Abstract
Selecting the appropriate delivery approach holds a huge significance level, especially in sustainable construction projects, which exhibit unparalleled attributes compared to traditional counterparts. This paper introduces a novel decision support model aimed at assisting owners in this crucial nomination process. Critical review analysis was used to identify 36 important nomination factors for project delivery methods and categorized into traditional and sustainability-specific factors. In order to determine how well typical delivery methods—Design-Bid-Build (DBB), Design-Build (DB), and Construction Management at Risk (CMR)—meet the nomination factors, a poll was subsequently sent to construction experts in the United Arab Emirates. Paired analyses of the three delivery systems were performed using the Analytical Hierarchy Process. The results showed that DBB, the traditional delivery technique, is not up to the increased needs for integration and collaboration in sustainable construction projects. Alternative delivery techniques, like CMR and DB better meet these needs. Three functions make up the suggested decision support model: screening of nomination factors, evaluation of project delivery methods, and strategic alignment of project goals and project delivery methods nomination factors. Users of this model can alter the weights assigned to the nomination factors that are essential to accomplishing the objectives of their green construction projects. It also offers an extensive set of nomination factors, enabling choice determiners to formulate a convincing argument for pinpointing the best delivery method for their green construction project.
