With the rapid development of China’s modernization, engineering construction needs more and more professionals with wide caliber and thick foundation. Therefore, the book covers the construction engineering, road engineering, bridge engineering and other professional fields.
    Civil engineering is a comprehensive subject which involves a wide range. Because its construction objects are all kinds of engineering facilities closely related to people’s life, production and other fields, the construction of civil engineering projects plays an important role in China’s engineering construction. At the same time, in the construction process of civil engineering projects, the types of construction technology involved are complex, the number of construction machinery and equipment, materials and personnel is large, and the construction period is generally long. If each project wants to be completed successfully, it must be supervised and controlled by professional project management team from various aspects, such as quality, progress, cost, risk, etc.
    This book introduces the content of civil engineering project management, and combines green development concept and BIM technology, discusses the application of green construction management and evaluation BIM technology in project management. As civil engineering construction and project management in China is still in the process of continuous development and improvement, it is necessary to constantly summarize in practice. There are inevitably some mistakes in the book, so readers are requested tocriticize and correct.

With the development of China’s economy and the progress of social material civilization, the HVAC industry is becoming more and more important in engineering construction and people’s life. The HVAC technology is becoming more and more advanced, and the equipment system is becoming more and more complex. At the same time, the social expectation of this specialty is also higher and higher. HVAC shoulders two missions: one is to provide high-quality artificial environment for human life, work, study, production and scientific research; the other is to reduce energy consumption and emission of harmful substances as far as possible. Especially in our country, the resource situation is grim, energy conservation and emission reduction has a long way to go. HVAC industry is a big energy consumer and has unavoidable obligations and responsibilities. In recent years, the HVAC industry is developing at an alarming speed, and the engineering design team is also expanding rapidly. However, to a large extent, the professional application technology still stays at the traditional level of high energy consumption and low efficiency. A large number of new designers are still continuing the traditional design methods, and even use the extensive design methods to deal with the heavy design tasks. Therefore, the task of HVAC is that the design concept needs to be updated, the designmethod needs to be improved, and the young designers need to be trained with advanced theory and technology.
    This book combines the theory of HVAC with engineering practice and combines traditional and modern design concepts and methods. This book has the value of discussion and exchange for the skilled designers of this major, and plays a role as the bridge from theory to practice for graduates and beginners of architectural environment and HVAC major.

In the long historical development process of human society, fire makes human gradually get rid of cold and darkness, ignorance and barbarism. It not only brings light and warmth to human beings, but also brings disaster and pain to human beings. The harm of fire is abominable. With the development of society, science and technology are highly developed and materials are extremely rich. However, the disasters caused by fire to human beings have not been weakened, but become more and more tragic. Due to the limitation of fire protection science and technology, at present, the occurrence of fire has its absoluteness, which does not depend on people’s will. In recent years, due to people’s weak fire safety awareness and careless use of fire, or violation of fire safety management regulations in life and work, it is common that disasters occur, resulting in the loss of people’s lives and social property. This kind of loss involves not only the suffering and death of people, but also the loss of property, and sometimes even the irreparable historical wealth. Many lessons are painful.
    Fire protection safety is an important part of national economy and social development, and an important guarantee for national economic development, social security and stability and people’s living and working in peace and contentment. With the development of politics, economy, science and technology in China, especially the development of social comprehensive technology and the change of social activities caused by it, the universality and complexity of fire problems have been greatly increased. Therefore, newer, more and higher requirements are put forward for fire protection management. Building fire protection safety management is also considered as a social problem, which has caused the people who are responsible for social public safety to think deeply and pay attention to it, and become an important part of social safety management.

Safe drinking water and good environmental sanitation are the necessary conditions for the healthy survival of human beings. With the development of our country, the problems of water supply and drainage become more and more important. 

Water supply and drainage engineering is the combination of all engineering facilities from water source to final disposal in cities or industrial enterprises. It is generally composed of water intake project, water purification project, sewage treatment project, sludge treatment and disposal project and water supply and drainage pipe network project. According to the different historical stages of engineering construction, it can be divided into new projects and reconstruction and expansion projects.
    Its construction and development is directly related to the improvement of the living standard and quality of life of urban residents and the expansion and development of industrial enterprises, but it is limited by the local natural resources, economic development level, cultural background and development history. With the acceleration of China’s urbanization and the development of industrial economy, the demand for domestic water of urban residents and industrial enterprises is increasing, and the requirements of water quality are also increasingly strict.
    However, China is a country with very poor per capita water resources. At present, the serious water pollution makes some water bodies lose their original functions and aggravate the tension of water resources. The shortage of water resources and the pollution of water environment have become one of the key factors restricting the sustainable development of human society and economy.

安全的饮用水和良好的环境卫生是人类健康生存的必需条件。随着我国发展的步伐逐渐加快，给水、供水和排水的问题显得越来越重要。
      供水、给水、排水工程是城市或工业企业从水源取水到最终处置的全部工程设施的组合体。一般由取水工程、净水工程、污水处理工程、污泥处理与处置工程等主要枢纽工程和给水排水管网工程组成，按照工程建设的历史阶段不同，可分为新建工程和改扩建工程。
      它的建设与发展直接关系到城市（镇）居民的生活水平、生活质量的提高与工业企业规模的扩大与发展，但是又受到当地自然资源状况、经济发展水平、文化背景与发展历史的限制。随着我国城市化步伐的加速和工业经济的发展，城市居民生活用水和工业企业用水需求量日益增加，对用水水质的要求也日益严格。
      但是，我国是一个人均水资源十分贫乏的国家，目前严重的水污染使得部分水体丧失原有的功能，更加剧了水资源的紧张状况。水资源的日趋短缺和水环境的污染已成为制约人类社会和经济可持续发展的关键因素之一。
