Abstract— one of the most promising advances in the architectural, engineering, and construction (AEC) industry is buildinginformation modelling (BIM). BIM technology creates a digitally created exact virtual representation of a building. When finished, thecomputer-generated model will include precise geometry and important data to help the building's construction, manufacturing, andprocurement activities. BIM also accommodates many of the tasks required to model a building's lifecycle, laying the groundwork fornew construction capabilities as well as changes in project team responsibilities and relationships. When used correctly, BIM allowsfor a more integrated design and construction process, resulting in higher- quality buildings at cheaper costs and shorter projecttimelines. This chapter opens with a discussion of current construction processes, as well as the inefficiencies that these practicesentail. It then goes on to describe the technology underlying BIM as well as how to effectively take use of the new business processes itoffers throughout a building's whole lifecycle. It finishes with a discussion of the numerous issues that may arise while transitioningto BIM technology.Keywords— Building Information Modeling, Revit software, AEC Industry, BIM, Digital Modeling, Digital Construction, AugmentedReality
