’4D Coordination Model’ for MEP Renovation via BIM

From AECbytes.com, an excellent website:

This article describes a different case, in which the BIM model was used in a unique approach to project phasing for a large-scale MEP renovation of a medical research facility, Old Jordan Hall, at the University of Virginia.

In this project, the model was employed as more than a strictly visual tool or geometry-based clash detection tool. By adding the component of time to the 3D model, at specific events during each phase and sub-phase of the basement mechanical room renovation, the model served as a true 4D coordination model, allowing the construction team to make informed anticipatory decisions.

The 4D coordination model produced automated data for the team to perform discrete event simulation (DES), which evaluates specific, sequenced instances in a larger ordering system. The DES data from the 4D coordination model gave the team advance warning of potential problems and thus the ability to troubleshoot ahead of time.
