Abstract：Research purposes:The development of 3G network will bring new opportunity to the informatization construction of traditional industry，high-speed mobile communication technology resolve the problem that construction enterprises in the project management information construction is subject to a fixed network link. This paper aims to establish a scientific and rational mobile information system model，combined with a large construction enterprise mobile information system construction practice.
Research conclusions:(1)Mobile information system based on 3G technology has the advantages of convenience，ease of use，economy，security，and is suitable for construction enterprise deployment and application;(2)To build enterprise mobile information system architecture framework model，should be user-oriented，open up the process， subdivision business，real-time seamless，security-conscious;(3)The models can be used to design and implement monitoring and visualization of construction safety management，mobile office，digital chemicals and other mobile information applications;(4)Mobile information system also has security and ease of use，technical updates fast， uneven development and other issues，but the idea of mobile information service applications will gradually mature，the application level will continue to deepen.
