Why use BIM ?
CAD and GIS• Boundaries• 2D or 3D• Fragmented• Obscure Meaning
DOCUMENT / IMAGE
• Not usable
• Not re-usable
BIM• “Mug”• Shapes and symbols• has Materials• has Capacity• kind of Equipment• touches “Table”
Efficiency and accuracy
© 1994 Thomas LiebichBIM means:
• ALL of the information, not just the shape
• A digital representation of physical AND functional characteristics of a facility
Other benefits
Can we get …… energy prediction… cost certainty… day lighting
© 1994 Thomas Liebich
Rationale for BIM
Sharing Structured Information …… not documents… not just 3D clashing … not just one application
Each input gives …… Many outputs … and new applications… Many checks … and automated checking… Many workflows … and more interoperability

‘House’ 1993Rachel WhitereadTurner Prize winner
“Fireplaces bulge outwards from the walls, doorknobs are rounded hollows. Architraves have become chiselled incisions running around the monument, forms as mysterious as the hieroglyphs on Egyptian tombs.”

• “For the first time I could understand a building design. It allowed me to contribute and comment (both positively and negatively) rather than just having to look at a flat drawing.”

• replacement of the “drawing board” and “typewriter”
• Use of smaller, more efficient tools
“lonely”,
“proprietary”
Little checking
possible
Managed separate discipline “BIM”s with attached data. Integration on the basis of special middleware. 4D Programme and 5D cost and other ‘layers’ of data. Existing contracts and relationships are unchanged.
Integration enabled by buildingSMART IFC / IFD / IDM. Managed by a collaborative model server, with concurrent engineering processes.
Model is the central deliverable.
Using the semantic web to create “big data” for smart CITIES and smart GRIDS
Joining facility behaviour to social outcomes,
• Models can be amalgamated within both Navisworks and Revit for the purposes of clash detection.
• Revit offers basic functional clash checking of building components.

Clash detection
• Often referred to as 4D BIM
• ‘Tasks’ assigned to various objects, and can be bi-directionally linked to external schedules in some of the widely used planning packages (Primavera / MS Project etc...) or as .csv files
• Allows time based clash detection, logistical optimisation and assessment of various options in terms of buildability.
• Studies carried out on most efficient forms of file for use and transfer as various options available.

Time related analysis
This can be extended in Navisworks or Synchro by linking with time analysis in order to detect for ‘clashes’ in the programming sequence (such as crane locations and columns).
