In recent years, with the continuous development of Chinas social economy, the level of science and technology is also constantly improving, and the development of the construction industry is also more rapid. However, in the construction process of construction projects, due to the influence of various factors, safety accidents occur frequently, causing great losses to peoples lives and property. In order to avoid the recurrence of accidents, it is necessary to strengthen the safety management of construction projects and take effective measures to prevent, control and deal with all kinds of safety accidents. This paper analyzes the main problems faced by the safety management of construction projects, and puts forward the corresponding countermeasures for these problems, in order to provide reference for construction enterprises. 展开更多

With the rapid development of social economy, the construction industry has also ushered in the demand of The Times, which intensifies the market competition in the construction industry. Construction enterprises should pay attention to technological innovation and application, control construction cost, ensure construction quality and efficiency, and help construction enterprises to achieve economic benefits. From the perspective of improving the level of construction technical management of construction engineering, this paper first analyzes the importance of improving the level of technical management, and analyzes and summarizes the current situation, and finally provides feasible measures for it, so as to bring some inspiration and reference for readers. 展开更多
