A construction project consists of many types of contracts. In the process of selecting the successful contractor after bidding, there will inevitably be fierce competition, which may lead to corruption or bribery. Even after signing the contract, during the period of settling the amount of the contract, bribery could occur. Such corruption could harm the development of the construction industry. It is, therefore, necessary to establish a strategy to prevent corruption by strengthening the transparency of the bidding process. In this study, to prevent corruption in the construction industry, a new service is proposed in which the successful bidder is selected by a professional third party, and the introduction of diverse delivery systems for construction projects and the invigoration of alternative methods of settling disputes are also proposed in this study.
