BOT Viability Model for Large-Scale Infrastructure Projects

The key to a successful implementation of a build-operate-transfer (BOT) infrastructure project is in-depth analysis of all aspects related to economic, environmental, social, political, legal, and financial feasibility of the project. For these reasons, the analysis of the project feasibility decision needs a technique to include the qualitative decision factors that have a strong impact on the project. This paper aims to introduce a decomposed evaluation model developed to assess the most common significant decision factors that strongly affect the feasibility of BOT projects. The paper describes the viability decision factors that were identified and screened with the assistance of a group of industry experts. This analysis yielded 21 significant factors that would have a certain impact on the feasibility of any BOT project. These factors were classified into three relative categories forming the structure of the suggested project viability model. This model presents a new approach, based on the analytical hierarchy process technique, to evaluate the relationships between decision factors related to project feasibility determination. The new approach has been validated by information obtained from three case studies of BOT projects. The proposed approach to project feasibility evaluation aims to increase the decision maker’s ability to determine the factors contributing the most to the viability to the BOT project at hand.

Problems Facing Parties Involved in Build, Operate, and Transport Projects in Egypt

One of the newest financial schemes for environmental projects is the Build, Operate, and Transfer (BOT) concept, which is being used increasingly worldwide as a project delivery system by which governments obtain the infrastructure projects by private sector after a concession period free of charge. In the Egyptian environment up to now, promoters and investors have had many fears toward declared projects. This study aims to investigate the potential for implementing the BOT system in the Egyptian environment. This can be achieved by giving a clear view of BOT and of its problems, risk areas, and features, pertaining to the Egyptian environment, in order to maximize the benefits and minimize the risks as much as possible. The collected data was analyzed based on actual implementation in Egypt. This involved the following: (1) An overview of the critical success factors in order to achieve a BOT project; (2) an analysis of results obtained from questionnaires seeking to determine the possibility of occurrence of the different risk factors in the Egyptian environment, and their ranking; (3) a comparison between the questionnaire results and the actual risks from requests for the proposal of locally advertised projects; and (4) a determination of the missed critical success factors in the Egyptian environment. The main conclusion of this study is that three critical success factors are essential for the success of BOT projects in Egypt: (1) Picking the right project; (2) competitive financial proposal; and (3) special features of bid.
