1 current situation of construction industry
The construction industry with meticulous division of labor and labor-intensive relies more and more on information, which has become an important asset of enterprises and must be fully utilized and properly protected. Usually, each construction project includes many different stages, such as project start-up, design, construction and maintenance, and each stage requires many companies and institutions of different nature from different places to participate in the whole process of design and construction. The whole implementation process often takes several years to complete, involving a large number of participants, complicated procedures and a large number of documents and drawings, which urgently requires collaborative management. The modern management of large-scale intelligent building projects needs to exchange a lot of information between internal and external participants, including various drawings and schedule control in the design stage; Personnel, materials, progress, quality, economy and other information in the construction stage, as well as various government approvals and legal documents. There are many construction units, and efficient information exchange and management has become one of the keys to complete modernization projects with high quality. In addition, the unique characteristics of architectural engineering, such as dispersion, mobility and disposable, mean that without an integrated information system, engineering-related information will not be well preserved, and it is more difficult to turn it into useful knowledge for future reference. Guangdong's economy has developed rapidly, but a few construction projects have been rejected for lack of basic architectural structure drawings. A large number of social surveys have found that project managers often need to spend as much as 50% of their working time searching for necessary information, which will greatly reduce the efficiency of project management. In a word, accelerating information management has become an urgent task for the construction industry.
The urgent demand of the market is a powerful driving force for the development of new technologies. In order to meet the needs of the development of market economy, in recent years, many domestic companies have begun to intervene in the field of information management in the construction industry, which has made certain contributions to changing the backward situation of information management in the construction industry.
2 Composition and characteristics of construction engineering information
2. 1 Information Form Transfer Form
(1) Text and graphic information. Including survey, surveying and mapping, design drawings and descriptions, calculations, contracts, work rules and regulations, construction organization design, situation reports, original records, statistical charts, statements, letters and other materials.
(2) Language information. Including oral arrangement, instruction, report, work inspection, briefing, negotiation, suggestion, criticism, work discussion and research, meeting information, etc.
(3) New technical information. Including some information collected and processed by modern means such as Internet, telephone, telegraph, telex, computer, television, video and broadcasting.
2.2 Characteristics of Construction Engineering Information
(1) on a large scale. Construction engineering information is all the information that occurs in all stages, links and related units of a construction project. Not only from the construction project itself, such as project overview, design documents, contract structure, contract management system, information coding system, meeting system, supervision team organization, project investment objectives, project quality objectives, project progress objectives, etc. There is also external information from the external environment of the project. Such as: relevant national policies and regulations; Prices, market changes and price indices of raw materials and equipment in domestic and foreign markets; The cost and progress of similar projects; The strength of the tenderer, the reputation of the bidder and the situation of the neighboring units; New technologies, new materials and new methods; Changes in the international environment, etc.
(2) variability. Construction engineering information not only includes relatively stable information in a certain period of time, but also includes a lot of constantly changing dynamic information. Such as: quality, investment and progress information in the project implementation stage; Reflect the actual progress and planned completion of the project construction at a certain moment; Raw materials, machine shifts and man-days actually consumed in the project implementation stage, etc.
(3) Multi-category. Construction engineering information includes organizational information, management information, economic information and technical information, involving many disciplines and categories. Organization information includes: coding information; Company organization information; Project organization information; Project management organization information. Management information includes: quality control information; Schedule control information; Contract control information; Investment control information; Risk management information; Safety management information. Economic information includes: project cost information; Engineering quantity information. Technical information includes: early technical information; Design technical information; Construction technical information; Technical information of materials and equipment; Technical data for completion acceptance.
3 construction engineering information classification and information system
(1) Investment management information. Investment control information refers to information directly related to investment control. Such as: various estimation indexes, various engineering costs, price index, design budget estimate, budget estimate quota, construction drawing budget and budget quota; Project investment estimation; Composition of the contract price; Investment target system; Planned engineering quantity, completed engineering quantity, payment report per unit time, engineering quantity change table, labor and material adjustment table; Statement of claim expenses; Investment deviation and settlement of completed projects; Payment list for completion settlement and construction stage; Raw material prices, mechanical equipment transfer fees, labor costs, transportation and miscellaneous fees, etc.
(2) Contract management information. Refers to all kinds of contract information related to construction projects, such as project bidding documents; Engineering construction contract, material and equipment supply contract, consulting and supervision contract; Index decomposition system of contract; Signing, modification and execution of the contract; Claims for contracts, etc.
(3) Information system. System is an organic whole with specific functions, which is composed of interrelated elements according to specific laws. The generation and application of information is realized through the system, and the information system is a subsystem of the whole engineering system. The building information system consists of the information systems of the owner, the survey and design party, the construction management party, the building material supplier, the construction party and the supervision party. Project management is a multi-objective, independent and interrelated, multi-process, complex and huge system engineering. In fact, the management of a complex large-scale engineering project is to scientifically plan a given goal (schedule, quality and cost) under certain conditions by using controllable resources (manpower, machines, materials, funds and time limit), and make in-depth dynamic analysis with more quantitative data, so as to effectively regulate the implementation of the project and obtain the maximum benefit with as little investment as possible. 4. Establish information systems for construction engineering standards, industry management, engineering management and enterprise management.
Information technology is a high-tech widely used in various industries, and it must be organically combined with industry technology to play its role. In order to standardize, orderly, healthily and efficiently promote the informatization of building construction, it is necessary to formulate the application standards and standardized management information system of building engineering accurately and efficiently, revise the standards in time, facilitate the inspection, inquiry and management of related standards, select standards at any time and place, and check and accept the implementation of standards, so as to effectively promote standardized management. There are many categories involved in the construction engineering industry, such as civil engineering, housing engineering, equipment and pipeline installation, decoration industry, and related real estate industry, survey and design industry, semi-finished equipment, steel structure processing industry, etc. , 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. Traditional management methods and information processing methods are difficult to achieve this goal. The application of modern information technology to establish an efficient information management system for industry management, project management and enterprise management 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. Information technology facilitates the digitalization of entities, shortens time and space, and grasps entities more scientifically. The singleness, times, environment and diversity of engineering projects determine the large-scale, variability and multi-category of project information, and information technology makes engineering a digital project. With the establishment of digital engineering, project management has entered a new stage.
Three systems should be established in the informatization construction of building engineering:
(1) is the technology and control system of architectural engineering design and construction;
(two) construction engineering standards, industry management, project management, enterprise management information system;
(3) It is an Internet-based business information system for construction project scheme optimization, construction bidding, material and equipment procurement and talent recruitment.
