According to previous research, the reason why Design-Build(hereinafter ¡°DB¡±) outperforms Design-Bid-Build(hereinafter ¡°DBB¡±) in terms of cost is due to less change orders(hereinafter ¡°COs¡±). However ; if biddropping was low for DBB resulting into increasing COs ; then it would be wrong to conclude that DB is superior due to less COs. Therefore ; in order to confirm such misjudgment ; the attempt to comprehensively analyze biddropping ; COs and delivery method was made as previous methods had analyzed either the relationship between delivery method and COs ; or biddropping and COs. This research uses path analysis ; which simultaneously compares effect sizes on COs according to delivery method and biddropping based on the project type ; and validated the mediator effect. The research proved that DB outperforms DBB due to less COs cannot be validated as biddropping caused a mediator effect by intervening between the delivery method and COs for specific project types. Therefore ; the mechanism of delivery method acts on COs through biddropping was established. Also ; the identity of biddropping was investigated in a different perspective from previous research. Based on this result ; this research is expected to help determine a delivery method by considering the mediator effect of specific projects and evaluate performance. |
