Windows-based delay analysis methods are the most accurate among various analysis methods for identifying and measuring construction schedule delays. These methods are homologous, but are suitable for different delay situations. This study compares four windows-based delay analysis methods to identify their advantages and limitations. The differences in terms of the perspectives of use prerequisite, functional capability, analytical process and accuracy of analysis results are discussed in terms of a simulated case. Study results are helpful for delay analysts in selecting a suitable method among different windows-based delay analysis methods.
