BIM (Building Information Modeling) technology, one or more accurate virtual models of a building are constructed digitally. They support design through its phases, allowing better analysis and control than manual processes. When completed, these computer-generated models contain precise geometry and data needed to support the construction, fabrication, and procurement activities through which the building is realized.
BIM software creates an intelligent 3D model to inform and communicate project decisions. It has various components:
• 2D: 2-Dimensional view
• 3D: 3-Dimensional Model
• 4D: + Time Schedule
• 5D: + Budget (Cost)
• 6D: + Facilities management (Maintenance)
• 7D: + Sustainability (Life Cycle)
• 8D: + Occupational safety and health
BIM software advocates report that 2D through 8D BIM provides dramatic opportunities for cutting waste and errors, shortening schedules, and improving management of finished buildings. However, the technology also requires major changes in existing building processes that rigidly define how information is handed from one party to another.
BIM helps centralize the building process on a digital document that is revised throughout the design and construction phases, giving the building owner a thorough representation of their new property. BIM 8Dcan enable the opportunity to detect and design out health and safety risks from the outset, which includes health and safety professionals on the design review team throughout the process.
