Abstract : Visual communication through graphical scheduling methods is often the point of failure for the planning and monitoring of construction projects. The proposed chronographic model studies the graphical visual representation of the schedule in the spatial dimension. This model classifies the scheduling entities, especially the activities, the resources and the area of work, into three types of entities. These entity types symbolize the construction operations, establish the relationships between them, and determine the direction of flow of information. Using these entities, the planner can define the graphical approach in order to display the schedule information under diverse, compatible layouts and switch between these layouts. The primary goal is for all stakeholders to have a better understanding of the scheduling logic. This paper describes the meta-model that is used to structure these entities into classes, define their classification criteria with the visual representation of the scheduling approaches, and infer the relationships amongst them. The use of the Entity Relationship (ER) model to create the meta-model ensures uniqueness and stability. The result is the development and implementation of a meta-model that allows the planner to display the schedule information's under diverse approaches, add/edit entities, organize them into classes and infer their behavior towards each other in order to gain a better understanding of their roles. The validation process is done through the generation of the ER conceptual data model, adapted to the Chronographic construction scheduling approach that embraces change while maintaining consistency and self-validation despite the addition of new entities in classes.
