"Information Isolated Island" phenomenon is restricting the construction industry life cycle management efficiency, and the participating parties are reluctant to share information, which often leads to the emergence of a large number of changes in construction.Based on the unified standard of BIM, the information of all the participants in investment, design, construction, completion stage is created and transmitted in strict accordance with the unified BIM standard, avoiding the information flow distortion during transmission.Firstly, breaking the traditional narrow understanding of BIM, its location in the broad sense as a mechanism raises and establishs BIM standards based on IFC standard in this mechanism.Secondly, the introduction of the system entropy value indicates the degree of order to establish the full life cycle of information transmission architecture model based on entropy and information technology.Finally, on the basis of BIM standards and information transmission model, a building life-cycle collaborative framework is proposed, in order to reduce post-construction changes, which provides a basis for solving the whole process of building "Information Isolated Island" phenomenon.
