Asahi Kasei Corp. revealed Tuesday that piling data had been falsified in at least more than 10 percent of the projects worked on by a subsidiary over the past decade.
Amid a deepening data falsification scandal engulfing Asahi Kasei Construction Materials Corp., 61 workers were found to have fabricated data on piling work in 360 out of the 3,052 projects handled by the company.
The revelation may raise questions about whether management properly oversaw the handling of the data as public concerns are growing about the safety of buildings in general.
