The Architecture, Engineering and Construction (AEC) industry is facing a paradigm shift in the adoption of Building Information Modelling (BIM). However, the shift to its adoption and implementation in the emerging markets has brought distortion in both the business processes and environment for Small and Medium Enterprises (SME architectural) in the industry. This is attributed to the lack of clear orientation in Human Capital Development of the firms. This paper identifies the different strategies concerning the development of the IT managers human capital; development. This is achieved by identifying how BIM adopters differ from non-adopters in the ways their IT manager?s Human capital development is considered. The study involves two-step analysis; empirical enquiry to identify the various indicators of the IT manager?s human capital development and the analysis of its impact on BIM adoption. The empirical enquiry comprised of research framework and fieldwork data collection. The framework was used to collect data from the fieldwork. It involved a questionnaire survey with a sample of SME architectural firms in Nigeria. The survey involved administering questionnaires by hand to 351 firms within nine cities in Nigeria during September 2015. It yielded 228 completed questionnaires by the end of December 2015. Using regression analysis, the result indicates that, there are four critical indicators that determine the role of IT manager in BIM innovation, these are; the educational attainment, nature of employment, previous IT experience and job satisfaction.
