Comparative Analysis of Design-Bid-Build and Design-Build from the Standpoint of Claims

Abstract

The traditional project delivery method known as design-bid-build (DBB) has been known to give rise to adversarial relationships amongst and between project participants, and, as a result, litigation amongst and between such parties. It has been suggested that the design/build (DB) project delivery method has reduced the number of claims from the contractor to the owner since the designer is now a member of the contractor's project team. It is also suggested that the number of claims from the owner to the design-builder has been increased as a result of owner's dissatisfaction with the actual performance of the project. This research conducts a literature review and interviews with experienced project participants to gather information on DBB and DB with respect to claims. The key categories of claims and the underlying influential factors leading to those claims are identified. Qualitative data analysis is performed to determine how the DB approach has affected the typical influential factors leading to claims under the DBB model. This paper presents the result of the data analysis both in a framework and textual format.
