Idris Karataş, a civil engineer working as a contractor in Malkar, Tekirdag, asked the Directorate of Environment, Urbanization and Climate Change in March last year before starting the construction of a house consisting of 3 blocks with 27 apartments to control the materials to be used in the construction. After examining the concrete samples, specialists from a licensed laboratory company reported that it was suitable for use. After receiving the report, Karatash applied to the municipality, obtained the necessary permits and began construction. After completing the rough construction, the engineer had to stop the construction work because he discovered that the concrete had developed serious cracks and deformations.
Idris Karataş asked Istanbul Technical University (ITU) to conduct an independent examination of the construction materials. Prof. Dr. Mustafa Gençoğlu from the Civil Engineering Department of the Faculty of Civil Engineering traveled to Malkara and examined the structure. In his report, Gençoğlu favored the demolition of the structure because the quality of the concrete did not meet the stated requirements.
The engineer filed a lawsuit against the laboratory that issued the positive report on the concrete he used, the concrete plant that produced the concrete and the company that supervised the construction. The prosecutor's office is still investigating, however, the laboratory that issued the "reliable" conclusion has already been closed, and a ban on such activities for 3 years has been imposed on its owners and responsible persons. By the way, the contracting company where Idris Karataş worked also paid a fine of 1 million 58 thousand liras to the municipality.
