Statistics show that one third of all contract disputes in the construction stage is related to change of design, and that 80% of disputes over change of design are due to design flaws. Any flaws in the design can increase the risk of failure during construction, which aims to “be on schedule, achieve the desired quality, stay within the budget, be safely carried out, meet environmental and ecological protection requirements, and promote smart green buildings.” It is necessary to actively implement a quality management system during the design stage to continuously improve the quality of design and elevate the level of quality management. Only then can the requirements of various laws and regulations be met, and will the client gain a satisfactorily designed product. This will also make the subsequent construction stage more reasonable and efficient. To effectively improve the quality of design, this study first summarizes causes of design flaws by finding design flaws identified in past construction inspections, design related disputes in the construction stage, issues encountered during operation and management, and difficulties with maintenance and repair. A questionnaire survey is conducted to learn the current status of design flaw management, which is further analyzed for verification and recommendations. Finally, this study conducts a questionnaire survey on two execution strategies, namely establishing a professional review mechanism and quality management plan, to obtain opinions on their feasibility. This study then plans a professional review mechanism and compiles an outline for design quality management plans, so as to improve the quality of designs with respect to execution. Findings of this study are as follows: 1. The appropriate quality management system and operating guidelines must be included in the contract, so that the owner and contractor can find the shortest path to standardization, reduce deviations, and improve knowledge accumulation and experience sharing, which will further improve design management ability; 2. A review unit should be responsible for overseeing the design stage, and the owner should establish a design review mechanism; 3. Requirements on the quality of design should be specified in the contract to provide a basis for designing public works, so that the outcome will meet all regulations and standards related to operating methods and procedures.
