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 1.Reduce worker idle time 2.Prevent accidents 3.Avoid over/under design 4.Optimize just in time delivery 5.Eliminate unnecessary steps 6.Prevent defects 7.Shorten learning curve Minimize Waste

5 Optimize Delivery 1.Align goals 2.Foster trust 3.Establish accountability 4.Ensure peak performance Optimize Delivery

6 Checklist

7 Modeled Work Packages Case Study

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 ApproachTechnologyLean Objectives Fulfilled 1. Identify conflictsRevitPrevent defects 2. Visualize the workRevitEliminate unnecessary steps 3. Segment the workRevitEnsure peak performance 4. Remove obstaclesLast Planner TM Prevent defects Prevent accidents Foster trust 5. Set goalsLewis TC/WP ProgramReduce worker idle time Establish accountability 6. Provide feedbackLewis TC/WP ProgramShorten learning curve

11 The Approach: Combine the Model with Work Packages

12 Identifying Document Conflicts Virtually, Not in the Field

13 Using the Models Visualization to Plan the Work

14 Plan Forming and Pours

15 Identify Repetition for Prefab

16 4D to Fine-Tune Schedule

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

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 G1 - West Shear Walls: Broken into Segments

23 G1 - East Shear Walls: Broken into Segments

24 G2 - West Shear Walls: Broken into Segments

25 G2 - East Shear Walls: Broken into Segments

26 G1 - WestG1 - East G2 - WestG2 - East Shear Walls: Broken into Segments

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

32 Shearwalls G2 – EastG2 – West G1 – EastG1 – West

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

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

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

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

45 Tracking the Work Segments to Optimize Productivity

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

47 Bluebeam Case Study

48 Bluebeam

49 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

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

51 SharePoint Case Study

52 SharePoint

53 The Project: Shorenstein property 250,000+ First & Main GSA LEED gold TI 5 month duration 6 agencies over 12 floors The Challenge: 6 contracts with 6 separate document streams 5 architects, 4 engineers 24hr turn on submittals and RFIs

54 GSABldg OwnerLewisSubcontractorsA/E VBA Corporate VBA LocalDEA Corporate DEA Local OIG Corporate OIG Local AFR Corporate AFR Local IRS-P Corporate IRS-P Local IRS-T Corporate IRS-T Local Project Tenants

55 Traditional Approach: 6 couriered hardcopies / FTP sites Separate tracking/Log comparison Waste: Delivery time Lost or inadvertent deletion of Time spent tracking documents Working with the wrong file Confusing FTP sites

56 The Approach: Go digital The Technology: Utilize SharePoint to organize, distribute and track project documentation Sub Submit to Lewis Lewis Review Submit to Architect Arch Review Return to Lewis Lewis Return to Subcontractor Team Review Respond

70 Live Shared As-builts

71 The Result: Faster document review Reduction in Cost Report turnaround time Effective Meetings Less paper use Using Lewis SharePoint as a portal between the design team and contractor really helped to streamline the document exchange process. Given the compressed timeline of the GSA projects, I don't think we could have been able to meet the schedule without SharePoint. I would gladly use it again and would look for ways to implement a similar technology in my own organization. Whit Middlecoff, AIA GBD ARCHITECTS Incorporated
