Empirical Analysis of the Relationship between Project Delivery Method on Project Performance in the Yemen Construction Industry

This empirical paper analyzed the relationship between project delivery methods on project performance within the Yemen construction industry (YCI). This research incorporated two distinct project delivery methods (PDM) namely the traditional Design-Bid-Build (DBB) and Design-Build (DB) and gauging project performance (PP) through the lens of the triple constraints (time, cost, and quality) as the criteria for measuring success. A conceptual model was theorized and operationalized in a survey of 375 project managers and consultants from two Yemeni governorates, Aden and Hadramout. The questionnaire employed a 5-point Likert Scale. Subsequently, the data were evaluated using multivariate regression. The empirical findings revealed a significant relationship between the choice of project delivery method and project performance. Thus, exerting a positive influence on project success. This study contributes to the existing body of knowledge in two significant ways. First, by scrutinizing the dynamic mechanisms through which project delivery methods impact project performance. Secondly, offers valuable insights for decision-makers in the Yemeni construction industry (YCI) to plan their objectives and achieve the requisite project performance levels.
