This study is a basic research on looking onto bringing performance warranty contract into the country, to consider the usage in architecture which it is usually used on road pavement in developed countries. The study will also apply performance warranty contracts on public private partnerships through examination and analysis of various matters which will lead to globalization of the korean architecture industry, the increase of quality of result, better convenience for the orderer, the decrease of cost, and the acceleration on research for technical development.

Existing specifications of road pavement require contractors to meet only materials and construction conditions regardless of pavement life. There are limitation of developing road pavement technology and possibility causing dispute between ordering organization and contractor with this type of specification. Research efforts to introduce performance warranty contracting are in progress in the field of road pavement to improve the problems. The performance warranty contracting gives the contractors opportunity to select materials and construction methods as they like. But they should satisfy a certain level of performance during a given period. The performance indicator and threshold value of pavement which are main elements of the warranty specification should be defined first to introduce the performance warranty contracting successfully. In this study, the performance indicator, threshold value, and warranty duration of asphalt pavement were investigated by reviewing literatures on performance warranty contracting of some states of the US. Major distresses influencing the performance of the asphalt pavement were investigated at 24 national expressway lines and national highway lines in 16 regions, and the data were analyzed to be compared to the cases of the US. Development of rational performance warranty specification for domestic asphalt pavement is expected based on the research results.

This study has been carried out in order to observe the status of performance warranty contracting system currently being implemented at the advanced countries including Europe, U.S.A., and Japan, review the introduction feasibility and possibility. For this purposes this study has surveyed the concept and necessity of performance warranty contracting system as well as the status of domestic performance warranty contracting system. Especially the application environment for the performance warranty contracting system of Europe, U.S.A., Japan and Korea in terms of maintenance guarantee liability system, performance warranty regulations for design-build contracting system, selection method of successful bidder, performance warranty means, project contracting system including maintenance cost, and specifications and contract conditions for performance warranty system have been comparatively evaluated. And introduction methods of performance warranty contracting system were suggested.

Recently, researches on the performance warranty contracting has been going on to improve construction quality in road pavement area. The performance warranty contracting gives construction companies opportunity to select materials and methods freely while asks them to maintain a certain level of performance during a given period. To introduce the performance warranty contracting in Korea, lots of research results on performance indicator and threshold value of asphalt pavement have been made to be included in the warranty specification. However, research effort on the performance indicator and threshold value of concrete pavement which is commonly constructed in expressway and national highway has not been enough. In this study, the warranty duration, performance indicator, and threshold value of the concrete pavement were investigated by reviewing literatures on cases of the performance warranty contracting in European countries and states of the US. Major distresses influencing the performance of jointed concrete pavement were investigated and analyzed to be compared to the warranty duration, performance indicator, and threshold value of foreign countries.

Warranty contracting for pavements construction has been widely used in Europeans countries, Japan, and the U.S. and the benefits of warranty contract has been proven. This research investigated the European, U.S., and Japanese warranty contract policies and compared pros and cons. The most appropriate warranty contract policy solution is developed to fit in the Korean construction industry culture. Three main conclusions have been developed in this study: (1) performance specifications should be developed; (2) the systematic method is required to estimate the appropriate costs of performance bond and warranty period, etc.; and (3) short and long term plans for adopting performance warranty contract in Korea are suggested.

Despite continuous efforts by the construction industry to achieve better quality, it doesn't seem that much has been improved. This is mainly because current specifications do not satisfy a change in the market environment, which is that a higher level of quality is now demanded by users. Quality improvement efforts have been satisfied merely to meet specifications. On the other hand, advanced countries have been experienced great success in their construction techniques and have reduced costs by introducing apay adjustment system to the construction industry, in which compensation is based on performance. Following their example, Koreashould introduce such a pay adjustment system in order to motivate the members of our construction industry to achieve better quality and a higher level of construction techniques. However, there has been a lack of a rational approach to the development of a system for cost coordination, as well as performance and quality inspection. Thus, in this study a legal and logical plan was developed that can be used to adjust the construction cost, along with the performance inspection of quality results, in order to introduce a pay adjustment system that is appropriate for domestic regulations.

Performance-based Project Delivery System(PPDS) is one of Project Delivery System that when owner ask for performance than constructor feel free to choose materials, technology, an engineering method. PPDS rank higher position than Performance Warranty Contract and Technical Proposal Bid. This study aims to propose Improvement Idea for PPDS that based Housing Performance Grading Indication System. 'Request-performance Checklist' is used as communication means(between owner and constructor) and a kind of corroborative facts make the procedures achievement of project like contract easier.
