HAI PHONG (VNS) — Deputy Minister of Transport Nguyen Van Cong gave Civil Engineering Construction Corporation No 4 the green light to try using sea sand instead of river sand when building the Tan Vu – Lach Huyen Sea Bridge in Hai Phong.
The move came after the company had trouble collecting the 50,000 cubic metres of river sand it needed to build the roadbed of the bridge's approach before March 30, as scheduled.
Using sea sand from Hai Nam and Dinh Vu mines, which were close to the construction site, would also help reduce time and transport expenses, said Hoang Van Dao, the company's deputy director.
The project would first need to test the sea sand, to see if it could be used successfully instead of river sand. If it worked, it could be used more widely in the construction sector, he said.
However, sea sand gave way easier than river sand when vehicles drove over it, said Deputy Minister Cong. He told the company to prepare an alternative, in case its plan failed.
Civil Engineering Construction Corporation No. 4 needed to send its two detailed plans to authorised agencies by March 28, Cong said.
Tan Vu – Lach Huyen is the country's longest sea bridge. Construction started last February, with a completion date set for 2017.
The 15.6km sea bridge is a key national project that will connect eastern areas of the city to Lach Huyen Port, Dinh Vu Industrial Park and the Ha Noi – Hai Phong Expressway.
The construction of the bridge is being funded with more than VND10 trillion (US$466 million) in Official Development Assistance from Japan and VND1.8 trillion ($83.8 million) from the Vietnamese Government. — VNS
