1 overview
With the continuous expansion and improvement of the construction scale, the changes in the investment subject, investment mode and management mode of highway construction projects have brought about diversification and complexity of highway construction project management. The new situation requires higher and higher management level of all participants in highway engineering construction. The strength of management ability and operational efficiency will directly affect the construction quality, project progress and management efficiency of construction projects.
2. Research on the current situation of industry development
Take expressway management as an example, and its management status is shown in figure 1. Provincial highway construction management has the following characteristics: (1) Highway engineering construction management follows the basic project construction management procedures; (2) There are many links in highway engineering construction. To realize the dynamic supervision of the project, it is necessary to implement the supervision of "all matters, all processes and all fields"; (3) In the process of engineering construction management, there is information exchange and business collaborative management with many departments inside and outside the industry. For example, the cost station needs to examine and approve the project investment estimation, preliminary design budget, construction drawing design budget, unit price change, final accounts and other links, and the quality supervision station needs to perform industry supervision duties on safety production during construction. Therefore, it is necessary to establish a platform for information sharing and business collaboration in the whole process, so that all departments can get what they need and realize highway construction management efficiently.
3 Explore the existing problems
3. 1 backward management methods and low management efficiency.
At present, the traditional conventional management mode is still implemented in highway engineering construction management, and the management means are far from meeting the demand. Informatization has not been widely used in various management activities, and daily engineering construction management cannot be controlled in time and effectively. Any problems in the construction process can't be found in time and reported to the superior. After the problem is found, emergency measures cannot be taken in time, which leads to delay in handling and even expands the impact of the problem.
3.2 Poor data collection and lack of support for applications.
At present, the basic information of construction enterprises, supervision enterprises, testing institutions and personnel related to highway construction mainly exists in the form of information submitted by the Bureau of Commerce, and it is impossible to obtain the operation and construction behavior of enterprises in time; However, a large number of basic information, construction information, supervision information, safety information and punishment information of enterprises and personnel are in the hands of industry management departments such as administrative licensing, law enforcement supervision and daily management, and the automation and electronic collection of basic information has not been realized, which makes the authenticity, integrity and timeliness of information impossible to guarantee. Information related to highway engineering construction cannot be effectively collected, data mining and analysis cannot be effectively utilized, and data cannot play its due supporting role in construction management and leadership decision-making.
3.3 There is an "information island", which makes it difficult for the industry to enjoy it.
At present, the highway construction management industry has not yet formed a complete and sound industry basic information database, and the basic information of external enterprises, institutions and personnel is scattered. Each business bureau only keeps part of the basic information of the directly affiliated enterprises, and the sources of information are diverse, including paper information submitted by enterprises, manual entry by business personnel, and sharing of some information by superior leadership departments, which fails to achieve centralized sharing of information of enterprises, institutions and personnel in the industry. In highway engineering construction, the importance of engineering documents is self-evident. Poor management of electronic documents is an obstacle to the technical accumulation of construction units. It is common that the project department lacks professional file managers. Sudden arrangement is the disadvantage of technical file management, and the management mode and storage mode are the fundamental reasons that affect data reuse.
3.4 traditional cost management, lack of prior prediction and planning
Highway project construction cost management is a key problem to be solved in the process of engineering construction. At present, due to the lack of market information, the construction unit lacks the understanding and analysis of the market price of building materials, the cost consciousness is formed late, the scientific cost prediction and decision-making are lacking, the control in construction and the cost assessment after construction are lacking, the cost management content is incomplete, and the overall awareness and thinking are lacking. 3.5 The supervision mode of engineering construction is single and cannot be corrected in time. In the implementation stage of engineering construction, some project undertakers have poor performance ability and lack of integrity, and the contract performance rate is low during the implementation of engineering construction. Failing to provide relevant technical personnel and equipment as agreed in the contract, and replacing the main management and technical personnel such as project manager, supervision engineer and testing engineer at will, and the certificates of "three types of personnel" are incomplete.
