A chronographic method for construction project planning

Abstract

Generally, the utilization of traditional scheduling methods represents a complex and cumbersome task for most project managers. Using the existing tools often requires long preparation, and the quality of the graphical output of the planning job is suboptimal. The lack of accuracy in the representation of the execution process diminishes the reliability of the schedule. This article proposes a new planning approach that that can simulate the real conditions of projects. The concepts of graphical scheduling models are analyzed to position the new chronographic approach among other graphical scheduling techniques. The theoretical concept, the mathematical model, and the graphical approach for this new planning method are summarized. Among other features, the proposed chronographic method allows the internal division of activities and relationships as a function of quantities, and new realistic types of floats are proposed. The output may be represented on numerous levels of hierarchical detail or as a combination of these levels. The result is modeling that produces improved visual clarity, increased flexibility, and more adaptability to changes for construction projects.Key words: planning, scheduling, modeling, time-scaled, chronographic method, Gantt, critical path method, precedence.
