Toward the formation of parameters influencing the quality of low-rise residential buildings

Abstract

The construction industry occupies a significant place in the development of any country. The success level of construction projects largely depends on its quality. Poor performance of work leads to different losses. Effective quality management delivers customer satisfaction and value, reduces visible and less visible cost of poor quality. The article aims to identify the main parameters influencing the quality of low-rise residential buildings using expert opinion method. At the first stage, a literature review was conducted, which resulted in a list of 54 individual indicators of technical solutions that affect the quality of low-rise apartment buildings. These quality indicators have different degrees of influence. Experts identified indicators that have a greater impact on the comprehensive quality indicator. Then, the list was shortened up to 34 individual indicators. The survey was conducted in construction companies, research centers, and construction universities. The development of a comprehensive quality index contributes to the achievement of design decisions in construction of residential buildings. The methodological scheme of the study is shown. Using the method of exploratory factor analysis, all indicators were grouped into 7 groups. A conceptual measurement model is defined. Furthermore, a structural model to determine the influence weights of each individual indicator on the corresponding group of factors is shown.
