Building Information Modeling Application in Design_Bid_Build Projects
Since, Design-Bid-Build (DBB) was the most popular project delivery method at the beginning of previous decade regardless of all its shortcomings, applying new advanced tools can compensate disadvantages of this method. Recently, advanced technology in construction management called Building Information Modeling (BIM) became popular among construction industry. Although, effects of BIM on different aspects of alternative project delivery methods were considered in literature, but adequate efforts on evaluating BIM application in DBB projects have not performed yet. This research aims to investigate effects of using BIM in DBB projects. For this reason, a questionnaire survey was conducted among construction industry practitioners in Iran to evaluate their opinions about using BIM in DBB projects. To assess reliability of questionnaire survey results, a single case was studied to compare cost and time of DBB projects in case of using BIM with real project which was executed without using BIM.
