Premchai Karnasuta, the president of Italian-Thai Development Co, the main Thai contractor for the building project, as well as designers and engineers were among 17 charged with the felony of professional negligence causing death, Bangkok deputy police chief Noppasin Poonsawat said.
The accused have publicly denied wrongdoing.
The search for victims’ remains was officially ended on Tuesday, though efforts to identify body parts through their DNA will continue.
Noppasin said at a news conference that evidence and testimony from experts suggested the building plan did not meet standards and codes. The Bangkok Post newspaper said police had also determined the project showed “structural flaws in the core lift shaft and substandard concrete and steel”.
