Hanoi (VNS / VNA) Hanoithe population of, in July 2021, reached over 8 million, increasing by almost 200,000 people per year on average.

The capital continues to grow and new solutions are needed to manage this expansion. One idea being considered is to make more use of underground spaces.

According to figures from the city’s traffic police, there are around 7.6 million Vehicles registered in Hanoi, excluding 1.2 million vehicles from other cities and provinces that regularly visit the city.

The growth rate of vehicle spaces has not kept pace with this increase in the number of vehicles, leading to overloading of urban infrastructure, traffic jams and air pollution.

One solution is to build an underground circulation system or even entire underground urban areas.

Since 1996, a number of shopping malls and hotels in Hanoi have built two to four levels of basements.

The city has also built a number of underground intersections such as the underground tunnels of Kim Lien, Thanh Xuan and Trung Hoa, as well as underground technical infrastructure systems in drainage, electricity and water supply pipes.

By the end of 2020, a private housing project in the Ba Dinh district covering an area of ​​more than 300 m² will include up to four basements.

The vice president of the architect of the Vietnamese Association of Urban Development and Planning, Dr Dao Ngoc Nghiem, told the Kinh Te & Do Thi (Economy and Urban Affairs) newspaper that it was time for space underground becomes an important consideration in the urban development strategy.

Dr Pham Hung Cuong, former head of architecture and planning at Hanoi Construction University, said: “The development of underground space includes two aspects of public space and the public transport system. . If done right, it will solve many urban problems.

“However, Hanoi is only in the early stages of developing these two aspects. If there was no planning soon, there would be many difficulties. The first problem will be the basements of the apartment buildings. high rise that were built, ”Cuong said.

“At that point, the underground traffic lanes will have to circulate, which will be costly and controversial. This is the case with the C9 metro station near Hoan Kiem Lake, “he said.

Therefore, Hanoi needs to focus on underground planning as early as possible, to develop a plan that aligns with the whole city.

Underground space planning is only mentioned, but not developed, in existing regulations, such as the Hanoi Building Plan to 2030, with a vision for 2050, approved by the Prime Minister in Decision No.1259 / QD TTg, and Hanoi’s transport planning for 2030 and a vision for 2050 approved by the Prime Minister in 2016.

In addition, there are no recommendations and research results for land use plans for the construction of underground spaces, according to the director of Hanoi Urban Planning and Architecture Department Nguyen Truc Anh. .

Adjustments in construction planning in Hanoi are needed, with proposals on the locations, areas and extent of the city’s main underground spaces, as well as planning for how to maximize land and space. urban, he said.

The Hanoi Construction Planning Institute has just completed an underground space project for the city and submitted it to the Municipal People’s Committee for approval in the near future.

According to the plan, underground traffic routes are mainly developed at intersections, squares, train stations and metro stations.

In particular, 79 underground public car parks will be built in nine districts of the city center. The total construction will cover an area of ​​107 hectares.

The parking areas will include basements of three to five levels, in combination with shopping and service centers.

The underground stations of the urban rail network will be the core of future underground public spaces within a radius of 500 m.

There will be 65 underground public spaces with a total area of ​​2,171 hectares./.
