Public is the largest client in many countries. Public agencies acquire good, service and constructed facilities through the procurement. Most of the public procurements are completed later than the estimated times or even canceled due to the various reasons. Public procurement processes can be improved by using statistical or non-statistical process improvement methods. A review of the construction management literature reveals that process improvement methods are commonly focused on construction operations. Various process improvements have been proposed to improve effectiveness and efficiency of construction operations. Yet improving the tender evaluation process of construction projects is an unexplored research area in the construction management literature. The objective of this study is to analyze the tender evaluation process of public agencies and measure and in turn evaluate the adequacy of this process by using the process improvement methods. The study presented in thesis is based on two process improvement methodologies: (1) Define-Measure-Analyze- Improve-Control (DMAIC) and Process Capability Analysis (PCA). Public procurement processes performed by public agencies (i.e., state universities) are investigated. Tender evaluation processes of public agencies are studied based on criteria: (1) number of participants and (2) estimated construction cost. The research findings reveals that (1) the most time-consuming stage in the tendering process is the tender evaluation stage, (2) the tenders having higher estimated construction cost and more participants have longer tender duration and (3) the process capabilities of public agencies based on number of tenderers and estimated construction cost appear to be poor. The poor capability indices of public agencies suggest that immediate managerial actions should be taken to improve tender evaluation process in public agencies.
