Geospatial Management of Electric Transmission Projects with ArcGIS Applications
What Is A Capital Project?
• Capital Projects are major construction or replacement projects for existing transmission facilities. Project activities include: planning, engineering, land acquisition, permitting, etc.
• Southern California Edison (SCE) manages multiple capital projects distributed over our large service territory
SCE Service Territory
• 5,000,000 service accounts
• 55,000 square miles
• 16 counties
• 180 incorporated cities
• 10+ governing agencies
2
What Problem Did We Face?
• When working on capital projects, we experienced the following problems: • Lack of GIS standards
• Reliability in deliverables
• Communication
• Reporting
• Agency requirements
• Environmental resource management
• Field data collection consistency
3
How Did We Get There?
Capital Project Data Model (CPDM)
Single managed enterprise database model with standardized schema that can be shared across internal and external organizations.
1. Identified Internal Stakeholders
2. Obtained Standards from Stakeholders
3. Created GIS Schema Standards and Documentation
4. Implementation, Training, and Maintenance

What Does The CPDM Provide?
• Consistency• Data model is utilized across all capital projects• Provide reliable data with established QA/QC processes• Standardized deliverables for all internal/external users and regulatory agencies
• Map Package• Metadata• Data Dictionary
• Ensure proper management of data• Guarantee the use of centralized, validated, and standardized geospatial data• Long term environmental data storage and shared data for other projects• Ensure accountability of data inputs
• Ability to leverage new technologies and workflows mobile device applications • ArcGIS Online• Collector, Survey123, and other GIS applications
