3. Key Learning's Why compatible units? The make up of compatible units @ PG&E Using compatible units entirely within SAP for estimates Using compatible units in conjunction with 3 rd party design tools Scheduling & CU’s Special Use’s Assemblies Pitfalls and cautions when handling CU’s

4. Best Practices Compatible Units drive consistent use of standard material and lowers procurement costs Compatible Units used within Design Templates drive standard designs Standard designs drive standard construction practices Standard materials drive standard maintenance procedures Unit costs readily available

5. Why SAP Compatible Units?: It is more then just about labor hours and materials. SAP compatible units enable the use of: Functional Locations Equipment Records Crew Classes Services Special Equipment Assemblies

6. Workflow Diagram: Work Order Confirmation and Settlement Work Order DesignCU Library Create & Change CUs Design Work Orders based on CUs Confirm Work Orders Settle Work Orders Final Evaluation of CUs Based on Confirmation and Summary Process

7. The Notification/Order Hierarchy @ PG&E Notification –Master Order - (Used to schedule non construction tasks) CU Design (Collection of all CUs for the job) –CU Order – (CU Design exploded into:)  Operations  Components (Material and Services per operation)  Settlement receiver per operation  User fields on Operations (MAT, X, Y… )

8. The Notification/CU Order Hierarchy (Example)

9. Notification Master Order CU Design As-Built Schedule Labor (Click) Material Reservations (MM) Application for service Job Estimate Package Initiate Design Construct Document CU Order Preliminary Estimate Contract (CCBS) Equipment Record Workflow CU Library Settlements Future

10. Design Construct Document Report CUs and the Work Management Process 3 Interfaces with external Graphical Work Design tools Standardizes materials used in construction Used within standard CU Design Templates Used to create Job Package (Job Estimate and Supporting Reports) Links Job Package to DMS Automatic AIN accounting determination for CCBS (contract program) Determines AIN costs and interfaces with CCBS Used with custom trench application to calculate resources and allocate costs Automatic order creation based on CU Design Provides cross validation for CU characteristics Provides the ability to create and cost multiple designs Interfaces with Click scheduling based on CU Attributes for crew class and size Provides flexibility for scheduling labor and materials Provides the ability to create work ticket for construction Material visibility and demand automatically sent to MM system (forecasting) Automatic Material reservations in MM system Automatic Settlement Rule creation at the operation level Automatic Equipment Creation during the AS-Built process Provides the ability to compare AS-Builds with Designs Automatic Mass Asset interface to CO module Facilitates the automation of unit costs Provides the ability to more accurately report costs by MAT for program owners Provides more detailed reporting capability based on CU Attributes (Ad Hoc)

11. The Elements of Compatible Units @ PG&E  Primary Characteristics  User Fields on CU Instance  Secondary Characteristics  Settlement rules  Virtual CU’s  CU Hierarchy  CU Summarization  CU ties to scheduling  Custom functionality – Trenching  Materials - CU’s. (components/reservations)

12. Compatible Unit Search Criteria Reference Object : Functional Location Equipment Record Task List Labor Time Work Center (Crew Class) Material Activity Type Design Time Attributes : CU Type (Pole, Pipe, Conductor…) Action (Install, Remove, Transfer, Abandon) Unit Application (Distribution, Service, …) Service Type (Gas, Electric) Work Agent (PGE, Applicant) Maint. Activity Type(16R, 29J, …) Job Rule (New Business) Tax Location(Private, Franchise) Assemblies: Compatible Unit Structure

13. Example Compatible Unit: (45’ Class 4 Pole) Classification Task List Reference Object : Functional Location Equipment Record Task List Compatible Unit

14. Example Compatible Unit: (45’ Class 4 Pole) Task List Labor Time Work Center Activity Type Material Install Remove

15. Example Compatible Unit: (45’ Class 4 Pole) Material

16. Example Compatible Unit: (45’ Class 4 Pole) Classification Task List Reference Object : Functional Location Equipment Record Compatible Unit Reference Object : Functional Location Equipment Record

17. Example Compatible Unit: (45’ Class 4 Pole) Reference Object : Equipment Record

18. Example Compatible Unit: (45’ Class 4 Pole) Reference Object : Functional Location Equipment Record

19. Example Compatible Unit: (45’ Class 4 Pole) Classification Task List Reference Object : Functional Location Equipment Record Compatible Unit Classification

20. Primary Characteristics and User Fields Primary Characteristics and User Fields describe How and Why the CU was used in the Design. Only one Primary Class can be assigned to CUs Primary Characteristics:  CU Type (Pole, Pipe, Transformer)  Action (Install, Remove, Transfer, Abandon)  Unit Application (Distribution, Service, Transmission)  Service Type (Gas, Electric)  Work Agent (PG&E, Applicant)  MAT (Maintenance Activity Type)  Job Rule  Private/Franchise Caution: How you use Primary Characteristics can complicate CU Maintenance

21. Primary Characteristics and User Fields (Cont) This information is used to determine: Which operations to select from the CU task list and transfer to the CU Order The settlement receiver at operation level Accounting for contracts How to schedule labor and material Detailed information about how labor and material are used to enable more accurate reporting capabilities.

