[CAD Note] Additional BIM advantages - animated 4D+5D Scheduling.
When we combine the automated extraction of quantities over a timelined 4-D model we add a fifth dimension, commonly known as "5D". The power of 5-D scheduling allow us to exploit the relationships between the objects' timeline within the 4-D environment, and then report on their subsequent quantity or cost at particular points in time.
In simple terms, the consequence of task occurrences (or not), and their relationships to one another , allows us to investigate limitless permutations of quantum at any point in time. Some examples of this would be to extract cubic metres of concrete to be poured in the following week onto a dayworks schedule, or a $ value of work complete in a monthly cost plan forecast. Such methods are ideal for optioneering and assessing the client's risk and financial implications. The clear downstream benefits of 4-D and 5-D during the construction phase of a project menas that selection of design consultants with the requisite modelling skills is now more important than ever.
