What is a 4D BIM model and what it can be used for?

The construction of the 4D models enables the various participants (from architects, designers, contractors to clients) of a construction project, to visualize the entire duration of a series of events and display the progress of construction activities through the lifetime of the project.

This BIM-centric approach towards project management technique has a very high potential to improve the project management and delivery of construction project, of any size or complexity.
