Building Information Modeling (BIM) is a process for creating and managing information on a construction project across the project lifecycle. It involves creating a virtual 3D model of a building that contains both geometric and nongraphic data. Key benefits of BIM include improved design coordination, reduced construction conflicts and waste, more accurate cost estimation, and better project outcomes. BIM involves integrating parametric object-oriented building components within a 3D model and sharing this information collaboratively between stakeholders in a digital format. It allows for clash detection and simulations to optimize construction planning and operations.
8. What is BIM ?
• Building Information Modeling is about
creating and using a 3D, intelligent model for
planning, designing, building and managing
infrastructure.
Continuity
Agility
Clarity
9. What is BIM ?
• Multiple models into composite model
10. What is BIM ?
• 3D Model
• Information rich
• Intelligent objects
• Parametric data
• Data sharing-Cloud
• Clash detection
• Pre Fabrication
• Integrated Process
• Collaborative
working
11. Why we need BIM?
• 2D Environment / 3D world
• Traditional problems
• Sustainable design and energy performance
compliance
• Waste within construction
• New technology
• Best practice
12. History & Evolution of BIM
• Introduced by Autodesk in 2002, the term
building information modeling (BIM)
18. A BIM centric Approach Delivers :
• Automation of design and construction
documentation and deliverables
• Multiple design iterations informed by detailed
analysis and simulation
• Sustainable design and energy regulation
compliance
• Realistic, compelling visualizations including
images and animations
• Construction site simulation and management
• Accurate quantity take off and planning

21. •20% reduction in build costs (buy 4, get one free!)
•33% reduction is costs over the lifetime of the building
•47% to 65% reduction in conflicts and re-work during construction
•44% to 59% increase in the overall project quality
•35% to 43% reduction in risk, better predictability of outcomes
•34% to 40% better performing completed infrastructure
•
•32% to 38% improvement in review and approval cycles
How BIM affects project:
27. Move unit so that coresponding duct work does not go
through the ceiling of the 2nd floor corridor or Director’s
office

29. Conclusion
• Industry needs to establish a clear best
practice with BIM
• Real risk that not having BIM experience could
exclude you from future projects
• The introduction of BIM is not about the
adoption of any software; it is probably the
most significant operational change process
you will ever make
