# Structural safety incidents in Istanbul > Live situation record from CLSTR: https://clstr.news/situations/structural-safety-incidents-in-istanbul > Updated: 2026-10-27T02:14:00.000Z. Sources: 9. Developments: 2. Recent incidents in Istanbul have necessitated the evacuation of residential buildings due to structural concerns. In the Eyüpsultan district, a five-story residential building constructed in 1972 was evacuated and sealed after residents reported noises coming from its structural columns. A preliminary inspection identified a crack in one of the columns. Authorities are awaiting technical reports and core samples to determine the final safety status of the structure. In the Bahçelievler district, specifically in the Siyavuşpaşa neighborhood on Çavuşpaşa Avenue, the collapse of a retaining wall at a construction site undergoing foundation excavation caused approximately 10 centimeters of ground subsidence. The incident, occurring around 03:00, affected two adjacent residential buildings—one six stories and one seven stories tall. Residents reported hearing cracking sounds and feeling vibrations, prompting many to flee in panic. Local observations noted structural damage such as tilted doors and cracks. As a precautionary measure, emergency services including police, firefighters, and municipal officers evacuated a total of 20 apartments. Authorities have established security perimeters while technical teams conduct investigations to determine the cause of the wall failure and assess the structural integrity of the buildings. ## Timeline ### 2026-10-27: Bahçelievler construction collapse leads to building evacuations A retaining wall collapse at a construction site in Istanbul's Bahçelievler district caused ground subsidence, leading to the precautionary evacuation of 20 apartments in two adjacent buildings. 8 sources. https://clstr.news/cluster/istanbul-buildings-evacuated-after-construction-wall-collapse ### 2026-10-23: Eyüpsultan building evacuated after structural cracks detected A 5-story building in Istanbul's Eyüpsultan district was evacuated and sealed after cracks were discovered in a structural column. 2 sources. https://clstr.news/cluster/eypsultan-building-evacuated-after-structural-cracks-detected --- Cite as: Structural safety incidents in Istanbul.
