Gantt charts are used to communicate programme tasks, logic and planned construction sequence before and during construction. Common issues with this method are: 1. Inability for stakeholders to consume the plan quickly and to its full extent, regardless of skill and experience. 2. Inability to quickly identify opportunities for faster, more efficient sequencing and test ‘what if’ scenarios. 3. Fosters the likelihood of delays due to unforeseen planning and sequencing clashes. Innovating this traditional method using 4D modelling solves these issues simply by visualising the plan.
