It is called civil engineering. It refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. At present, general civil engineering projects include: roads, water supply, drainage, flood control works and transportation. In the past, all non-military civil engineering fell into this category, but with the increasingly broad engineering science, many contents that originally belonged to the category of civil engineering have become independent disciplines. At present, civil engineering in a narrow sense is civil engineering, that is, building engineering (or structural engineering), bridge and tunnel engineering, geotechnical engineering, highway and urban roads, railway engineering and so on. 1 civil engineering design informatization The rapid development of science and technology after the Second World War made civil engineering develop further on the basis of modern science and technology. The most important building materials-steel and concrete-have made great progress, their strength has doubled, and their reliability, durability and other properties have also been greatly improved. With the continuous development of synthetic materials, the types of materials that can be used in buildings are constantly broadened, and their properties are better than those of traditional materials in the past. The application of new materials with light weight and high strength makes many structures that were difficult to realize in the past possible. The numerical analysis of the computer forced the rough calculation that was difficult to be calculated by hand to be simplified into more accurate calculation and analysis. For example, with the help of finite element calculation software, people can easily solve the internal force and displacement calculation of complex statically indeterminate structures that were difficult to complete manually before. With the development of finite element theory and structural dynamics, people can calculate the stress and deformation of structures conveniently and accurately, which greatly simplifies the design work. The application of computer aided design (CAD) frees designers from heavy manual drawing. The use of more construction machinery has greatly improved the degree of construction automation. 2 The popularization and application of information automation control technology in civil engineering construction can effectively complete difficult construction projects that are difficult to achieve by traditional control methods. For example, the verticality control of high-rise buildings; Quality control of mass concrete construction: automatic feeding control of ready-mixed concrete; Synchronous lifting technology is used to control the integral lifting of large components and equipment, the climbing of integral mould and the lifting control of large scaffolding; Stress control of bridge suspension cable: curtain wall production and processing control; Welding quality control under high temperature and high pressure: building blasting, overall relocation, settlement observation and data acquisition, computer simulation of three-dimensional pipeline layout of large industrial facilities, etc. Information technology will completely change the design technology and construction technology, and its application fields will be wider and wider, the application degree will be deeper and deeper, and the level of building industrialization will be higher and higher. The information technology of civil engineering management informatization is a high-tech widely used in various industries, and it must be organically combined with industry technology to play its role. There are many categories involved in the civil engineering industry, such as civil engineering, housing engineering, equipment and pipeline installation industry, decoration industry, and related real estate industry, survey and design industry, semi-finished equipment, steel structure processing industry and so on. , including many enterprises, constitutes a huge and complex industry information collection, with a very large amount of information. Without a standardized and effective industry management system and efficient operation mechanism, it is difficult to ensure the healthy, orderly and efficient development of all work in this industry. The application of modern information technology to establish an efficient industry and enterprise management information management system can conveniently and effectively analyze the relevant situation of the industry and provide brand-new conditions and possibilities for formulating reasonable industrial development policies, industrial technology policies, industrial development plans and development strategies. At present, the application of information technology makes it very convenient to obtain global industry information, and it is also very convenient to discuss and master the latest management achievements of human beings in domestic and foreign markets, which provides a forward-looking, strategic and more scientific basis for the management of civil engineering industry closely related to human survival and development, and makes the management of construction industry reach a new level. 4. The informatization construction of the bidding management department of civil engineering should mainly include the following aspects: 4. 1 Building a bidding business platform for construction projects. The application, review and release of information, including information release, data upload and download, related information query, etc., are realized by establishing intranet and intranet systems. On this basis, the office procedures of the bidding office and the trading center are closely integrated with the market-related bidding procedures, which effectively promotes the transaction process between tenderers and bidders. 4.2 By using standard bidding forms and automatic bid evaluation system, the bidding documents and bidding documents will be digitized, and the data will be included in the automatic calculation category. At the same time, starting the bid evaluation system can realize computer simulation of judges' scoring. For the data that cannot be automatically processed, such as the places where the judges need to make fuzzy scores according to the contents and experience of the tender, they should adopt the independent scoring method, input their own scoring values, and finally make statistical scores through the bid evaluation system. 4.3 Study economic laws, analyze historical data to establish economic mathematical model, sort out historical bidding project data, analyze corresponding economic indicators and conduct trend analysis. Only after a lot of data accumulation can we analyze the corresponding indicators and trends. Through the treatment of information construction scheme, all data can be revitalized and no data will be precipitated. The analysis results can be used as an important basis for judging whether the quotation is reasonable in the future bid evaluation work. 4.4 Changing ideas, formulating norms and coordinating work need the cooperation of building management departments and related enterprises to enter the information platform together. Because there are many processes involved and there are many contacts between related units, it is even more necessary to change ideas and boldly use information tools. At the same time, it is necessary to formulate data specifications, such as how to format and organize bidding documents, so that all relevant units can speak under the same caliber to facilitate their work. Here, the bidding management office and the trading center will be the leaders of the whole system and play a decisive role. As the initiator of the bidding business, Party A shall actively cooperate with the requirements of the system and conduct digital bidding according to the list specification. For bidding enterprises, we should pay more attention to the changes in the situation and industry environment, make preparations in advance, and actively respond to digital bidding. 5 Conclusion 2 1 century, with the rapid development of information technology, all walks of life are carrying out information construction. The management department of construction project bidding will be able to constantly sum up experience, improve the application level of information technology, realize international integration, and will also be conducive to promoting the healthy and rapid development of construction project bidding in China.
