In order to improve the quality control system of construction and installation works (CIW) in Vietnam, it is necessary to identify the factors that may affect the system. There has been carried out an investigation with survey questionnaires in regard of people engaged in construction industry in the country, and there were received 184 responses. More than 84,2 % of respondents have extensive experience in the field of construction (over 10 years), almost all respondents are directly involved in the production process of construction (91,3 %).The results of the survey were processed using the factor analysis method, and five of the 39 initially observed variables were excluded. The remaining 34 variables were left as relevant to the CIW quality control system and are reduced to six groups of factors: people, documents, partnerships, resources, processes, goals.
