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.

       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。

The construction industry plays a pivotal role in the development of the national economy and the four modernizations. In terms of investment, the state funds for building installation projects account for about 60% of the total capital construction investment. On the other hand, the development of the construction industry plays an important role in promoting other industries. It consumes a large amount of steel, cement, local building materials, and other products of the national economic sector every year. At the same time, the products of the construction industry serve the people’s lives and other national economic departments and create the necessary conditions for the expansion and reproduction of various sectors of the national economy. The national income provided by the construction industry is also at the forefront of various sectors of the national economy. At present, many countries have listed the construction industry as a pillar industry of the national economy. In China, with the development of the “four modernizations” construction and the in-depth implementation of the reform and opening-up, the pillar role of the construction industry is increasingly being played.
     BIM is a new thing in the construction industry. In the past ten years, through continuous promotion and practice, people have reached a consensus: BIM has led and will continue to lead the information revolution in the construction field. With the gradual deepening of BIM applications, the traditional architecture of the construction industry will be broken. It will be replaced by a new architecture dominated by information technology. The application of BIM has completely broken through the technical scope and will become a powerful driving force for the leading construction industry to make changes. This is an opportunity and a challenge for the entire construction industry.
     From the application practice of BIM in recent years, BIM application is not simply the application of new software. To be successful in BIM application, it needs a set of systems, plans, and methods, and the execution team is matched with it. The construction industry practitioners who apply BIM also need to have relevant knowledge of BIM to apply BIM better, and more maximize the value of BIM applications.

建筑业在国民经济发展和四个现代化建设中起着举足轻重的作用。从投资来看，国家用于建筑安装工程的资金，约占基本建设投资总额的 60%。另一方面，建筑业的发展对其他行业起着重要的促进作用，它每年要消耗大量的钢材、水泥、地方性建筑材料和其他国民经济部门的产品，同时，建筑业的产品又为人民生活和其他国民经济部门服务，为国民经济各部门的扩大再生产创造必要的条件。建筑业提供的国民收入也居国民经济各部门的前列。目前，不少国家已将建筑业列为国民经济的支柱产业。在我国，随着“四化”建设的发展，改革开放政策的深入贯彻，建筑业的支柱作用也正日益得到发挥。
      BIM 作为建筑业的一个新生事物，在近十年中，通过不断的推广与实践，人们取得了一个共识： BIM 已经并将继续引领建设领域的信息革命。随着 BIM 应用的逐步深入，建筑业的传统架构将被打破，一种以信息技术为主导的新架构将取而代之。 BIM 的应用完全突破了技术范畴，将成为主导建筑业进行变革的强大动力。这对于整个建筑业而言，是机遇，更是挑战。
     从近年来 BIM 的应用实践来看， BIM 应用并不单纯是新软件的应用。 BIM 应用要取得成功，需要有一整套的体系、计划、方法，并且执行团队与之匹配；应用BIM 的建筑业从业人员也需要掌握 BIM 的相关知识才能把 BIM 应用得比较好，并且通过系统集成更大限度实现 BIM 应用的价值。

At present, the development of railway construction in China is rapid. The number of construction projects related to the existing line is increasing year by year. The construction of the existing line has the characteristics of great interference between construction and transportation, great difficulty in construction organization, complex technical scheme, high risk of safety and construction period.
    First, the demand for overall planning of transportation and construction is getting higher and higher. Hub transformation and large-scale station transformation often lead to the whole body, and even need to adjust the transportation organization in a wide range to cooperate with the construction. Therefore, the construction scheme should be closely combined with the transportation organization, considered as a whole, and provided conditions for each other, otherwise it is difficult to implement.
     Second, the construction is more and more difficult and the construction period is tight. First, with the large-scale operation of high-speed railway, strict control is required for settlement and deformation, and the requirements for track accuracy are higher and higher; second, the construction environment is more and more complex, with the gradual improvement of the road network, the effective construction space of the new line into the existing hub is smaller and smaller, and the construction is more and more difficult; the third is that the research period of the early scheme is often long, the coordination work in the later implementation process is many, the procedure is complex, and the construction period is generally tight.
    Third, the construction safety pressure of the existing line is large. The safety of railway operation is an eternal theme, and the pressure of construction safety is great.
    In view of this, the author has compiled the construction of the existing line, hoping to provide help and reference for the builders engaged in the construction of the existing line. This book can be used by management and technical personnel engaged in railway construction, operation safety management, construction, design, supervision and so on. It can also be used by teachers and students in colleges and universities for construction organization design or construction course teaching case analysis.
      Due to the limited level of editors and the short time of writing, there are inevitably defects in the book. Readers are welcome to give advice and correct it.
