objective was to create a precise foundation for future planning within the framework of Building Information Modeling (BIM). The survey was deliberately conducted using traditional measuring tools such as a DISTO laser measurer and a folding rule. This manual approach enabled a particularly detailed capture and a comprehensive understanding of the building’s interior. Direct interaction with the structural fabric and the spatial layout allowed for the consideration of aspects that might have been overlooked when relying exclusively on modern laser scanners. These include, among other things, structural peculiarities, material properties, and irregular or concealed features. During the survey, all essential details of the high-rise building were documented, including load-bearing elements and spatial geometries. The collected data was subsequently converted into digital plans and a three-dimensional model. This model not only provides an accurate representation of the existing structure but also serves as a foundation for future BIM-based planning and construction processes. The conscious decision to forgo exclusively automated methods highlights the added value of manual engagement with the building. The project demonstrates how traditional working methods and digital technologies can be effectively combined to achieve not only technical precision but also a profound understanding of a building’s specific characteristics. The completed digital model now serves as a robust basis for renovation, remodeling, or expansion projects. It supports architects, engineers, and developers in efficient planning and the seamless integration of modern building technologies into the existing structure. This project proves that the transition from traditional surveying techniques to digital planning methods is not only feasible but also highly effective when both approaches are combined.
