Striking fact about the building that collapsed in Bahçelievler: Three extra floors were added

Sinan Türkkan, President of the Earthquake Strengthening Association (DEGÜDER), said regarding the 7-story building that partially collapsed in Bahçelievler, "If you add 3 more floors to a building that is already struggling to carry itself, from an engineering perspective, the result is inevitable."

Reminding of the earthquake risk in Istanbul, Türkkan stated, "If we consider Istanbul as a whole, we can say that there are quite a lot of such buildings. We must make a decision as soon as possible and absolutely overhaul and make earthquake-resistant those buildings that were built before 2000, whose concrete was mixed by hand, which have plain reinforcement bars, and which did not receive the necessary engineering services."

Emphasizing that there was uncontrolled construction in Istanbul between 1970 and 1990 along with population growth, Türkkan said, "This building was built in 1980. This building was likely constructed after excavation without any precautions against water—because it is said there is corrosion in the building—and without any insulation measures. I am not even mentioning the regulations. In terms of construction conditions, it was built under quite primitive conditions. You then add 3 more floors to this building in 1994. If you add 3 more floors to a building that is already struggling to carry itself, from an engineering perspective, the result is inevitable."
