Isolated Collapsed But-For Delay Analysis Methodology
Publication: Journal of Construction Engineering and Management
Volume 135, Issue 7
Abstract
Schedule delays are common in construction projects. Although many methods have been developed for analyzing and measuring schedule delays for construction projects, each method has functional limitations and use prerequisites. No one method is acceptable for all project participants under all circumstances. This study presents the isolated collapsed but-for (ICBF) method, an innovative delay analysis method for construction projects. During analysis, the ICBF method requires as-planned and as-built schedules as well as identified liability documents with key delay events to perform its analysis approach. Based on its application to an illustrative case and comparisons with other methods, the ICBF method is effective for delay analysis. Results provided by the proposed method can be easily traced to the actual case in an as-built schedule.
