10. 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 (<> hype)

11. Researchobjective & methods qualitative why ? • reasons • because • it’s available • it’s required • I get benefits (Olles reasoning) • consequences • ... • methodical basis • case test, evaluation, BIM | noBIM quantitative how ? - easier to document

13. 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 • known & documented constraints
