HA NOI (VNS) — The Ministry of Construction on Monday urged the Government to suspend construction of the Da Dang-Da Chomo hydropower plant in Lam Dong province and investigate the cause of the tunnel's recent collapse.
The tunnel collapsed last week, trapping 12 workers inside for 81 hours. They were rescued and taken to Lam Dong General Hospital for treatment on Friday. All workers recovered and have been discharged.
Deputy Minister of Construction Le Quang Hung said the tunnel might have been poorly constructed and unable to bear pressure from the land above it. It should be investigated to prevent more incidents from occurring, he said.
The investor and contractors should take the blame for the incident, because they didn't study the geological conditions carefully enough or design the tunnel correctly, Hung said.
However, the ministry would review construction progress to find out who is at fault, he said.
Hung said the Government would cite regulations in two decrees on the construction of hydropower plants to investigate transgressions committed during construction. Decree 209 would be used for work completed before 2013, and Decree 15 would be used from 2013 onwards.
In Decree 209, Government agencies merely issued rules to manage the construction of government building projects. They trust the investors and contractors to follow those rules.
In Decree 15, investors and contractors must submit technical reports to the Government so it can monitor their progress and the buildings' quality.
Under the second decree, the Ministry of Industry and Trade is responsible for testing designs and monitoring the construction of hydropower plants. — VNS
