Schedule delay is one of the worrying problems in the construction industry. Activity delays might increase project duration, cost and sometimes cause delay claim disputes between parties in construction projects. Some methods have been developed for analyzing and measuring project schedule delays, but most of those methods contain assumptions and subjective assessments. In order to identify the useful methods for projects in Indonesia, this study implements popular schedule delay analysis methods into a real project case in Indonesia which has varied relationships among activities and high frequency of concurrent delays. In this study, collecting and analyzing actual project schedule information, identifying delay events, executing delay analysis and comparing analytical results, have been completed to examine the possibilities of using available methods to provide reasonable or even correct outcomes. This study concludes that some of the available methods are unable to deal with concurrent delay problems and some result in different outcomes to the others. Therefore, choosing suitable methods would be an issue when solving delay analysis problems in Indonesia's construction projects.
