To solve existing old building was reconstruction whose regulation has been stronger than before. On the other side, Remodeling project become active. In spite of Remodeling project activation policy of a government, relaxation of some regulation and Remodeling technology development, etc, but Domestic Remodeling market place did nor yet vitalize. This is application of existing resources on condition which has working place, restriction of method and unreliable existing building’s career management, so difficulty of getting information has many risk factors. The more serious problem is lack of understanding about Remodeling, limit of communication and lack of systematic process about complexity of project, etc. of Remodeling project operator and each participant, happening construction term delay, waste of budget, a fall of quality. This study suggests each process work scope of project execution and various kinds analysis tools for decision making for efficient management and building of project system and builds project execution process system. identification.

The purpose of this study is to investigate the variation of tension of existing tendon by additional tendon installation. As a result of the analysis, it was found that the tension value was decreased overall compared with before tenden reinforcement. The cause of the reduction of tension is presumably due to the effect of reinforcement.
