Thus it puts forward higher requirements to building construction enterprises, urging them to study scientific quality management theories and methods and put them into use, to improve the quality of construction management level and then build more high-quality buildings. This paper briefly analyzes the present situation of LE construction quality management, and mainly expounds the application of quality management methods with the computer-aided in LE engineering construction, so that LE engineering construction enterprises can improve quality management efficiency and achieve sustainable and healthy development of construction engineering industry.

New requirements for technical acceptability of construction products as a component of the construction quality assurance system

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.

A consortium blockchain system is designed to support construction quality management in which participants’ information permissions and lifecycle are discussed. Additionally, this study presents in detail the consensus process that aims to address the problem of information fraud. The automated compliance checking based on smart contracts is presented as well, aiming to assure that construction products meet regulation requirements. Finally, an example of the consortium blockchain network is visualized to validate the feasibility of blockchain-based construction quality information management. The research shows that blockchain can facilitate mutual trust in construction quality management by providing distributed, encrypted, and secure information records and supporting automated compliance checking of construction quality.

Assessment and quality management of construction and installation works

The work is devoted to the study of procedures for assessing the quality of construction and installation works. It is emphasized that there are significant differences in the parameters for assessing the state of an object and a process. When the process is flowing, it most often requires smoothness, the absence of spasmodic changes. Violation of these requirements affects the technological process final result - the finished product’s quality. It was revealed that the quality of the process can be determined by decomposing it into the operations and evaluating deviations in synchronization, coordination, technological modes and the costs of their implementation. However, the sequentially carried out processes, as follows from the theory of metasystems, can be evaluated by the readiness of the next operation. In this regard, the task of optimal availability control is further posed and solved.
