Construction scheduling is a complex process that features multitudinous sequences of various tasks or activities necessary to accomplish the project within the stipulated duration. Furthermore, determining the parameters influencing construction scheduling, such as the type of construction activities, its duration, dependency relationship, associated probability of occurrence are arduous and uncertain. Hitherto, construction project scheduling predominantly depends on traditional methods, namely Program Evaluation and Review Technique (PERT), Critical Path Method (CPM), Precedence Diagramming Method (PDM) and so on. However, these prevailing scheduling techniques fall short in ascertaining the precarious parameters to establish accurate schedules. Consequently, a more competent approach is required to address the fuzziness and stochastic characteristics of construction schedules. This research proposes integrating Graphical Evaluation and Review Technique (GERT) and Fuzzy Logic (FL) to create Fuzzy-based GERT (F-GERT) for scheduling construction projects. F-GERT utilizes fuzzy operations to handle uncertainty in activity durations. Initial application to a two-storey residential building project demonstrates proximity to the as-built schedule. To reinforce the applicability of F-GERT, it is incorporated for scheduling forty-five real-time construction projects and accuracy is evaluated by comparing it with the actual project duration. The results show the significance of the proposed method in comparison with the existing methods.
