Using 4D in a new ""2D + time"" Conceptualization""

Abstract: This paper describes a system that combines a 2D digital board that shows dynamically in rows and columns arranged in a special layout, starting and finishing dates of subcontractors work linked to the fourth dimension, time, coming from construction schedules. The system is the result of a research project whose objective is to improve planning, scheduling, and controlling the work of subcontractors of finishings in building projects. The system will be tested on case studies projects for planning, scheduling and controlling the work of subcontractors. It is expected that the systems will act as a powerful real time Visualization, Planning, Analysis and Communication Tool in the case studies. Despite the 3D case studies models were very useful for constructability and other purposes, the traditional 4D approach that combines 3D + time was not very useful when dealing with construction works that remained mainly ""hidden"" within the project 3D model. Applied to the case studies, the digital board shall provide different ways to display, communicate and understand information about resources, costs, dates and relationships coming from a traditional CPM network using 4D in a new 2D + time conceptualization.""
