Many Cities In Guangdong, Hong Kong And Macau Have Developed An Extra International Warning Line.

In April 2nd, the Nansha River Bridge (Humen second bridge), the main river passage in the core area of Guangdong, Hongkong and Macau, was officially opened to traffic. It is the first super project to be launched after the announcement of the "outline for the development of the bay area of Guangdong, Hong Kong and Macau". It will open up new arteries for interconnection between the bay area of Guangdong, Hong Kong and Macao. At present, transportation infrastructure construction and urban renewal across and around the city are continuing. The planning and development of urban construction in Guangdong, Hongkong and Macau will bring new opportunities for engineering, architecture, urban planning and urban management.

The outline of the development plan for the Great Bay area of Guangdong, Hong Kong and Macau (hereinafter referred to as the "Outline") clearly points out that in the construction of the big bay area of Guangdong, Hongkong and Macau, we should improve the urban agglomeration and the urban development system. The four major cities of Hongkong, Macao, Guangzhou and Shenzhen will serve as the core engine of the regional development, promoting the development of the bay area, and constructing the big bay area suitable for living, industry and tourism. As a result, how to constantly improve the urban planning and construction issues in the 11 cities of Guangdong, Hongkong and Macau is also on the agenda. In March 26th, the Hongkong Trade Development Council led Hongkong's urban construction service delegation to Guangzhou for deep cooperation.

The comprehensive interview was informed that with the development of the big bay area in Guangdong, Hong Kong and Macao, the transportation infrastructure has helped to promote interconnection between cities. The opening of major projects such as the Hong Kong Zhuhai Macao Bridge, the Guangzhou Shenzhen Hong Kong high speed rail and the Nansha bridge has injected momentum into the Da Wan district. At the same time, the emergence of major industries in Tai Wan will bring new demands on urban planning and construction. Among them, the attraction of Guangzhou Shenzhen Science and technology corridor is increasing, and the demand for office buildings, warehouses and other carriers will also rise sharply. How to meet these needs under the limited land supply conditions in the big bay area is a key issue to be considered in the urban planning and construction industry. Therefore, it is also very important to explore new plans for urban renewal and renewal.

As one of the highest population density cities in the world, Hongkong has some successful experiences in the area of network traffic planning and coordinated development of urban construction. At present, there are still differences between Guangdong and Hong Kong enterprises in terms of standards and qualifications. A number of Hongkong construction enterprises representatives also told reporters on twenty-first Century economic report that they hope that with the support of the government, they will cooperate with other cities in the big bay area of Guangdong, Hongkong and Macau to further promote the coordinated development of the city.

The intensity of urban development in the bay area needs to be explored.

Transportation infrastructure is the first condition for optimizing the urban planning and construction in Guangdong, Hongkong and Macau. The outline also points out that the Great Bay area should rely on high-speed rail networks, intercity railways and high-grade highways as the main transportation network and port group and airport group to construct regional economic development belt, and form a network connection pattern among major cities. For example, the opening of the Nansha bridge can further help the formation of the one hour living circle in Tai Wan district. "The transportation infrastructure in Tai Wan is very important, just like a person's meridian. Only when the meridians pass through, can the whole person be revitalized. Ai Yikang, President of China AECOM, made an analogy in an interview with the economic news reporter in twenty-first Century.

In fact, the value of transport infrastructure for the bay area is more than that. From the industry point of view, the significance of infrastructure has gone beyond the scope of physical facilities, and it will also become a part of the city itself. In the other Bay area of the world, Ju Heng, for example, said that the cable car system in San Francisco was only built for the convenience of transportation. "But now it has become part of the city and has become the image and cultural gene of the city."

On the other hand, with the gradual expansion of new industrial clusters in the big bay area of Guangdong, Hong Kong and Macao, the industry will also put forward higher requirements for infrastructure carriers such as offices. Taking the construction of Guangzhou Shenzhen Science and technology innovation corridor as an example, the continuous entry of science and technology enterprises means that the demand for office buildings and warehouses will also be greater. Dead Leung Ban's report on the science and technology industry and property carrier of the bay area of Guangdong, Hong Kong and Macau released in October 2018 predicted that by 2022, the size of Grade A office buildings in typical cities of 4 cities in Guangzhou, Shenzhen, Hongkong and Dongguan will increase from 594 square meters to 1458 square meters.

Apart from the scale expansion, the construction carrier will also change with the industry demand in the big bay area.

Shaofeng, chief executive and director of the Strategic Development Department of Huazhong District, DTZ, told reporters on twenty-first Century economic report that in light of the science and technology corridor, enterprises with light assets are expected to take a relatively large proportion. Enterprises may not have much demand for low-level plants with traditional levels. Instead, according to the change of production mode and storage demand, the warehousing layout system may be transformed into vertical arrangement. "There may even be ten storeys of factory buildings."

