This paper proposes a radical change in industry practice that will improve the quality of the construction process and the levels of customer satisfaction derived from it by evaluating the quality performance of the contractor. An alternative theory is developed of what constitutes quality, client satisfaction, performance, and their interrelationships in the context of the construction industry. It should be noted here that the term construction client includes both the owner (i.e. the agency or organization funding the project) and the end-user of the construction (i.e. the general public). A comprehensive view of construction quality is proposed that deals with both the service (as received by the owner) and product (as received by the end-user) aspects of the construction project as well as the corporate quality culture. Such a dissection of construction activity facilitates developing strategies to define, operationalize, measure and improve construction quality. A frame4 work for the assessment of a contractor's quality performance is established. This involves gathering a list of contractor quality performance (CQP) indicators that are derived from various quality-related practices of the contractor at the corporate and project level. Finally, a contractor quality performance (CQP) evaluation model is introduced that can be used in a contractor prequalification and/or selection system. The CQP indicators are operationalized within the theoretical framework of the CQP evaluation model.Contractor Quality Performance, Quality Control, Quality Assurance, Prequalification, Contractor Selection,

To assess quality of health services in Zanjan health centres based on clients' expectations and perceptions. The study was conducted by using service quality (SERVQUAL) scale on a sample of 300 females, clients of health care centres in the district of Zanjan, selected by cluster sampling. The results indicated that there were negative quality gaps at five SERVQUAL dimensions. The most and least negative quality gap mean scores were in reliability dimension (-2.1) and tangible (-1.13) respectively. There was statistically significant difference between clients' perceptions and expectations mean scores at all of the five service quality dimensions (P<0.001). The negative quality gap level in health service dimensions can be used as a guideline for redistribution of resources and managerial attempts to reduce quality gaps and improvement of health care quality.
