  1. Integrating Technology with Lean Construction NWCCC November 17, 2010

  2. Agenda • Lewis Lean • Case Study: Modeled Work Packages • Case Study: Bluebeam • Case Study: SharePoint • Q & A

  3. Minimize Waste Optimize Delivery

  4. Minimize Waste Minimize Waste Reduce worker idle time Prevent accidents Avoid over/under design Optimize just in time delivery Eliminate unnecessary steps Prevent defects Shorten learning curve

  5. Optimize Delivery Optimize Delivery Align goals Foster trust Establish accountability Ensure peak performance

  6. Checklist

  7. Case Study Modeled Work Packages

  8. Modeled Work Packages

  9. The Project: • UW Housing Concrete • Self-performed concrete work • Design-bid-build delivery • Lump sum, down-market bid • The Challenge: • Accomplish tight schedule • Prevent injuries and accidents • Eliminate impacts and rework • Beat aggressive labor budget

  10. The Approach: Put the Model in Our Crews’ Hands

  11. The Approach: Combine the Model with Work Packages

  12. Identifying Document Conflicts Virtually, Not in the Field

  13. Using the Model’s Visualization to Plan the Work

  14. Plan Forming and Pours

  15. Identify Repetition for Prefab

  16. 4D to Fine-Tune Schedule

  17. Quantities to Prorate Budgets G2 – West: Conc: 55 CY Form: 3,122 SF G2 – East: Conc: 52 CY Form: 3,062 SF G1 – West: Conc: 72 CY Form: 4,076 SF G1 – East: Conc: 75 CY Form: 4,356 SF

  18. Breaking Down the Model into the Work Segments

  19. Using Modeled Assembly Drawings to Execute the Work

  20. Many Types of Activities to Build

  21. Shear Walls: One Type of Activity

  22. Shear Walls: Broken into Segments G1 - West

  23. Shear Walls: Broken into Segments G1 - East

  24. Shear Walls: Broken into Segments G2 - West

  25. Shear Walls: Broken into Segments G2 - East

  26. Shear Walls: Broken into Segments G2 - West G2 - East G1 - West G1 - East

  27. Assembly Drawing for Each Segment

  28. Planning Work Packages to Remove Obstacles

  29. Coupling Modeled Assembly Dwgs with Work Packages

  30. Sharing the Budget with Our Crews for Goal Setting

  31. Breaking the Budget into Segments Shear walls total: Conc: 255 CY = 89 Hrs Form: 14,616 SF = 1,169 Hrs

  32. G2 – West G2 – East G1 – West G1 – East Shearwalls

  33. G2 – West: Conc: 55 CY Form: 3,122 SF G2 – East: Conc: 52 CY Form: 3,062 SF G1 – West: Conc: 72 CY Form: 4,076 SF G1 – East: Conc: 75 CY Form: 4,356 SF Shearwalls

  34. G2 – West: Conc: 55 CY Form: 3,122 SF G2 – East: Conc: 52 CY Form: 3,062 SF G1 – West: Conc: 72 CY Form: 4,076 SF G1 – East: Conc: 75 CY Form: 4,356 SF Conc. Placing = 0.35 MH/CY Wall Forming = 0.08 MH/SF Shearwalls

  35. G2 – West: Conc: 55 CY = 19 Hrs Form: 3,122 SF = 250 Hrs G2 – East: Conc: 52 CY = 18 Hrs Form: 3,062 SF = 245 Hrs G1 – West: Conc: 72 CY = 25 Hrs Form: 4,076 SF = 326 Hrs G1 – East: Conc: 75 CY = 26 Hrs Form: 4,356 SF = 349 Hrs Conc. Placing = 0.35 MH/CY Wall Forming = 0.08 MH/SF Shearwalls

  36. G2 – West: Conc: 55 CY Form: 3,122 SF

  37. G2 – West: Conc: 55 CY Form: 3,122 SF

  38. G2 – West: Conc: 55 CY Form: 3,122 SF

  39. G2 – West: Conc: 55 CY Form: 3,122 SF

  40. Providing Feedback to Optimize Performance

  41. G2 – West: Conc: 55 CY Form: 3,122 SF

  42. G2 – West: Conc: 55 CY Form: 3,122 SF

  43. G2 – West: Conc: 55 CY Form: 3,122 SF

  44. Tracking the Work Segments to Optimize Productivity

  45. The Results: • Exceeded budget goals • Empowered crews • Promoted safety • Eliminated waste • Promoted learning culture • Ensured peak performance

  46. Case Study Bluebeam

  47. Bluebeam

  48. The Projects: • 362,000 Amazon Headquarters TI • 5,000 SAM TI • 250,000+ First & Main GSA • The Challenge: • Efficient and timely drawing updates • Multitude of Subcontractors including owner subs • Large open floor plans

  49. The Approach: • Hyperlinked as-builts • Electronic overlays • Electronic punch list • The Technology: • Bluebeam .pdf software
