Abstract:

Intelligent construction is supported by technologies such as the Internet of Things, big data,artificial intelligence and BIM. However, the application of BIM in cost management is still relativelylimited. In response to the practical difficulties of BIM cost collaboration in the entire life cycle under theintelligent construction model, a core intelligent management and collaboration system for project cost isconstructed from the perspective of the construction party,which includes system guarantee, modeldeepening, data integration, quality inspection and evaluation, and measurement management. Theapplication effect of intelligent cost collaboration management is verified by relying on a large and complexproject. The research shows that this system significantly improves the quality of the model and theefficiency of engineering quantity calculation through the model review system and standardized modelingprocess. By matching the entity division with the list code, the quality inspection and evaluation arevisualized and the measurement and payment data are linked. However, the measurement of out⁃of⁃modelengineering quantities is difficult, and the shortage of compound professional talents still restricts thecollaborative efficiency. To break through the application bottleneck, it is necessary to improve datastandards and expand the scope of measurement based on the model, to promote the in⁃depth integrationof intelligent construction technology into the entire life cycle of engineering management.
