13 DATA SUSTAINABILITY SOLUTION

14 DATA UPDATE EVENTS Activities Installation, removal, or replacement of any assets Change in materials Change in alignment, dimensions, lengths, sizes, depth of wires/cables/circuits, location of utilities and physical features, vertical/horizontal clearances Change involving deletion of work originally planned Obstructions encountered in the field

16 City Requests Design Drawings from Consultant Consultant Submits As-Built Files City Approves or Denies Submitted As-Built Files Recommendation: Check Submissions Against Requirements Checklist Consultant Creates Requested Drawings Consultants Create As-Built Drawings Recommendation: Consultant Applies Data Submittal Standards to Digital Files As-Built Files Are Approved and Translated Recommendation: Run Approved Files through Data Translation Tool Consultant Submits Design Drawings to City Recommendation: Use Data Design Standards As-Built Data is Collected During and After Construction QA/QC on Results, Post-Process as Needed City Approves or Denies Submitted Drawings Construction of Approved Designs Begin Final Database Integration

17 CONVERSION PROCESS Receive Design Files (.dgn) Convert CAD/.xlsx to GIS Edit per As- Built Changes Add Tags to Features Input Attribute Data into Excel Integrate into Systemwide Feature Class

18 THE IMPACT

19 Current Impact Simple & Effective Approach Leverage Esri Tools Update & Maintain with Limited Resources Reduce Turn-Around on Updates Little-to-No Loss of Institutional Knowledge Improved Coordination & Accuracy with Utility Billing Improved Coordination & Process among Departments

20 Future Impact Electronic As-Builts Automated Data Conversion (CAD-GIS) Enhance & Automate QA/QC Tools Date update tools for traffic signals Leveraging other Workflows for Data Maintenance
