[Purposes]As an important direction of BIM Technology application,BIM lightweight manage-ment system still has many problems in data and model association and matching,component volume and quantity,loading speed and function use.Aiming at the above problems,the BIM lightweight technol-ogy is studied.[Methods]The main methods are as follows:①using computer programming technology,the data processing algorithm of"task package"is developed;②BIM model is lightweight by using digital analog separation technology;③engineering information encoded text information is converted into digi-tal encoded information.[Findings]Using the above technologies,the BIM lightweight management sys-tem realizes the following functions:①it realizes the interconnection of information and data of various engineering projects such as BIM,GIS,Internet of Things,etc;②the attribute data and geometric model information of BIM model are stored separately,and cross model attribute query and application are real-ized;③it effectively solves the problems of BIM model information reading,management and mainte-nance,large model volume,loading speed and so on.[Conclusions]The study has been applied in the HHDQ-1 section of the extension project of Jinan Yellow River Highway Bridge on G104 JingLan line,and achieved good economic and social benefits.
