건설자재 현장품질관리 지침 개발을 위한 실태조사

The purpose of this study is to ensure an amicable material quality control in the construction site through investigating a process which can impact the construction material quality. For it, a worker interview and questionnaire survey was conducted through a direct field visit. The visited construction sites are composed of 79% construction site and 21% engineering site. As the respondents of questionnaire survey, the quality control workers were 72% of total respondents. Next, the construction worker, handymen, field representatives and others formed 7%. The interview with the quality control staff was conducted with the items including the construction site quality control guide, incoming inspection and material management. Through this survey, the problems of quality control by progress phase were derived. It could be known that the management and measures by each phase were urgently required. It also was indicated that a selection of low-priced material caused by low price bidding could badly impact the construction and safety. Also, in relation to the opinions such as the insufficient quality control and heavy work-load, the improvements are required. For the effective quality control in the construction site, the material quality control procedures suitable for the phase of construction progress must be presented in the present quality control. Also, the standards for it need to be established.
