Researchobjective methods

• Document how model based design is currently done
  in the early architectural design project
  planning phases
• Ask why model based design is performed
• Case projects
• case studies
• participant observation
• exploratory survey ?
• action research ?
• pragmatic approach, praxis
• Measuring results criteria, units of analysis
• Interpreting results meaning, usability,
  applicability
• Evaluating results reliability (ltgt hype)

Researchobjective methods

• qualitative
• why ?
• reasons
• because
• its available
• its required
• I get benefits (Olles reasoning)
• consequences
• ...
• methodical basis
• case test, evaluation, BIM noBIM

quantitative how ? - easier to document

Preliminary interview findings

• Traditional BIM aspects
• Process integration collaboration life
  cycle aspect
• Technical tool oriented aspect
• Project Design content aspect
• project volume/visual shape/architecture
• Functional requirement aspect
• need for space/buildings/property
• New needs and criteria for BIM
• Socio-political aspect
• wider political frameworks for construction
• enabling building
• Administrtive enterprise aspect
• project management administration
• company/enterprise resource planning ERP
• Project premises fostering, enabling factors
• project classification
• a) customer driven / user driven / need based
  projects
• b) facility construction business driven
  projects
• Project constraints limiting factors

Early building project information management A
critical review of contemporary BIM

• Introduction (1 page)
• State of the art in BIM (4...5 pages)
• History and evolution
• Approaches on BIM
• Technical approach CAD, standards, tools, data
  exchange
• Project owner approach management, control,
  requirements, guidelines
• Design approach quality, design development,
  integration, collaboration
• Construction approach costs data management,
  process planning, 4D
• Life-cycle approach use maintenance, FM, data
  recycling
• Literature findings
• Critical approach to BIM (2...3 pages)
• few critical voices, costs over quality
• richness and variations vs. single modelling
  method
• included in BIM vs. excluded information
• new aspects based on project planning early
  design
• This research project (2...3 pages)
• Research domain objectives
• Methodology
• Research results and industrial impact (2...3
  pages)
