The analysis and generalization of theoretical approaches to the formation of the construction quality system, the generalization of the legislative and regulatory framework for quality control in construction. Analysis of the theoretical prerequisites for the formation of quality control of construction revealed that the digital transformation of construction is an integral part of the development of modern society, a prerequisite for changing the system of construction, including control, quality assurance and evaluation of construction processes, works, materials, products and structures. It was found that the quality in construction is directly affected by the following factors: quality and completeness of design documentation; the possibility and obligation to comply with legal requirements; quality of construction processes and works, strict compliance with the requirements of technology and construction organization; quality of construction products and structures; technical ability to provide a given level of quality with the help of machines, mechanisms, means of small mechanization, etc .; the level of qualification of management staff, workers and line ITP. The quality system itself can be presented in the format of a "black box", where the factor will be named at the entrance, and at the exit - buildings and structures that meet a given level of quality throughout the life cycle of the object. It is proposed to consider the construction quality management system in the form of a multicomponent formation and at the same time a dynamic environment, which is constantly changing under the influence of external and internal factors and has a high degree of scholasticism and uncertainty. With the introduction of digital technologies in the organization of construction, including VIM modeling, use of artificial intelligence, cloud services for information storage, quality control tools that can be performed without human intervention, such as drones, robotic elements, surveillance cameras and others, the construction quality assurance system has to change, taking into account the realities of time. Therefore, the system of quality formation in the article is proposed to be considered throughout the life cycle of the object - from pre-project research to liquidation. This will, in contrast to existing approaches, not only combine into a single system all the components of assurance, evaluation and quality control, which are used at the level of all participants in the construction, but also to ensure integrated process management.

Highway bridge engineering is an important part of modern transportation system. It has a great effect on the devel-opment of modern society. Therefore, it is very important to ensure the construction quality of highway bridge engi-neering. At present, there are more and more construction technology quality control issues in the construction of high-way bridges should be given enough attention. The problems should be actively found out and effectively solved to improve the quality of life, while promoting China development of infrastructure construction. This paper analyzes the quality control strategies in the highway bridge construction.

At this stage, China’s economy develops better and better. The requirement for the construction of urban infrastructure is also getting higher and higher. As the key of the foundation construction, the highway bridge can effectively guarantee the safety of the transportation industry and the development of the future.In the process of highway bridge construction, the construction quality is the key point of the control, high construction quality can maximize the service life of the highway bridge, ensure the safety of the vehicle.Therefore, how to effectively control the construction quality of highway bridges effectively has become the urgent task. In view of this, in this paper, by analyzing the common quality problems of highway bridge, and summed up the reasons affect the construction quality, and find out the corresponding measures to solve the problems, hoping to provide some help for highway and bridge construction.

<p>Mechanical and electrical installation is a very important construction technology in construction engineering. From the perspective of the construction unit, whether the installation technology and procedure are scientific and reasonable will have a direct impact on the final quality of the project, and it is also closely related to the personal and property safety of the residents. Based on this, construction organizers should construct and perfect a standardized installation construction quality management system, clarify management regulations, and control key technical points, so as to comprehensively improve the quality of electromechanical installation projects and improve the project qualification rate. This article will describe the construction technology and quality control strategy of electromechanical installation engineering, aiming to lay a theoretical foundation for the improvement of engineering qualification rate and construction quality.</p>
