This paper aims to explore the application of information technology in modern architectural engineering. Through the analysis of its application status

including the penetration and deepening of BIM

Internet of things

big data and other technologies

as well as the problems of poor system compatibility and information island. Combined with the actual case

the customized application strategy and technology optimization promotion path based on the project requirements are constructed. The research shows that information technology can effectively improve the project benefits

but its deep integration needs to break through the barriers of technology and management

which is of great significance to promote the transformation of the construction industry towards digitalization and intelligence.
