The analysis results show that, in the early period of post coastal engineering under the tidal land development policies, up till 1981 when the development of concrete became the primary material used in coastal protection engineering projects. After year 2000, due to the influencing of the ecology concept, the goal of coastal engineering construction changed gradually towards Soft Engineering Protection and Environmental Construction in using low dike, and natural materials as the mainstream technique. The performance of life cycle shows that none of the 45 case projects have reached their end of life. The related factors affecting the life cycle reveals that natural disaster and geological is the most important factor for each project, as shown by the level of maintenance. Relative expenditure analysis reveals that within coastal engineering undertakings, repair and maintenance expenses exceed new construction projects in future years.
