The research achievement "Research on the Integration of Information Technology and Platform for Construction Engineering Based on BIM" won the second prize in the 2018 "Huaxia" Construction Technology Award. The research aims at solving the problems caused by the fragmentation for information in various stages of construction projects, the difficulties of multi-participant collaborative works. From the aspects of theory, technology, platform, and application, our group carried out systematic researches on the information technologies for construction engineering platform based on BIM. The BIM-based platform and multiple software system, developed with completely independent intellectual property, have been promoted and applied in a vast number of large-scale projects in multiple engineering fields such as buildings, highways, bridges, subways, and corridors. It improved the collaborative work efficiency and informatization management level for projects, and have significant social and economic benefits. In addition, another project that we participated in, "Research and Application of Modern Construction Technology for Super Large-scale Underground Ecological Water Plants in the Central City of Beijing" has won the third prize.
