North end of Hai Van Pass tunnel blasted

Date: April 21, 2001

THUA THIEN-HUE - The northern end of the new tunnel through the Hai Van Pass in central Viet Nam look shape yesterday, with construction contractors blasting open the tunnel's mouth.

Following the detonation, 200 Vietnamese workers and Japanese experts from the joint venture between Cienco 6 (Construction Engineering Corp No.6) and Japan's Hazama will start excavation work under the pass.

Hai Van Pass is a crucial stretch of National Highway No. I A that links Thua Thicn-Hue Province with Da Nang.
Under the north tunnel contract (known as Package 1A), the Viet Nam-Japan joint venture will build a 3,365m long, 80sq.m main tunnel, and a 3,365m long 15sq.m evacuation tunnel.

Also included in the work are seven cross-passageways, a 138m long electrostatic precipitator, a 1,565m long ventilation shaft and an 85m approach.

"Young Vietnamese engineers are working very well and we hope to transfer our advanced tunnel technology to the Vietnamese staff in a short time," said Masashi Kuroda, chief of Package 1 A construction.

The Cienco 6-Hazama joint venture started preliminary work on August 26 last year, after Prime Minister Phan Van Khai oversaw a ground-breaking ceremony.

The Hai Van Pass Tunnel Project requires investment of US$251 million, 85 per cent of which will come from the Japanese Government's Official Development Assistance (ODA) loans, provided through the Japan Bank for International Cooperation (JB1C).

The tunnel project consist seven packages: tunnel civil work (packages 1A and 1B); access road and bridges (packages 2A and 2B) electrical works; mechanical works; a 110V/220V substation and transmission lines; maintenance vehicles; and resettlement infrastructure.

A joint venture between Red River Corp and RoK firm Dong Ah is working at the southern end of the tunnel (Package 1B). The mouth there is scheduled to be blasted in June of this year. - VNS
