Although there are some systems based on computer-aided design and project management software, these systems usually have single functions, cannot comprehensively consider various construction needs, and lack real-time progress and quality monitoring, and cannot effectively realize the dynamic management of the construction process.

Through progress deviation analysis and quality monitoring feedback, the system can promptly identify possible progress delays or quality problems in the construction process, helping project managers to adjust the construction plan in a timely manner to avoid construction delays and quality problems.

[0101] The pipeline conflict detection and optimization module can automatically detect spatial conflicts between pipeline systems and between pipelines and building structures, and provide visual feedback through the BIM platform to provide designers and construction personnel with clear conflict locations and solutions. This module can not only perform conflict detection before construction to avoid later rework caused by design defects, but also adjust pipeline layout according to real-time progress during construction to ensure smooth pipeline installation;

In addition, the system can automatically generate various reports and analysis reports to facilitate managers to fully control the progress, quality and cost of the project.

[0105] Based on the visualization function of the BIM model, the entire construction process will become more transparent. Each stage and each task of the project can be viewed and tracked in detail through the BIM system, and construction personnel and managers can monitor and adjust more efficiently. Through this transparent management, problems that arise during the construction process can be quickly discovered and solved in a timely manner, reducing the risks caused by information lag or poor communication.
