  1. The Precast Concrete Industry A proposal for the adoption of advanced Information Technologies

  2. Introduction • Existing processes and business environment. • Available and suitable information technologies. • A framework target plan, including assessment of potential benefits. • Assess the expected costs of achieving the plan. • Analysis of the readiness for implementation of the framework plan. • A detailed plan for the next incremental step.

  3. Part 1: Environment - Scope What is Precast Concrete Construction ? • Construction of buildings and other facilities using precast concrete elements; • Precast concrete elements are reinforced concrete elements produced in a dedicated plant. They are transported and erected after curing. • For examples - Precast Concrete Institute

  4. Part 1: Environment - Scope What sub-sectors are there ? • Architectural Precast generally includes the production and erection of precast panels for facades of buildings. • Structural Precast generally includes production and erection of structural systems (assemblies of precast elements), and in certain instances of complete buildings.

  5. Part 1: Environment - Scope An economic review • approximately 380 plants in Canada, the US and Mexico, operated by some 160 producer companies.

  6. Part 1: Environment - Scope

  7. Part 1: Environment - Scope

  8. Part 1: Environment - Scope Who is involved ? • Owners/Clients • Architects • Structural Engineers • Precast Concrete Producers and Erectors • General Contractors • Material Suppliers • Designers and providers of other building systems

  9. Part 1: Environment - Process What activities are there ? • Win contract and acquire project • Assembly design • Detailed design • Planning and Scheduling • Production • Handling - Storage and Shipping • Erection

  10. Part 1: Environment - Process What are the information dependencies ? • Building design (geometry & systems) • Product design • Materials Procurement • Plan, Schedule and Production • Erection • Company Management information

  11. Part 1: EnvironmentA High Level Process Model

  12. Part 2: Information Technologies What is in use ? • CAD – 2-D drafting e.g. Precast Drawings • Structural Design applications e.g. LEAP • ERP software (production planning, materials management, human resources, accounting, etc.) • Scheduling software

  13. 41% of producers reported encountering problems in production due to ambiguities in design “often” or “very often”. Part 2: Computerization for Design (PCI/CPCI Survey 2001) (Arditi et al. 2000, ASCE Journal of Architectural Engineering)

  14. Part 2: Information Technologies What is the effectiveness of IT use ? • Errors are commonplace. • No integration – data is re-entered for each application. • Examples…

  16. Parking Deck 1

  17. Parking Deck 2

  18. Parking Deck 2

  19. Prison Complex

  20. Arena

  21. Part 2: Information Technologies What else is available ? • CAD: 3-D Modeling • Rendering, Animation and Virtual Reality, • CAM and Robotics, • B2B, collaboration portals, • Product Model based integration, • Automated data collection and monitoring

  22. Part 3: A Framework Target Plan • What are the long-term IT goals ? • What are the short-term IT goals ? • Potential local benefits – activities and cost-centers • Potential system benefits in the supply chain • A future process model

  23. Part 3:Long-term IT goalIntegration Formwork fabricator Architect or contractor Material suppliers Outside Exchanges Design Stage “B2B” exchanges Design application Integrated Precast/ Prestressed Data model Analysis application Enterprise Applications Shop drawing Application Internal Exchanges Materials order/ tracking app. Scheduling and workflow app. Production Stage Process planning application Mold design application Logistics and production app. Rebar bending application Robotics applications (Eastman & Augenbroe, 2000, presentation to PCI)

  24. Part 3:Short-term IT goal3-D Modeling Design Stage 3D Modeling of Precast Buildings Design application Analysis application Enterprise Applications Shop drawing Application Internal Exchanges Materials order/ tracking app. Scheduling and workflow app. Production Stage Process planning application Mold design application Logistics and production app. Rebar bending application Robotics applications (Eastman & Augenbroe, 2000, presentation to PCI)

  25. Part 3: Local benefits • Reduced drafting hours/salaries • Reduced drafting and production errors • Shortened sales response time • Shortened time to erection • Improved management information flows All of the above = Increased Market Share.

  26. Part 3: Supply chain benefits • Improved coordination with and support for project architects and engineers. • Shorter activity times for GC. • Lower overall cost for Owner. • Shorter overall duration – benefits all.

  27. Part 3: A future process model Precast Process Model

  28. Part 4: Expected Costs • What are the ‘hard’ costs ? • Initial investment in hardware and software • Annual maintenance fees • Training fees and salaries • Equipment

  29. Part 4: Expected Costs What are the ‘soft’ costs ? • Business re-organization and adaptation • Decreased productivity during ‘learning-curve’ period. • Management time (salaries) • Opportunity cost

  30. Part 5: Industry Readiness • What are the conditions that must exist ? • Which conditions are presently satisfied ? • Which conditions can be satisfied in the short-term? • Which conditions can be satisfied in the long-term?

  31. Preconditions Conditions Necessary Developments Part 5: What conditions must exist ? • Significant value-added portion • Perceived economic benefits • Available production automation technology • Computerization in the business environment • IT integration in external environment • Modeling software • Product model integration

  32. Part 5: Industry Readiness • Which conditions are currently satisfied ? • Significant value-added portion • Perceived economic benefits • Available production automation technology • Computerization in the business environment • IT integration in external environment • Modeling software • Product model integration  Materials are 15-20% of product cost  Yes; especially schedule, error reduction and market share  Yes; rebar, mold, casting and finish automation is available  Yes; enterprise management systems are common

  33. Part 5: Industry Readiness • Which conditions can be satisfied in the short-term? • Significant value-added portion • Perceived economic benefits • Available production automation technology • Computerization in the business environment • IT integration in external environment • Modeling software • Product model integration  Yes; development is now under way by Tekla. For example…  Yes; development is now under way by Georgia Tech

  34. Part 5: Industry Readiness • Which conditions can be satisfied in the long-term? • Significant value-added portion • Perceived economic benefits • Available production automation technology • Computerization in the business environment • IT integration in external environment • Modeling software • Product model integration  Through the IAI ?

  35. Part 6: The Next Step • What technologies and resources are required ? • 3-D Modeling Software and Product Model • software and model development teams • industry technical working teams • financing • What short term benefits are expected ? • reduced errors, • reduced lead times, • reduced engineering costs.

  36. Summary • Existing processes and business environment. • Available and suitable information technologies. • A framework target plan, including assessment of potential benefits. • Assess the expected costs of achieving the plan. • Analysis of the readiness for implementation of the framework plan. • A detailed plan for the next incremental step.
