On the recent trip to France by General Secretary of the Communist Party of Vietnam Nguyen Phu Trong, T&T Group signed memorandum of understanding on construction of two big projects in Vietnam with Bouygues Construction.
In particular, one is the metro connecting Hanoi centre with Son Tay town with the estimated length of 31.1km at the estimated cost of up to $1.7 billion. The other project is the drastic transformation of Hang Day stadium in the centre of Hanoi, which will cost $307 million.
Do Quang Hien, Chairman of T&T Group told local press that the Hang Day stadium has been severely deteriorated and a transformation is exactly what is required. This stadium can totally be redeveloped into a more contemporary and world class stadium with a great architecture, especially with the cooperation of Bouygues.
“It will not simply a football field but will include so many other function areas," he said, adding that the stadium would contain four basements, the second level being the football field with the rooftop grandstand that can contain over 20,000 people," Hien was quoted as saying.
"Additionally, the upper levels surrounding the rooftop grandstand are designed to become offices, shopping centre etc. creating a very modern stadium. The old state of the stadium will also be extended towards Cat Linh street, the land of Hanoi Authority of Planning and Investment,” said Hien.
