Abstract
Buildings are often complex and hindered by identifying and measuring deformation in both the building itself and its elements. However, we have the assistance of 3D laser scanning technology which allows us to collect geometric data. Scanners are particularly effective for measuring high and hard-to-reach locations. This paper focuses on the measuring and modeling of roof drainage installations, which are usually placed at elevated heights, making it impossible to measure using traditional methods. Rain gutters need constant monitoring in order to fulfill their function and ensure proper drainage of rainwater. Laser scanning produces a point cloud which can be converted in a 3D model using software such as Leica Cyclone, AutoCad and ReCap. This study demonstrates the successful utilization of laser scanning in identifying geometric features and deformations in building installations.
