The potentials of a bottom-up knowledge diffusion approach towards achieving digitization of the built industry are limitless. Exposing Tertiary Institution Students to the capabilities and modalities of Building Information Modelling (BIM) before their entry into professional practice creates a gradual knowledge diffusion and process adoption. The Student Advocacy Program is a program designed to create BIM awareness amongst students of Tertiary Institutions in Africa. The modules of this program entails selecting Student Advocate Team in each university in various countries. The selected Student Advocates are trained virtually on BIM and how to present a BIM awareness program in their various institutions. The event staged in each institution are then ranked according to predefined metrics to select the highest ranking. The Advocates of top rank universities would have the opportunity to attend a fully-funded BIM (or construction related) conference outside their country of study.
