STANDARD METHODS FOR ESTIMATION OF INITIAL, MAINTENANCE AND REPAIRING COSTS FOR LIFE CYCLE COST ANALYSIS OF GEOGRID REINFORCED SOIL WALL

Abstract

It is important how to estimate initial, maintenance and repairing costs for valuable life cycle analysis. Authors propose the standard method for estimation of these basic costs to evaluate life cycle cost of geogrid reinforced soil wall. Technical guide of Ministry of Land, Infrastructure, Transport and Tourism and construction management book published from Construction Research Institute of Japan were referenced in developing of initial or maintenance cost estimation. Scenario for all-repairing due to earthquake disaster was considered in developing of repairing cost estimation. This paper explains the developed estimation methods and compares basic costs of geogrid reinforced soil wall with L-shape wall or no-reinforced embankment. Content of this paper is from achievement produced by Technical Committee: Stage 4 established in IGS Japan chapter (2007-2011).