All these factors mean that the big bay area of Guangdong, Hong Kong and Macau needs to constantly optimize urban planning and construction. It is worth noting that the supply of land in the bay area is also limited. The Guangdong Provincial Academy of Social Sciences released the report on the construction of the bay area of Guangdong, Hong Kong and Macau (2018), pointing out that the total amount of GDP in the bay area of Guangdong, Hongkong and Macau exceeded one hundred thousand billion yuan in 2017, accounting for 12.57% of the total proportion of the whole country, but the land area in the big bay area is only 0.6% of the whole country.

Meanwhile, in twenty-first Century, the economic report reporters learned from the information that at present, the key cities in the bay area are generally more intensive in land development. For example, the intensity of land development in Shenzhen is over 55%, and the level of development in Dongguan is close to 50%. In Zhuhai and Foshan, it has exceeded 35%, Guangzhou is close to 30%, Hongkong is 24.4%, and the warning line for international urban development is 30%.

Therefore, in addition to making urban planning in advance, exploring the successful mode of urban renewal and upgrading is also crucial. The outline shows that we should give full play to the advantages of many cities and towns in the nine cities of the Pearl River Delta, cultivate a number of attractive towns with distinctive advantages, improve municipal infrastructure and public service facilities, develop characteristic industries, and inherit traditional culture, so as to form an important support for optimizing the regional development pattern. "Promoting urban planning and transformation projects is a major policy direction in the big bay area now. Various cities in the big bay area are introducing some flexible policies to revitalize traditional agricultural land or collective land, and actively transform them, and since last year, cities have made greater efforts." Shao Feng told reporters on twenty-first Century economic report.

The Shenzhen municipal administration and comprehensive law enforcement bureau pointed out in its recently issued 2019 work plan that it was necessary to start and complete the task of comprehensive management of 600 villages in the city in 2019 and fully start the construction of intelligent city management information project.

In 2018, the Dongguan municipal government issued the "opinions on deepening reform to fully promote urban renewal and upgrading the quality of the city" issued in 2018. It also pointed out that a total of 100 renewal units with a total area of 30 thousand mu should be deployed in the overall deepening of the urban renewal system reform, and a batch of landmark renewal areas and projects should be built within the next three years.

Experience in building services in Hongkong can help

What kind of assistance can Hongkong bring to Guangdong's cities? Reporters learned from the comprehensive interview that Hongkong has certain advantages in infrastructure interconnection, urban planning and intelligent solutions. Over the years, many professional services such as architectural design, engineering, management and surveying have been well known in Hongkong. Hongkong professionals have accumulated rich experience in many urban construction and development projects in the country, Asia and the whole world. They have both international vision and innovative thinking and are familiar with the needs of urban planning in the interior. At the same time, Hongkong is equipped with world-class information and communication technology infrastructure and Internet connections, and it is an ideal test ground for many smart city applications. Ye Zen, vice president of Hongkong Trade Development Council, said.

Take infrastructure as an example, the public transport oriented infrastructure development model (TOD) has many successful cases in Hongkong. As one of the cities with the highest population density in the world, Hongkong's TOD mode helps to maintain urban traffic smoothly and effectively control traffic pollution. Public transport carries more than 80% of Hongkong's traffic volume. In addition, the pedestrian system in Hongkong is also very developed. For example, the corridor system between buildings is very convenient for pedestrians. "I believe that the TOD mode of Hongkong will indeed be more suitable for the mainland than the European and Japanese models." Ju Heng told reporters on twenty-first Century economic report.

Ye Zeen also believes that Hongkong can strengthen cooperation with Guangdong and promote innovation in building materials, technology, design and application in strengthening trade hub towns, designing and planning, and building integrated highways, railways and other facilities.

However, due to the differences between the three standards and norms in Guangdong, Hong Kong and Macau, we still need to fully understand the differences in experience sharing and reference and project cooperation. Taking the aforementioned TOD mode as an example, Ju Heng believes that the corridor system in Hongkong is indeed very worthy of imitation. However, the development of land in China is relatively large, and there is a natural distance between buildings. "Therefore, it is not mandatory to apply ordinary corridor system to solve all problems." We hope that we can draw lessons from the big bay area and give full play to our advantages as a technical adviser, but we can not copy these experiences. " He told our reporter.

In response, a number of respondents told reporters that some of the differences in norms in the big bay area of Guangdong, Hong Kong and Macau can be solved through rapid learning. For example, in project cooperation, it can be agreed to carry out specific operations in the highest standards and norms in three places. For Hongkong enterprises, the more important issue is the qualification restriction. "As the provider of infrastructure solutions, the qualification restriction makes it impossible for us to provide more in-depth consultancy services in the mainland. Before that, we also have some cooperation and exchange projects in the industry, but if we are to promote communication between the two sides under the guidance of the government, we can make deeper cooperation with the enterprises in the Greater Bay area, and let us bring the experience accumulated in Hongkong, especially the international experience, to the construction of the Tai Wan area faster. Ju Heng told reporters.
