Can Tho Bridge Probe Reveals Disturbing Facts

It’s almost certain that weakness in the supporting pylons and substandard bracing and scaffolding were responsible for the collapse of Can Tho Bridge, according to Sai Gon Giai Phong sources.

Investigators have found that Pylon No. 14 was at around 70 percent declination before it came crashing down, and the adjacent pylons were also about to sink.

In fact, the Japanese contractors had not made full and separate geological surveys of the Mekong Delta, where the alluvial earth is soft and weak in general.

Instead, they extrapolated the results of their survey for Pylon No. 13 to other pylons without checking whether conditions were the same.

Investigators are still checking the depths of these other pylons to determine who knew what and who was responsible.

Notably, the scaffolding did not meet technical requirements and had been used to build a high-speed transport network in Bangkok, then reused by a Japanese company.

Just as seriously, the contractors had neither checked the scaffolding nor the foundations, a strange thing to forget in delicate terrain like the Mekong Delta.

According to several sources, the supervising consultant Nippon Koei had given a warning beforehand and demanded a test; however, the tragedy still happened.
