• BIM model?• Bouw Informatie Model?• Modelling vs. Modeling?

• M = Model• M = Management

• BiM vs BIm• BEM (Environment)

Model versus Documenten

Page 12: BIM State-of-the-Art (IE-Net Studiedag 16 Oktober 2013)

• Grafische objecten (lijn, cirkel)• Direct• Layers, Symbolen, ...• Geen integratie 2D/3D• Geen synchronisatie• Informatie minimaal

• Bouwkundige objecten• Indirect• Layers, Symbolen, ...• Integratie 2D/3D• Synchronisatie documenten• Informatie completer

Waarom niet gewoon CAD?

2D & 3D CAD BIM

• Parametrisch Ontwerpen (Grasshopper, Generative Components, CATIA)

• Mechanische CAD (SolidWorks, Inventor)

BIM versus Parametrisch Ontwerpen?

Page 14: BIM State-of-the-Art (IE-Net Studiedag 16 Oktober 2013)

• Reguliere + Vrije Geometrie• Focus op 3D• Niet-domein specifiek• Uitwisseling statische

geometrie; soms IFC

• Nog geometrische beperkingen• 3D & 2D geïntegreerd• Architectuur/Bouw/Constructie• Evolutie naar software-

agnostische processen

• Ambrose (2012) over ontwerp studio proces– “Abstraction is at the heart of most design studios

in schools of architecture”– BIM presents a “way of thinking that seeks to

simulate the construction of a building”– “The way we make architecture is being

transformed through the very digital tools, methods and processes we use”

Ontwerpproces met BIM

• Berwald (2008) over tekenen t.o.v BIM– “BIM provides convenience” but also “presents

complexities”– “creating new objects [...] requires fewer skills” in

2D CAD, tegenover aanmaken van eigen componenten in BIM (families, objects)

– In 2D CAD “single set of methods can be applied to represent anything”

• Geen (weinig) vraag van opdrachtgevers• Geen vraag van overheid

• Cfr. scenario EPB/EPC?– EU Regelgeving– Nationale implementatie– Architecten besteden het uit

• BIM = wacht niet op de anderen!

Rol van de overheid?
