This chapter explores key aspects of integrated project design using the extreme collaboration methodology, which enables the construction of BIM models that integrate architecture, structures, and MEP, using a “war room” or “information room” (i-room) where various project specialists interact in real time. To achieve the highest degree of integration within a project, the BIM model is then sent to a robotic arm that through additive manufacturing techniques, prints concrete elements previously designed in the i-room—in short, total machine–machine integration (BIM-robot).
