Abstract:In order to study the specific content and implementation path of BIM digital integration application under the background of intelligent construction, relying on Suzhou Fengli Street South Extension Project, three major requirements of BIM are summarized, namely technical application, data transmission and data-driven intelligent construction, and the working ideas of integrated BIM application are given. A method for information transmission and integration of digital-analog separation based on component coding is proposed to improve the effectiveness and operability of data transmission. The BIM data-driven steel bar processing, 3D roadbed paving and visual progress management are achieved to improve the construction efficiency and accuracy. The comprehensive solution for BIM digital integration application has been formed, which provides the reference and guidance for BIM and intelligent construction applications in similar projects.
