The results of the study strongly recommend that proper and sufficient trainings directly related to the practical applications of the BOT project are essential to minimize or avoid unnecessary delay, especially for the quality control operation in the field. In addition, enhancement of the language skills in English is also critical for the engineers not only to better understand all the contract documents and related specifications, but also to improve the effectiveness of coordination and communication during the carry out of the project in which the cantilever bridge using full-span launch method constitutes the dominant part of the civil engineering works. The above mentioned are also necessary for the engineers and construction companies in Taiwan to uplift their competitiveness in the global markets
