The BIM Handbook presents the technology and processes behind BIM to aid architects, engineers, contractors and sub-contractors, construction and facility owners (AECO). 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, and study questions for professionals, educators and students to engage in discussions about the many issues with respect to implementing and transitioning to BIM.
