The increasing diversity and continuous evolution of BIM technologies, tools, and related skills, further complicated by disciplinary biases toward their implementation, are grand challenges for developing an all-inclusive understanding of BIM. In facing these challenges, educators and trainees need to develop BIM-focused learning paths to understand the variation of technological features that drive the functionality of BIM tools and their similarities and differences. This chapter summarizes fundamental BIM technological features to explain how BIM tools support or limit these features in diverse ways, leading to varied BIM implementation perspectives, experience, and outcomes for different users. While it enables educators and learners to investigate technological features in individual BIM tools, this chapter also presents the notion of distributed BIM in custom toolkits, whereby practitioners assemble a variety of BIM tools with complementary technology features to support coherent and coordinated BIM implementation in projects. With this overview of diverse BIM technologies, varied BIM tools, and dynamic ecologies of digital practice in projects, this chapter will discuss four skill development tracks for BIM educators and learners to clarify how they must address a variety of technology management, development, and application skills in their complementary BIM training programs.
