Abstract

According to Articles 155 and 168 of the Fifth Development Plan Law, any construction must be carried out with standard materials and its application by competent builders, and each building must be insured for ten years. Accordingly, the main purpose of this study is to investigate the barriers and problems affecting the standardization of construction materials in Lorestan province. The research method in this research was quantitative-qualitative (mixed) of exploratory type. In this method, the research team first developed a questionnaire including open-ended questions according to the objectives and questions of the research. After compiling the questionnaire and selecting the panel members, the interviews began. At this stage, fifty managers of material production centers, employers, experts of the provincial engineering organization, urban housing, standard administration, executives, and supervisors of construction projects were coordinated and interviews were conducted. The sample size was so saturated that the interviews in this section were saturated with fifty people and in the quantitative section it was a random sampling method in which three hundred and twenty-five manufacturers, consumers, supervising engineers, laboratory testers using Cochran's formula. Colleagues and contractors were examined. To collect information in this study, in-depth interviews, questionnaires, field observations, and experiments (obtaining the results of forty samples of tests performed by accredited laboratories by the General Directorate of Standards in the province and analyzing these tests based on existing standards) have been used.
