Abstract

Project delivery quality (PDQ) is a potential target of the construction team, which is working on enhancing this quality thru project stages: design and construction. A very important side of this work is study and research to investigate the critical factors affecting PDQ. Some former studies uncovered that the delivery methods: Design-Build (DB) and Design-Bid-Build (DBB) notably affecting PDQ. A study appraised the mentioned methods among several features, such as: time, communication, drawings …etc. This paper assumes that there are other critical features to be studied as it's believed to complete the appraisal among DB and DBB. The aim of this paper is to get sound results for deciding which of them will contribute in enhancing PDQ. The paper will run unstructured conversations with design and construction players: owners, consultants (design/supervision), and contractors. They were requested to provide their feedbacks regarding (6) chosen features among DB & DBB. Also, they were asked to justify their scores adding more details. Collected data was organized, tabulated, and analyzed, then discussed, and concluded.
