QuickTime™ jaTIFF (ei pakattu) pakkauksen purkuohjelma

tarvitaan elokuvan katselemiseen.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)

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

1. Introduction (1 page)2. State of the art in BIM (4...5 pages)

1. History and evolution2. Approaches on BIM

1. Technical approach CAD, standards, tools, data exchange2. Project owner approach management, control, requirements, guidelines3. Design approach quality, design development, integration,

collaboration4. Construction approach costs & data management, process planning, 4D5. Life-cycle approach use & maintenance, FM, ”data recycling”

3. Literature findings3. 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 informationnew aspects based on project planning & early

design

4. This research project (2...3 pages)1. Research domain & objectives2. Methodology

5. Research results and industrial impact (2...3 pages)• Quantification of results criteria, validation, units of measurement & analysis• Implementation & exploitation

6. Conclusions (1/2 page) early design information management eDIMnear future challenges
