The construction industry is a significant part of every economy and that performance assessment holds the key to its success in national socio-economic goals. Successful Construction projects are closely related to contractor’s performance, where increases a suitable contractor the chances of satisfactory completion of a project in time, cost and quality specified. Contractors’ performance can provide robust benchmarks for contractors and help to identify ways towards performance improvement. Contractor performance can be defined by the level and quality of projects delivered to clients. he objective of this research work is to study evaluate contractor performance for construction projects, and how it can be employed technical grounds (The Method Of Multiple Criteria Complex Proportional Assessment) in the assessment of contractors Performance for construction projects, through the identification of criteria used to select the best contractor in terms performance as well as determining the list contractors of to choose the optimal contractor of these terms. For achieving the goal of the research its data collecting from the literature that addressed the factors Affecting Contractor Performance and method of multiple criteria complex proportional assessment (COPRAS), and finally personal interviews of engineers, contractors and owners qualified. The results of data analysis for the sample and then Rank Order Centroid method (ROC) and distinctive in their application showed that criteria of the quality of work, project management, technical knowledge, and timeliness of performance are the most important criteria for bilateral comparisons between contractors. Finally, and by calculating the relative importance, priorities of alternatives, and the benefit degree we find that the C1 has received the largest share of the benefit and importance. In the end, was a set of conclusions and recommendations of various aspects of the topic from accelerating the application of techniques of decision- making multi-criteria in the evaluation of contractors performance in addition to expediting the application of the systems proposed by the researcher for the evaluation of contractors performance.
