Information technology is a general term for enterprises to collect, store, process and process management information by scientific methods and assist decision-making, and computer technology is the main and indispensable means of information technology. As far as the promotion of building management informatization is concerned, it is not just a question of whether to use computer technology. We still need to solve the problem of how to use it. If all departments of enterprises use computers, information exchange between enterprises and between enterprises and governments still needs paper media. It can't be said that information technology has been fully utilized and informatization has been realized. At the same time, using modern computer construction management can not only store, modify, search and process a large amount of information quickly, effectively, automatically and systematically. Moreover, it can track and manage the construction progress, quality and cost caused by various natural and human factors in the construction process. The application of computer technology reflects the application level of information technology, which improves the construction management level. 1, application status of domestic construction management informatization At present, computers and tools and software are mostly used in large-scale construction project management, which improves work efficiency. Such as office automation system, bidding system (engineering quantity calculation, bidding quotation, tender preparation, construction scheme design, project schedule network preparation), project management system (project cost, quality, schedule management, daily information management), etc. The popularization and application of information technology not only improves the overall image of construction enterprises, but also improves work efficiency, technical level and safety level, thus enhancing the overall competitiveness of enterprises. It also reduces the production cost and work intensity of enterprises. The project quality is guaranteed. But ... generally speaking. At present, the overall level of informatization application in construction enterprises is low, and there are obvious limitations and deficiencies. It is mainly manifested in the following aspects: (1) has a narrow application range, mainly focusing on the early stage of project construction, such as bidding and construction organization design, but less application in progress, quality and cost control during construction. Project construction management still mainly depends on the experience and processing ability of managers, which is very unscientific; (2) The main application is stand-alone application software, and stand-alone operation only takes advantage of the fast operation speed of the computer. No network has been formed, and information sharing and automatic transmission have not been realized. Low efficiency; (3) Enterprises fail to make full use of the convenience brought by the Internet to realize online material procurement, bidding, project management, information exchange and information release. And e-commerce has not really developed; (4) No matter government websites or commercial websites, most of them focus on information release, lacking tools, network software and information interaction; (5) Software development projects are similar, lacking overall planning and development funds, and most of them are low-level repeated development. 2. Successful experience of foreign counterparts in the application of information technology. Foreign construction enterprises applied information technology earlier and have many successful experiences, which are worth learning from. For example, in recent years, Japan has vigorously promoted the informationization of the whole life cycle of construction projects, namely CALS/EC. Its characteristic is that all information in the whole life cycle of a construction project is electronic; Use the Internet to submit and receive information; All electronic information is stored in the database for enjoyment and reuse, thus reducing costs, improving quality, improving efficiency and enhancing the competitiveness of the construction industry. In western Europe (Germany, France and other countries), the main applications are: formulating general standards and developing general data infrastructure, so that people engaged in construction business can conduct electronic communication; Using the Internet and computer technology to effectively obtain and exchange engineering project information; Manage engineering drawings, data and drawing review by electronic means; Using digital camera technology to dynamically manage the site construction situation in time; Personnel management on the construction site adopts "green card certification" (green card contains basic information of employees, employment, skills and other information). 3. Thoughts on Improving the Application Level of Construction Management Information Technology (1) Enterprises should make strategic plans according to the characteristics of construction management informationization and implement them effectively. The Ministry of Construction lists informatization in the construction field as an important work at present. It is not a fashion or an ornament to promote the work in the construction field by means of information technology, but an urgent and urgent problem. In particular, it is necessary to strengthen the informatization construction of engineering quality management. It can be seen that it is the general trend to transform the construction industry with information technology. The core of the informatization level of construction enterprises is mainly reflected in the application level of information technology in the process of construction management. Enterprises should combine the actual situation of construction management, make strategic planning, make full use of modern information technology, gradually establish various construction management information systems, and control them with PDCA cycle process. At present, the power transmission and transformation company has formulated the outline plan of informatization, and promoted informatization management according to the idea of "continuous improvement of personnel, hardware, software and management". (2) Information sharing platform and online office system based on LAN and Internet are widely used in the whole process of construction management. First of all, by making full use of information technology, the management of construction enterprises widely applies the information sharing platform and online office system based on LAN and Internet in the whole process of construction management, which can minimize the mistakes in information transmission. Thirdly, by using information technology to develop the project information management system based on the Internet, establish the connection between the database and the network, establish the concept of virtual organization on the Internet, change the vertical information exchange mode into a parallel communication mode, improve efficiency and accuracy, realize information resource sharing, improve communication and cooperation, improve the scientific and timely decision-making, and then realize the information management of the construction process. For example, the project manager can hold a virtual work meeting at any time and any place in the day; Project team members can exchange information with relevant engineers anytime and anywhere, review construction quality and countersign drawings and documents; Construction site management personnel can directly access the construction quality inspection information to the company headquarters for evaluation through PDA; In the completion acceptance stage, various completion data are automatically generated according to the quality records. At present, our company has basically realized the flat management of the construction management process through the information sharing platform and online office system. (3) Vigorously improve the application level of computer-aided construction project management software. At present, it is necessary to vigorously promote the application of software related to the three major control processes (schedule, quality and cost) of construction management. For example, in the aspect of schedule control, network planning technology can show the characteristics of key work, maneuvering time and mutual restriction. According to the construction schedule, network schedule management software is used to control the schedule, adjust resources and optimize the time in time to adapt to the changeable situation of the construction site. At present, this kind of software is relatively mature; In terms of quality control, engineering quality management is an important part of construction management, which has the characteristics of large amount of information, strong comprehensiveness and high technical difficulty. Compared with manual operation, using quality management software has outstanding advantages. The processing time is short and the reliability of the result is high. The quality management software system can be used for quality control and evaluation at all stages of the construction process, including generating various quality evaluation reports, drawing various quality evaluation curves, and evaluating the engineering quality grades of some projects according to various measured data, thus providing reliable material guarantee for quality managers to dynamically control the engineering quality. But as far as the most urgent goal that directly affects enterprises is concerned, it is still cost control. The upcoming reshuffle of unemployment in the construction industry will also be largely related to cost control and lending capacity. Therefore, in cost control, it is inevitable to establish and apply the construction project cost management information system. The power transmission and transformation company is currently in its infancy. (4) The informatization construction of construction project management needs business process reengineering. Management informatization is a systematic project and the introduction of a brand-new management concept, management method and management mode, which will have a great impact on the working style of every employee and change people's way of thinking. Therefore, the promotion of management informatization can only be gradual, not overnight. The construction of management informatization needs to constantly recreate the business process of enterprises with innovative spirit, so that enterprises and employees can gradually adapt to the impact brought by management informatization. The traditional business process of construction enterprises is segmented, and the focus of each segment is only a single task and work, rather than the global optimization of the whole system. There are many problems such as chaotic management and ineffective business process duplication. In the construction of management information system, if we only use computer system to simulate the original manual management system and digitize the original business system, it is impossible to fundamentally improve the competitiveness of enterprises. According to the characteristics of information technology, BPR fundamentally rethinks and designs the business process formed in manual mode, and needs to break through the traditional thinking mode, management method and organization and integrate the original business process. BPR is an important way to improve the efficiency of enterprise projects, an insurmountable stage for enterprises to realize management innovation, a profound change in management foundation and a process of management innovation. Only this kind of "thoroughly remould oneself" reform can make the project management of enterprises get rid of the predicament completely and regain a new life. Management information system embodies advanced management ideas, and BPR is the essence of management information system from beginning to end. Management information system can be regarded as a means in the implementation of BPR. The two complement each other and are indispensable.
