BEIJING (Reuters) - A Chinese court has jailed two officials after they let a blind contractor build a bridge which collapsed during construction and injured 12 people, the official Xinhua news agency said Monday.

Huang Wenge, township head of Bujia in the southeastern province of Jiangxi, and colleague Xia Jianzhong were sentenced to 18 months and one year in jail, respectively, for not stopping the project, Xinhua said.

“Huang Wenge and Xia Jianzhong, who were in charge of road management and supervision, did not ask the contractors to provide certificates guaranteeing their proficiency,” it said, citing the court ruling.

“When they knew the bridge was being built by a blind contractor, they did not stop it,” it said, adding the contractor had changed the blueprint without getting a professional to look at the design.

“After the blind contractor changed the blueprint, he carried out the work only using a roughly drawn draft of the plan, which caused the bridge to collapse,” the report said.

Xinhua did not explain how the contractor was able to run the project considering his inability to see.
