10. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks Technology Derivation Paths Automated connection detailing was a recently developed innovation in steel design/detailing. What other technologies were needed to achieve this? Any particular technology is built upon other technologies. Some technologies, even those not yet available,are achievable, if we understand what other technologies are needed. Automated connection detailing 3-D building model Deriv. & transfer of loads Auto. Structural analysis

11. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks Technology Derivation Paths Suppose that we want to automate the derivation of bill of materials generation. What other technologies would be needed to achieve this? Part & material BOM 3-D building model Auto. Area & volume calc.

12. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks Automated rebar placement Technology Derivation Paths Is there a technology, or can we conceive of one, that would automatically place rebar correctly in different contexts: precast, tilt-up or in-place concrete? What other technologies would be needed to achieve this? Automated rebar bending Rebar placement robot Robot spot welder 3-D building model

13. Strategies for IT Adoption in the Building Industry © 2002 Prof. C.M. Eastman & Dr. R. Sacks But rebar placement itself requires certain technology. Automated rebar placement Automated rebar bending Rebar placement robot Robot spot welder 3-D building model Accurate setup and placement Vision and feedback OR Technology Derivation Paths
