Quality management has been one of the research focuses in construction management for at least two decades and extensive literatures have been written in areas related to the quality of construction works. Most agree that a change in culture, or a creation of a quality culture, is the key to the success of any quality initiatives made by contractors. To achieve cultural change, one must be able to measure the magnitude of any change, positive or negative, against a predetermined benchmark. In other words, the existing quality culture of a contractor must first be audited so that it can be used for further reference. Through the use of a Quality Culture Auditing (QCA) questionnaire, this paper develops a pragmatic tool enabling construction contractors to measure the quality culture quantitatively using a scoring system. A total of 90 employees from 30 contracting firms completed the QCA questionnaire and the scores obtained were analysed. Parametric studies using company sizes and working levels of employees were also performed. The results indicate that QCA can be used to reflect the existing quality culture of a construction contractor, who can hence make improvement on the areas which are weak as indicated by the QCA. © 2010, Taylor & Francis Group, LLC.
