Existing studies on the performance evaluation by the delivery method generally indicate that the design build (DB) method is superior to the design-bid-build (DBB) method in terms of construction duration, cost, and quality. As opposed to the performance of construction duration and cost, where quantitative evaluation is relatively possible, most performance evaluations of quality are based on interviews with the owners. Therefore, this paper aimed at evaluating the level of design performance to conduct a quantitative evaluation on the performance of quality. To achieve this goal, this paper analyzed the impact of delivery methods on design performance in terms of the quantitative evaluation based on the case studies analyzing construction drawings and specifications of public multifamily housing projects delivered through the DB and DBB methods since 2000. The Delphi and analytic hierarchy process methods were used to develop objective standards and contents for evaluating the design performance. An analysis of variance test was conducted to analyze which delivery methods would have an effect on the design performance. Construction industry practitioners can use the results of this study in selecting a delivery method appropriate to the project characteristics.
