Building Information Modelling (BIM) adoption is generally assessed through one of these two main approaches: Statistical evaluation of survey from stakeholders operating within a country or market and the use of macro BIM-adoption models and metrics. The paper “macro-BIM adoption: Comparative market analysis” sets a pace to continues development of comparative market studies. However, precedent is important for continues learning and adoption to contextualise this evolving field. This study aimed to set a unique precedent through comparative analysis of BIM adoption trends in the USA, UK and Australia to set a pace for beginners or early BIM adopting countries to learn from. This study is literature based analysed using content analysis. The study reveals the following:

• For a vibrant and even BIM adoption, government is involved;
• Government mandate facilitates wide BIM adoption and integrates a country’s industry to the world;
• The mandate also facilitates BIM research and training that lead to rise in country’s income through providing trainings and work force export;
• Diffusion dynamic varies at different times, depending on country’s flexibility to adoption of innovation;
• The dynamic also changes as the industry’s culture/regulation changes.

Recommendations are made based on the study findings especially to the new adopter countries planning to develop a strategy for macro-BIM adoption.
