(Photo: Nutthawat Wichieanbut)A year after its new headquarters tower crumpled during an earthquake, the State Audit Office (SAO) has outlined four critical structural and construction failures that led to the collapse. The SAO said findings from multiple investigations pointed to serious flaws in design, materials and construction practices. Concrete samples taken from shear walls were found to be below required strength standards. Reinforcement steel at critical joints, particularly between link beams and shear walls, was embedded at insufficient depth, weakening the structure. : The National Anti-Corruption Commission (NACC) is examining the possible involvement of state officials, with the SAO providing requested documents.
