First, the principle of building construction information management
1. 1 building construction information system integration
Due to the influence of the workflow of the construction industry, a large number of industry, local and national quotas are adopted in the process of project approval and bidding for construction projects, and the management system is complex and the data calculation is large. Therefore, how to use the standard flexibly is the content that all construction units must pay attention to, and it is also the main basis for their project cost calculation. In the project implementation process of the construction unit, it involves capital accounting, planning progress, quality and safety, norm cost, materials and equipment, personnel management, design change, subcontracting management, etc. These are all elements that can't be ignored in project management. Therefore, the development and use of construction engineering information system must consider the above effects. In the process of data center establishment and process reengineering, it is necessary to break through the limitation of individual application of each department, link all contents scientifically and organically, realize joint monitoring of various business modules, effectively coordinate the working relationship between the construction engineering department and relevant units, and finally form an all-round and full-process working environment.
1.2 multi-layer construction management platform
In the process of building construction project implementation, it involves the interests of the construction unit, design, supervision, superior management organs and local governments, and involves many links such as on-site construction management, contract management, budget management, mechanical material management, financial management and so on. Therefore, the information management of construction projects should also fully consider the different needs of different participants, so as to establish a multi-level network information platform and software system including remote monitoring, on-site construction management, unit intelligence and knowledge management, and multi-party coordination of projects. And can automatically generate its data for different subjects, and realize the information management of various resources.
1.3 Strengthening the adaptability of construction project management
In building engineering, highway engineering and railway engineering are greatly influenced by environmental factors such as weather change and geological conditions, while housing engineering and municipal engineering are greatly restricted by the requirements of urban construction permit time, weather change and environmental protection, which will affect or even determine the investment and progress of engineering resources, and at the same time improve the difficulty of cost prediction and weaken the accuracy of cost analysis. Therefore, the construction engineering information system should have the function of setting construction parameters, so that users can customize relevant parameters according to the environment where the project is located, so that the system operation is more in line with reality and the accuracy of feedback information is improved; At the same time, in the construction project management, under the premise of ensuring the quality and safety of the project, managers are most concerned about the cost and progress of the project. Therefore, the system should also establish the connection between cost control and project progress, so as to provide the actual cost in project management in time according to the completed engineering quantity, and compare the budgeted cost with the actual cost in real time, so as to put forward cost control suggestions and predict the development trend of cost. In addition, because the project management will directly face the site construction, the interface of the system should be designed as convenient and concise as possible, reducing the workload of data input, strengthening various operation prompts of data input, and setting functions to avoid misoperation.
1.4 Digitization of construction process
The process of project management is actually the process of data transfer and flow among project participants. In the traditional management mode, information is carried out repeatedly and slowly by fax, telephone and written notice. And obtaining the information of a single link can only be completed through the cooperation of relevant departments, which reduces the economy, effectiveness and timeliness of information transmission. In order to prevent overlapping and duplication of work, improve the speed and quality of information transmission, the project information system must implement data management, and the work content and responsibilities of project participants are also based on data management, so that as long as everyone does their personal work well in the project, the system will automatically realize business flow.
1.5 Real-time Implementation of Construction Engineering Database
At present, the domestic construction market generally adopts the method of compiling bidding quotation according to the budgetary estimate published by the construction unit or design unit, which actually reflects the quota of the construction unit. Excluding market occupation, vicious competition and other factors, the bid price is actually the highest cost that the unit can bear. In fact, the project under construction undertakes many functions, such as accumulating the actual cost of similar projects, accumulating project management experience, establishing the reputation of the construction unit, evaluating contractors and so on. Therefore, the construction project information system should be equipped with general material library, template, supplier and contractor database and various contract templates that meet the quota of the construction unit. Users can maintain and delete them according to the needs of the site, and it is also conducive to the reference and direct call of other projects.
Second, the three systems of information construction of construction engineering
1) architectural engineering design and construction technology and control system;
2) Information system of building engineering standards, industry management, engineering management and enterprise management;
3) Internet-based enterprise business information system for construction project scheme optimization, construction bidding, material and equipment procurement and talent recruitment.
