4. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks 4 Goals Revisited To consider conversion of the industry from the use of isolated and largely 2-D applications with minimal data transfer between them (with little potential for design or fabrication automation), to knowledge-rich 3-D applications, with fully integrated data exchange based on product models.

Sacks 5 drawings Only people can read Support manual design process, manual checking, manual production structured parametric 3D model People and machines can read Rendering, spatial conflict and other checks, generation of production instructions, (surface cutting, welding, assembly, robotics) What are the Implications of Drawings vs. 3D Models?

7. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks 7 IT Strategies in Building Not consistent across specialties or building sectors Each building sector has a different context, with different opportunities: Level of design and engineering within the sector Potential for automation (in design and/or fabrication) Value added by the sector Capitalization within sector Existing level of IT already being used Human resources

Sacks 8 Transit station designers Architectural practitioners Specialist architects (by building type) School designers Hospital designers Residential designers Specialist contractors (by facility type) General contractors Factories Clean rooms Transit facilities Hospitals Sub- contractors Curtain walls Elevators Cast in place concrete HVAC Roofing systems Mechanical systems Ceiling systems Design consultants Suppliers and Fabricators Building Industry Sectors

9. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks 9 Initial Criteria Economics: Turnover / Value-added / Capitalization Market share and competition with related sectors? Design and Engineering Added-Value? Accessibility – human resources? Process change – potential for automation in –Design? –Fabrication? Existing IT systems? Strong national trade organization? Prefabrication off-site vs. production on-site

10. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks 10 Consideration for each sector Level of design and engineering within the sector Potential for fabrication automation Value added by the sector Capitalization within sector Existing level of IT already being used That affect its likely moves toward advanced IT Competition within sector or with related sectors Strong national trade organizations Potential for design automation Off-site production vs. on-site
