This article presents a comprehensive case study of geodetic monitoring for building deformations during the construction of an adjacent shelter at Educational Complex No. 183 «Fortuna». The study focuses on the lyceum building, located just 15.5 meters from the excavation boundary, where 15 reflective deformation marks were installed on the façade and monitored using a high-precision Alpha-GEO X (2") total station. The free station method, combined with inverse linear-angular notching from an external geodetic network, ensured displacement measurements with an accuracy of ±1–2 mm. Monitoring was conducted over four months (November 2023–March 2024), with 12 measurement cycles.
Results revealed minor deformations within safe thresholds: vertical displacements (Z-axis) peaked at +3 mm, while horizontal shifts ranged from -3 mm to +3 mm (X/Y-axes). Critical points (e.g., N-3, B-6) showed maximal but non-progressive movements, confirming localized soil stress redistribution without structural risks. The study validates the efficacy of robotic total stations for real-time deformation control in urban construction and underscores the importance of rigorous monitoring programs to safeguard adjacent structures. Key recommendations include maintaining 10-day monitoring intervals and immediate alerts for displacements exceeding 5 mm. This methodology offers a replicable framework for similar high-risk construction projects.
