Example, a mobile crane is assigned to a 'roof cladding' task. The crane will only be required on site for the first 50% of the task to load the panels then it can removed. Having the ability/option to make the crane disappear after a certain amount of time would go a long way in supporting the logistics planning in the 4D model.
