Study on Construction Quality Control of Urban Complex Project Based on BIM

Urban complex of high efficiency, complex, intensive determines its modernization, urbanization, internationalization of the inevitable product. And it will become the city's landmark buildings and promotes local economic and cultural development. In the construction of urban construction should be quality-oriented, because of which BIM information sharing, features and functions for the construction of the project providing a lot of help to provide quality protection to ensure that construction quality standards Based on the construction of urban complex project, this paper analyzes the construction characteristics and construction quality control difficulties of the project. Then combining BIM technology and AR technology in the concrete application of the construction stage, the project construction quality is enhanced through prior control anf prosesscontrol and post control. Construction quality control for the future urban complex and the use of BIM technology aims to provide reference and improve project quality and construction industry production efficiency.
