As the pillar industry of national economy, construction industry is in a new stage of development by leaps and bounds. In order to meet the increasingly severe domestic and international competition situation, based on the new means of information technology, comprehensively helping construction companies to transform their technology and improve quality and efficiency has become the key to sustaining the core competitiveness of construction companies. With BIM technology in the sustainable implementation of China Construction Eighth Engineering Division Co., Ltd., the BIM data created by construction projects is increasing, and it is more and more difficult to control the accumulation of The control of BIM data is becoming more and more difficult. Developed with independent control of intellectual property based on BIM collaborative management platform, China Construction Eighth Engineering Division Co., Ltd., in helping the site at the same time, it realizes centralized control of BIM data and various engineering and construction data created by each unit. CIM is based on three-dimensional city based on urban spatial geographic information, it is an extension of BIM in the urban context. This paper studies the data integration application of BIM and CIM platform, and sort out the data resource standards on the basis of BIM collaborative management platform. Based on the BIM collaborative management platform, this paper composes the data resource standards, and realizes the high efficiency integration from BIM to CIM through light processing, data-mode separation and data fusion. Therefore, the integration from BIM to CIM will be seamless and effective.
