Survey on Life-Cycle Performance of Civil Structures and Infrastructure Systems

The Special Project approved by the SEI Technical Activities Division (TAD) Executive Committee for the development of this state-of-the-art report included a survey and an International Workshop on Life-Cycle Performance of Civil Structure and Infrastructure Systems, which was held by invitation only at the ASCE headquarters in Reston, Virginia, on November 10, 2015. The survey was disseminated to selected researchers and experts from universities, industries, engineering firms, and agencies active in the field of life-cycle civil engineering. A brief overview of the main results of the survey are presented in this appendix with emphasis on life-cycle concepts and methods, deterioration and damage evaluation, life-cycle performance indicators, inspection and maintenance procedures, life-cycle cost analysis, and implementation in design practice.
