Abstract
The study addresses the issue of monitoring unfinished or repurposed structures, which often remain outside systematic control yet may pose risks to surrounding infrastructure. The object of observation was the Rivne Regional Youth Sports School, whose construction was never completed and was later repurposed as a marketplace. The primary aim of the research was to detect deformations of the roof and load-bearing structures. The methodology was based on the use of terrestrial laser scanning, which enables high-precision creation of three-dimensional models of complex objects. Measurements were conducted in three cycles. The results showed that between the first and second cycles, displacements ranged from –29 mm to +10 mm, indicating low deformation activity. In contrast, between the second and third cycles, significantly greater displacements were recorded – from –49 mm to +61 mm – suggesting an intensification of deformation processes, likely caused by construction activities. Visualization of vertical displacements confirmed localized zones of roof subsidence and uplift, indicating spatial heterogeneity of the structure. The study presents a case of applying terrestrial laser scanning to monitor structural deformations in a repurposed building. Based on three observation cycles, the research identified spatial displacement patterns and localized zones of risk, contributing to improved safety assessment and planning.
