Manufacturer details
• http://seek.autodesk.com/
Refer :
• http://bimobject.com/en
• http://www.nationalbimlibrary.com/manufacturers
Missing information :
Structural drawings & Reinforcement details
MEP details & coordination drawings
Inconsistent found in model:• Architectural wall & column
intersection not modeled properly• Clearance between
suspended ceiling and front door
• Room spaces are not assigned properly
Clash Detection:

• refers to components that are closer than a certain distance (a minimum clearance) from one another
Soft Clash: Hard clash : two objects
occupying the same spaceNo clearance

Refer :
• allows project stakeholders to view the planned construction of a facility over time on the screen

• Improved site use planning and coordination with ongoing operations
• Marketing purposes and publicity
Benefits:
Construction Schedule
Linking into 4d software and create selection set

(HC BIM QS) • construct a model from CAD drawings, specifications and other information available
• digitally measure geometric information to produce accurate quantities
• link the quantity information with project specific Bills of Quantities and Cost Plans
• create client specific reports

BIM collaboration in Multi Disciplinary Perspective
MV-BIM
• Upto 15% of the cost of a project is lost because of rework and avoidable collisions between trades
• Work parallel instead of linear
• Bring visibility and control to shared Information Models
• Immediately review the design progression during development and track critical decision making
Cobie: Revit model
• Type parameters & instance parameters
1.Adding Cobie information using Revit add on CTC2.Detailed Project information for Cobie
• Classification types
Element comparison
• Adding all required cobie information to the model
• Export model into industry foundation class
• Checking all cobie data information in federated model
• Export cobie data into excel spread sheet

Current Limitations and disadvantages
• Model analysis incomplete (Structural & Light analysis etc.)
• Missing information ex: STRUCTURAL, MEP which affect the analysis workflow.
• Lack of standards.
• Current Model is incomplete in Relation to “BIM”.
• Conflicts within used software's.
Recommendations for Future Improvements• Well designed BIM model in design stage.
• Multidisciplinary teams could then collaborate successfully with their project teams.
• Proper guidance & trainings before starting project.
• Information & knowledge sharing
