BIM正向设计存在的问题和思考

Problems with and reflections on BIM forward design

BIM正向设计能够减少部分建模环节、降低劳动和信息交换成本,其优点得到业界的广泛认同。随着国内BIM技术的不断推广,现有的BIM咨询模式已不能满足快速发展的应用需求,正向设计在实际应用过程中也遇到了很多困难。通过工程经验和文献调研总结了正向设计存在的问题,如:①缺乏与之适应的标准;②国内环境的制约;③技术链和产业链不够成熟等,并对上述问题进行了思考与分析,得出以下结论:以出图为导向的正向设计是BIM技术应用的过渡性策略,需补充相适应的标准体系、加大国内BIM软件和云平台体系的开发力度、促进设计与施工管理一体化。正向设计的推广不仅需要有力的技术支持,更需要管理模式的不断创新,为BIM技术的应用和发展提供保障。

The BIM forward design has become widely recognized due to its advantages of simplifying the modelling process and reducing costs of labor and information exchange.As the BIM technology has been increasingly popularized in the architecture industry in China for many years,the current BIM consulting model cannot satisfy the highly demanding application.Many challenges still remain when the BIM forward design was applied in the practical projects.This study performed a critical survey based on the practical experience from many projects and the literature investigation,so as to summarize the existing questions as follows:①the lack of adaptive standards;②domestic constraints;③underdeveloped related technical and industrial chains.Based on the analysis of the mentioned questions,several conclusions can be drawn such as:The drawing-oriented application is a transitional strategy.The effective solutions for developing the BIM forward design should be based on the adaptive standard.The domestic BIM software and cloud platforms should be developed,and the integration of design and construction management should be reinforced.Not only is the strong support of technical required,but the innovation of management mode is needed to guarantee the application and development of BIM.
