IMPROVING COMMUNICATION OF SCHEDULING INFORMATION OF EARTHWORK CONSTRUCTION PROCESS USING 4D VISUALISATION MODEL IN ROAD PROJECTS

Abstract: Innovative visualization technology applied to construction simulation and optimization has the potential to improve communications and coordination amongst the project stakeholders. In this context and in the drive for innovation in construction management, this paper introduces a framework of a 4D prototype for the automatic generation of visual terrain surfaces during earthwork construction processes. The framework has been designed and developed by integrating road design data, quantities of cut and fill, productivity models, algorithms for modelling terrain profiles and a road profile visualiser. The paper details the prototype of 4D visualization model (4DVM) that has been designed and developed in this research using innovative methodology where 4D models of terrain surfaces are generated based on coordinate data and the productivity of earthwork. The model has been demonstrated with a case study that was used to validate the model. The 4DVM is intended to assist project planners/construction managers in logical decision making processes for construction scheduling and resource planning. It will also improve the communication gap amongst the construction team and consequently improve site coordination and operations.

Keywords: Earthwork operations, innovative methodology, road profile generation, schedule communication, 4D visualization model (4DVM)
