Fig.2 Effect of BIM on Project Lifecycle Phases

Construction projects pass through three major Project Lifecycle Phases (PLP)s: Design [D], Construction [C] and Operations [O]. These phases are also subdivided into sub-phases which are in turn further subdivided into activities, sub-activities and tasks. This conceptual model (Fig. 2) depicts the effects of BIM on project lifecycle phases over the three BIM Stages.
