3. Agenda Adaptive Capital Planning Winston-Salem’s Adaptive CIP
Overview of the Master Plan
Goals for Developing the iCIP Tool
How the iCIP Tool Works

4. Adaptive capital planning

5. Adaptive Capital Planning
Focus on Asset Management & Optimization rather than Expansion
Need for cost-effective assessments
Address worst condition assets first
Risk based prioritization
Planning for Growth alongside of Budgeting for Maintenance

6. CIP Prioritization - Old approach
Traditional CIP
Static CIP Report
Time and situation constrained
Not risk-based
Not adaptable
Adaptive Capital planning

7. Factors that can affect Planning
Growth Rates
Asset Condition
Outside Factors

8. Winston-Salem’s Wastewater System Master Plan

9. City/County Utilities Commission – Collection System Overview
1,724 miles of sewer main
49 Pump Stations
Two Treatment Plants
Muddy Creek (21 MGD)
Elledge (30 MGD)
Three Major Sewer Basins 9

10. Wastewater System Master Plan
Evaluate collection system capacity in three major basins
Prioritize Capacity improvements
30 year Master Plan (2011 – 2041)
Future Treatment Alternatives Evaluation
Collection System Asset Evaluation
Wastewater System Evaluation
Capacity Driven Projects
Condition Driven Projects
CIP Projects 10

11. Developing the cip Projects
Capacity Driven Projects
Flow Projections
Field Surveys and Flow Monitoring
Hydraulic Model for Base and future Years
Condition Driven Projects
Facility Inspections
Pipeline Prioritization
Criticality Ratings based on consequence of failure
Condition Scores evaluated based on available data, modeling results, and age of pipe

12. Asset Management approach to system planning
Provides a comprehensive and coordinated Master Plan CIP

13. …But How final is the “final” CIP?
What if…
A routine pipeline inspection reveals a pipe failure at the location of a future capacity project? OR
A 2020 DOT project includes tearing up and repaving the road at a sewer crossing in the 2030 CIP. Does it make sense to move forward the project? All of the project or maybe just the road crossing?
We need to compare alternatives and update the CIP!

14. Adapting the cip using the iCIP tool

15. Customizing iCIP for Winston-Salem
Evaluating Current Needs
Critical Capacity Driven Projects
Long-Term and Short-Term Budgeting Tools
Increased functionality for Cost Estimating, Project Scheduling, and Cash Flow and Spend Plans
Data Collection Plan
Evaluating Future Needs
Asset Condition Database
Prioritize Inspection and R&R budgets 15

16. Adaptive approach to CIP Prioritization
Three Components
Asset Prioritization – Leverage GIS Inventory and updated condition data to prioritize projects (GIS)
Asset Costing – Dynamic update costs based on project changes to scope and schedule (Excel)
CIP project identification (iCIP)

26. Phasing is Based on the Start Year and Project Duration26

28. Adaptive CIP An Adaptive CIP can…
Leverage risk-based prioritization and/or capacity assessments
Immediately see results of decisions graphically
Easily integrate with existing and updated GIS asset inventory
Provide tools to adapt to changing budgets, asset conditions and priorities 28

29. In closing… An Adaptive CIP can respond to…
Growth – Whether a recession slows growth or a housing boom in an unforeseen area accelerates growth, CIP projects can “slide” to when they are needed.
Condition – Prioritization scores can be continually updated and used to allocate resources efficiently
Outside Factors – Updates can be made to take advantage of developer projects, transportation projects, etc 29
