• 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

• Improved site use planning and coordination with ongoing operations

• Marketing purposes and publicity

(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
