4D is 33% cooler than 3D!

4D simulations are cool. That being said, current BIM solutions are pretty terrible at integrating the keyframing attributes to a model(trying to build it in after the fact in Navis??), that it begs the question of alternative workflows. In the current scenario of clientside apps, however, it does not seem possible to transparently define scheduling data behind the design model due to the limitations of interface and centralization of markets that focuses on A/E, not the builders.

Imagine if there was an interface into the model for contractors, that allowed access to specs, materials, cost, scheduling, and equipment phasing?
