HA NOI — The Tin Nghia Trade and Construction Co Ltd was named and shamed after extremely poor quality work on the Dieu Ga Reservoir was discovered in Binh Thanh Dong Commune, in the central province of Quang Ngai, earlier in the week.
Nguyen Thuy, chairman of the commune's People's Council, said that leaders of the commune uncovered the shoddy work when examining the construction site on Monday.
He said that workers at the construction site of the dam had cut corners and used red soil and clay mixed with cement for the work, which was 90 per cent finished.
"No one mixes cement with this kind of soil to concrete a dam. They have to mix cement with gravel and sand, to ensure the quality of the work," Thuy said.
After taking the sample of the mixture for testing, it was found the mixture contained only 30 per cent of cement with the rest comprised of red soil, clay and waste sand, he said.
Initial investigations revealed that more than 40 metres of the breakwater had been built using the substandard mixture.
"It was total violation of construction quality controls," said Le Van Lac, a staff member at the provincial Irrigation Work Unit and Flood Prevention and Control unit.
Le The Thanh, deputy director of the Management Board of Investment Projects under the provincial Department of Agriculture and Rural Development, said the Tin Nghia Trade and Construction Co Ltd would have to remove the 40 metre-section of the dam and rebuild it.
However, Thuy said leaders and residents of the commune were also worried about the completed part of the dam.
"How are we to know if the construction was good enough or not? When the flood season comes, a badly constructed dam could break and leave us exposed to extreme risk," he said.
He said the commune authority had sent a document to Binh Son District's People's Committee to propose further investigation of the quality of the dam's construction. — VNS
