Punan Expressway is an integral part of the Beijing-Taipei Expressway in the national expressway planning network, a typical demonstration project of the national 12 expressway determined by the Ministry of Communications, an important section of the Jinshan Expressway, an important part of the "three vertical and four horizontal" expressway network in Fujian Province, and an important national defense transportation trunk line in the southeast coastal areas. Basically, it adopts two-way four lanes (six lanes are used in some sections of Wuyishan), and it is designed according to two standards of 80km/h and 100km/h, with subgrade width of 26.0m, 99 large and medium-sized bridges 18750.5m, 24 tunnels with 25,254 m, 48 separated interchanges and 4 culverts. There are 6 service areas along the line, and there is a 12 general interchange. Wuyishan Xingtian Interchange is a hub interchange connected with Wushaowu Expressway.
Trial construction agent system of Punan Expressway
In the construction of Punan Expressway in Fujian Province, the management mode of owner plus consulting company and general contracting of engineering construction-a mode of agent construction system was tried out. Agent construction system is one of the most advanced methods in engineering construction management. The specific practice adopted in the construction of Punan Expressway is that the owner Nanping Punan Expressway Co., Ltd. is fully responsible for the project construction management and assumes all the responsibilities of the owner for the project construction.
The agency employs a consulting company with rich experience in expressway construction, which, with the authorization of the owner, directly undertakes part of the management and on-site service functions of the owner, makes suggestions on project construction and assists the owner in project management. The consulting company is not directly responsible for the investment, progress and quality of the project, but is responsible for the correctness and timeliness of the opinions and suggestions put forward in the construction management supervision.
In addition, in order to encourage construction enterprises to invest resources, Punan Expressway has expanded the construction contract scale of each contract section on the basis of the previous total contract scale of 65.438+0.52 billion yuan. There are only three contract sections of this expressway, which are generally contracted by three construction companies. The winning construction enterprise must set up the site project general engineering department, and the senior leaders of the construction enterprise headquarters directly serve as the project chief engineer.
Punan Expressway is the first construction project to adopt the general contracting mode in highway construction, which is divided by three units: China Railway 11th Bureau Group, China Railway 15th Bureau Group and China Railway 18th Bureau Group. Bulk, general contracting and general contracting transactions; Land acquisition and demolition outside the red line shall be changed from local responsibility and cooperation of the construction unit to "independent operation" by the construction unit; Greening, electromechanical and other auxiliary projects. The division bidding was changed to "responsible to the end" by the construction unit; In the past, the owner was responsible for external coordination, but now the construction unit will "show its magic power". This socialized large-scale production construction organization mode will pose a severe challenge to the traditional construction concept that is accustomed to independent operation, calculation while working and change while working. The concept of socialized large-scale production construction with more and more detailed division of labor and closer connection, the cooperation of all units, scientific and accurate engineering design, strict and thoughtful organization plan, attention to accurate calculation of every detail, balanced production in assembly line and efficient and orderly intensive management will become the future development direction of the participating units.
Super band
Fujian Punan Expressway was officially completed and opened to traffic on February 24th, 2008. At this point, the Beijing-Taiwan Expressway from Quzhou to Nanping runs through the whole line.
The completion and opening to traffic of Punan Expressway has opened a strategic channel between northern Fujian and northern China. The Qunan Expressway in Zhejiang Province is an important part of the Beijing-Taipei Expressway in the national expressway planning network. The construction mileage of Kunan Expressway is 332 kilometers, and the Ministry of Communications approved the investment estimate of 1, 4127 million yuan. It is connected to Hangjinqu Expressway in the north and Yin Fu Expressway in the south. It runs through Quzhou, Jiangshan, Erbadu-Zhejiang and Fujian from north to south, and enters Fujian. After entering Fujian, Pucheng, Wuyishan, Jianyang, Jian 'ou and Xiaozuo in Yanping District are connected with Nanping connecting line of Yin Fu Expressway. The total length of the Beijing-Taiwan Expressway in Quzhou, Zhejiang Province is about 16 1Km, of which the total length of Huang Qu section is 73.745 km, with an approved budget of 4.78 billion yuan. The project started construction in August 2007.
