  abstract = {The Project Delivery System (PDS) selection is critical for the performance of construction  projects because it directly influences costs, efficiency, and stakeholder satisfaction. Despite its  importance, the proper PDS selection currently disregards identifying the most relevant  contractual factors and their relationship with value generation. This study compares the  characteristics and behavior of various PDS to address this issue. This paper uses a comparative  literature analysis of four PDS models, i.e., Design Bid Build (DBB), Design-Build (DB),  Construction Management at Risk (CM), and Integrated Project Delivery (IPD), to evaluate  their contractual factors and performance. The literature evidences that IPD may outperform  the other models, and despite the type of PDS deployed, the most frequently used contractual  factors are cost, time, communication, quality, and change. It is concluded that fostering the  use of collaboration and integration processes in the structure of the PDS drives performance  improvement and, hence, value generation. Further research must consider analyzing the effect  of emerging factors such as sustainability and digitalization.},
