MEP BIM PROCESS ‘DISCONNECTS’
SUMMARISED Absence of product BIM data
• Designers data‐rich generic libraries (usually Revit)
• Contractors’
products libraries (usually CAD mep+);
geometrically exact – but lacking data.
Split process does not embed data in As Fixed Model
Autodesk owns Revit
& CADmep+ ;
BIM Platform switch from design to installation stage
• Will both be continued and enabled to ‘talk’
to each other?
DISCONNECTS ARISE MAINLY WITH DATA – NOT GEOMETRY
SO CAN DATA BE HANDLED ANOTHER WAY?
• Manufacturers’
uncertainty
• Level 2 BIM aims confounded?
• Will one replace the other?
