With the development of China’s economic construction and society, as well as the continuous emergence of new science and technology, the demand for surveying and mapping results is increasing. Surveying and mapping projects show the characteristics of large production scale, high investment amount, high technical requirements, complex construction process and so on. In order to ensure that the surveying and mapping project is completed on time and with high quality, it is difficult for the investor to supervise and manage the project. With the continuous improvement of China’s laws and regulations, the deepening of socialization, specialization, standardization and normalization of engineering supervision work, and the continuous improvement of engineering supervision system, more and more investors choose to supervise and manage surveying and mapping projects with the help of social professional forces.
         In the process of engineering project construction, the level of engineering measurement is the most direct factor affecting the quality of engineering project construction. High level and high quality of engineering measurement is of great significance to ensure the smooth progress of engineering project construction and improve the quality of engineering construction. In order to effectively improve the technical level of engineering survey, we should strengthen the application of advanced surveying and mapping technology, such as digital surveying and mapping technology, whose technical advantages are very prominent. When applied in engineering survey, it can provide strong technical support for engineering survey, ensure the efficient development of engineering construction projects, and improve the quality of engineering construction. Compared with traditional surveying and mapping technology, digital surveying and mapping technology is more accurate and faster. The accuracy of measurement results is very important for a project, which is related to the quality of a project. Therefore, digital surveying and mapping technology not only improves the efficiency of Surveying and mapping in engineering construction, but also helps to improve the quality of the project.

In recent years, with the increasing investment in power infrastructure projects in China, we must implement effective management of complex infrastructure business through information system. The enterprise resource planning (ERP) is an advanced management idea, which focuses on organization model, business process, enterprise rules and regulations, information technology, etc.
       Power engineering management is an important part of power enterprise management in China, and plays an indispensable role in the power system. The management of electric power project has an important influence on the economic benefits of project investors and construction enterprises. In recent years, with the implementation of China’s sustainable development strategy, the construction of power engineering projects is gradually increasing. For China’s power grid, under the premise of ensuring the improvement of the power grid system and power supply quality, the reasonable cost control can not only improve China’s economic level, but also help China’s power grid system to be more mature and perfect. At present, the high project cost is largely due to the unscientific and unreasonable management mode of power grid system. Therefore, if we want to control the project cost, we should start from the perspective of management.

The concept of urban design was introduced into China in the 1980s, which has aroused the general concern of the planning circles. Due to the fact that urban design has not obtained the legal status in our country, and the country has not given a clear positioning for urban design, leading to the current situation that the domestic theoretical circles hold different opinions. In the practice of specific projects, the contents and achievements of urban design are also multifarious, lacking a unified understanding. China’s urban planning system originated in the early days of the founding of the People’s Republic of China has some disadvantages in the process of urban construction after the Economic Reform and Opening up. In recent years, it has also been concerned by the planning circles. The development of urban design work can just solve some of the problems, which is in line with the objective requirements of the new era of urban construction.
      This book mainly studies the origin and development process of modern urban planning and urban design; the development status of modern urban design theory and practice at home and abroad; the urban planning system and the current urban planning compilation in China and its shortcomings. On this basis, it discusses the relationship between urban planning and urban design and their respective emphases, and establishes the principles corresponding to each stage of urban planning in China. The book emphasizes the idea that urban design work should run through all stages of urban planning, and makes a preliminary study on the tasks, types and contents of urban design work in each stage.
