Description

Technical Field

[0001] The present invention relates to the technical field of progress supervision, and in particular to a construction progress supervision system and method for a building decoration project based on BIM. Background Art

[0002] The construction progress supervision system of building decoration projects based on BIM is an intelligent construction management tool widely used in the field of building decoration in recent years. BIM (Building Information Modeling) technology integrates all information of building projects from design, construction to operation and maintenance through the establishment of digital three-dimensional models, providing data support and management capabilities for the entire life cycle. Compared with the traditional construction management model, BIM technology can more intuitively display the building structure and decoration effects, and realize dynamic monitoring of the construction process through real-time data association. Among various construction projects, the decoration projects of stadiums and gyms are particularly complex, involving construction coordination and precise management of different functional areas. Such projects usually include multiple areas such as auditoriums, main venues, and fitness equipment areas. The construction is difficult, the time requirements are strict, and the standards for visual effects and functional zoning are high. Therefore, BIM technology is greatly needed to ensure the accuracy of the construction progress and the consistency of the decoration effects.

[0003] In the specific decoration projects of stadiums and gyms, traditional construction management methods usually rely on manual data recording and regular progress reports, which have problems such as information lag, inaccurate construction progress, and unreasonable resource allocation. Especially in the face of complex construction environments and high-standard decoration requirements, there is a lack of automated data collection and analysis methods. For example, data such as workers' working hours and equipment utilization rates are often difficult to summarize and analyze in a timely manner, resulting in inaccurate assessments of construction intensity; at the same time, the influence of environmental factors such as temperature, humidity, and air quality is often ignored, and the adaptability of the construction environment is not effectively controlled. In addition, the lack of real-time monitoring of project resources leads to frequent material shortages or waste of resources, which affects the construction progress and overall quality. Under the traditional management model, there is often a large deviation between the actual progress of the construction project and the target progress. There is a lack of accurate progress warning mechanism, and it is impossible to detect and correct the deviation of the construction progress in time, which increases the risk of construction period.

[0114] Example 4

[0115] This embodiment is explained in Example 1, please refer to Figure 1 Specifically: the construction progress warning unit is used to compare the progress prediction index Jdyc with the preset standard threshold Z and the preset standard threshold X, to perform a graded evaluation on the execution of the construction progress, and then formulate a specific improvement strategy;

[0116] The progress prediction index Jdyc ≥ the preset standard threshold Z, and the first construction status level is obtained. The construction progress exceeds the expected progress by more than 20%, and no significant adjustment is required. Since environmental factors may change over time, it is necessary to continuously monitor the temperature, humidity, noise and air quality of the construction environment to ensure that the environmental adaptability remains at a high level. For areas that are close to completion, the work standards can be appropriately improved and details can be polished, such as improving the decoration effect and improving the accuracy of equipment debugging, to ensure the overall project quality;

[0117] The preset standard threshold value X≤progress prediction index Jdyc<preset standard threshold value Z, and the second construction status level is obtained. The construction progress meets the standard, but there are deviations and adjustments are needed. For areas with slightly insufficient resource allocation, an appropriate number of construction personnel and material reserves can be added, and equipment maintenance can be ensured in time to avoid resource bottlenecks. The construction plan for inefficient areas can be fine-tuned, for example, the working hours of key nodes can be appropriately extended to ensure completion within the established construction period. For construction environments that do not meet the optimal conditions, temporary environmental control measures (such as installing mobile air conditioners or adding ventilation equipment) can be added to improve the comfort and efficiency of construction personnel;

[0118] The progress prediction index Jdyc < the preset standard threshold X, and the third construction status level is obtained. The construction progress is more than 20% lower than the standard, and there is a deviation. Immediate intervention measures are required to quickly deploy additional construction personnel and materials to key areas to ensure that key nodes are completed on time. At the same time, construction hours are increased, such as implementing a shift system, re-evaluating the construction task arrangement, optimizing the process and concentrating it on the delayed area, ensuring an increase in construction frequency and task completion, and directly improving the temperature, humidity and air quality in the construction area by using environmental control equipment (such as large air conditioners, dehumidifiers, etc.) to ensure the adaptability and comfort of the working environment of construction personnel.

[0119] The automated progress analysis unit is used to perform real-time analysis on the difference between the actual progress and the planned progress, and provide automated deviation feedback.

[0121] The data integration unit is used to integrate the real-time data of each module to ensure that the report information is comprehensive and accurate and to support subsequent data analysis and presentation;

[0122] The visualization unit is used to generate visual progress reports through charts, curves and 3D displays, so that the management can intuitively understand the construction progress and problems, and provide decision support for the management based on progress forecasts, deviation analysis and resource allocation suggestions.

[0123] In this embodiment, the design of the construction progress warning unit, the automated progress analysis unit and the report generation module enables the system to have efficient and accurate construction progress monitoring and feedback functions, which produces significant beneficial effects. Through the construction progress warning unit, the progress prediction index Jdyc is compared with the preset thresholds Z and X, and the system can grade and evaluate the construction status, and then automatically formulate corresponding improvement strategies: when the construction progress exceeds the expectation and does not need to be adjusted, the progress has a slight deviation and needs to be adjusted moderately, or the progress is significantly lower than the standard and needs immediate intervention, the management can obtain clear guidance plans to ensure that the project is advanced on schedule. The automated progress analysis unit further provides automated deviation feedback by real-time analysis of the difference between the actual progress and the planned progress, so that potential problems can be quickly discovered and corrected, significantly reducing the risks caused by construction delays. At the same time, the report generation module integrates the data of each module to form a comprehensive and accurate real-time report. Through the visualization unit, the management can intuitively understand the current construction progress, deviation and resource allocation suggestions through charts, curves and 3D models to ensure comprehensive control of the construction status. Overall, the system's progress warning, automatic analysis and visual display have greatly improved the accuracy and response speed of construction management, effectively ensuring the reliability of construction progress and the possibility of project completion on schedule.

[0132] In this embodiment, the construction progress supervision system of building decoration engineering based on BIM has significant beneficial effects by implementing BIM model construction, data collection, progress analysis and visual reporting in steps.

It not only shows the building structure and decoration effect, but also dynamically associates the construction progress and real-time data, laying the foundation for subsequent monitoring and analysis. Secondly, through the real-time collection and coefficient calculation of construction intensity, environmental adaptability and resource input data achieved in steps 2 to 4, the system can dynamically evaluate various construction parameters, ensure construction efficiency, environmental adaptability and rationality of resource allocation, and help to keep the construction going smoothly and avoid waste of resources.
