IT Dependent Innovations in Construction

1. IT Dependent Innovations in Construction

2. IT Innovations New or enhanced software systems For example: • Advanced modeling software • Automated detailing • Automated bills of material, procurement, inventory management

3. IT Dependent Innovations New or enhanced process activities that are dependent on information technology. For these, IT is an enabler. For example: • Monitoring of project performance. • Robotic and other automated production and construction methods. • Tracking precast pieces with RFID tags.

4. Monitoring using crane black-box

5. Monitoring using crane black-box

6. Crane monitoring data Detailed construction schedule Deduce activity performance Identity, location, geometry of building elements Project monitoring using equipment data Report exceptional material consumption or exceptional activity duration

7. Automated project performance control (APPC) Construction schedule Monitor laborers Automatic construction project monitoring Monitor crane 3-D building model

8. Integrated procurement and materials management 3D CAD Subsomboon et al. 2002 – ASCE FIAPP Specialty conference

9. Computerized Schedule 3D Building Model 4D CAD • Simulate construction progress • Detect spatial conflicts in construction • Update project schedule VR Simulation

10. 3-D building model Auto. Structural analysis Deriv. & transfer of loads Technology Derivation Paths Automated connection detailing was a recently developed innovation in steel design/detailing. What other technologies were needed to achieve this? Automated connection detailing 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.

11. 3-D building model Auto. Area & volume calc. 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

12. Robot spot welder Rebar placement robot Automated rebar bending 3-D building model 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 placement

13. Accurate setup and placement Robot spot welder Rebar placement robot Automated rebar placement Vision and feedback Automated rebar bending 3-D building model Technology Derivation Paths But rebar placement itself requires certain technology. OR

14. 3-D building model Real-time recognition of part and placement Technology Derivation Paths An important quality control and facility management capability is to verify placement of parts/equipment in a building as it goes up. Verification of erection placement

15. 3-D building model Verification of erection placement Real-time recognition of part and placement Laser location definition Shape recognition from laser scan Technology Derivation Paths Real-time verification of part placement requires technology

16. 3-D building model Part identification by RFI or barcode Verification of erection placement Real-time recognition of part and placement Laser location definition Shape recognition from laser scan Technology Derivation Paths Real-time part identification requires technology

17. Technology Derivation Paths Robot spot welder Rebar placement robot Automated rebar placement Rebar automation equip. Automated rebar bending Real-time recognition of part and placement Automated connection detailing 3-D building model Deriv. & transfer of loads Auto. Area & volume calc.
