In order to improve the construction quality, they will formulate corresponding construction management system to optimize the project management and construction. With the continuous development of society, it is necessary to innovate the construction of projects, so as to promote the deepening reform of urban construction projects in our country and promote the all-round development of urban construction projects.展开更多

In the process of project construction, project management is related to project quality and project cost. The construction unit should pay attention to the project management, strengthen the control of the construction process, put forward targeted control countermeasures, optimize the project management effect, improve the overall construction quality of the project, and promote the sustainable development of the construction industry in our country. Based on this, this paper studies the construction process control in urban construction management for reference.展开更多

At present, under the new economic development situation, China's civil engineering construction is facing new challenges and opportunities. At the same time, with the continuous improvement of the level of science and technology, a large number of advanced technologies are also constantly infiltrating into the field of construction and civil engineering, which has greatly changed the structural mode of construction and civil engineering, and has significantly improved the efficiency and quality of its construction. Therefore, in order to truly ensure the benefits of building civil engineering and promote its continuous and stable development, it is necessary to strengthen the control of its technology in order to improve the quality of the whole building. Based on these problems, the paper gives some suggestions for future research.展开更多
