This study aims to identify the critical success factors (CSFs) in the implementation of the public–private partnerships (PPPs) in the United Arab Emirates’ (UAE) affordable housing sector.
A questionnaire survey was conducted to assess 17 CSFs for PPP projects derived from previous international and local studies. The collected data were analyzed using the relative importance index technique to establish the most significant factors based on feedback from 48 respondents from the public and private sectors.
The most identified CSFs were good governance, government guarantees, commitment and responsibility of the public and private sectors, favorable and efficient legal frameworks, political support and stability, and demand for and the debt-paying ability of the project.
There has been rapid momentum in the UAE and other Gulf Cooperation Council (GCC) countries towards engaging the private sector in the provision of infrastructure and housing after increased pressure on government budgets and falling oil prices. Thus, this study encourages strong consideration of the highest-ranked CSFs in the absence of any prior experiences or studies. On a broader scale, these CSFs are an effective policy tool for the GCC countries, which share similar contexts.
This paper represents the first empirical study in the GCC region and the UAE on the CSFs for PPPs in affordable housing, which is experiencing growing demand in the region to overcome the large deficit in housing supply.

A bridge network is a major capital asset that requires continuing investment in order to maintain the network within acceptable limits of safety and serviceability. Ranking and prioritizing procedures have been widely used by several departments of transportation to select bridges for intervention and to distribute the available funds among competing projects. The available ranking and prioritizing procedures have various drawbacks, and an improved, rational ranking and prioritizing procedure is needed. The paper aims to address these issues.
The requirements and characteristics of an innovative ranking and prioritizing method are identified during interviews with professionals involved in bridge management. Based on these requirements, multi‐attribute utility theory (MAUT) is selected to develop the method. A technique to develop utility functions based on the analytical hierarchy process (AHP) is discussed. A hierarchy structure that captures the decision‐making elements is presented. A case study is used to demonstrate the applicability and the validity of the proposed ranking method.
The research findings have identified the decision objectives and the criteria essential to rank and prioritize bridge projects, and these are included within a framework to rank and prioritize bridge projects while incorporating experts' input in the process.
The proposed framework includes weights for the various objectives and recommends utility functions to evaluate the different attributes. In addition, the framework provides flexibility to adjust the weights and to modify the utility functions to reflect network‐specific characteristics. This method can be used by departments of transportation to rank bridges in a network, even incorporating conflicting criteria, and it can be integrated within an already implemented bridge management methodology.
Ranking and prioritizing projects are essential steps in bridge management. Current methods for ranking and prioritizing bridge projects are associated with various drawbacks. This paper proposes an innovative ranking method for bridge networks, based on MAUT. This theory provides flexibility for the decision makers in expressing their degree of satisfaction with each bridge attribute.
