Traditional construction planning and performance control tools such as Gantt Charts and S Curves fail to visually represent physical project progress, construction sequence, interfaces and the critical path, which means that decision makers carry out their job with incomplete information. Moreover, these tools motivate a quantity-oriented mindset and a project island approach. Furthermore, traditional information flows in projects are inefficient since these present a significant lag between data collection and project status reporting. With improvements in technology and enhanced visualization through 3D object-based models linked to the schedule (time being the fourth dimension), opportunities arise that enable bridging the information and communication gaps currently experienced in planning and evaluating as built performance in a Building Information Modelling (BIM) approach. 4D BIM has been seldom implemented in the execution phase of projects and has been utilized merely as a preconstruction planning tool. The end goal of the research is to make recommendations on how to apply 4D BIM during the site execution phase to improve construction performance control in mega projects and provide a conceptual model of a work methodology to be implemented in civil engineering projects...
