This paper describes a probabilistic evaluation method of design alternatives for structures under construction to assess their safety in view of economical aspects. In the evaluation, a construction period is divided into several terms corresponding to the construction stages and several possible failure modes are considered in every term. The magnitudes of loads are estimated statistically by the extremevalue distribution. Delay or additional expense due to a failure is intuitively estimated by engineers for every damage level in each construction stage. The estimates are based on many parameters evaluated synthetically, in which the total anticipated expense and the additional expense required to fix the failure are included. The proposed evaluation method has been applied to a habour-construction to verify its applicability and efficiency.
