Early architectural design and BIMHannu Penttilä BIM.... what BIM ??
Early architectural design and BIMHannu Penttilä "all the conceivable data relevant to any building problem" (Harper 1968) BIM.... what BIM ??
Early architectural design and BIMHannu Penttilä standard & tool development curiosity & research interest commitment & will – national & company wide IT-strategies short history of building information modelling | BIM 199020002010 US NIST Dutch TNO Finnish VTT (Ratas) IGES initial graphics exchange specification STEP ISO 10303 standard for the exchange of product model data PDES process development execution systems ERPs PLMs PLIB parts library IFC industry foundation classes BuildingSmart pragmatic interest implementation for practice – project implementation – education & skills

Early architectural design and BIMHannu Penttilä Thesis phases & documentation Research interviews done (100%)  Early building project information mnagement: A critical review of contemporary BIM Project cases to be started  BIM case projects of early building phases (to be submitted 5/2009)  Testing and validating early building project information (12/2009) Parviainen architects large industrial case LPV-architects small public building, kindergarten Senaatti properties (1..2) valuable public buildings City of Helsinki HKR-rakennuttajat Lapinlahti hospital renovation accepted, paper to be submitted 7.11.2008 to 5th Nordic in Iceland 2009
Early architectural design and BIMHannu Penttilä Research objective & 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)
Early architectural design and BIMHannu Penttilä Research objective & 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
Early architectural design and BIMHannu Penttilä 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
