Abstract

As the complexity in construction projects increased, simply managing the obtained float values and critical path(s) by the CPM method usually results in more difficult schedule control and, consequently, in incorrect decision making due to non-realistic float values. This study thoroughly reviewed various float types in the literature and professional project management systems, and discussed five managerial essentials and three proactive strategies on mitigating challenging float-related problems based on the perspective of managing schedules by controlling floats. With some comments and suggestions, the outcomes of this study not only improve the knowledge level on schedule management but also provide a better understanding of float management to improve the quality of schedule management.

Keywords: Critical path method, Float management, Float, Project management, Review research, Schedule management.
