This podcast provides an introduction to 3D and 4D modeling, and identifies practical uses of this emerging project delivery method to streamline project schedules and reduce costs. It will provide insights into why the value of 4-D extends far beyond the planning stage of a project into construction, troubleshooting and even claim presentation through the use of custom animation to be able to investigate specific construction sequences, highlight design conflicts, and analyze an as-planned v. as-built schedule comparison in real time.
