The BIM Handbook presents the technology and processes behind BIM and how architects, engineers, contractors and sub-contractors, construction and facility owners (AECO) can take advantage of the new technology and work process. Unlike CAD, BIM is a major paradigm shift in the documentation, work processes and exchange of project information. It facilitates collaboration and further automation, in both design and construction. AEC professionals need a handbook to guide them through the various BIM technologies and related processes. The collaborative nature of BIM requires professionals to view BIM from various industry perspectives and understand how BIM supports multiple project participants. The BIM Handbook reviews BIM processes and tools from multiple perspectives: the owner, architects and engineers, contractors, subcontractors and fabricators. The BIM Handbook combines in-depth technical background, business process discussion of each of the major professional groups in AECO, and offers guidelines for assessment, adoption and use. It includes  real world case studies identifying both the benefits and successes of BIM as well as the pitfalls and challenges. The book also includes study questions for professionals, educators and students to engage in discussions about the many issues with respect to implementing and transitioning to BIM.
