“十四五”规划提出了加快新一代信息技术同各产业深度融合，加快数字化的发展，推进数字产业化和产业数字化，培育新技术、新产品、新业态、新模式，打造数字竞争新优势的明确目标。中国建筑业正经历着行业变革的阵痛，房地产去泡沫、制造业去产能导致需求迅速下滑，建筑业企业正面临着前所未有的发展和转型压力。BIM（Building Information Modeling，建筑信息模型）的出现有力地推动了建筑业的数字化发展，为传统的建筑业注入新的活力，是企业进行技术升级和生产方式革新、提高自身竞争力的有力手段，而在推广应用中却存在许多问题，如何有效地应用BIM是各大企业关注的焦点。

      本文首先在搜集国内外BIM应用、研究文献的基础上，结合实际工程案例，分析目前国内BIM应用的现状和存在的问题；其次，通过工程项目全过程管理目标与需求分析，并探讨工程项目不同建设模式对于BIM应用的影响，从BIM应用点选择、BIM应用组织建设和职责划分、BIM应用流程和协作策略设计三个方面，总结工程项目BIM应用的策略，指导工程项目应用BIM进行项目管理，实现BIM应用能力与应用效益的提升；第三，以经典成熟度模型为基础，从工程项目生命周期、成熟度等级、BIM应用体系要素三个维度出发构建工程项目BIM应用成熟度模型，通过文献分析和专家访谈的方式总结出影响工程项目BIM应用能力的因素，设计工程项目BIM应用能力成熟度评价指标重要性调查问卷，研究实际工程管理过程中各个评价因素的重要程度及相互间关系，归纳出具体的评价指标，并给出各个指标具体的成熟度评分标准，再利用层次分析法进行权重分析和排序，形成完整的评价体系，以评价工程项目BIM应用的能力；最后，结合工程项目BIM应用现状和成熟度评价体系研究结果，给出BIM应用推广普及和BIM应用质量提高的实施建议。

      本文以提升工程项目BIM应用能力为目标，研究工程项目全生命周期的BIM应用策略，建立工程项目BIM应用成熟度模型及评价体系，为推进BIM在我国建筑业的深层次应用提供参考。

        The "14th Five-Year Plan" plan to expedite the integration of a new generation of information technology with various industries in-depth. Then, stimulate the expansion of digitalization, support digital industrialization and manufacturing digitization, encourage new technologies, new products, new formats, and new models, moreover, build new benefits in digital competition clear purposes. The building industry of China is encountering the throes of industry reformation. The de-bubble in real estate and the de-capacity of manufacturing has led to rapid dissolution in demand. Foundation corporations are suffering unusual demand for improvement and transmutation. The evolution of BIM (Building Information Modeling) has vigorously supported the digital construction of the architecture industry, infusing new vitality within conventional architecture manufacturing. Also, it is a powerful means for enterprises to upgrade their technology and innovate production methods and improve their competitiveness. Nevertheless, there are numerous problems in the development and reinforcement. How to efficiently implement BIM is the center of attention of major enterprises.

        According to the combination of internal and external BIM applications and study literature. This article explores the modern status and existing problems of domestic BIM applications based on actual engineering cases. Secondly, through the analysis of the whole process management objectives and needs of engineering projects, and discussion about the influence of different construction modes of engineering projects on BIM application, the strategies of BIM application of engineering projects are summarized from three aspects: BIM application point selection, BIM application organization construction and responsibility division, BIM application process and collaboration strategy design. To guide the application of BIM in project management of engineering projects, so as to improve the application ability and benefits of BIM.Third, according to the traditional maturity model, develop a BIM application advancement model for engineering projects. From the three dimensions of the project life cycle, maturity level, BIM application system elements, including review the impact projects within literature investigation and expert interviews. Factors of project BIM application capability, plan a questionnaire on the value of evaluation indicators for BIM application capability maturity of engineering projects. Furthermore, analyze the significance of each evaluation part in the actual project administration manner and the relationship between them. Moreover, review specific evaluation indicators. Also, give each the maturity scoring standards of the indicators. Then use the analytic hierarchy manner to carry out weight review and classifying to develop a comprehensive evaluation system to evaluate the ability of BIM application in engineering projects. In the end, consolidated with the study results of the BIM application status and maturity evaluation system of engineering projects. The implementation proposals for generalizing BIM applications and enhancing the quality of BIM applications are given.

        This study focuses on enhancing the BIM application ability of engineering projects studies the BIM application strategy from the complete life cycle of engineering projects. Also, builds the BIM application maturity model and evaluation system of engineering projects. On the other hand, provides source for enhancing the deep application of BIM in the construction industry of China.
