The current general BIM modeling software can not reflect the large settlement in reclamation works,so the BIM application management system for the reclamation engineering is created by the secondary development based on commercial softwares.The monitoring data can be imported in real time and dynamic correlation between the BIM model and settlement monitoring data during construction can be achieved.The system integrates the BIM model generation using borehole data,4 common monitoring data analysis and management functions.The construction schedule and engineering quantity management can also be achieved by calling Navisworks.In addition,a special database website is developed,which provides a complete set of solutions for the data storage,safety strategy and data archiving by means of configuring permissions,backuping in different places and data encryption.This system has been successfully applied to the practical project and achieved good results.