22. Example Compatible Unit: (45’ Class 4 Pole) Primary Classification

23. Secondary Class Characteristics CUs can be assigned to as many secondary classes as necessary. Used for classifying the CUs to enable searching capability.  By Standard  By Attributes Pole Height Class Material, Etc. Also can be used to drive other custom logic and reports  Mass Assets Used for assembly definition (variant configuration)

24. Example Compatible Unit: (45’ Class 4 Pole) Secondary Classification

25. Example Compatible Unit: (45’ Class 4 Pole) Classification Task List Reference Object : Functional Location Equipment Record Macro Compatible Unit Create Macro Cu

26. Macro Compatible Unit

27. Assembly Configuration Options Variant Assemblies (Uses Variant Configuration) Macro Assemblies (User Exit) CU Designs as Assemblies (Custom Code)

28. Creating Estimates Using Compatible Units within SAP: Design Templates/Tabular Designs Virtual Compatible Units (VCU) Design Points Cost Simulation Job Package creation Custom Application (Joint Trench) Example

34. Special Use’s

36. Using Compatible Units In Conjunction with Design Tools Requires 3 interfaces for External Tools  Export CU Library to external system Labor, Material, Services, Primary and Secondary Characteristics per Compatible Unit Validation Rules  Link Master Order to External Design  Import external design to SAP Creates SAP CU Design Passes CU with Primary Characteristics Passes implementation defined Characteristics Respects the defined CU Hierarchy within the CU Design

37. Using Compatible Units In Conjunction with Design Tools SAP R/3 CU Library Master Order Construction Measure CU Order CU Design External Design Tool CU Library Design Creation Completed Design Export CU Library Link Master Order to external design Create CU Design

39. CU Summarization Process LD-PROSAP DETAILED CU DESIGNSAP SUMMARIZED CU DESIGNCU ORDER Key Functional Requirements 1.Summarize all non-trench, non-equipment CUs that have the same primary characteristics and CU ID 2.Summarize all the like trench CUs including facilities 3.Do not summarize CUs that create equipment records; keep them at design point 4.Do not summarize other CUs identified as ‘Do not summarize’ Detailed CU Design Summarized CU Design CU Order 3. Dsgn Pt 1 Wood Pole 4. Dsgn Pt 2 Cut-to-Length Cable 1. VCU: Non-trench, Non-equipment (Bends, Crossarms) 2. VCU: Like trench CUs including facilities (Excavation, Sand Backfill, Pipe) Construction Measure Master Order KB Object Application/Notification

40. SAP recommends not exceeding 2000 operations on a single CU order PG&E’s current configuration will allow up to 4500 operations on a single CU order The table below shows the expected decrease in number of operations after CU summarization: With CU summarization, we will be within SAP’s 2000 operation recommendation for subdivisions up to 400 lots Approximately 5% of designs passed each year will be this size or greater Proof of Concept Subdivision# Operations # Operations after summarization % Reduction 11 Lots46014568% 60 Lots242830088%

41. The Roll of CU’s For Scheduling: PG&E uses Click Software for external scheduling Specific operations used for scheduling (Prevents scheduling from seeing unnecessary operations) The ability to group operations based on CU Characteristics Schedulable operations carry hours, crew class etc. Crew class by work center – (Alt: Primary Char.) Material Delivery

42. Schedulable PM Order Operations

43. Planning CU/Order Example: Use CUs to create typical CU for each MAT (Maintenance Activity Type) –Use typical labor classes (Activity Types) Estimators/Designers Mappers Electric Construction Gas Construction –Use major material Use Planning CU in Planning tool

45. Lessons Learned and Challenges Cross validation of characteristics CU Summarization Master order vs. CU order settlement arrangement. Keep CU construction as generic as possible Add necessary business/financial attributes upon use of the CU in your CU Design object. Assembly creation is as much an art as a science. Future needs: –Maintenance Tools –Assembly construction hierarchy
