Evaluating a schedule means making a judgment about the schedule after thinking carefully about its duration, cost, and the probable quality of its deliverable product. Despite recent advances in 4D visualization, (i.e., 3D building geometry + time), only few have challenged its use in evaluating construction schedules. The intents of the planning that provide the means for evaluating schedules and making business-oriented decisions are missing during the visualization. Yet, 4D visualization has focused mainly on the visual detection of conflicts in time and space. This project proposes an approach to extend 4D visualization into a level we call perception, with the aim to support the decision-making process of a construction company during the phase of planning and execution. By gathering and then reproducing planning intents during the visualization of a large-scale building construction schedule, the application of our approach eases and accelerates the ability to comprehend a construction schedule. It also communicates planning intents among the project practitioners. A modeling tool and a simulation tool are utilized in order to acquire valid planning details. In this paper, our perception model that builds on a 4D model is presented. Then, the types and the sources of the planning intents, as well as a prototype implementation and an example, are described.
