The analysis of delay claims has become an extremely complex, time-consuming and costly process. This is because the analysis entails extensive exploring of factual data and a thorough study of the effects of actual events on the progress of works. Existing delay analysis techniques have many pros and cons and are not in line with current planning software packages. one of the existing delay analysis methods is the windows method, which is a common method that has gained some superiority over other methods due to its credibility and acceptability by claim analysts, arbitrators and courts. However, what is uncommon is the methodology of analyzing the windows and demonstrating of the results.
Moreover, windows analysis has some drawbacks which can be improved mainly by reducing the window size and automating of the process. The aim of this paper is to propose a new automated method for analyzing delay claims using daily windows, spreadsheets sheets and database. The analysis includes both extensions of time and delay damages calculation based on as-planned and updated schedules available. The proposed method will greatly reduce the analysis time as compared to the conventional windows method. A real life project is introduced as a case study to illustrate the computation mechanism. The proposed method can be further improved in order to be integrated with commercial planning software for more development of the delay analysis processes.
