Interactive 4D-CAD

Abstract

While 4D models (3D plus time) are becoming more prevalent in design and construction, the characteristics and use of these tools is still being explored. Research at CIFE (Center for Integrated Facility Engineering) is focusing on the usability of the models - not only in terms of their visual and communicative impact - but impact on the construction design process. We are developing a 4D-CAD tool which enables construction designers to easily build and interact with a 4D model. The goal is to improve the decision power of 4D models by facilitating rapid prototyping and analysis of alternative schedule proposals.
