施工图BIM正向设计实践研究

Practice Research on BIM Top-Down Design Practice of Construction Drawings

十四五规划提出了“加快数字化发展”的新要求,建筑行业实现数字化转型升级迫在眉睫。BIM技术是建筑数字化的底层数据信息,对于现阶段的BIM技术大量应用于翻模设计,有悖于数字化建设的初衷,并阻碍了数字化建设的高速发展。因此,BIM正向设计的推广是建筑设计行业数字化信息化建设的关键。现阶段BIM正向设计正在个别大型设计院和大型房产企业逐步实施,但其正向设计的经验并未得到广泛推广。本文通过具体工程的施工图正向设计实践,总结设计院BIM正向设计的成果,为正向设计的发展推广和建筑企业数字化转型升级提供借鉴的经验。

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.
