As the number of prefabricated concrete buildings increases, BIM technology has been practiced more, and the combination of prefabricated concrete buildings and BIM now seems inevitable. This paper mainly introduces the overall application solution of Shanghai Nanxiang Chenxiang Road Station complex project BIM. Before the PC component is produced, the BIM model is applied for deepening design. Through the secondary development of Revit, the steel bar information is automatically exported and quickly input into the steel bar processing equipment to realize the digitalization and batch processing of steel bar. Before PC members enter the construction site, BIM disclosing is implemented to the complicated construction nodes of prefabricated cast-in-situ joint to reduce the site rework. In the process of PC component construction, the progress, quality, safety, business and other management based on BIM are carried out through the information platform independently developed to realize the deep integration of BIM technology and site management. The application shows that BIM technology in PC project plays a significant role in construction schedule and quality management and multi-participant coordination management.

In order to solve the the problems caused by diversifed information in the highway tunnel, this article analyzes the characteristics of highway tunnel and uses big data analysis and assessment of BIM technology to study the tunnel maintenance and optimization. Based on the evaluation of the whole life cycle maintenance and optimization decision method, the article describes the basic principle of whole life cycle information evaluation decision and implementation path, and makes strategic choices according to the evaluation results. Finally, innovation points and application effects of this method are summarized, and the future development trend of the tunnel maintenance evaluation is pointed out.
