The engineering industry has set up the foundation for Taiwanese economical and industrial development. During all phases of the developments, the engineering enterprises play the heavy role respectively in various engineering stages, such as feasibility study, environment impact evaluation, planning, design, construction, test, management, trainning, operation and maintenance etc. of engineering projects. Following the expansion in scale and versatility in content of the engineering project, the turn-key contract type instead of the traditional design and then construction splitted contract type will become more and more popular in engineering industry. Especially, the BOT and BOO of the turn-key contract in Taiwan public engineering projects are set with higher priority considering both the engineering benefit to the public and the finacial effectiveness of the government. Taiwan became the #144 member entity of WTO in early of year 2002 just soon after the #143 member of China in the late 2001. The mutual market oppening induces not only more competition but also more opportunity to the industries of the WTO member entities. The top management of individual enterprises shall consider thoroughly and work out an approach of theirwon leading to concord with the world trend, strengthen the competitive advantages, and survive forever in the industry. The research is started with the analysis of Taiwanese engineering industry. The resource-based view points and strategic management activities outline the core competence capabilities and advantages in various work stages of the indussstry. The key successful factors in the industry are recommended as : (1) financing capability; (2) business reputation and customer relationship; (3) capabilities of planning, design and cost estimate; (4) economical scale and negotiation capability; (5) engineering management and integration capabilities; and (6) operation and maintenance capability. The CTCI Corporation is also taken as an example introducing his operation methods and strategies which are worthwhile for reference. BOT or BOO stated in this research is on the prime contract with the real owner, usually the government. The prime contractor who is then called as the ¡§second owner¡¨ shall use every available resource in the industry to complete the project on schedule, in good quality, and earn the appropriate profit for his enterprise. Sub-contracting, therefore is still the same as what people did in the traditional engineering projects. Either big scale complex engineering enterprises or small size expert firms can still find theirown way for future operation. Talking about the tendering competition, the final game is almost staied on the financial issues. The learning curve, scale economic and expertization of the low cost strategy chain up the concentration and differenciation strategies. All of these will promote enterprises¡¦ capabilities through the improvement in technical aspects, project management, enterprise processing and resource integration, resource leverage etc.. The engineering enterprises, after evaluating their core competitive advantages, may choose and consolidate the market zone most suitable for them and extend therefrom the market through the alliance.
