Abstract: Disclosed herein is software technology that facilitates collaboration on a BIM file. In one aspect, disclosed herein is a method that involves (1) providing presence information to a first client station associated with a first individual that is viewing a first rendered 3D model of a construction project, wherein the presence information comprises (a) information identifying at least a second individual that is viewing a second rendered 3D model of the construction project via a second client station, and (b) an indication of a position and orientation at which the second rendered 3D model is being rendered, (2) receiving, from the second client station, an indication of a change in either the position or orientation at which the second rendered 3D model is being rendered, (3) updating the presence information based on the received indication, and (4) providing the updated presence information to at least the first client station.
