Novel Integration of Sustainable and Construction Decisions into the Design Bid Build Project Delivery Method Using BPMN

A recent study on the cost of green buildings indicated that Resource Reuse is the category of credits least often achieved in LEED-certified projects. The literature suggests that there are a number of constraints and barriers to resource reuse, but perhaps the most critical one is the lack of easily accessible information about resource availability and usability. The emerging industries of building materials reuse and de-construction in the United States suffers from the absence of a “system” that would streamline business processes, establish a supply-demand chain, and connect vendors and deconstruction contractors with architects. This research derives an innovative restructuring of the architectural design process that enables resource reuse in new construction. We developed this model by capturing expert knowledge using a Delphi research protocol and mapped the Building Materials Reuse Workflow in Business Process Modeling and Notation language. We set out the knowledgebase requirements that should be integrated with Building Information Modeling to support decision-making by architects and project stakeholders.
