Abstract: This article helps us to fully understand the value network of BIM/VDC through measuring BIM's disruption. First of all, the author makes a comparison between two kinds of innovation with Clayton Christensen's ideas of "sustaining innovation" and "disruptive innovation." Secondly, he points out that disruptive innovations occur in two ways: "low-end' disruption and "new-market" disruption. And then, the value network theory explains why the author regards BIM as a disruptive innovation: BIM has introduced new capabilities, spawned new markets, attracted new customers, and will finally establish its new value network. In the end, the author points out that to successfully navigate BIM/VDC's future value network for the AEC industry, we should be open-minded, embrace the strange and ready to explore the opportunity for disruptive innovations.
