This research aims to represent a conceptual model aimed at evaluating the performance of Value
Engineering Workshops (VEWs) in Iranian construction projects, given contextual and special conditions of
the country. For this purpose four steps were taken; 1-identification of performance criteria for value
engineering in construction projects based on literature. 2-application of factor analysis for extraction of main
criteria of the performance assessment and recognition of the performance assessment concepts. 3-use of AHP
method for comparison of factors. 4-evaluation and ranking of three VEWs. Through a questionnaire and using
factor analysis finally 5 constructs and 27 important measures for performance assessment of VEWs were
identified. The second questionnaire was designed based on AHP method in order to prioritize 3 VEWs given
the criteria identified in first phase of the research and also ranked the same constructs. 4 experts that were
working in 3 workshops answered this questionnaire. The results of analyses through Expert choose software
showed the order of prioritization of workshops as follows; workshop 3 ranked 1, workshop 2 ranked 2 and
workshop 1 in 3rd place. Based on the proposed model, performance evaluation can be done on staff and
designers of VEWs and the most important factor affecting workshops can be identified and analyzed.
