Preface

BIM (Building Information Modeling) technology is a kind of digital tool applied in building planning, design, construction, operation and management in the field of civil engineering. BIM can integrate all kinds of information in the whole life cycle of buildings, share and transmit information, provide collaborative work for all parties in the whole process of construction and operation, provide technical support for industrial chain connection and industrial construction, and create conditions for improving quality, efficiency, energy conservation and environmental protection of construction industry.
      The emergence of BIM has led to a new revolution in the construction industry. It breaks through the bottleneck of traditional design methods, adopts three-dimensional parametric design concept, defines three-dimensional model with a new method, and greatly improves the efficiency of the whole process of construction project from initial design, construction to later operation management. The value of BIM technology has been recognized by the owner, designer, constructor, etc. It can be predicted that BIM technology will make great progress in the future construction industry and lead the construction industry to a new height.
     Although BIM technology plays a revolutionary role in the construction industry, it is a new thing after all. Relevant technicians, such as design, construction and operation and maintenance personnel, do not have a comprehensive understanding of BIM technology. Civil engineering students in colleges and universities know little about BIM technology, which is far from the technical requirements and development trend of the whole industry. In order to integrate with industry development and market demand faster and better, it is necessary to make a thorough and detailed review of BIM technology research and application in civil engineering. Therefore, in the process of writing this book, starting from the origin and development of BIM, it analyzes the bottleneck problems in BIM promotion process, and looks forward to the development trend of BIM, in order to show the latest trend and achievements of civil engineering development, and contribute to the development of civil engineering, software engineering, information engineering and other disciplines.
      Due to the limited level of editors and the rush of time, there are inevitably some shortcomings in the book. The author sincerely hopes that teachers, students and readers will put forward valuable opinions and give criticism and correction, with a view to further revision and improvement.

前 言

BIM（建筑信息模型）技术是一种在土木工程领域中应用于建筑物规划、设计、施工、运营以及管理等方面的数字化工具。 BIM 能整合建筑物全生命周期内的各种信息并进行信息的共享和传递， 为项目全过程各方建设及运营主体提供协同工作，为产业链贯通和工业化建造提供技术保障，为建筑业的提质增效、节能环保创造条件。
        建筑信息模型（Building Information Modeling， BIM）的出现，引发了建筑行业一场新革命，它突破了传统设计方法的瓶颈，采用三维参数化的设计理念，以一种全新的方法定义三维模型，使得建筑项目从初期设计、施工到后期运营管理的全过程效率都得到了大幅提升， BIM 技术的价值得到了业主方、设计方、施工方等的认可。可以预见 BIM 技术在未来建筑行业将取得长足发展，并引领建筑行业达到一个新的高度。
        虽然 BIM 技术对于建筑行业有着革命性的作用，但它毕竟是新生事物，设计、施工和运维等相关技术人员对它的认知还不够全面，高校土木类学生对这一技术也所知甚少，这一现状与整个行业的技术要求和发展趋势相距甚远，为了更快更好地与行业发展和市场需求相融合， 必要对 BIM 在土木工程中的技术研究与应用情况做深入细致的梳理。因此，本书在撰写过程中，从 BIM 的起源与发展出发，解析了BIM 推广过程中的瓶颈问题，并对 BIM 的发展趋势进行了展望，以期展现土木工程发展的最新态势和成就，为土木工程、软件工程和信息工程等学科的发展贡献绵薄之力。
       限于编者水平有限和时间仓促，书中难免存在不足之处，诚挚地希望广大师生与读者提出宝贵意见，给予批评指正，以期进一步修订完善。
