First, the meaning of digital management of building engineering construction
Digital management of building engineering construction refers to the collection and processing of all kinds of relevant data in the construction process, and the scientific analysis and processing of these data through computers, and finally feedback to relevant departments as the basis for decision-making by management. Digital management adopts advanced digital processing technology and equipment, which greatly improves the efficiency and level of construction management, and makes the construction management level of building engineering leap to a new development level.
Second, the status of China's construction project construction management
The application of digital management in the construction of China's construction enterprises is still in the primary stage of development, and the advantages of digital management have not yet been fully exerted. Outstanding performance in the following aspects:
(a) Low information and data transmission capacity
Most construction enterprises in China lack innovation ability and still adopt traditional construction management mode, which makes the whole management work efficiency and transmission ability low. Without the support of data and information, plans and resolutions will affect the decision-making of management, and the final decision often depends on the experience of leaders for many years.
(b) There is no data to accurately measure costs.
At present, most construction units in our country only make a rough estimate of the cost, without detailed planning and systematic management, and there are many extra expenses that are not budgeted, which leads to the inability to control the cost in the construction process.
(3) The data and information are not computerized.
At present, except for those large-scale real estate development projects and national projects, most other domestic construction projects are still semi-information-based, which makes the information reserves of construction companies insufficient to improve data reference for the next construction. The backward information management of construction enterprises has seriously hindered the development of construction industry.
Third, the advantages of digital management
In building engineering, compared with traditional manual information management, digital management has the advantages of networking, intelligence, information digitization and visualization. The implementation of digital management in building construction can input all the data of the construction process into the computer, and use modern electronic equipment to monitor, manage and predict the whole building project through intelligent analysis of software. Through objective and accurate digital analysis, managers can not only control the whole construction project comprehensively and accurately, but also know the local operation situation in time, so as to make correct decisions in time.
Fourth, the necessity of adopting digital management
(1) Digitalization of construction management is the need for effective use of information resources.
Information is a kind of resource. If it cannot be effectively stored, processed and transmitted, it is a waste of resources. For example, taking concrete pouring in the process of building construction as an example, the data before pouring are almost ignored except the strength label and quantity of concrete. The neglected concrete suppliers, mixers, cement, sand and other raw materials, such as physical and chemical quality, factory time, weather conditions, transportation time and road traffic conditions, are all related to the quality of concrete. After the completion of pouring, the data except pouring position and cubic number are almost completely ignored, and the neglected concrete tamping operator, test block, maintenance and steel bar production are also related to the engineering quality.
(B) "real-time" grasp the needs of many uncertain factors in the project.
Industrial production can be automated because there is a feedback mechanism, which can feed back the deviation of the construction process to the control system in time, and the control system can adjust it in time, so as to keep the production process relatively stable and controllable. However, the operation of construction projects is not always controlled. Some project managers may know that sometimes they can't get a data of functional departments for a long time. Everyone doesn't know the running state of the system, how to control it? Cost, construction period, quality and the interaction of many uncertain factors in the project. The biggest headache for project cost managers is that they can't grasp accurate project cost information in real time. The cost information after cost accounting has become "yesterday's flower" for project management decision-making. All these strongly call for the "informatization" of project cost management.
Five, the application of digital management in construction engineering.
In building construction, digital management is mainly embodied in spatial information technology, supervision and monitoring technology, virtual reality technology and so on. The application of these new digital management technologies has greatly improved the traditional construction management.
(a) space information technology
Building spatial information technology refers to the use of advanced GIS, remote sensing system, global positioning system (GPS) and other new spatial information technologies, through the scientific management and comprehensive analysis of all spatial information such as topography and geological conditions of construction sites, to provide a basis for leadership planning and decision-making. It is of great significance to display the overall situation and process of the whole building construction in a three-dimensional or four-dimensional visual way by combining GIS with system simulation technology, so as to grasp the construction situation, improve the project construction scheme and method in time and strengthen the coordination of all aspects of construction.
Supervision and monitoring technology
Compared with the traditional equipment management mode, the digital monitoring technology of engineering equipment has higher management efficiency. It can monitor water supply and drainage, HVAC, lighting and material transportation in real time. It can also supervise whether workers operate according to regulations and wear safety helmets and safety belts. Therefore, the digital management and monitoring system can not only facilitate the monitoring, control, scheduling, operation and comprehensive management of mechanical and electrical equipment, but also ensure the quality and safety of engineering construction to a certain extent.
(3) Virtual reality technology
Virtual reality technology is a technology that uses computer-related technologies to generate realistic simulation environment, so that users can have immersive feelings or experiences. The application of this technology can improve the trainee's extremely realistic "practice" experience, and through this realistic "practice", improve the coping ability in practical operation and reduce unnecessary losses or casualties. Virtual reality technology can also compare different construction design schemes, provide help for construction management and ensure the reliability of construction schemes.
To sum up, the digital management in building construction in the new era is the need of project management modernization and the inevitable trend of the digital age. With the intensification of competition, construction enterprises urgently need to use digital management to strengthen scientific management, reduce costs, improve efficiency and enhance their comprehensive competitiveness.
